Pollution, in today’s world, is considered one of the foremost problems. It is slowly killing the planet from the inside out. One of the major aspects of this is air pollution. Yes, the very air we breathe is not pure. It is toxic, full of pollutants, and often harmful to our physiology. Since there is no way to control the pollution of air at large, the best we can do is control the air which centers and circulates within our homes. This can be achieved through the action of wondrous machines known as Air Purifiers.
The working of an air purifier is rather simple. It uses powerful fans inside the mechanism to pull in the impure air into it and forces the air to pass through a number of filters, making it clean and pure to breathe, and then releases it back into the room. Over a certain period of time, the air is passed through these filters numerous times, making the majority of the air safer to breathe. This is basically how air purifiers achieve purer, safer air.
There are a few types of air filters, including
- HEPA filters,
- ozone generators,
- electro-static filters,
- UV Light Filters and
- Activated Carbon Filters.
All of these serve the same purpose, in varying ways. They clean the air, remove irritants, remove pollutants, and even neutralize smoke particles. If a household has a pet, it is bound to shed, which are also removed by the purifier. Dust is restricted and germs are not allowed to spread, as they are sucked into the mechanism. For a person with allergies, this is an essential buy.
In the seasons of spring and summer, due to pollen and other allergens, such people suffer greatly. The air itself is laden with irritants and this cannot be avoided without an air purifier. The purifier removes all these pollutants and allows the user to breath clean and pollutant free air.

Also, there are a few variations of the filters; some of the purifiers use a combination of filter. Those types of purifiers are capable of eliminating more than one type of pollutants; they are very modern and considered the most effective ones.
But first, do you really need an Air Purifier?
If you just simply put it, an air purifier is an air cleaning machine. It blocks all the contaminants from the air making the air breathable while improving the indoor air quality.
Air purifiers are also medically preferred as they’re known to reduce allergy symptoms, asthma and other breathing abnormalities. It even improves your sleep and makes it easier for you to breathe; basically, improves the living standard.
Contrary to the popular believe that an air purifier is only needed if you live in polluted city is wrong, you will need it anyway if you wish breathe fresh air. The fact is, the air all over the globe is polluted. The level of pollution differs from city to city. But it is polluted.
Whenever you open the door or windows of your house that polluted gets inside your house and gets trapped. Those dust particles also gets stuck on our clothes resulting us breathing in such polluted air even inside our house.
Even without the outside influence, there are a lot of indoor pollutants making the air inside the house, tainted- starting from furniture materials, paint, cleaning products, pet dander, mold and even more.
So, just because you live in a certified clean city does not mean that you actually don’t need an air purifier. It is a great investment for every home regardless of your address.
Before you try to purchase an air cleanser or a purifier, read the issues listed below. A few of them may sound very familiar and it will help you choose the perfect device.
Do you experience any of these?
- Are you facing seasonal allergy symptoms or possible related to pet dander?
- Are there anything around your house that is causing your asthma symptoms to flare up, but sadly you are unable to figure out the source?
- Is there a renovation work going on in your house, and all those dust and paint fumes are nauseating you?
- Are you prone to cold?
- Do you just want to disinfect your home by killing all the bacteria and viruses?
- Do you have any pets who are shedding dander or source of any odor?
- Do you want to get rid of tobacco smell or any sort of smell?
How to select the Best Air-Purifier for your Home?
Now that you are aware of how important is an air-purifier, what pollutants do they fight, the filter types and their certifications we can further proceed to select the right type of air-purifier that will serve your purpose.
1. Air-filters according to individual requirements
- Purifier to deal with allergies-if you are suffering with allergies then you should purchase an air purifier that is equipped with a per-filter and a proper HEPA filter. This is the top combination of filters that is capable of trapping all the allergens found in the air such as pollen, duct, pet dander and even mold spores.
- Purifier to fight molds-first of all, it is a terrible news if you have mold in your house. But in order to deal with that you should get a purifier that is equipped with the combo of a true HEPA filter, ultra Violet Light and an Activated Carbon filter.
The True HEPA filter traps the mold spores then the UV ray completely destroys the mold DNA and finally, the activated carbon filter eliminated the odor the mold.
- Purifier to eliminate pet hair– if you are riddled with pet dander and want to get rid of them, then you should buy an air purifier that is equipped with a True HEPA filter or a HEPA type filter. The size of a pet dander is just 50 micron and these HEPA filters are capable of catching particles that are as small as 0.3 to 2 microns.
- Air purifier for smoke- if you are bothered with smoke then you must get an air purifier with a True HEPA filter and Activated Carbon filter. The true HEPA filters are known to capture 99.97% of smoke particles and the activated carbon filters removes the odor.
- Purifiers to eliminate germs– you need to purchase an air purifier equipped with a germicidal UV-C light. This specific UD light is capable of killing viruses and it also destroys their DNA structure. But you can also get a HEPA filter; they are second best as they are only able to trap the viruses and stops them from entering the air again.
2. Choosing the right Size Air Purifier
Another important thong to consider is the size of the purifier which is most of the times neglected by the consumers. But you need to know which purifier is the best for your home and for your health.
First, you need to check the square footage rating on the packaging, and then you need to compare it to the size room where it will be placed.
If the square footage rating of the purifier is equal or greater than the size of the room then it was definitely an excellent choice by you.
But, here’s the proper way to measure it;
You will need the measurement like the width and length of the room in feet and if you multiply them, you will achieve the total square footage.
So, the calculation is; 10′ x 20′ room = 200 sq. ft.
If you have multiple connected rooms, such as a living and dining room and a kitchen, then you have to make additional calculations. You just have to add up the total area in square foot.
So, the calculation is; 10′ x 20′ living room = 200 sq. ft., 10′ x 10′ dining room = 100 sq. ft., and finally, 15′ x 20′ kitchen = 300 sq. ft. The together you will get (200 + 100 + 300) equals 600 sq. ft.
So, after completing the calculation you need to know the minimum sq. ft rating of the purifier in order to learn its efficiency.
3. ACH and CADR ratings
Well, you are trying to purchase an air purifiers so you will most definitely come across two of the very common and specific ratings;
Air Changes Per Hour or ACH
The ACH rating is most of the times it is ignored by the customers as they are unable to understand it. Unfortunately, this particular rating tells the customers the efficiency of the air purifiers.
The ACH rating stand for the rate of exchanged air in the room by the purifier every hour. The rating includes 4X, 5X or 6X denominations. 5X means that the polluted air in that particular space gets trapped and then recycled within 5 hour interval. The higher the number, greater the efficiency of the purifier!
You also need to know that this rating is directly linked to the max sq. ft the purifier can handle. So, if the purifier has a 5X rating and specified that it can cover 300 sq. ft. specified efficiency.
Clean Air Deliver Rate or CADR
This is the second we mentioned. It was developed by the Association of Home Appliances Manufactures in order inform the potential customers about how capable is the air purifier to clean the air inside a particular room.
The objective was to provide a standard which will help the customers to equate the effectiveness of a particular device. This rating is even more important due to the fact that we usually compare two or more purifiers against each other before getting one.
The CADR rating mainly provides us with an honest assessment regarding the capacity of the air purifier. Duet, Tobacco Smoke and Pollen; these are the three types of pollutions measured by the CADR rating.
If the number is high then the efficiency of the purifier is also higher.
4. Portable, Whole house or Commercial Use?
There are several varieties of air purifiers found in the market. Some of them cleans air by removing dust particles, molds and other allergens. So, we have compiles a list of our own of different type of air purifiers.
- Portable Air Purifiers
These are also called room air purifiers. It does not need any heating or a cooling system. Best suited for bedrooms and they are also very cheap but their efficiency is amazing.
- Whole-house Air Purifiers
You can also go with the whole-house purifiers. These purifiers are usually gets attached to a heating or a cooling system. They are capable of clearing big rooms and clearing allergy related issues.
- Commercial Air Purifiers
These purifiers are capable of removing a large number of contaminants from the air compared to standard air purifiers. So, if you are using a commercial purifier you must have to use it in a big room or for a long hallway.
Such systems come with PCO and HEPA filter for protection against any type of harmful bacteria, chemicals and viruses.
5. Air Purifier Features You Need to Look
Here, we are going to tell you what you should look for while purchasing an air purifier. If you compare two or more machines together you will find that there is a wide variety if you include the additional features and customized upgrades.
So, some of these features will cause some extra buck and learning all these things will definitely help you to purchase the best product suitable to your need.
Here are the features you need to look for in an air purifier;
These type of filters are capable of trapping the largest particles in the air. So, if this one is attached as an additional filter to your purifier, it will increase the lifecycle of the inner filter significantly. The Pre-filters are also very cheap and they are washable.
- Digital Controls
The digital control will allow you to control and manipulate the settings of the purifier more precisely.
- Adjustable Fan Speeds
Most purifiers come with a fan speed settings of 2 to5. The highest and the lowest range exist somewhere between them. Some purifiers are also equipped with turbo speed to accelerate the cleaning process.
- Filter Replacement Indicators
Some filters are equipped with indicator that informs you when it is the right time to replace the filters. It simply means the filters are filled with pollutants; you need to change or wash them in order to make them work perfectly.
- Programmable Timer
The automatic turn off feature is available with almost every purifiers, these days. It simply helps to same electricity.
- Carrying Handle
The carrying handles make the transportation of the purifier very efficient. It is a very heavy device so the addition of a handle is preferable.
Works more like the handles, the casters are a set of wheel mounted below the purifier making it easier to move.
- Antimicrobial Treatment
This is a type of coating found on purifiers. It helps on preventing the spread of bacteria and microorganisms on internal filters, resulting an increase in the lifespan of the filter.
- Air Quality Sensors
This sort of sensors are capable of monitoring the air, they look for specific pollutants and then adjusts the in order to remove those particles immediately.
- PlasmaWave Technology
An alternate method of ionizing the air! So, that it does not emit negative ions or worse produce ozone. This technology uses water vapour to achieve the same results.
- Photocatalytic Oxidation (PCO)
A very advance filtering process, equips the filters with UV Light in order to completely destroy the chemicals or other volatile organic compounds; even bacteria, mold and fungi.
This light helps to locate the purifier inside a dark room.
- Remote Control
If you have this, then you will be able to operate the purifier from a significant distance.
- Mobile App
This is the age of app. They are almost everywhere, capable of doing anything. So, the addition of app will provide you with the full access of the purifier via your cell phone.
6. Other Considerable Points
This is the final stage of making the decision, which air purifier to get for your home. But there are some additional points to consider before you get to do that.
- Cost of Maintenance
If you simply maintain the purifier properly then they will work most efficiently. So, before getting the purifier make sure you know how much it will cost to keep it running smoothly.
The purifiers that are equipped with HEPA or Carbon filters needs replacing frequently. These filters trap the particles so eventually they get clogged up when they can’t clean the air anymore.
The HEPA or Carbon last about a year before they need replacing. So, find out the replacement cost. If you get the ionic air purifier you don’t have to worry about the maintenance. As these machines are equipped with a type of electrostatic collection filter to collect pollutant particles from the air, but these filter are washable and reusable.
- The Noise Level
If you get an air purifier equipped with a HEPA or a Carbon filter then you will see that those purifiers come with a fan. This fan sucks the air into the filter and then forces the clean air back into the room. Sometimes, it may feel like that these fans are making too much noise.
But if you reduce the fan speed then the noise level will also be reduced.
Generally, purifiers have only two speeds; high and low but there are few that are equipped with close to 5 type of speed like low, medium, high, turbo and automatic.
So, the noise level is a very important factor. If you are going to be using it in the bedroom, high level of noise will make the air clean but it will not let you sleep well.
So, go for a purifier that is properly sized for your preferred room. If it is too small then it will work too hard and the noise will be higher. As it will be operating at its highest setting!
But the ionic purifiers do not use filters and it also means that they don’t use fans. So, these types of filters are the best choice if you are looking for a low noise purifier.
- Consumption of Energy
Similar to other appliance in your home air purifiers will be plugged to your wall and will be running on electricity. As they require to run 24/7 for maximum efficiency, you need to consider the amount of energy it will require. Generally, the purifiers use 50-200 watts of power. But we would recommend to get a device with Energy Star rating. It ensures that the power consumption will be low.
There are several manufacturers all over the world know for designing air purifiers for homes. Sadly, not all of them provide high-quality machinery. So, if you are getting a purifier, it is important to know the manufacturer. Just select a manufacturer with good background and reputation.
Another thing you need to look for before purchasing the purifier is the warranty. It will help you to avoid any issues in the long run. Just learn what are covered and for how much time, if they turn out to be defective.
You need to remember that the air purifiers are a long term investment; it is not something that you can purchase every other month. And obviously no one wants a product that faulty but still this is an electronic product, you don’t know what’s going to happen until it happens. So, a valid warranty is important to protect the repair or the replacement costs in case it turns out faulty.
What are the variations of Air Purifier Filters?
There are different variations of air purifier filters available; each one is dedicated to eliminate a particular type of pollutant. So, before you purchase them know how many types of filters are available and what is their target pollutant?
Needless to say, each variation of the filters has their strengths and weaknesses which is why the modern purifiers are equipped with two or more type filters in a single unit.
1. HEPA Filtration (High Efficiency Particulate Air)
This type of filtration process is considered the highest level of purification process. The U.S HEPA standard was developed long ago by the Atomic Energy Commission. Their goal was to capture the radioactive dust particles.
There is a variation of it, name the True HEPA Filter, they are known to remove more than 99.97% of all the microscopic particles, even if they are as small as 0.3 microns. So, these types of filters can allow only the very small particles to pass by thereby, allergens like pollen or pet dander or mold spores or even dust particles will be eliminated.
Sadly, all the HEPA filter are not created equally. Here the size matters, the more square footage in a HEPA filter the more number of particles it will be able to remove. The size, material and even the manufacture all varies and plays a key role into it performance.
This is probably the main reason why one HEPA filter is more expensive than the other. So, when you are getting a HEPA filter you need to look for the HEPA label specifically.
Pollutants removed – pollens, mold, dust, pet dander, hair, and even smoke.
- Top certified filters
- Trap all type of particles of very small size and does not let them release into the air
- It is suitable for different respiratory issues
- Requires regular maintenance and replacement for maximum effectiveness
- Most expensive filtration system
- Incapable of removing odours and chemical fumes
- It employs a fan in order to suck in the air at the highest rate which can be very noisy
2. Carbon Filtration
Another variation of air filters is called the Activated Carbon Filters. These sort of filters are not really used alone to purify the air, it is a very rare occurrence. Usually, they are accompanied by other filters. These activated carbon filters excels at eliminating or absorbing irritating odours. They are also capable of neutralizing smoke, chemicals, and fumes.
The activated carbon filters use a very specific form of carbon containing millions of very tiny pores, these pores are very absorbent. As it consists of so many pores, the surface area is exceptionally large which inherently traps all the fumes, gases and odours.
You may not know this but if you simply treat carbon with oxygen, millions of pores will be opened on it. These are very small microscopic pores which make the surface area of the carbon very large. Thus a single pound of activated carbon has a surface area of 60 to 150 acres.
As it has such large surface area, it is best suited for absorbing gases and odours. That generous surface area is just perfect for bonding with molecules of chemical or vapour. When the carbon filter is larger, then the amount of chemicals absorbed by it will be higher and it will also be able to work for an extended period of time. After it is full, it will no longer be able to absorb chemicals and then you have to replace it.
Pollutants removed – chemical and gas fumes, odours, smells originating from pets, cooking, smoke and smell of paint and the smell from cleaning products
- Helps to keep a room fresh
- Compared to other filters it is cheaper
- Effective for people living in industrial areas
- Only useful for removing gaseous fumes, smells and odours from the room, there are no other applications
3. Ionic Filtration
This is a completely different type of filtration system. This type of filter emits a charged cloud of in the air, the ions present inside the cloud get attached to the impurities present in the air and it forces them to cling to the nearby surface.
As it does not eliminate the impurities, it forces them to get attached to a surface. But this process is also capable of eliminating ultra-fine particles sizes as small as 0.01 microns.
A few ionic air purifiers are equipped with an electrostatic collection plate. This plate attracts the fallen particles in order to remove them from the room.
Pollutants removed -dust, pollen, mold spores, volatile organic compounds, fungi, different bacteria’s and viruses, also visible smoke.
- This filter is practically maintenance free; you don’t need to replace it.
- It is lot cheaper
- Noise free.
- Pollutants stays in the room cling to the surfaces. Unless you have an electrostatic plate or a collection plate you can’t remove them.
- Needs cleaning very frequently
- It is not capable of eliminating odours
- Produce small amount of ozone as the by-product which is not really good for health
4. Ultra Violet or UV Light
This is unlike any other filtration system we have mentioned before. There is actually a UV lamp inside the purifier. It emits an invisible light that contains UV light. This light attacks the pollutants as they are passing through the filter.
The bulb is of 20 watt and it emits UV that kills pathogens, germs, and microbes. It is also certified by California Air Resource Board, making the process ozone free.
This sort of setup, like air purifiers equipped with UV filters is generally used inside the hospitals, in order to keep the environment sterile. They can also be used in the kitchens, laboratories or even at the day-care centres. If you have the tendency to get sick very often then you need this air purifier equipped with a germicidal filter or UV lamp may. It will boost your immunity.
The main work of the UV ray is to completely destroy the bacteria and viruses at the molecular level. What you are getting is a pretty good sterile environment with clean air.
Pollutants removed– all sort of micro-organisms as bacteria, viruses, germs.
- These filters are capable of lasting for thousands of hours and rarely requires replacement
- Creates a sterile environment, cuts down the number of germs inside your room
Disadvantages of Ultra Violet Light Filters
- It is capable of only killing the viruses, bacteria and germs. So, this filter can’t be bought as a standalone device.
- Mostly comes as an attachment with a HEPA or an Ionic air purifier
This is a completely different type of air purification system and it is not good for health. This type of purifier manufacturers Ozone gas intentionally. Although, there are article and statements which are made to make you believe that these devices are safe for public use but they are not, actually.
Several health professionals have spoken against such claims and they have stated that there are no such agencies authorized by the federal government to manufacture such devices. If you get exposed to ozone, it may aggravate your asthma symptoms and if you consume it in high levels then it is sufficient enough to create scars your lungs.
Sadly, there are still different brands Ozone air purifiers available in the market and the amount of Ozone produced by them obviously varies but you also have to know that there are several chemicals we use every day that reacts to ozone. Several studies have shown that the ozone air purifiers help in the growth of a few specific biological agents. It is also impossible for it to clean the in such low concentrations.
What are the Most Common Source of Household Air Pollutants?
You have to remember that different purifiers are designed to tackle different type of pollutants. So, it is imminent to identify the type of pollutants that is currently polluting your air, before you finally purchase an air purifier.
- Allergens- in the list of airborne particles you will find pollutants like pet dander, mold spores, dust mite allergen, plant spores, fungi and pollen. These are identified as the most common source of allergy and asthma attacks in every household.
- Smokes-the smoke of tobacco or weed can be very irritating for non-smokers and it is one of the most common causes of indoor air pollution.
- Odours-the odours inside the house are a big problem. It includes the smell of gasses, kitty litter, various toxins, and gaseous pollutants like indoor pesticides, aerosols, and chemical cleaners. Such type of pollutants is very common and hard to eliminate.
- The VOCs- VOCs or Volatile Organic Compounds are available in most in most of the common household products such as; paints, varnishes, cleaning supplies, disinfectants, glues and adhesives, and even new carpets and building supplies are not excluded. You need to find the components like benzene, chloride, formaldehyde, ethylene, and toluene. The Volatile Organic Compounds can cause several symptoms like the irritation of the eyes, nose, and throat, headaches, nausea, and even severe chronic health conditions such as damage to the nervous system. It can also aggravate asthma.
- The micro-organisms- such category includes antigens, pathogens, bacteria, and obviously viruses. These are the most common germs that make us sick. These also include mold, fungi and protozoa other microscopic plant bodies causing several health issues.
All these pollutants are considered dangerous. They can damage your health, and it does not matter if you have a very specific type of allergy, they will cause damage and even aggravate your respiratory issues. The only difference is that the people who are directly affected by these elements are able to notice the effects almost immediately but those who are not allergic to such contaminants won’t be able to notice the changes immediately, resulting serious health damage in the long run.
Frequently Asked Questions?
Well, not to worry, the Air Purifiers are designed to fit into any large or small spaces. All you have to do is to measure the square footage of the area of the room where it will be used.

We can assure you that air purifiers are a safe piece of machinery you can use it in your house without any worry. But there is an exception to this statement, there are purifiers known as ozone producing air purifiers. Such purifiers can cause irritation, allergies, aggravate your respiratory problems, chest pain, cough and even severe lung damage.
The HEPA purifiers are very popular and they are ozone free. You can also use ionic air purifiers and never get confused with ozone air cleaners.
Usually, most of the air purifiers available in the market are designed to clean only a single room. So, we would suggest that you keep it in a room where you spend most of your time, in most cases it is the bedroom. Although, if you have a home office or any other room where you spend most of your time, you can place it there.

As per the instructions provided by the manufacturers, you will need to use it continuously throughout the day.
But when you first turn it on, you should set it at the highest settings, then after a few hours you should change it to automatic. The purifier will adjust.
But once you are sure that the air at that specific location has been purified you can change it to the lowest setting, even then the air space will be cleaned.
Usually, you only require one or two purifiers in your house. The most ideal way is to get one for the living room and one for the bedroom as these are most used places inside any house.
Unfortunately, air purifiers are not designed to clear the air between two rooms. They are not that powerful. Still, if you have such space in your house, you need to get one purifier for each room, only then you will get good results.
Most of the purifiers come with an indicator light which alerts you if it’s time to change the filters. Unfortunately, not all the purifiers comes with such convenient feature. If you have such device in your house, you need to check the manual to find out the recommended time of effectiveness for the filters. If that time has passed, you will have to change the filters. The time of filter change varies between three months to a year.
Most people think that it will be very difficult to change the filter of an air purifier whereas it is quite simple. If you simply remove the front plate of the purifier then the filter will be visible to you. But there are also other purifiers that features a filter at the side or at the backside of the purifier.
Fortunately, for you either of the variations does not require any special tool or skill to change the filter. If you are still having problems, read the instruction manual, provided with the purifier.
The machines like air purifiers are designed to operate in a closed room, for maximum efficiency.
The air purifier eliminates all the harmful contaminants from the air like dust particles, pet dander, bacteria etc. making the air breathable for you. Unfortunately, if you open the windows of the room, the contaminated air from the outside will get mixed with the purified air inside your room. The purifier will continue purifying the air as long as there are impurities in the air but ultimately you are not getting to breathe the clean air.
So, never ever leave your doors or windows open. Besides the above issue it will also put immense pressure on the purifier.
The clean-up of an air purifier is extremely easy. If you are still having problems then read the instructions below;
