There are mainly two types of air purifiers based on their technique. These are active air purifiers and passive air purifiers.
Air purifiers with active purifying techniques carry out the work using negatively charged ions. These ions are released in the air and cause them to attract the impurities to increase their weight. This helps in making them fall on the floor or get attached to the wall. So the impurities don’t remain suspended in the air, and the air gets cleaned.
Passive air purifiers carry out purification using air filters for removing the impurities from the air. Since the negatively charged ions might loosen their bonds with the impurities with time, the impurities enter the air after some time. Thus, passive air purifiers are way more efficient.
We need to consider the following features when buying an air purifier:
- Area Covered: This is probably the very first thing one should consider while buying an air purifier. This will decide how many air purifiers you’ll need to cover a desired area.
- Capacity: The capacity of the air purifier you buy will decide up to what extent it can purify the air. One should invest considerable time to know which air purifier suits best in the space required.
- Filter Types: You also need to choose the filter types. There are air purifiers that come with different types of filters. They are all designed to purify the air, but their working principle is different, so is their efficiency. HEPS is considered the best. But there is also Activated Carbon filters, Ion Filters, Ozone Generators, and more.

How To Choose The Best Air Purifier?
The best possible ways to upgrade indoor air quality is by removing the pollutant sources and the ventilation of the clean air throughout the space. Portable air purifiers can help with this when the traditional and conventional methods of maintaining the air quality seem to fail. These are also known as air sanitizers, and these also filter the air in one room, not the entire home.
These Air purifiers help in eradicating the air pollutants which are present in the indoor air. These appliances are considered to be important nowadays, especially for people who have asthma, as well as lung and kidney disorders. As different air purifiers are designed for different purposes, each of them targets a different area. Hence, it is important to invest in an air purifier which suits the needs and requirements of the people.
1. Types of Air Purifiers
To deal with Indoor pollution, there are quite a few technologies made available in the market. Some of these are mentioned below:
- HEPA Filters:
The HEPA filter purifiers are considered the best among the air purifiers. HEPA stands for High-Efficiency Particulate Air. These type of air purifiers comes with very dense paper filters. This filters trap any type of airborne particles.You will find a lot of filters that carry the name HEPA, but you need to look for the filters that come with official HEPA certification. The label will say, ‘True HEPA Filter’. A true HEPS filter is capable of removing 99.97% of all microscopic particles in the air, even particles as small as 0.3 microns.Other HEPS filters use the term ‘HEPA-Type’ of ‘HEPS-Like’ compared to true HEPA filters; they are inferior. These filters are capable of only filtering particle that are within 2.5 microns.
- Activated Carbon Filters:
Instead of taking hold of some of the dust and bacterial particles, activated carbon acts as a sorbent material. It tends to absorb odor and other pollution-creating particles. It can also control a lot of gases but are not as effective in the case of formaldehyde, ammonia, and nitrogen oxide.Most air purifiers, nowadays, consist of both pleated filters as well as activated carbon, which can help in better entrapment of the particles in the air. Also, an activated carbon filter gets saturated before a pleated filter.
- UV Lamp:
As the name suggests, the UV lamp is another variation of air filters that uses UV light to purify the air in the room. This kind of purifier emits an invisible light that attacks the pollutants in the air.The UV lamp air purifiers use UV-C band of UV spectrum. This UV band is safe for humans but not for pollutants. Its main task is to eliminate viruses and bacteria inside the room. In the end, you will get a sanitized and clean environment.
- Ionic Air Purifiers:
The Ionic Air Purifiers use a different purification technology. The purifiers emit a cloud of charged ions into the air, which will eventually latch onto the airborne particles. After latching onto the ions, the particles get heavy; then, they fall on the floor.Some of the ionic purifiers come with an electrostatic collection plate. This plate attracts all the fallen particles and eliminates them from the room. This electrostatic process removes particles as small as 0.1 microns from the room.
- Ozone Generators:
The air purifying machines tend to produce ozone that reacts with certain pollutants to change the composition of air. This can lead to dangerous air quality, which can prove to be very hazardous for health. The makers of the O3 generators claim that these devices emit safe levels of ozone. In some cases, ozone can also make Asthma and Bronchitis even worse.
2. CADR Ratings and Room Size
CADR stands for Clean Air Delivery Rate. This is a rating developed by the Association of Home Appliance Manufacturers or AHAM. This is a way to help the consumers, make them able to know how well an air purifier cleans up a room of a specific measurements.
So, it is a standard to learn the effectiveness of the air purifier. The rating is especially important when you are comparing 2 or more devices. But not all the air purifiers come with a CADR rating. If the manufacturers have AHAM independently test the purifier, then the device will have the rating and the certification.
If an air purifier’s CADR rating states that it can purify a room of 300 sq. ft, then it has been texted and verified. It tells you if the device is efficient and if it can get rid of the indoor contaminants.
CADR rating measures 3 different types of air pollutions. It’s just dust, pollen, and tobacco smoke.
ACH stands for Air Changes Per Hour. This rating gets skipped by the users very frequently, as it is difficult to understand. But this is one of the most important ratings that tell you the air purifier’s operation efficiency.
The ACH tells you how many times the purifier can change the air in the room. The common ACH rating will say 4X, 5X, 6X, or anything similar like that on the device. The 4X means that the polluted air inside the specific space will be cleaned 4 times within an hour.
So, if the number is higher, more efficient the purifier. You also need to know the sq. footage. This rating is linked to the size of the space. If the rating states that the purifier can clean the air of a 300sq.ft room 4 times within an hour. Then you have to put the purifier inside a room of a similar to get the maximum out of it. If you place it in a bigger room, the purifier won’t work as efficiently as stated.
4. Placing the Air Purifier
You have to place the air purifiers wisely. If you have a single air purifier, you should place it in a room where you spend most of your time. Generally, it is the bedroom.
These machines are also very heavy. So, they will not be easy to carry frequently. So, place it in the corner of the room where the machine will stay undisturbed and purify the air. Just make sure that nothing blocks its airflow.
5. Noise Levels
While getting an air purifier, you also have to consider the noise. If the purifier performs well but too noisy, then you will have issues. As these devices will run 24X7. So, they should be quiet. Otherwise, you will have clear air, but you won’t be able to sleep.
So, check the specifications before making the purchase. Check the high-speed and low-speed settings.
6. Energy Consumption
Most customers doesn’t even consider energy consumption, but you must. These devices will run 24X7 in the room. And mostly they will run in high-settings. So, check the box the purifier and get one that states energy efficient.
7. Cost of replacement of filters
Filter replacement can be costly. If you get a HEPA purifier, then you have to keep a constant check for the cost of filter replacement. The life of the filter depends on the air quality and the usage. Usually, a HEPA filter can work up to 2000 hours.
So, just don’t get a purifier whose filter replacement will be very costly. If you are running the purifiers all day in the room, then you will have to change the filter at least 3 times a year.
Features of Air-purifiers
We have already discussed the most important aspects of an air purifier; you must keep an eye out for them while making the purchase. But if you want additional features, that will cost you extra money.
So, if you don’t necessarily need them, skip it. But there are a few additional features that are life-saving.
- Pre-Filter: The pre-filter catches the large particles and extends the life of the internal filter or the more expensive filters.
- Digital Controls: The digital controls will allow you to operate the purifier more precisely.
- Adjustable Fan Speed: Air purifiers can have fan sped settings from 2 to 6. It can be low to high and somewhere in between. You don’t require the purifier to run at optimum speed all the time. It also saves energy.
- Filter Replacement Indicators: These are just lights on the purifiers, and they light up when the filter needs replacing. It is a good feature. You don’t have to constantly check the condition of the filter.
Working of Air Purifiers
Air purifiers are some of the best technological devices today. These devices help in cleaning the indoor air quality. Sometimes things add up and could cause harm like pet furs, pollen, or toxic things that needed to be cleaned and purified.
An air purifier works in many different ways depending upon the methods used for cleaning the air quality. One of the most convenient methods is the HEPA (high-efficiency particulate air) filter. Hepa helps to suck the contaminated air into the machine by using an internal fan and pass the same through the filter.
As air goes through the HEPA filter, airborne pollutants get trapped inside the dense material where clean air flows the other side for you to breathe. The HEPA filter is mainly designed to capture the fine particles down to 0.3 micrometers in size, like dust allergies, toxic smoke, mold spores, and bacteria.
