Best Replacement Air Purifier Filters in India in 2020

A filter is one of the most important parts of an air purifier that helps in filtering out dust particles and debris. As the air passes through the filter, all the dust, allergens, hair, pet dander, and other particles get trapped to the filter and start accumulating over it till it gets saturated.

Once the filter is saturated completely, it starts releasing the pollutants that is trapped on the surface back to the air. Hence, it is very important to clean and replace the filter regularly. We have explained the best way to clean the filters in the buying guide.

Most of the air filters require frequent replacement of the filter. The frequency at which it needs to be replaced depends on the type of filter that you have.

A general replacement schedule for filters is:

  • HEPA Filters: Should be replaced every 12 to 18 months
  • Carbon Filters: Should be replaced every 6 to 8 months
  • Pre-Filters: Should be cleaned properly once in a month and replaced when damaged
  • Permanent Filters: Should be cleaned every 3 months and replaced when it is damaged

Note: this schedule might vary depending on the air quality, water quality, frequency at which you use the air purifier.

Do All Filters Need To Be Replaced?

To know if the filter requires replacement or not, you must determine the type of filter used in the purifier. Some air purifiers come with a permanent or long-term washable filter. In these models, you will not have to worry about buying the replacement filter every now and then.

However, you should still clean these filters on a regular basis to maintain their effectiveness. You can either wash these filters or clean them using a vacuum cleaner regularly (once in 3 months, depending on the usage).

Even if the air purifier comes with either a washable, disposable, or permanent type filter, all the filters have a limited lifespan. They need to be either replaced or cleaned regularly as they require proper maintenance.

Some models of air purifiers notify you whenever it is time to clean the filter. However, one thing that you must be aware of is even the permanent filters need replacement over a period of time to run efficiently.

How Often Should You Change The Filter In The Air Purifier?

It is very important for you to know how to clean and maintain the air purifier at your home. The frequency at which you should replace the filter depends on multiple factors. Some of the factors are as follows:

1. Default Indoor Air Quality:

If the indoor air is very dirty, the purifier’s filter will reach its maximum capacity too early. For instance, if your house is located along a busy road, it might be exposed to the pollutants and smoke that is emitted by cars or other vehicles. These pollutants can shorten the lifespan of the filter. If you have pets at your home or if you smoke inside the house, these factors can also shorten the lifespan of the filter.

2. Frequency of Usage:

If you use the air purifier throughout the day, it might need extra maintenance when compared to the units that are being used for only a few hours a day.

3. Water Quality:

The quality of the water at your house also has an impact on the lifespan of the washable filters. Tap water is generally rich in mineral deposits and if you clean the filter using tap water, it can reduce the life of the filter. These mineral deposits can cause harm to the filter resulting in unwanted clogging.

4. Filter Type:

Some types of filters need to be replaced quite frequently than the others. You should clean the pre-filters regularly at least once in a month. While some purifiers use carbon filters to attract dust and allergens and neutralize odor, others use HEPA technology to trap even the tiniest allergens present in the air. For such filters, it might be difficult to understand what is the best time to clean them.

Thus, most of the purifiers these days come with special filter check indicators. It allows the users to know that it’s time to clean or replace the filter. However, you might not find this feature in all the models. In this case, you might have to rely on some other signs to figure out whether the filter needs replacement or not.

Signs That Show That The Filter Needs To Be Replaced or Changed

If the air purifier at your home does not come with a filter change indicator, these signs can help you determine if you should change the filter or not.

  • You can see noticeable dust or dirt build-up coming out of the filter, in a distinct gray color.
  • The house might seem dirtier than usual.
  • You will notice a huge amount of pet dander in the air.
  • You might notice increasing symptoms of asthma and allergy.
  • There will be a different odor or smoke in the air.

In this case, your intuition can be very helpful. It is always best to clean or replace the filter as soon as you notice dirt or deposit build-up in the air as it can hamper the overall performance of the air purifier.

General Filter Replacement Schedule:

Here is a list of general replacement schedules for different types of filters. This schedule can give you a brief idea of how frequently you should replace the filter

If the manufacturer fails to provide correct information on the replacement cycle, you can check the type of filter used in the air purifier and follow this general guide to determine the lifespan of the filter.

  • HEPA Filters: Should be replaced every 12 to 18 months
  • Carbon Filters: Should be replaced every 6 to 8 months
  • Pre-Filters: Should be cleaned properly once in a month and replaced when damaged
  • Permanent Filters: Should be cleaned every 3 months and replaced when it is damaged

Benefits of Changing Air Purifier Filters:

If you wish to maintain the efficiency of the air purifier, you should clean and change the filter at regular intervals. Some of the benefits of replacing the filters are:

  • Using the air purifier with a clogged filter can slow down the entire cleaning process of the unit, making it hard for the purifier to finish its job. Changing the filters regularly increases the lifespan of the purifier.
  • If not cleaned on time, you will be adding the collected dust and other debris from the filter back to the air.
  • If the filters are clogged completely, the air purifier stops working completely.

Tips For Extending The Lifespan of Air Purifier Filters:

Some tips that can be helpful to you in the long run are:

  • Clean the purifier and the air inlets properly using a soft and dry microfiber cloth properly. This will prevent the debris from accumulating inside the filter.
  • Keep the area surrounding the air purifier clean to avoid unnecessary air clean-ups.
  • Place the purifier in an open area to promote free inflow and outflow of air.
  • Rather than using brooms to clean the floor, use mops. Using both dry and wet mops for cleaning can reduce the amount of dust particles flowing in the air significantly.
  • Use the purifier in a closed space otherwise the filter can get worn out quickly.
  • Use good quality dusting clothes so that most of the pollutants are trapped and removed effectively.

How to Clean a HEPA Filter?

HEPA filters are available in disposable, washable, and permanent forms. It is easy to maintain washable or permanent filters. They can cut down on the replacement cost drastically. Disposable filters, on the other hand, need to be replaced after some time.

You should first check whether the filter that you have is a washable filter or a permanent filter. You should only dry-clean the permanent filters either using a brush or a vacuum cleaner. You shouldn’t wash it as it can get damaged.

You can rinse the washable filters in water and get rid of accumulated dirt.

Before trying to clean the HEPA filter, we suggest you to go through the manual properly so that you don’t end up damaging it.

We have explained how to wash permanent and washable filters properly in detail below.

How to Clean a Permanent HEPA Filter?

Here’s how you can clean the permanent filter at home without damaging it:

1. Remove Filters:

Turn off the purifier and unplug so that it is safe to remove the filter. After turning the unit off, move it to a place where you get easy access to all the sides of the purifier.

Most models of the air purifiers come with a back cover that can be opened. It allows you to open and access the filters easily. If you are not sure how to remove the filter, check the manual, and follow the directions.

Before removing the filters out of the purifier, make sure that you cover the floor using plastic sheets. You can even take the purifier out to clean. As HEPA and pre-filters can hold a significant amount of dust, it is better you clean it outside so that the dirt does not fall on the ground.

2. Clean the Pre-Filters:

The permanent HEPA filters usually come along with a pre-filter and an activated carbon filter. You should remove and clean these filters too. Before washing any of these filters, you should check the manual properly.

You can rinse the pre-filter using water by simply placing it under the tap until you see clean water flowing through it. If it is a fine wire filter, be gentle while cleaning it and use a soft-bristled brush. You can even use a damp sponge to wipe either side of the filter.

While cleaning foam or carbon pre-filters, towel dry properly and let it dry for 24 hours.

You should vacuum clean the activated carbon filter gently and remove the dirt and dust. Don’t wash these filters. Simply clean both sides using vacuum in horizontal motions. If you feel that the carbon filter has absorbed a high amount of odor, you can even leave it under direct sunlight for around 1-2 hours.

3. Vacuum the HEPA Filter:

To vacuum the HEPA filter, you can simply use a vacuum cleaner. The handheld vacuum cleaners are easy to use and clean.

Using a nozzle or soft brush attachment to the vacuum cleaner helps in cleaning the filter easily. It also prevents any damage caused due to vacuum. Use the vacuum in horizontal motions so that you get rid of the dirt and dust completely.

Be gentle while vacuum cleaning the filter. Don’t be hard while pushing the attachment into the filter. Rather than doing this, you can set the vacuum to a stronger suction. This will help in removing dirt that is embedded deeply.

4. Reassemble:

Once you are done cleaning the pre-filters and the permanent HEPA filter, you can start assembling it back. Place the HEPA filter first, followed by the activated charcoal and the pre-filter at the end. If you are not sure if you placed it properly or not, check the manual for instructions.

Quick Tip: If you have washed the pre-filters and kept it for drying, cover the HEPA filter using plastic and store it somewhere safe so that it remains clean.

How to Clean a Washable HEPA Filter?

Before even trying to wash the HEPA filter, go through the manual properly and make sure that it is washable. Some manufacturers even provide the washing guide in the manual.

Some brands suggest you to simply rinse the filter in the water whereas some brands allow you to wash it using soapy water. Some washable HEPA filters are even dishwasher-safe.

If you didn’t get a manual or if you have misplaced it, you can check online for the instructions on the manufacturer’s website. Just check with the correct model number.

1. Remove and Clean Pre-Filters:

You can follow the same procedures as mentioned above in how to clean a permanent HEPA filter.

2. Rinse:

After cleaning and drying the pre-filters, you can start cleaning the HEPA filter. You can clean smaller filters by rinsing under tap water in the bathroom or kitchen. For larger filters, you might have to rinse it using a water pipe or garden hose or under the shower.

If you have flat filters, wash both sides of the filter and get rid of dirt and other contaminants. If the purifier has cylindrical filters, rinse it only on the outside. Try to avoid getting the water inside the cylinder.

While rinsing the filter, try to avoid rinsing it in high pressure as it can cause damage to the filter. Turn on the tap at a low or medium flow and wipe the filter using your fingers. It will help in loosening the dirt.

Some manufacturers recommend washing the filter with soapy water. Some brands even suggest washing the filter with either cold or lukewarm water. You can check the manual for any such instructions.

3. Dry:

You should let the washable HEPA filter air dry completely before you start reinstalling it. After washing the filter, shake it off to get rid of the excess water. Keep it against a wall so that it gets dried using fresh air from all the sides.

Note:

Never use a hairdryer or blow dryer to speed up the drying process. Doing this can damage the filter and is against the warranty policies too. Always let the HEPA filter air dry for some time.

4. Reassemble:

After all the filters are dry completely, you can start reinstalling them. Install the HEPA filter first followed by the rest of them. If you are not sure of the order, check the manual.

Frequently Asked Questions

1. Is it important to dry a washable filter after washing it?

Yes. You should let all the filters dry completely before installing them back to the purifier. If you don’t do this, mold will start forming and growing over it. Due to this, the purifier will emit foul odors.

If you don’t clean and maintain the filter properly, a layer of dust and grime will start building up on the filter. This can damage the filter completely and quickly. It also promotes the growth of mold over the filter. It spreads bacteria and you might soon start noticing a lot of dust and pet dander in the air. Thus, you should always maintain the air purifier properly. You must always turn off the purifier while cleaning it. Clean it regularly to keep your house free from dirt and other microbes.
