Especially if you have asbestos insulation in your house, investing in an air purifier is essential. Most people worldwide avoid asbestos linings because of their harmful side effects.

However, if you still have this material in your house and you want to purify your air of its microparticles, then you are at the right place. Keep reading to know the best HEPA air purifier for asbestos and what you need to look for when shopping for it.

What is Asbestos?

Asbestos is a naturally occurring mineral used for insulation in housing and different machines. It is a fibrous silicate used for thermal and electrical insulation.

Even though this material was a major part of the construction, it is now banned in Canada, the UK, Australia, and 28 countries of the European Union. Despite that, it is still used in many parts of the world, including the US.

Exposure to asbestos fibers can be hazardous to health, especially when inhaled for an extended period. It can cause respiratory diseases like mesothelioma, asbestosis, and lung cancer. So, if you have this mineral around you, getting an air purifier is necessary.

Will HEPA Air Filter Catch Asbestos?

The high-efficiency particulate absorbing (HEPA) air filter is popular for its strong filtration properties. Because of its strong filtration system, these air purifiers are commonly used in schools, hospitals, offices, and houses. It can filter out even the most stubborn and difficult impurities from the air, like asbestos.

Asbestos particles have the size of 0.7 to 90 microns that can infest our lungs and cause severe diseases. Therefore, getting a filter to remove particles less than 0.7 microns to properly clean your air is important.

Most traditional air purifiers can remove dust and smell from the air but cannot remove bacteria, viruses, and asbestos fibers as small as 0.3 microns. This is why we suggest using a HEPA air filter. It can remove particles as small as 0.3 microns from the air. This way, you can breathe in the cleanest air possible.

If you don’t know whether the air around you contains asbestos particles, you can use an asbestos testing kit. Once you have identified the impurities in your air, it is time to get a high-quality HEPA filter. The best part is that it can also protect you from airborne viruses, allergens, and dust.

What to Look for in an Air Purifier Asbestos?

If you are looking for the best air purifier for asbestos, there are a few things that you need to consider:

Filtration Technology

It is important to know which filtration technology the purifier is offering. There are several main kinds of filters available in the market: pleated filter, electrostatic, UV light filter, washable, HEPA, etc.

The HEPA filter is ideal for removing asbestos particles from the air. Since it can filter particles as small as 0.3 microns, it is perfect for preventing any damage caused by asbestos in the air.


The coverage of an air purifier is mentioned in the form of CADR. For example, a CADR of 200 for asbestos means the purifier can filter out asbestos particles and provide fresh air at 200 cubic feet per minute.

You need to put most air purifiers near the source of asbestos. However, these days, many strong air purifiers are available in the market to catch asbestos particles from all over the house.


Air purifiers come with several fans that pull the air inside to pass it through the filters. Unfortunately, these fans can make a constant noise which can disturb the users.

However, some purifiers come with a relatively silent fan. These fans either make no sound at all or make a soft humming noise that is barely noticeable. An air purifier with less noise is the ideal option to go for, especially if you have to keep it in your bedroom.

You can also get portable air purifiers to transfer them to different rooms. If you have a small and lightweight air purifier, you can place it wherever you are working for a relaxing and healthy experience.

Filter Lifetime

Lastly, check the lifetime of the filter of your air purifier. If you are getting a HEPA filter, you need to change it every ten years. This is a fairly long lifetime considering the efficiency of the filter.

This filter will keep dust, bacteria, asbestos particles, viruses, and allergens away from you.
