Can Air Purifiers Remove Asbestos From Air?

Asbestos used to be the biggest indoor pollution threat in a household but not anymore. Still, the thin fiber mineral is not easily detachable and will become airborne when disturbed. It is where an air purifier comes in and prevents you from inhaling it. But how do you know if an air purifier is working? How do to test if there is still asbestos in the air? What happens if you have breathed into the pollutants on more than one occasion? All shall be answered below.
Short answer
Air purifiers can remove asbestos.

 

What Is Asbestos

Asbestos is a natural magnesium silicate mineral fiber that was regularly used as a building material until the 1970s. It is known for its durability, fire retardant, and heat-resistance elements, perfect as an insulation board. Asbestos is part of foam for ceilings, tiles, roofs, pipes, and walls.

In 1973, EPA implemented the Clean Air Act that banned most asbestos spray products due to health hazards. In 1989, the EPA extended the Phase Out Rule act ban. With the new set of rules, EPA will gradually impose a full ban on the manufacturing, processing, and sale of asbestos products. So other than commercial cement boards, Asbestos is rarely seen in residential homes these days.

How Long Does Asbestos Stay In The Air

Asbestos will linger in the air between 48-72 hours, even when there is no air movement. Because Asbestos can easily be friable when disturbed (sanding, cutting, or drilling), it will break down into small fibers. The tiny fibers are very lightweight and become airborne with little push. If there is continuous airflow like a fan or air conditioner, asbestos fibers will stay afloat indefinitely unless there is an air purifier pulling them down.

How To Test For Asbestos In The Air

You could hire a professional to do the inspection through the OSHA Inspection Method. It is easy but will cost you between $200-500. Instead, just purchase an asbestos home test kit that you can do yourself within a couple of minutes. First, pick the spot you want to do the testing. Then draw an air sample into the canister or tube from the test kit. Make sure to draw the amount exactly as instructed in the manual. Finally, mail back the samples in the original box. We recommend Nirtue Labs home test kit as it accurate and will only cost you only around $25 including lab test. You should receive the result after 5 working days with instructions on what to do next.

Do Air Purifiers Get Rid of Asbestos?

Only an air purifier with a True HEPA filter will remove Asbestos. On average, asbestos fibers and particles range from 0.7 to 90 microns. This fits HEPA filter criteria as it can capture particles as small as 0.3 microns with 99.97% efficiency. If the air cleaner uses an inferior HEPA-type filter, it would still catch most fibers. Regardless of which type of HEPA filter, the air purifier must have airflow output to cover an entire room. Otherwise, there would not be enough airflow force to pull down the very lightweight fibers.

How to Prevent Asbestos Exposure In The Home

We all know HEPA air purifiers work, but there are other equally effective ways of protecting yourself from Asbestos. First and foremost, if you are staying in an old home dated before the 1970s, get it to check for asbestos contamination. If there is no leakage issue, you are left with 2 options. A) Do not disturb the asbestos materials by sealing them tight and avoiding DIY renovation. Or B) Get it sorted for good by hiring a certified asbestos remover and contractor to remodel the entire house. Option B is lengthy, costly, and painful, but it will give you peace of mind knowing your home is safe and toxic-free.

Other no-brainer actions include tossing away old items sprayed with asbestos paint. There is no smoking indoors as the chemical fumes do not mix well with asbestos fiber. Lastly, keep your home well-ventilated to reduce the concentration level of Asbestos.

There are still an estimated 3500 different types of products containing asbestos. Most of these items have either obsolete, limited to commercial use, or have a very low concentration level. But what happens if one breathes into asbestos once or twice? Probably nothing, as if the concentration level of asbestos in the air is low. Nonetheless, keep an eye out for the first sign of asbestos poisoning. You might experience:

  • Tightness in chest
  • Shortness of breath
  • Dry cough
  • Loss of appetite
  • Chest pain
  • Pleural thicken
  • Finger clubbing (enlarged fingertips)
  • Nail deformities

Most asbestos exposure would take between 10-20 years to developed Asbestosis. Asbestosis is a chronic lung disease caused by inhaling asbestos fibers. If the situation remains, Mesotheliomas would also occur between 20-50 years after prolonged exposure. Mesothelioma is a type of cancer that develops from the thin layer of tissue from internal organs like the lungs or chest.
