A HEPA air purifier is a filter used for cleaning air. HEPA stands for "High Efficiency Particulate Arrestor Air filter." This air filter is used to improve the quality of air and clean equipment such as vacuum cleaners and other similar types of appliances. Mostly, HEPA air purifiers can screen different airborne particles, like asbestos measuring around 0.3 microns. The reason why many experts note the use of HEPA air purifiers is that they are so efficient. The efficiency rating of a standard HEPA air purifier is around 99.97%. HEPA purifiers are deigned to filter some of the hardest particles to screen. These particles include smoke, animal dander, dust, dust mites, and asbestos residue.
HEPA air purifiers have been useful for many different companies, such as air pharmaceutical sites and areas that have had toxic spills. Especially for buildings, HEPA air purifiers are mainly used to remove and filter asbestos. The following section discusses how these air purifiers remove asbestos and other particles from specific locations.
Process of Filtering
The HEPA air purifiers have specially designed air filters that are capable of trapping different allergens and particles, such as asbestos. The screen-like construction of the filters absorbs or traps the particles while letting clean air pass through. Many professionals note that in order for an area to be completely asbestos-free, it’s important to use the air purifier a number of times. All asbestos particles that may have eluded the filters during the first try will definitely be trapped the second time. The more the air purifier is used, the better the quality of the air. There should be a higher exchange rate of air to ensure that air quality is at its best.
However, it is important to note that one HEPA air purifier can clean only one place at a time. You cannot simply assume that all connected rooms will be cleaned just because the door is opened. For example, a HEPA air purifier inside a bedroom can only clean the air within that room. The living room and other areas should be purified at a different time since they are not cleaned at the same time as the bedroom. There is a limit to the scope of each HEPA air purifier.
There are good HEPA air purifiers known for their filtering efficiency. If you really want to get rid of all the asbestos remnants, using these brands may be a good idea. Two good brands that you can take a look at are EZ Air and Austin Air.
Both HEPA air purifiers can provide around 15 air exchanges every hour. For a 1.000 square footarea, these two air purifiers can provide up to eight exchanges. Be careful in choosing your air purifier, as some only provide up to two air exchanges per hour.
