How does a HEPA air filter work?


There are numerous air purifiers on the market. But the way HEPA air filter, (High-Efficiency Particulate Air) work is actually quite simple.

These purifiers are comprised of a filter, motor/fan and housing and these are the three standard components.

The filter itself is a mechanical air filter which works by forcing air through a fine mesh.

The mesh traps such harmful particles as pollen, pet dander, pet hair, mold spores, dust mites, tobacco smoke. But it also traps allergens and other solid particles. Thus it truly can be the best air purifier for allergies.

How long does a HEPA air filter last?

Of course, after a certain amount of time, these filters require cleaning. The best ones can be cleaned using a vacuum cleaner.

However, it is an investment as the filters will also need to be replaced after about 12 months (in most cases). They will eventually become clogged beyond the help of a vacuum.  The airflow gets reduced, meaning you aren’t getting the same clean and safe air you did originally.

Still, given that it provides you with this kind of protection for twelve months, it is safe to say that it is worth the investment for a HEPA air filter.

What is the best HEPA air purifier to buy?


The market is overwhelmed with different types of air filters and purifiers.

They range from HEPA air filter, ionic and electrostatic ones, to ozone generators, air scrubbers, and UV air purifiers. Many claim to be the best air purifier for allergies.

These all come with their set of advantages and disadvantages. But hands down the HEPA air filter purifier the best on the market.

Ozone generators have actually been removed from the market when it was found that ozone is incredibly bad for the lungs.

Ionic and electrostatic ones have permanent filters with lower efficiency. Aside from that, ionic ones tend to also create ozone.

UV filters are commonly used in places affected by water to prevent the creation of mold, so they aren’t technically air purifiers as much as lamps that sterilize a water-affected area.

This is exactly why almost all commercial air purifiers now use a HEPA air filter. HEPA air filter reviews section, we’ll look specifically at the best of the best.

Making the final selection


Now you are aware that HEPA air filter purifiers aren’t only the most efficient but also the safest ones on the market. So it is time to narrow down the search and pick the right one for you.

First of all, eliminate all the purifiers that are labeled as ‘HEPA-type’ or ‘HEPA-like’. These vague specifications should serve as a red flag.

Chose the one that specifically states the ability to efficiently remove 99+% airborne pollutant particles. Numbers like these matter. But there is another clue that will reveal whether a purifier is for you – the size of the particles it can remove.

The best and most innovative ones can get rid of impurities as small as 0,1 microns, which is impressive, and are virtually noiseless. You can’t be the best air purifier for allergies without truly filtering out these tiny particles.

Choosing the perfect partner in protecting your home has never been easier. With innovations in the field, it is now simple to eliminate the good from the not so good and make the right decision with ease.
