Hepa-Air-filter-purifier After you have done your research and consulted the air quality professionals about which air purifier to buy, you are sure that HEPA air filter purifiers are the right choice. So, you feel ready now to spend a lot of money on the best HEPA air filter purifier you can find.

But wait a minute! The question is are all HEPA air purifiers designed alike? Not by a long run! You need to find out when the HEPA filters don’t equal HEPA performance.

So far you have learnt that that HEPA filters eliminate close to 99.99% of particles in any size range. Its lowest performance is 99.97% efficiency at 0.3-micron particles. It is so in theory, but what about the real world? What about concrete performance? What are the factors that deprive you of the cleanest possible air?

Could you ever imagine that some air purifiers are deliberately designed in such a way to have less efficient features? And you probably wonder why? Because they’re cheap, that’s why!

Yes, high quality air purifiers filters have a very expensive component-the motor. Reducing the cost of the motor, you reduce the price of the air purifier at the same time.

But, if you provide a cheap motor it won’t work continuously against the backpressure of a HEPA filter. It will overheat, burn out and stop working in the end. So, how can you escape that? The companies design air bypassing into the machine. On relieving the pressure the bypassing air can be used in order to cool the cheap motor. Unluckily, the air cleaning efficiency will be lost.

High quality air purifiers have high quality HEPA filters. How do you know how your air purifier works? In a simple way, their producers are always happy to toot their own horn. However, those who use cut-rate HEPA filter purifiers will most likely be silent about the crucial quality matters or otherwise speak some insignificant things.

What are the crucial quality matters for HEPA filters? The first thing on the list is related to the size matters. The bigger they are, the better their functions are. HEPA filters that have bigger surface area get rid of more particulates before they are clogged, thus lasting longer. They can also pass a higher level of air, taking out more particulates each time they pass.

Second, the quality of the HEPA filter material and construction are important. Pleats should be even and kept in place with spacers; otherwise, unevenly spaced pleats may restrict airflow.

Thin paper is the best material for HEPA purifiers, but it can be easily damaged by the pleating process or during installation into the air purifier. High quality air purifiers usually have HEPA filter purifier that have been pleated by a process called “warm rolling”. This is done in order to prevent efficiency robbing cracks to be developed in the pleats.

The producers are really proud of such quality features. Respectable merchants that really understand air purification will grant you the quality. Better to say, the merchants whose only interest is to see you satisfied, won’t sell you anything but air purifiers that truly fulfill your needs.

A Few Examples of Top Quality Air Purifiers

I personally have an air purifier by Allerair. They are really suitable as they match the issues raised above. Another great alternative is IQAir. Actually, they test and certify each air purifier they make for total system efficiency. You are given the certifying document so you know precisely how well your personal air purifier works. I also like NQ Clarifier, Austin Air and a recently arrived Korean brand, Airgle.
