Good Air Purifiers for Allergies Collect Particulates with HEPA Filters

Updated on January 15, 2014

What are the Best Air Purifiers for Allergies?

There are some people who doubt the power of air filters when it comes to removing airborne allergens. Logically speaking, it really is quite baffling to think that a small machine could eliminate nearly all allergens floating around in the air that you breathe. But while air filters can be quite compact, that doesn't mean that they can't protect you from sneezing and wheezing fits.

High Efficiency Particulate Air filters or HEPA filters appeared sometime in the 1940s. It was then registered as a trademark when it was introduced to the commercial market. HEPA's claim to fame is that it can remove almost 99.97% of air particulates like dust, smoke, mold, and other allergens as small as 0.3 microns. It is worth noting that there are several generic HEPA filters out in the market. Consumers should check the efficiency rating of the air filter they are interested in and compare it with the true HEPA standard.

When it comes to choosing the right air filter for your needs, there are certain things to consider. An obvious concern is figuring out what substances the filter can and can't remove from the air. A buyer should also find out how large of a room the machine can handle. A very important thing to check is the machine's clean air delivery rate or the amount of clean air that comes from the machine.

Whirlpool Whispure Air Purifier AP51030K

Whirpool's AP51030K model has a three-stage filter system. It starts with the pre-filter, goes on to the carbon filter, and ends at a true HEPA filter.

The pre-filter acts as a barrier for larger particles that are sucked in by the device. The second stage in the process is the carbon filter and is meant to eliminate odors. Finally, the HEPA filter gets its turn which, as stated, eliminates close to 100% of the allergens and miniscule particles in the air.

The fan has 4 speeds and includes a sleep and turbo mode.
