Top 10 Best Air Purifiers List

1) Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier

Fun facts: Here is the list of Best Air Purifiers for consumers in 2018, and if Breathe Quality has to pick one to be the winner of them all, we think we will stick with this guy: Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier.

And why we consider it the best air purifier system for home available?

Rabbit Air is one leader in air purifier market, starting from 2004. Their MinusA2 is the latest True HEPA Filter air purifier product to compete in the air purifier market. To perfect this product, Rabbit Air created a Six-stage purification & deodorization to make the cleanest, freshest air possible in the world (notice that typical air purifier only consists of 2 to a maximum of 4 filter for air purifying). Let’s dive into:

  1. Pre-filter – The polluted air must pass through a pre-filter, there it will capture all large particles, along with dust mites and some of pet hair.
  2. Medium Filter – Traps large pollen, pet dander, mold and dust particles that is small enough to bypass the Pre-filter.
  3. Advanced BioGS HEPA Filter – It is a True HEPA Filter that captures 99.97% of all allergens, virus particles, pollen, mold and fungi particles down to 0.3 microns. Rabbit Air advances their air filter process, therefore prolong optimal filter efficiency and filter life of their HEPA Filter.
  4. Activated Carbon Filter – Eliminates odors, smokes and chemical vapors.
  5. Customized Filter – Let’s you customize the product and choose from a variety of customized filters including Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber.
  6. Ion Generator – allows the particles to get trapped more easily by your air purifier’s filters, or to settle onto the floor where they can be picked up by your vacuum instead of accidentally inhaled. Can be switched on/off.

best air purifiers

So basically MinusA2 is a combination of almost all of the popular air filter types. Thanks to the reduction of common allergens from the Pre-filter and Medium filter, The Advanced BioGS HEPA filter can last at least 3 years, profitably reduce the cost of HEPA Filter replacement after 6 months to 1 year like normal.

While including an Ion Generator, due to the fact that Ionizer Filter’s downside is irritating asthma and respiratory issues, MinusA2 brings an on/off control for this function. So if you are allergic to the ion, you can turn it off.

Many customers love MinusA2 because they can customize the front panel in both color and/or design. Many different artistic design choices, from Vincent Van Gogh, Claude Monet, Katsushika Hokusai to original designs by Rabbit Air’s creative team, are available to suit your taste. Moreover, you can hang this air purifier to your wall, making it a perfect art.

For variety of options, MinusA2 comes with three editions. The first is SPA-700A, which covers up to 700 sq ft (around 65 sq m). The bigger (covers up to 815 sq ft) has two editions: SPA-780A (with no wifi connection) and SPA-780N (wifi enabled). With Wifi enabled, the SPA-780N can be controlled via an iOS application.

Choosing the right filter types

The classic Air purifier comes with a HEPA filter. Some may have other filters for specific needs, here are the terminology and definitions:

Pre-filter – An essential feature of air purifiers that use a HEPA style filter. The pre-filter captures the large dust and pet dander to help prolong the life time of the main filter. Most pre-filters are washable and reusable and last a lifetime.

True HEPA Filter – This is the highest standard air filter you can get for a best air purifier. In order to carry this label, the filter must meet strict regulations set by the United States Department of Energy (DOE) and capture at least 99.97% of particles as small as 0.3 microns. A true HEPA filter needs to be replaced after 6 months to 1 year, and you should use the suitable replacement for your air purifiers.

Activated Carbon (or Charcoal) Filter – This filter can absorb odorous particles and gases. That’s why it can remove the smells produced by smoke, pets, cooking, chemicals, etc.

Ionic Filter (or Ionizer) – This filter emits negative ions to charge small particles like dust, pollen and bacteria and collect them into a plate.

UV-C Light – The Ultra Violet light destroy bacteria and virus by sterilizing them. The UV-C Light (UV Light type C) is harmless to human.

Advanced BioGS HEPA Filter – A technology from Rabbit Air, to help prolong the life of the main True HEPA filter.

Permanent HEPA Filter – A technology from Hamilton Beach, to make their HEPA-type filter be cleaned by vacuum, therefore you don’t need to replace their HEPA filter.

HEPA-type Filter – This filter is a lower quality version of a True HEPA filter and doesn’t meet the standards set in place by the U.S. DOE mentioned above.

Choosing the right size air purifier
