Best Overall Air Purifier

We consider this the best home air purifier system available due to its wide range of features and air cleaning power. The Rabbit Air MinusA2 air purifier offers a remarkable 6-stage air purification process that creates the cleanest, freshest air possible. This includes:

  1. Pre-filter – To capture the largest particles and prolongs the life of the other filters.
  2. Medium Filter – Traps large allergens and dust particles.
  3. BioGS HEPA Filter – Extra-long life version of a True HEPA Filter that captures the tiniest of all allergens, dust, pollen, and mold particles (99.97% down to 0.3 microns). Lasts up to 3 years which is 3 times as long as any other filter on the market.
  4. Activated Carbon Filter – Eliminates household odors from pets and cooking and chemical vapors.
  5. Customized Filter – You can customize this filter based on your specific needs. Choose between enhanced germ defense, toxin absorption, pet allergies or odor elimination.
  6. Ion Generator – Creates an ionic field to neutralize airborne contaminants without producing ozone.

Room size coverage is also excellent at 700 square feet, which covers most areas in the home. If you can afford it, however, we highly suggest that you invest in the best air purifying machine.
