If your idea of the best air purifier is one that covers large areas, the Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier makes a good argument for the best large room air purifier. It handles 815 square feet with ease. It also has six stages of air filtration, one of which is an alternative to True HEPA filters.

Why We Like It – Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier

The Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier rocks the boat by introducing not three, but six stages of filtration, including modern features like Auto Mode, Sleep Mode, and Wi-Fi connectability.

  • 6-stage filtration system
  • Germ Defense customized filter targets bacteria
  • Wi-Fi capabilities
  • Expensive

Power & Speed

There’s some really good power behind this machine. Crank it to the highest fan speeds and it can achieve 200+ CFM, which isn’t the fastest nor exceptionally powerful, but still good nonetheless. It isn’t entirely concerned with speed as it is with quality.


To put that power into perspective, RabbitAir Minusa2 Air Purifiers can handle purifying air in a room as big as 815 square with incredible ease. More importantly, it has four air changes per hour, meaning you have a batch of new air every 15 minutes. However, the Coway Airmega 400 covers 1560 square feet, almost twice as much.


Compared to the Alen BreatheSmart Classic Large Room Air Purifier, the purifier Rabbit Air Minusa2 SPA-780N has three more filters for particles to pass through. In other words: 6-stage air purification HEPA filtration. For clean air quality, the pre filter traps large particles first, then the medium filter handles pet allergens, mold, and anything too small for the pre-filter. The BioGS HEPA filter does away with virus particles, allergens, mold, and 99.97% of other nasty particles as small as 0.3 microns. The fourth filter can be Germ Defense, Toxin Absorber, Odor Remover, or other customizable filters offered by Rabbit Air, though the activated carbon filter does handle most harmful oors. The ion generator actually traps particles or lets them fall to the floor for the vacuum to handle.


Another reason Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier has a higher price tag is through its use of higher quality materials. It’s one sturdy piece of equipment. You’ll understand once you realize its maximum weight is under 20 lbs. So if you mount it, don’t forget to use anchors.


There’s so much to like about the Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier. Its unique 6-stage filtration system is by far its greatest asset for cleaning the indoor air. It comes with a light sensor, mood lighting, and an indicator light for reminding you of replacements. Unfortunately, these air purifier types and filter replacements tend to be expensive, and it is. If you aren’t ready to spend that kind of money, and need something smaller, the Levoit Core 300 is $100.

Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier Wrap Up

The biggest thing holding the Rabbit Air Minusa2 Ultra Quiet HEPA Air Purifier back is its price. However, in the end its price is warranted in the right hands. This is the kind of powerful air purifier you get when you’ve already settled with their purpose. It’s hard to pass on so many filters in one sleek, compact machine.
