Rabbit Air MinusA2 Features and Specifications

The MinusA2 has a smart light sensor that will automatically transition to sleep mode in dim lights, and will resume in a more active state when light levels increases. This helps with energy saving, assuming that there isn’t someone around the room to purify the air.

MinusA2 SPA-700A, with the highest setting can filter the air twice an hour and with a CADR of 171 pollen, 173 dust, 166 smoke.

The purifier can make some noise when at higher speed levels, however, the noise does smooth out and will eventually become white noise to your ears. The noise level can range from 20.8 to 45.6 dBA, and potentially higher for different models (25.6 to 51.4 dBa for the SPA-780A or SPA-780N).

Difference between the SPA-700A, SPA-780A, and SPA-780N

The SPA-700, which is the one that is currently reviewed, is the smaller of the two. The SPA-780A/N, both can purify the air up to 815 sq. ft., while SPA-700 can only go up to 700 sq. ft. And filters smaller amounts than the SPA-780.

The difference of the SPA-780N is the WIFI capability. With the WIFI connection, you’ll be able to control the device anywhere, which is an added feature, because you’ll be able to see the quality of the air in real time and can turn on the filtration before going home.

At the time of this writing, there’s only a Rabbit Air App for iOS devices.

Filters for the MinusA2

You’ll be able to choose four different filters, each dedicated for different use cases:

  • Germ Defense Filter – This allows the air purifier to trap and reduce any airborne bacteria, mold spores and particles that carry viruses.
  • Pet Allergy Filter – It traps and reduces pet dander and pet allergens, perfect for people who are highly allergic to pets.
  • Toxin Absorber Filter – Traps and reduces volatile organic compounds (VOCs) and other chemicals
  • Odor Remover Filter – traps and reduces odors from cigars, cigarettes, cooking, mildew, and pets.

It may be a good idea to get all filters and have one filter on standby to switch them out depending on your environmental air quality.

The MinusA2 goes through six steps of filtration before it gets recycled back into your environment, giving you quality air. It is built economically, lasting up to two years when you’re operating the unit for 12 hours a day.
