The Rabbit Air MinusA2 is a six-stage HEPA air purifier for bedrooms, living rooms and home offices, rated to 815 sq ft at two air changes per hour or 408 sq ft at the four changes per hour Rabbit Air recommends for allergy and asthma sufferers. It runs at 25.6 dBA on its lowest of five speeds and 51.3 dBA on its highest, and it can sit on the floor or mount high on a wall. Its distinguishing feature is a customized fourth-stage filter you pick: Odor Remover, Toxin Absorber, Pet Allergy or Germ Defense. The SPA-780N adds WiFi, the Rabbit Air app and Alexa control; the SPA-780A ships with a remote. Against larger units like Rabbit Air's own A3 it trades capacity for quiet, compact coverage, and owners rate it highly for quiet operation and build.

Owners rate the MinusA2 highly, with quiet operation and solid build the most common praise. Many say it helps with allergies and pet dander in bedrooms. Complaints center on filter replacement cost and the limited capacity for larger or smokier rooms.
The MinusA2 is a quiet HEPA air purifier for bedrooms, living rooms and home offices. It covers up to 815 sq ft for normal residential use at 2 air changes per hour. For allergy and asthma use, at 4 air changes per hour, it covers up to 408 sq ft. Both figures are based on an 8 ft ceiling and the highest fan speed.
It cleans the air in 6 stages: a washable pre-filter, a medium filter, a BioGS HEPA filter, a customized filter you choose, an activated carbon filter and a negative ion generator. BioGS HEPA removes over 99.99% of ultrafine 0.01-micron particles (chamber test at the highest fan speed, including natural particle decay). The filter media is treated to inhibit odor-causing mold on the filter itself. The customized filter is Odor Remover, Toxin Absorber, Pet Allergy or Germ Defense.
Particle, odor and light sensors work with Auto mode, which adjusts the fan speed. In a dark room the light sensor switches the unit to sleep lighting, and a mood light is optional. You can mount it high on a wall or set it on the floor near a desk or bed. Two versions are available: the SPA-780A comes with a remote, and the SPA-780N adds WiFi, the Rabbit Air app and Alexa voice control.
