Rabbit Air MinusA2 SPA-700A (covers up to 700 sq. ft.) Ultra Quiet HEPA Air Purifier - Stylish, Efficient and Energy Star® Certified, Wall-Mountable! - White Only

I wanted to post this review mainly because there is no real comparison between Rabbit Air MinusA2 (covers 700 sq. ft.) Ultra-Quiet Air Purifier - 6 Stage Filtration! - built in Mood Light and the Rabbit Air BioGP (model 582A - covers 780 sq. ft.) Ultra-Quiet Air Purifier w/ Germicidal Protection- Low Maintenance - Washable Filters!, Pearl White out there. This is to give you an idea if you're making a choice between the two. [...]

I first purchased the 582A but returned it after a few months of usage due to some minor defect for an exchange with MinusA2 (RabbitAir support was extremely helpful). As a result I have experience with both of these units. The main reason I purchased an Air Purifier was dust elimination and for that particular purpose in mind both these products exceeded my expectations.

Update 4/10/11: I upgraded my review to 5 stars because the optical sensor is a lot of fun. When my cat walks by, it turns purple. When I cut through the ceiling to install a new air conditioning supply register, it turned red for a while. In quiet mode this is just about silent during bed time.

I have both the 700A and 780A series. The simplicity of the design is very attractive, and the electronic controls are top notch. The light sensor is great for the bedroom so it automatically goes into low speed sleep mode. For us, it looks better on the floor than on the wall because of the depth.

I couldn't tell any difference between my 700A and 780A. Out of curiosity I took some scientific measurements of the sound level and power usage between the two models (I work in aerospace, so this was easy).

Basically the ONLY difference between the two is that the 780A fan will blow more air in Turbo mode. The product specs state that the fan spins...Read more

I originally purchased the BigoGS 580 and found the sensors not reliable in my unit. The sensors went from green to red for no apparent reason if I moved it a foot. Instead of getting a replacement I switched to the MinusA2 Spa 700A (toxin remover) due to the 6 stage filtration. I live below two chain smokers and I want to ensure that I have the extra protection. I had the two units for about 2 days to 3 weeks so I can't comment on longevity.

It does a great job removing pollen and odor like the BioGS. It is pretty quiet. I don't even notice it on unless the room is completely silent. I noticed that the silent & quiet modes are more noticeable than the BioGS. I can hear the motor on the MinusA2 whereas on the BioGS I could not unless I was right next to it.

The only drawback that this unit has is if the room is dark, it automatically switches to sleep mode and turn off the sensor light. If you are living near smokers this does not work! Smoke...Read more
