Rabbit Air Minusa2 Air Purifier Review

Yes it will-but…. HEPA filter standard is .3 micron particles, cigarette smoke is in the .01 to 1 micron size. But wait….. (none of what follows is specific to this particular unit or brand)
https://www.engineeringtoolbox.com/particle-sizes-d_934.html I also saw a distribution chart that indicated most cigarette smoke was about .1-.15 microns. This is why the absolute answer is ‘No it won’t,’ the ‘holes’ in HEPA filters are too big. It will however, capture a lot of particles because particles hitting any part of the filter will stick–so it will help a lot. (Think of 1″ balls hitting a sticky wall covered in 2″ holes, and ten more walls just like it: a lot of those ping pong balls are going to be stuck right next to holes they could’ve passed through) Also this unit has an ion generator, this charges every particle in the air, which is then attracted to a collecting plate. These generators make ozone which is bad for your lungs and recommended against. However (again), I intentionally bought an electrostatic generator only air filter when I stayed a couple of nights in the apartment of a chain smoker. It was incredibly effective, but I would never use it long term. I also saw tests in a consumer products article in the New York Times that said 90% of sub .3 micron sized particles were trapped by HEPA filters (I’m a bit suspicious of the article….but I think this result is reasonable. I live where there are a lot of wild fires, and someone used to smoke near my house nearly every morning and the air movement brought the smoke in. I learned often after the smoke stopped it was in my house for days after, but if I vacuumed (I have a HEPA vacuum) that eliminated it. If you don’t have a HEPA vacuum, what I used to do for my photo darkroom is to get a second hose, attach it to the vac’s exhaust and run it outside.. The typical vacuum cleaner does a great job of grinding small dust up into even smaller dust and pushing it out the exhaust hole. If you buy this unit I would recommend never using the electrostatic setting except for those rare times someone smokes inside the house. I just had the idea that if you use a HEPA unit after a ‘smoker’ incident, and you have that vacuum cleaner set-up, vacuum the outside of the HEPA filter after the ‘incident’, I’ve vacuumed the outside of my HEPA units’ carbon first filter regularly, and the HEPA filter inside my vacuum cleaner I will also vacuum off if my paper vac-bag has leaked. And N95 face masks (get the ones with the small exhaust valve) over your face work as well as any of this stuff. I wore one yesterday when smoke from the wild fires blew in my direction. Of course close doors and windows. The most effective way to deal with a smoker is to get as far away from them as possible, with weed smokers? call them up when they are good and stoned (and paranoid) and ask if their weed has pesticide in it because you can smell pesticide…. Hope this helps. 

I have very bad allergies and I live a 500 Sq. Ft Efficiency unit.
I wanted the unit the clear the air of cooking smells and allergens.
I called Rabbit Air posed the question and the bottom line is there is very little difference between the filter combinations they sell.
I bought the:
Rabbit Air MinusA2 (model SPA-700A covers 700 sq. ft.) Ultra-Quiet Air Purifier – Stylish, Efficient and Energy Star® Certified, Wall-Mountable!, White, Toxin Absorber unit and love it.
The nice thing about these units is that if you find that the filters are not enough for your allergies you can purchase and replace the filter with the one that is best of allergies. I have not found that to be necessary. The unit has 6 filters and there is only one filter difference to go to the high allergy model

I have not noticed any major difference, having 3 dogs and 2 cats. We initially bought the unit for our office, but I tried it in my house for a week when we realized the unit simply could not perform as an effective smoke eater (as advertised). It performed a tiny bit better in a less harsh environment, but again the results were negligible. Honestly got better results opening windows, and that doesn’t cost $600 (+$100/yr for filters)

If the negative ion generator is on, it DOES produce ozone. The levels are below those required by the California Air Resources Board. However, recent information indicates that no level of ozone is safe. So I personally wouldn’t use the ion generator.
