Rabbit Air BioGS 2.0 Ultra Quiet HEPA Air Purifier (SPA-550A) by Rabbit Air

I was skeptical about spending this much on an air filter when I don't have bad allergies or something that would make this a necessity, but I am definitely not regretting this purchase. I have 2 cats in a 2 bed/2 bath apartment and I keep the litter boxes in one of the bathrooms. I am a litter cleaning nazi so it doesn't smell but it would get super dusty in there. Also note I live in Colorado, perhaps one of the dustiest states in the union. I had a cheap filter I bought at Target for awhile but that thing was insanely loud and didn't do a fabulous job. Enter the RabbitAir - amazing! It is so quiet on the lower settings, and the higher settings are a nice white noise if you like that sort of thing. During the day I keep it on the auto setting, and it does an amazing job of detecting when a kitty has used the litter or i have cleaned the boxes - it ratchets up to the highest setting for a few minutes and totally eliminates the dust. I take it off the auto setting at night though because I can see it from my bed - the change in noise doesn't bother me, it's that the lights go on every time it changes settings which is annoying. So I put the fan on medium at night and it is a lovely white noise. I would highly recommend this product if dust is a problem for you.

I have two units, one operating all the time, and they are fabulous. They adjust speed to conditions but mostly run really, really quietly because of a more expensive motor and great design. The filters are easy to clean and install and are absolutely not a rip off in pricing. The design is an asset to any room too. Mine are well over a year old and performing perfectly. What a great product, and remember that indoor air quality is often worse than outdoor quality. You probably need one of these.

I have a 520 sqft condo and this model is perfect for it. The setup is simple and well explained. $100CAD for a filter can be seen as steep, but there are two of them and last about 1.5/2 years.. I added a small Houzetek in a small cabinet, strategic place where most of the neighbors' kitchen odors come from, and the two makes a good pair; I have no more rancid garlic / burnt odor from my neighbors since. Additionally to that, the air inside is better. For sure it is a certain amount to pay, about $500 is nothing to laugh at, but you have what you paid for and the peace of mind with it. The unit is silent most of the time, and fully automated (my big tower PC make more noise than it). It is always possible to manually override it and boost the fan at the max when needed.

It's been 2 months since I bought the BioGS 2.0, and I'm really happy with it so far. I live in a townhouse that is over 100 years old and could use a dusting twice a day, plus I am asthmatic who lives with a husky-shepherd mutt that I'm allergic to. I really needed something to clear up the air in my bedroom, which is a mere 87sq ft, connected to another storage room of equal size (totaling 174sq ft). - Very good sensors. If I make my bed and throw the blanket in the air, I guess there must be dust because the BioGS will kick up a level and get to work. Same if cooking smells waft by, so odor sensor works extremely well too. My room wasn't bad with odor prior to this so I can't say if it's truly great at removing smells. One should probably just clean their room and linens if something stinks in the bedroom. Pros: - Quiet on low settings, which it's on most of the time when you leave it on auto. It's easy to forget it's on. - Aesthetically beautiful. The white and the curves looks very modern and sleek; the way the functions glow and fade off is also pretty. - Well made design from a utilitarian standpoint. It is simple and easy to open, easy to clean, easy to control. Even the controller is simple and attractive. I just take off the front of the case, wipe down the dust with a microfiber cloth, take out the first two filters (prefilter & charcoal) and vacuum them. - Works well!! I have nothing but rave things to say about its effects. I no longer wake up with itchy eyes, sneezing, and coughing...which used to be a daily occurrence. You take a deep breath in my bedroom and the air is just...clean! I have kept up with taking off the cover and dusting the inside and vacuuming (on the weakest power setting) the prefilter and the charcoal filter. It's CRAZY to see all the dust stuck on the prefilter, that would otherwise be bothering my lungs. Cons: - On high setting, can be very loud, and kinda breezy. Still, that function usually does not last too long before it brings itself back down to a lower setting. - It's kind of big, but you can say this about MOST air purifiers in existence. My room is 87sq ft, all I can fit is a dresser, full-sized bed, and a doggy bed on the floor. I did not have 2ft clearance as some other reviewers suggest from the wall, however a representative of Rabbit Air that I spoke to online said it was fine to put it closer to the wall...so long as nothing is blocking its intake and outtake. So I put it on my dresser, problem solved! It's a bit big, but its functionality is very much worth it for me. None of those cons are enough to deduct a star, because it just works so well and is so well designed for me to maintain it. I have not had to replace any filters yet. At the 2 month mark, everything looks just as good as new once I vacuumed it. I expect keeping up with monthly dusting will prolong the life of my current set of filters. The high pricetag of this unit made me nervous but I am beyond pleased with it, it's nice to have a machine that just WORKS and is attractive; other air purifiers I researched were more iffy on quality control among units. So I think I paid for some peace of mind.

I bought one of these filter systems about five years ago. It has performed well. I started having some breathing issues last year and I bought three more of them and have installed in different rooms. There are a lot of products out there and sometimes you just don't who to trust. I went back to Rabbit Air because they have a proven track record at my house.
