"We have had this for almost 3 weeks，This air purifier is great from the look, to the functionality. i put the air purifier for my baby's room, because i think babies are born with an immature immune system and babies breathe at more rapid rate than adults. i want to make sure my baby's room stays as healthy as possible. it is so important to have in the home.so that's why i bought a air purifier for my baby's room.!! And so far, it works great. This purifying system is quiet, efficient, keeping the air circulated and clean in the bedroom at night. somethimes the baby's diapers smell terrible, but i turned it on and I went to check on it. Absolutely no smell in the room! ~~~" - Sophie

Testimonial

"So we have now owend our BreatheSmart for about 2 months. My wife and I couldn't be happier. We live in a high rise building and have about 1200sq ft. We have placed the unit in such a way that it can pull the air from both large rooms at the same time. We noticed after only a few days how the amount of dust on the furniture diminished . My wife and I also had been having nose congestion and blowing our noses to no end for a few months, we think because of the dust. After about a week, no more sneezing, and after about 3 weeks, no more congestion. We have the unit running 24hours a day. I do notice in the early morning hours that the status light does go to blue, lowest setting, so I know that the sensor is definitely working. You do need to make sure to check and clean the PREFILTER about every 10 days , depending upon your situation. I just take a Dustbuster type vacuum and clean it in about 3 minutes. This is a MUST. I also invested in the better filter to capture more particles like mold, just to be sure. No, we don't have mold, already tested for that. It was worth it to me. After spending this much for the system, another $50 for a better filter was a no-brainer. Don't skimp on the heart of the system, the filter. No, its not overly noisy. If you want it to work, then it has to make some noise. If it really bothers you then take it off of automatic and drop the speed down a notch. I give it a 5 star rating and would recommend it to anyone in the same situation." - DelMarDad

Testimonial

"I did ALOT of research before purchasing an air purifier. There are several models for larger rooms that rate higher-check out airpurifierratings.org. But I am tremendously pleased with the germ guardian. It's so nice to be able to breathe again! I've had the unit approximately 3 weeks. LOVE it!! Also; I did purchase a roomba iRobot vacuum.

Testimonial

"I will start by saying that I have never purchased an air purifier before. I wish I would have sooner. I am incredibly impressed with this purifier. I’ve had it on for a month solid because I’m living in new house with some indoor air issues, mild and lots of dust. I have an allergy to both and my daughter had been coughing since we moved in. We also had a wicked stink in the house. Could not figure out where it was coming from. We plugged with in and within a few hours you could notice the air was cleaner. It smelled nice inside and felt lighter. It’s hard to describe. Within a week the pre filter was so coated with dust and crap I was in shock! I included a photo of the predicted after a week use. It is simple, works well and I have had zero issues so far. It looks nice as well. I would highly recommend it." - A. Holmquist

Testimonial

"I bought the Rabbit Air MinusA2 based on extensive research on my part as to the best air purifier for cigarette smoke. I have only had it a week but I must say that it does the job. My husband who is a non smoker says he does not smell any smoke whatsoever. It seems to be removing cooking odors as well. I previously had an Idlys air purifier which was quite good but the filters were costly and had to be changed about every 4 months. I replaced it with the new Idlys model which was supposed to be more powerful and it was terrible. It was only effective on the very highest speed and it was so loud that it made my ears ring. The auto mode didn't work at all. I returned it to the place of purchase and decided to buy the Rabbit. The Rabbit is very quiet even on the highest speed. It is very effective on removing smoke odors. There are 4 different filters (germ defense, pet allergy, toxin absorber, odor remover) to choose from so you can customize your Rabbit to your needs. This model covers up to 700 sq ft. The room I have it in is about 400 sq ft. It is a bit pricey at $500. but it works so I think it is worth it. The filters cost about $85 per year. I have only had it a week so time will tell if they last that long or not. If they do that is quite a savings compared to the Idlys which cost me about $250. per year. This model can also be mounted on the wall if you like. I did not mount it on the wall. It really doesn't take up much space and I wanted the flexibility to move it around if I wanted." - Patty

Testimonial

"I have struggled most of my life with asthma and allergies and have always had an air purifier in my bedroom. I’ve been through several other air purifier brands and to be honest they have all worked about the same….I get relief (but not 100%). A friend recommended Blueair to me earlier this year and I have delayed in purchasing one. I am now happy that I waited as this product was only recently released with wifi.
The instructions for connecting the air purifier to wifi are made clear, but I did give a quick call to the customer service team just to make sure I was setting everything up correctly (they were very helpful). Now that this purifier is set up and running in my room I am thrilled as to how it is working. I can absolutely tell the difference between this product and others I have had in the past. I think my favorite part of this air purifier is the ability to control via my phone. The app is very user-friendly and it allows me to access, power, and control the air purifier remotely.
Overall I am very happy with this purchase. I like the look, the feel, and the way it is running. It was hard for me at first to drop $400 on an air purifier—however now that it is running, (and I am feeling healthier and sleeping better) I am happy with the investment. You can’t place a cost too high on your health!! I would recommend this unit to anyone looking to purchase an air purifier." - Nathan

Testimonial

"Prior to April, I owned an air cleaner with an ozone generator. It not only did a "meh" job, but destroyed itself after 5 months. Then I ordered this one. 8 months in, and I can report that for its price range, this one is a solid winner. Beyond a quick vacuuming of the HEPA filter, and washing the pre-filter, it's still doing its job brilliantly........on the filter set which came with it. That's a very good thing, because replacement filters are quite expensive, but if this original set actually functions well the entire year, as advertised, I can live with the expense. Unobtrusive. Effective. Relatively quiet." - Mary

Testimonial

"I received the Rabbit Air unit 2 weeks ago and so far it is working well. The automatic function detects when we are cooking or kicking up dust in any way and ramps up immediately. The air coming out of the unit smells clean (I was worried it would have a plastic smell). I have two birds and the bird dust gets on everything. I have this unit sitting a few feet from the cages and it has significantly cut down on the amount of bird dust on the top of furniture. I wish it was priced a little cheaper, as I'd like to get another to cover our large downstairs area." - Kimberly

Testimonial

"We have had the Biota Bot for a little over a week now. I'm not really one to write reviews but thought it so worth it to give feedback on this product. I can definitely notice a difference when we walk in to the house. We have a Great Dane and 2 cats, so keeping the house smelling fresh has always been somewhat of a challenge. It is really impressive that when I walk in the house, the first smell that comes to me now- is my oil infuser. It's such a great feeling to come home to! It also helps with clearing the air after cooking meals, which we do quite often at home. In Auto mode, the sensor came on almost immediately when I was cleaning the kitchen. Love the design and highly recommend this product." - Caleb
