  • Great product!

    The best thing about this air purifier is not needing to replace expensive filters often. When the indicator light shows that the filters need cleaning, you can vacuum the inside of the air purifier. The unit is very quiet. We use it in lower level of our house where the air circulation is not that great. Since there is a guest room down there, it has been perfect to "clean" the air for guests. I have moved it upstairs when the pollen season is at its peak to clean the air upstairs as well. My daughter borrowed this unit and was amazed by how much it reduced the settled dust on her furniture. Costs more than most air purifiers, but worth it.

  • Not Ultra Quiet. Horrible chatter/clicking sound.

    Other reviewers mentioned this could happen and it appears the motor loosens up or something after a bit and just is pretty bad. I also bought another Rabbit Purifier for more money. Not listed as ultra quiet and it's not. But I wanted this one because of the extra features work well with keeping our pet fur down and not so air born. Anyway set it up and was super happy with it. Compared to the other model bought at the same time it was quite and though not silent it was something I could live with. I have sensitive ears due to menieres and so relaxed. Until three days later it started to chatter. And my husband checked out the works and concluded it's in the motor's timing and nothing we could do or shim or fix...the chatter is worse on lower and actually cycles from not to high the higher fan setting you select. So not for our bedroom. Not for the other two places we could substitute it to sit either. This item is quite big and not easily set on a narrow shelf due to the feet. If it sat on solid all the way across you might get away with it on a shelf about it's width but the feet make it too unsteady though that is why they are there to stablize it. On a table or floor setting it seems to work best. I like the easy front access to the filters to vacuum frequently. And I haven't had to wash any of the washable filters as of yet. We have a large house with open ceilings from 16-25 feet high. But we have down stairs on the main floor three air cleaners going. I can't recommend to anyone however due to the loud noise the clattering makes. Along with other reviewers also mentioning similar problems after a small bit of time the manufacturer must be aware of this problem. Perhaps they will fix it. Because the other features and filters are just fine.

  • Odor Sensor Quit Within 4 Weeks of Use

    Was concerned about the noise when purchasing an air purifier but the reviews posted were positive and I can attest to it as well. In the lowest mode you really cannot hear it. I cover the front because I like sleeping in the dark. This air purifier seemed to make a difference in allergy symptoms in both me and my cat. Around a month into use, the odor sensor failed to function. Resetting the baseline did not work so called RabbitAir directly to get their guidance. That was a fiasco. After numerous calls and troubleshooting they said they were shipping me a new unit. A supervisor called back an hour later to say they could not ship me a new unit as the order wasn't processed directly through them as it should have been. Overstock.com is supposed to give them the order information directly and they ship to the customer. This wasn't the case in my order and caused much confusion on their part. Needless to say, I called Overstock.com and the customer service representative was kind enough to handle my return. The identical unit is out of stock so I purchased an upgraded RabbitAir model and am hoping that this one will stand the test of time.

  • Excellent Product, Great Price

    I had an air purifier for a few years now and it didn't seem to do the job. My wife smokes in side and we have four small dogs. So we battle urine, smoke, and dog smell. After two days of use this machine took the smell away. My wife is amazed at the fact that when she lights a cigarette it detects the smell/smoke and kicks into a higher speed. This machine is extremely quiet on the highest setting, which is one of the best features. Last purifier I owned, the low speed wasn't near as quiet as this machine on high speed. This is one of my favorite purchases I have ever made and once I can get more money together, I definitely want another for the second floor.

    REad many reviewers who complained about other products being very noisy. Within one day our musty smell was GONE. Easy to clean filter. Also nice looking, with long cord to put or move to a convenient spot.

  • Breathe Easier

    Whisper quiet is true on Auto setting... Other fan speeds are noticeable, but not annoying ... At night, portability is wonderful, so I move it to bedroom and kick it on HIGH, cause I have carpet in there ... When Allergy season began, I suffered tremendously, before my unit arrived... Does it remove every particle of pollen or dust?... NO, nothing will, be realistic .... But there is great improvement in sneezing & watery eyes with filtering ... Unit is attractive, light weight portability, easy-to-read digital control face ... Filters include 3 in box: big particle screen (will catch pet hair) washable.... HEPA (for pollens) lasts 18 months, charcoal (odors) lasts 3 years ... To keep sensor clean, wipe with dry qtip occasionally ...easy! ... I plan to purchase another unit for the other half the house, silver

  • I love it

    I bought one and liked it so much I bought a second. It sit in a large living room/dinning room area and this morning I did a little wall sanding to touch up a wall 20 feet away. within minutes the Rabbit Air sensed the dust and increased speed to remove it then later dropped back down to low. It was set on automatic. I never saw the dust and did not know it was there but this air purifier did. Sanded another spot later and it did the same thing. The first one was in my office and I started brushing my long haired cat. That one did the same thing picking up the cat dander from the brushing. Great product. On auto low. which is where both usually run you cannot even hear them unless standing right by them. Very quiet.
