Testimonial

"My first impression was euphoria. My nose and sinuses cleared instantly. Breathing through my nose was noticibly easier and I slept better the first night. My bedroom no longer smells stale or like dog. I feel so much better about my space i now keep it cleaner. My baby sleeps longer before waking up. All of this in a weeks time. I have not used the ionizer function at all.
I wish I had purchased the 1100 sqft instead of the 800 because on the automatic setting it runs the fan at a 3 or 4 most of the time. The bigger unit would be more efficient for my large bedroom." - Theaznal

Testimonial

"I am allergic to every airborne allergen except dogs and pine trees. Over several years, I have purchased 8 or 9 Air Purifiers and/or Ionizers. This is my 3rd Rabbit Air Purifier. It arrived yesterday, four days before the promised delivery date. I love Rabbit Air because their air purifiers are quiet, efficient, and easily maintained. This one has 3 features that were new to me. One was an adjustment to sense pollen in the air (plus another adjustment to make it more sensitive). Another was the automatic "Sleep" function: When it gets dark - and it got dark in my living room early last night - the "mood light" goes out and the fan slows down. I was surprised when it happened and called Rabbit Air customer service. A clear-speaking American answered the phone and assured me everything was working as programmed. She even encouraged me to go to the machine and put my hand over it to prove that it was still working. The third feature, one that I thought was frivolous and stupid, is that Mood Light. It is the band of light you see in the picture. It is solid blue if the Air Purifier is sensing dirty air. It changes color if it is sensing pollen. I have been a meditator for 40 years. I find this Mood Light to be calming and it helps me focus when beginning to meditate.
As with all Rabbit Air products, the instructions are clear and easy to understand." - Charles

Testimonial

"We just moved into a brand new home in October and have been monitoring our air quality using a Foobot. Since purchasing the iAdaptAir L, our average daily readings have improved significantly (see below).

- Global Pollution Index Score - Before = 28 (good) Now = 12 (great)
- Volatile Compounds - Before = 301 ppm (fair) Now = 148 ppm (great)
- Fine Particulate Matter - Before = 13 ug/m3 (good) Now = 5 ug/m3 (great)
- Carbon Dioxide - Before = 1,074 ppm (good) Now = 574 ppm (great)

We have definitely noticed an improvement in the freshness of our air and will be purchasing another iAdaptAir for our finished basement soon." - Eileen

4. Rabbit Air Starry Night HEPA Air Purifiers

Features & Benefits

• Over 33+ Positive Reviews
• At Rabbit Air, we believe you shouldn't have to sacrifice style for health. We created the Artists Series featuring images by Gustav Klimt, Katsushika Hokusai and original designs by Rabbit Air's creative team, to offer our customers a sophisticated answer to stale air. Dutch post-impressionist artist Vincent Van Gogh sold only one painting in his lifetime, yet his The Starry Night is one of the most famous works of art in the world. Thick, swirling brushstrokes give motion to a sky of deep blues, greens, and yellows over a dark church spire and a quiet town. Painted in 1889, the masterpiece evokes Van Gogh's homeland, the Netherlands. A cloudless night reveals a mosaic of stars.

Testimonial

"I am really impressed with this product. We have a home that has no duct work at all as we have hot water boiler with radiators. Having two dogs in the house is an issue because of the smell as well as the hair and dust. This product really reduced the amount of dust in the house and also improved the smell of the house. I also like the feature to change the filtering for pollen. The filter set that we got was the pet one and I feel it's working really well for us. I also like the ability to turn the negative ion setting on or off. The filter hanging on the wall really does look like a piece of art and when people see it for first time they are really impressed that it's actually an air filter. I was really concerned about the amount of noise that it would make and when I have the fan on auto you can't hear it at all." - slg

Testimonial

"I purchased this purifier to replace a very large and very loud Honeywell unit. While I suspect the throughput of the Honeywell was greater, the dramatic decrease in noise is a worthy trade off. The Conway's replacement filters are also significantly cheaper. I would purchase again.
The addition of a few carefully placed vinyl stickers also creates the worlds largest iPod Nano (see pic)" - Stig

Testimonial

"I wasn't sure what to expect with this air purifier. What I did not expect is how profoundly quiet the unit is when running! I can barely hear it run even when I stand next to it. I didn't think I would notice any change in the room air, but both my husband an I did after just one day. We both thought the air seemed fresher, lighter and cleaner. It was nice that this unit came with 10 additional disposable filters. The filters are very thin, but have a narrow peel off sticker boarder to keep them securely in place. The other filters are washable. The unit will clean 300sq ft and the manual states that air purifying is greatly enhanced by keeping doors and windows closed-duh! The manual also stated to just turn the unit on and it would sense the air and run accordingly. I haven't touched the unit after at least a week. It just cycles on and off intermittently. I am very happy with having the chance to try this air purifier and intend to keep using it!" - S. Lipson

Testimonial

"I am blown away by how quiet this air purifier is! I am mad that I didn't find this product before I ordered my germ guardian model last year. This winix is super quiet, even on the full speed. I will update with pictures in a few months after use. So far I am very impressed with the quality of this machine. It seems like it is moving a large amount of air, and is virtually silent. I have it in my kitchen and my fridge is louder than this air purifier!" - Evan

Testimonial

"I purchased the Pure Zone Air Purifier about 4 weeks ago. I have waited to review the product so that I can give an experienced review. I travel a lot and noticed that over the last few months, when I came home, I coughed horribly in the mornings and several times throughout the day. I was okay when I was away from home, so I decided to try the system based upon the Amazon reviews. After receiving the unit, I quickly set it up...running it continuously. I was so pleased, noticing that my coughing/congestion was significantly less each day. My husband doesn’t travel with me, and his coughing/congestion was much worse than mine; in fact, he has been to doctors off and on over the last couple of years and taken many lung tests to no avail. We concluded that it was probably side effects from his medications, because our home is very clean and less than 20 years old (so hopefully no mold or anything). I was so impressed with my results that I purchased one for my husband's main living area, also. I have seen a remarkable difference in both of our situations. I don't usually give reviews, but this is amazing. I wish I would have done this two years ago.
Pros: enjoying healthy air, quick setup, quiet system that can run continuously, long-lasting filter" - Pam

Testimonial

"I have now used this Air purifier for about a week and can say that it's a fine product which has reduced the dust on the furniture quiet a bit. We are using this in the carpeted rooms and with the heavy traffic in these rooms, we used to notice a lot of carpet lint on the tv and other furniture. But that has been considerably reduced from the time we have started using this product. It is also very quiet and the white noise is minimal. It blends perfectly with the white furniture we have in the room. We are planning to order another one for our kids room. Highly recommended!!!" - PAG1976
