The Blueair 403 continues to deliver outstanding performance that has withstood the test of time. Using patented HEPASilent technology, it captures 99.97% of the tiniest particles, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles. The Blueair 403 is designed for maximum performance in mid-size rooms. Our Swedish design is not only attractive but built to last. We are known for our durable construction that is made of galvanized steel and is powder coated for durability and environmental protection that produces no chemical off gassing. The air purifier housing is easy to clean, and won't pick up grime and oily stains the way plastic may. Air is drawn into the unit via an ultra-quiet fan. Airborne particles pass through an ion chamber and are charged to ensure that they adhere effortlessly to Blueair’s progressive three-stage filter. Clean air that is free of impurities is then recalculated into the room.

Rated 5.0 out of 5.0 by Does the job We have had our Blueair almost two years and we're very pleased with it. My husband smokes occasionally and I wanted to be sure we didn't have a smokey odor build up in the living room. The Blueair 403 is quiet and efficient. It is on low all day and if I notice any odors, I turn it up to high when we go to bed. When the filter needs changing, I can tell right away - the fresh odor that I usually encounter in the living room is gone, time to change. The filter does not last quite six months for us, we have a high volume ceiling that may come into play there but it is still more than worth it to us for the great job it does. June 27, 2014
Rated 5.0 out of 5.0 by Great for older houses/allergies My husband and daughter have allergies/congestion almost year-round. We moved into a house built in the '80s, and the quality of the air was noticeably worse than in our previous residence due to older ventilation system/dustiness plus some kind of older place smell... We decided that 2 of 403 series air filters would be a good investment for our family as we really value our health. We had these air filters for over 6 months now. I have noticed significant improvements in my husband's and daughter's congestion and allergy incidents. Best part - there is noticeably less dust in the house and the "old house" smell has been gone. I would recommend this product. June 21, 2014
Rated 5.0 out of 5.0 by Happy breather! I have been using a Blueair filter in our daughter's bedroom for several years and are extremely happy with the clean, dust-free air, the quiet motor, and the ease with which she is able to breath. Her allergies are now under control with the help of this filter, and her medications. It is most important that her bedroom be as allergen-free as possible, so that she is able to get the best possible rest and be ready to engage in life fully by day. The filter helps to make this possible, even in NYC air. Thank you! June 21, 2014
Rated 5.0 out of 5.0 by This product is fantastic I got this product because I am an asthmatic and have several allergy issues. Because of the purifier, I have not had any allergic reactions or asthma attacks. I have finally found a product that will help me have a good nights sleep without being woken up by an asthma attack or allergies. This product also works in silence, making it even easier to sleep. Overall this is a great product, and I would highly recommend it. March 9, 2013
Rated 5.0 out of 5.0 by Quiet, Effective and Great Quality I have two of these units for going on 4 years. I put an addition on the house and added a wood pellet stove. Love the heat that produces in the winter, but not the dust from the pellets and ash. The 403 unit keeps the air (and room) much cleaner. The other unit is in the bedroom and helps with allergies. Both are quiet as well as very durable and well made. June 19, 2014
Rated 5.0 out of 5.0 by No more dust particles I have used the 403 Blueair with the HEPA particle filter for almost 6 months to avoid asthma resulting from dust mites. The filter has been very effective in my bedroom. My cleaning lady told me she doesn't have to dust anymore in the bedroom! When I phoned Blueair for a replacement filter, the agent was very nice and helpful - Thank you. June 19, 2014

Rated 5.0 out of 5.0 by Effective and quiet air filter! We love this air filter. We bought our first one about 5 years ago due to dust mite allergies. It made such a difference, we bought another one for our kids bedroom. It has been easy to use and maintain. I am so happy we found blueair. I would definitely recommend this product. June 21, 2014
