- SMSHERRY M.Verified Buyer1 month agoRated 5 out of 5 starsSimply the BEST
We live in a beautiful place with mountains in our front yard and 3 dirt roads to get to the paved highway. Spring and Fall winds are epic with 45 to 70 mph wind gusts. There is fine powdery dirt in the air. We had two BLUEAIR 211's in our house for 8 years and they handled the tough conditions. I wanted something that had a smaller foot print so tried out another brand that makes vacuum cleaners I like. I bought a large one for the great room and a smaller one for the bedroom. They were DEAD in 3 months, even the one that said "no-change filter." I immediately went back to BLUE AIR and it was like coming home. Immediately the air in the whole house got better and the Blue Signature is perfect for the Great Room and the 311 in the bedroom is the right size. I LOVE BLUEAIR and can say that we have given it the Big Test in a stressful environment and this brand delivers on all of its promises. The more subtle, neutral colors for the pre-filters are much appreciated. The washable pre-filter makes a very big difference. Saturday is wash day and I pop the second pre-filter on while the used one is in the wash.
BUBlueair UK3 weeks agoThank you so much for sharing this incredible experience with your Blue Signature. It means a lot to hear how well it’s performing in such demanding conditions and that it truly feels like coming home. We’re glad the design, washable pre-filters, and performance are making a difference in your space. We appreciate your loyalty and are thrilled to be part of your home.

We really love our blueair air filter. We have a very large open plan kitchen, dining room & lounge. The purifier kicks in any time we are cooking or when we open our doors to the garden and is clearly doing a fantastic job at cleaning our air. It is great that pre-filters and filters are easy to purchase and delivered quickly.
- SBSue B.Verified Buyer12 hours agoRated 4 out of 5 starsWorks too well
Love the design not so much the functioning. Purifier fan runs on high all day if it is set on auto and it can be quite loud. However; it is doing what it is designed to do; eliminating pollutants in the air. Bought the signature air purifier to minimize odor from ciggerette smoke in an open living area while attempting to quit smoking and to keep my house from smelling like an ashtray. So far the purifier is working pretty good and I am looking forward to being smoke free in the next few days and hopefully getting rid of the smoke smell in my house. The signature purifier not only helps eliminate odors but it has also kept the allergens in the air to a minimum as well as the dog dander and dust. My hope is that when the smoke smell has dissipated the purifier will only run as necessary and on a lower fan setting like the blue pure 311i+ does, as the fan speed sound can be rather loud & distracting.
- KSKathleen S.Verified Buyer4 days agoRated 5 out of 5 starsExtra pre filter in blue
I love having the extra pre filter so I can wash one but keep using my blue air. It’s quite nice looking.
- DKDelmas K.Verified Buyer1 week agoRated 5 out of 5 starsWhat a difference clean air makes
We absolutely love our Blue Signature air purifier. The automatic function works mysteriously well. I say mysteriously because it kicks up when it senses the air is dirty and the power just kicks up as needed to clear. Allergies have definitely not been as bad this year as they have been in previous years.
