The Blueair Blue Signature is a stylish air purifier that offers multiple air quality readings and does an excellent job of eliminating harmful pollutants in your home.
Designed to blend seamlessly with your home’s decor, the Blueair Blue Signature ($449.99) is an attractive smart air purifier that utilizes multi-stage filtration to keep the air in your home clean and safe. It works seamlessly with the Alexa and Google smart home platforms, provides multiple air quality readings, and can even double as a side table. While its replacement filters are on the pricey side, it offered similar performance to air purifiers that cost hundreds more in our testing. It’s an elegant and effective option for scrubbing large rooms of harmful airborne particles, earning it our Editors’ Choice award for smart air purifiers.Design: A Squat Cylinder That Can Double as a Table
The Blue Signature is a sleek, cylindrical purifier that measures 17.2 by 15.5 by 15.5 inches (HWD) and weighs 13.2 pounds. It utilizes a wraparound filter protected by a washable cloth pre-filter layer. The filters uses Blueair’s seven-stage HEPASilent filtration technology, which employs electrostatic charges to attract pollutants and capture volatile organic compounds (VOCs), as well as other harmful chemicals. Additionally, carbon, enzyme, and mineral elements absorb and break down gases and odors before recirculating the cleansed air back into the room. The filters are designed to capture at least 99.97% of airborne pollutants down to 0.1 microns in size.
Several other top-rated air purifiers also use 360-degree filters, including the Editors’ Choice-winning Dyson Hot+Cool Formaldehyde HP09 ($849.99) and the Dyson Big+Quiet Formaldehyde BP03 ($1,099.99). The Blue Signature’s cylindrical filter is rated to last up to one year before replacement is necessary. A replacement filter will set you back $99.99. That’s more expensive than the Dyson HP09 filter, which costs $79.99 and is also expected to last up to one year. The Dyson BP03 filter is the longest-lasting, with a five-year lifespan, but is also the most expensive to replace at $169.99.
Because the top of the Blue Signature purifier is flat, it can be used as a tabletop to hold a plant or books, but if you really want this device to blend in as a furnishing, you can order a $79.99 wooden base with legs that adds another 4 inches to the overall height and makes the purifier look like a real end table. Other accessories include pre-filter coverings in various colors ($24.99 each) and a chrome base ring ($99.
