• Easy to use: just plug in the air purifier and it's ready to use
• Low cost to run: energy star rated and only requires as much energy as a single light bulb: only 35 watts on low to 90 (model 501) or 120 (model 601) watts on high
• Durable steel construction: the grills and powder-coated steel exterior are easy to wipe clean, and won't pick up grime or oily stains the way plastics can, and they do not off-gas
• SurroundAir™ technology diffuses clean air gently: instead of discharging a windy stream of filtered air, the Blueair diffuses air gently through an area six times greater than the average air cleaner; operating on its lowest setting Blueair produces virtually no noticeable draft, while still providing an exceptional air exchange rate
• Choice of filters:
  • Standard HEPASilent particle & gas filters: HEPA-type polypropylene particle filters with a carbon impregnated pad that has a very limited amount of activated carbon in it, offering minimal removal of gases, odors and chemicals
  • SmokeStop filters: HEPA-type polypropylene particle filters with 5.3 lbs. of activated coconut shell carbon impregnated with Potassium Iodide (KI), Phosphoric acid (H3PO4), and Potassium Hydroxide (KOH) to control gases, odors, and VOCs
• Environmentally safe filter media: Blueair replaces standard triclosan-coated paper or glass filter fibers, which can harm the environment when released into the waste stream, with safer, nontoxic polypropylene. This revolutionary filter media is one of the least harmful plastics, producing only carbon dioxide and water as it decomposes - used filters are 100% recyclable, and release no toxins into landfills or the air
• Filters resist contamination: because polypropylene is waterproof, Blueair filters naturally resist contamination from bacteria, viruses and mold, without chemical additives or weekly washes
• Easy to change filters: simply open the lid, lift out the old filters and drop the new ones in - no screws, hooks or tools needed; Filters should be changed every 6 months
• Long warranty: Blueair air purifiers are durable and carry a 10-year limited warranty

• The 501's performance has earned it the Best of Class ranking in independent AHAM testing of Clean Air Delivery Rate
• The 601 beat out the 501 with an excellent CADR score near the top of the scale with a 450 score for pollen, 400 for dust, and 438 for smoke
• Unique filtration technology combines electrostatic and HEPA-like technology for a performance beyond almost every residential HEPA filter with the ability to filter 99.7% of particles down to .1 micron
• Safe use of electrostatic technology without producing ozone or off-gassing
• Less filter restriction allows the Blueair to push more air volume through its filters than any other top HEPA machine, while operating at a reduced noise level
• Blueairs high air flow is great for quick cleaning and the lower, almost silent speeds provide the ideal operation level for continuous day or night use when you are in a room
• Polypropylene filter material is water-repellent and naturally retards mold and mildew growth eliminating the need for chemical-bases bacteria or mold inhibitors that are used in most residential glass fiber HEPA filters
• The SmokeStop filters feature 5.3 lbs. of impregnated activated carbon providing sufficient removal of gases, odors, and VOCs
• With a contemporary sleek look it is the winner of several European design awards and the Blueair 501 is featured in a permanent exhibit at the National Museum in Stockholm
• The award winning design of the Blueair 601 is not only stylish and very efficient, it also allows for easy filter changes that take less than a minute of your time
• This air purifier is energy star rated and low cost to run - costs about the same to run 35-90 or 120 watt bulb depending on model and fan setting
• Extended Warranty: as long as your replace your filter with Blueair replacement filters every 6 months, your air purifier is covered against manufacturer's defects for a full 10 years

• The biggest minus we could find is the units lack of a pre-filter: Pre-filters help prevent dust build-up on the fan and inside the unit which are hard areas to clean; a pre filter also helps extend the life of the particle filter by trapping the large particles and pet hair that quickly dirty a filter
• Replacement filters are expensive and require semi-annual replacement which is twice as often as many HEPA filters that usually have a life span of 1 year. However, because these filters are made of polypropylene they can be gently vacuumed to extend their useful life lasting for 1 year or more depending on use. (Please Note: the 6 month lifespan is based on running the air purifier on high speed, 24/7)
• No filter change indicator leaves it up to you to check the filters to see if they are dirty
