Blueair 301

• Easy to use: Simply plug in the air purifier and it's ready to use
• Low cost to run: The Blueair is very energy efficient since it uses no more energy than a light bulb: only 20 watts on low to 120 watts on high
• 3 fan speeds: Choose from HEPASilent™ for nighttime use, moderate for daytime use, or maximum operations for fast initial cleaning or very polluted air
• Durable steel construction: The external parts have been powder coated for durability and environmental protection that produces no chemical off gassing; air purifier housing is easy to wipe clean, and won't pick up grime and oily stains the way plastics can.
• Side to side airflow: Blueair air purifiers are designed with side-to-side airflow, which allows placing the unit against the wall to save space.
• SurroundAir™ technology diffuses clean air gently: Instead of discharging a windy stream of filtered air, the Blueair 301 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.
• 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 and low maintenance filters and exterior: When the filter needs to be replaced (twice yearly), just open the lid, lift out the old filter and slide in the new one. No screws, hooks or tools and less than one minute of your time is required.
• 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.
• Safety switch: Automatically turns power off when air purifier door opens for filter change or any other reason
• Long warranty: Blueair air purifiers are durable and carry a 10-year limited warranty

How Blueair 301 air purifiers work:

Pluses:

• Takes up little floor space: With a small footprint, this air purifier is a good design for smaller areas
• Very quiet: On the low and medium speeds, the air purifier is extremely quiet, so one can keep it running all night in the bedroom
• Cleans air effectively: The Blueair 301 will clean an average size room very effectively, and this is the only air purifier we have found which gives more than an adequate number of air changes per hour on low fan speeds
• Easy filter changes: The access to get inside the unit is very easy. You simply pull on the right side of the front and the panel opens up. Inside you simply slide the filter out to replace it. The filter replacement takes seconds and requires no tools.
• Sleek design: With a contemporary shape, putty colored steel exterior and distinctive blue power light, it can blend in with most decor
• Durable metal construction: All major parts are made from high-quality galvanized steel, not plastic
• Extended warranty: As long as the Blueair filters are changed every 6 months, the air purifier is covered against manufacturer's defects for a full 10 years

Minuses:

• Expensive filter maintenance: You must replace the filters twice a year to qualify for the 10 year extended warranty. This is the longest warranty in the industry today which shows that Blueair stands behind their products.
• Does not have a pre-filter: In order to extend the life of the particle filter, a prefilter would have been a good addition to this air purifier so it could catch larger particles first
• Not a true hepa: According to the manufacturer, the combined effectiveness of their HEPASilent™ media and the internal ionizer brings the effectiveness of the filtration up to true hepa standards of 99.97%. Given that the term HEPA is given to the efficiency of the main filter alone, it cannot be termed true HEPA.
• No filter change indicator: Since the life of any filter will vary enormously according to the conditions you place it under, an indicator light allow one to get the most out of the filter before replacing it
• No gas filtration for gases and odors: The technology used in the filter has a very limited amount of carbon in it. We would not see this as the best for serious odor removal. For that we would recommend an air purifier made especially for gas or odor removal. See our air purifier comparison chart for other units designed for this.
