  • Product Overview

    • Energy Star Rating: This air purifier qualifies under the Energy Star program for efficient operation, saving you money on long-term operating costs.
    • Digital Controls: To give you further control over the 450E's energy use, a digital display allows for precise control selections. Program the unit timer, view the status of the electronic particle and gas sensors, set the purification speed, and get notification when it's time to replace the filter. A remote control is also included for the ultimate in user convenience.

    How Blueair Air Purifiers Work

    The Blueair 450E is the system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air. This unit effectively purifies air in rooms as large as 365 square feet. Using patented two-stage HEPASilent™ technology, it captures 99.97% of the tiniest 0.1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles.

    This same filter technology earned the larger Blueair 501 Best of Class ranking in independent testing of Clean Air Delivery Rates. The 450E provides comparable performance for mid-sized rooms.

    Value-added features include quiet operation, low energy use, steel construction and easy maintenance. Included with this unit is a standard filter set.  For maximum efficiency, the filter is required to be replaced every six months: simply open the side, slide out the used filter and drop in replacement filter.  For additional smoke or odor control, an optional SmokeStop carbon filter set is available for purchase.

    Cleans Air Quietly

    Sophisticated materials and precision engineering allow the filter to clean indoor air without the noise associated with less advanced units. On the lowest setting, the units emit no more sound than a desktop computer. To achieve exceptionally quiet operation, this air cleaner's patented HEPASilent™ filter technology traps particles two ways: with mechanical and electrostatic filters. This combination creates a filter system through which air flows freely. Most air cleaners require a powerful, noisy fan to pull air through densely packed filters. Since air passes easily through the filter media, the fan doesn't have to work as hard or as loud. Even the housing is designed with quiet operation in mind, replacing sound-sonant plastic with noise-muffling steel.

    Cleans and Replaces Air 5 Times Per Hour!

    Remarkably, the Blueair 450E is able to achieve an air change rate of 5 air changes per hour. This means the air purifier cleans and completely replaces all of the air in the target size area (365 square feet) 5 times in a given hour. Not many comparable air purifiers can do the same, and this is one of the things that sets a Blueair purifier apart from the competition. You'll enjoy cleaner air and fresher air as the day goes on.

    Surround Air

    Instead of discharging a windy stream of filtered air, the Blueair 450E diffuses air gently through an area six times greater than the average air cleaner of the same class. Operating on its lowest setting, the 450E produces virtually no noticeable draft, while still providing an exceptional air exchange rate. The SurroundAir™ system achieves peak performance without annoying drafts by drawing in dirty air from the sides and bottom, moving it through a less dense filter media, and releasing clean, filtered air from the sides and top.

    Energy Star-Qualified

    The Blueair E Series is Energy Star-qualified, which helps save the environment and save you money. Phenomenally low power usage means you can run the system 24/7 without a jump in electricity consumption. In fact, it costs about the same to clean the air in your home as it does to power a single lightbulb: only 20 watts on low to 80 watts on high.

      Comments about Blueair 450E Air Purifier:

      I have been a Blueair customer for 15 plus years and wouldn't depend on any air purification system other then a Blueair. To spend your money on anything else would be nonsense. Only trust a Blueair with my family and my furry love ones.
