Unlike other models with filters that cannot remove air impurities smaller than 0.3 microns, the three mechanical and electrostatic filters in the Blueair 203 air purifier capture 99.97% of 0.1 micron particles, including allergy-provoking pollen grains, dust mites, mold spores, tobacco smoke, and pet dander particles, resulting in an average Clean Air Delivery Rate of 437.5 – 28% higher than the next air cleaner.

The Blueaire 203 air purifier uses patented HEPASilent filters that allow air to flow freely through the unit, eliminating the need for powerful, noisy fans, and filtered air is discharged diffusely from vents, resulting in no noticeable draft. Despite its quiet operation, the device is powerful enough to recycle air in a 175 sq ft room six times every hour. The filters are easily accessed and replaced, the casters allow ease of maneuverability, and the exterior wipes clean. This new and improved unit also comes with a built in filter change indicator light! Includes one set of filters. Consider the Blueair 203 air purifier as your home air purifier or as your office or business air purifier.

Additional Information
The new Blueair 203 in-room air purifier is the only air purifier with its room capacity to use HEPASilent™ technology, a combination of the best features of electrostatic and mechanical filter technology that allows delivery of more clean air, at a faster rate, with less noise.

The 203 is among the highest energy efficient and quietest operating air purifiers in its class, with a room capacity of 175 square feet.

The unit is available in silver.

Using patented two-stage HEPASilent™ technology, it captures 99.97% of the tiniest .1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles.

The Blueair 203 is the most compact unit in the Blueair line. It is an excellent system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air. This same filter technology earned the larger Blueair 503 Best of Class ranking in independent testing of Clean Air Delivery Rates. The 203 provides comparable performance for smaller rooms.

Environmentally Aware
Blueair products offer exceptional performance without polluting the environment. 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. Because polypropylene is waterproof, our filters naturally resist contamination from bacteria, viruses and mold, without chemical additives or washes. Blueair even uses a special powder coat finish that produces no chemical outgassing.

• Quiet operation
• Low energy use
• Steel construction and easy maintenance: simply open the side, slide out used filters and drop in replacements every 6 to 12 months.
• Filter Change Indicator Light

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.

Surround Air
Instead of discharging a windy stream of filtered air, the Blueair 203 diffuses air gently through an area six times greater than the average air cleaner of the same class. Operating on its lowest setting, the 203 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.

Low Energy Cost
A phenomenally low power usage means that you can run this air cleaning system 24/7 without a jump in electricity consumption.
