Additional Info

Product Notes:

  • Blueair's patented two-stage HEPASilent technology, captures 99.97% of the tiniest 0.1 micron particles, including allergy-provoking pollen grains, as well as dust mite, mold spore and pet dander particles.
  • You’ll also sleep better knowing that your Blueair purifier uses very little energy, earning it the coveted Energy Star rating.
  •  A Blueair Purifier easy to maintain - simply open the unit's lid, lift out and drop in the replacement filters (standard filter and carbon upgrade are available above) every 6 months.

 Blueair 303 Features:

  • HEPASilent filter technology: Traps particles with mechanical and electrostatic filters. (See Technical Data Tab)
  • System housing: Blueair purifier units are made of top-quality galvanized steel so they're durable and long-lasting.
  • Low Energy Consumption: Cleaning the air in your home costs about as much as it does to power a single light bulb.
  • Earth-Friendly: Nontoxic polypropylene filter media is one of the least harmful plastics, plus Blueair's powder coat finish produces no chemical offgassing.
  • Zero Ozone Emission: Low electrical currents minimize ozone production and a sealed steel housing keeps any ozone contained inside the unit, actually emitting air with less ozone than the incoming air from the room.**
  • Sleek Contemporary Design: Blueair purifier 303 has earned one of the most prestigious design awards in Scandinavia.

**According to the Ozone Test outlined in section 37 of the Electrostatic Air Cleaner Standard, UL 867.

How HEPASilent Works:

  1. Air is drawn into the Blueair purifier system via its ultra-quiet fan.
  2. Airborne particles pass through an ion chamber and are electrically charged. This causes them to adhere effortlessly to Blueair's exclusive polypropylene filters.
  3. Charged particles are removed in the 3-stage Progressive Filter. Stage 1 captures larger particles like pollen and dust. Stages 2 and 3 filter the smallest particles like cigarette smoke* and exhaust. Together, the encapsulated ion chamber and 3-stage Filtration Process combine to create Blueair's patented HEPASilent technology - delivering maximum airflow with minimum noise.

*No air purifier or air cleaner can eliminate the hazardous contaminants, or the harmful effects of second hand smoke. The best defense is a smoke-free environment.
