Blueair 503 Smokestop Air Purifier

Blueair 503 Smokestop Air Purifier


For excellent filtration of airborne allergens plus the added benefit of absorbing fumes and odors, the Blueair 503 Smokestop Air Purifier is a perfect choice for a large room (about 580 square feet with the recommended 6 air changes per hour). The quiet operation allows Blueair to provide cleaner air without disturbing sleep or conversation. HEPASilent Techology works to remove 99.97% of airborne allergens as small as 0.1 micron, while the added activated carbon in the Smokestop filter eliminates irritating odors and fumes. Quality Swedish design makes Blueair as reliable as it is attractive. 1-Y. Mr. Limited Warranty.

A Word of Caution: 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.

Blueair Air Purifiers and Blueair Filters are subject to Minimum Advertised Pricing (MAP).

Additional Info

Blueair 503 Smokestop Air PurifierProduct Notes:

  • Blueair electric air cleaners are easy to maintain - simply open the unit's lid, lift out and drop in the replacement filter every 6 months.
  • The Smokestop filters provides better protection from smoke and other airborne gases.
  • Blueair electronic air cleaners use very little energy, earningthem the coveted Energy Star rating.

The Smokestop models also utilize HEPASilent Technology that works like this:

  1. Air is drawn into the Blueair 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.

Blueair 503 Smokestop Features:

  • System housing: Blueair air cleaner units are made of top-quality galvanized steel so they're durable and long-lasting.
  • HEPASilent filter technology: Traps particles with mechanical and electrostatic filters.
  • Smokestop filtration: The additional highly activated carbon filter absorbs odors and fumes from cigarette smoke and volatile organic compounds frequently found in the home.
  • Low Energy Consumption: Clean 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 outgassing.
  • 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 (according to the Ozone Test outlined in section 37 of the Electrostatic Air Cleaner Standard, UL 867).
  • Sleek Contemporary Design: Blueair 503 Smokestop has earned one of the most prestigious design awards in Scandinavia, and a spot in a permanent exhibit at The National Museum in Stockholm.
