After using the Blueair 203, many customers report a significant improvement in air quality, a lessening of allergy and respiratory symptoms, and a more restful sleep. Many also comment on how solidly the unit is built, how easy it is to maintain, and how satisfied they are with their purchase.

What makes a Blueair a Blueair?

  • Superior Particle Filtration and Clear Air Delivery

    Blueair's patented HEPASilent™ technology uses mechanical and electrostatic filters to trap up to 6 times more dirt and particles than other brands. The 3-stage HEPASilent™ filter progressively captures 99.97% of particles down to 0.1 micron, including dust, pollen, dust mites, pet dander, mold spores, bacteria and viruses. ∗ Blueair's unique technology uses less dense filter media to achieve the same efficiency as traditional filters. Less dense filters means lower air resistance, which translates into more clean air delivered at a faster rate (with minimal noise and lower power consumption). Additionally, Blueair's filters resist clogging, so peak filter efficiency is maintained for longer periods than traditional filters. No other air purifier in this price class can offer this.

    ∗    While the HEPASilent Particle Filter also captures some light odors and gases, Blueair's optional SmokeStop™ filter (which also includes HEPASilent particle filtration) removes 98% of gases, odors and VOCs, and is recommended where removal of gaseous pollutants is a concern.

    All Blueair air purifiers are regularly tested and assigned an AHAM-Certified ¹ clean air delivery rate (CADR). The Blueair 203 has earned an AHAM-Certified CADR rating of 155, which means you can be assured the Blueair 203 delivers certifiably clean air in rooms up to 240 square feet.


  • Quiet Operation

    Blueairs are known throughout the industry as some of the quietest. The best test of that is customers, who consistently describe their Blueair as "very quiet," or "barely audible," particularly at the low and medium settings. While the units will be somewhat louder on the third speed, all Blueairs (except for the 650E) will be quieter than or nearly as quiet as all other brands at that speed.

    The larger 403, 503 and 603 Blueairs are 4-speed models. The 503 and 603 move air especially fast at speed four (the "MAX" setting), so there will be some noticeable noise difference at this setting. Bear in mind, this super-charged setting is typically only needed for short-term, quick air cleaning.


  • Ease of Use and Low Maintenance

    Blueairs come ready to be plugged in, with filter(s) included. Most models use a manual rotary dial to switch between fan speeds. The 450E and 650E models come with electronic controls and a remote. All models come with a digital countdown timer so that you know when to change the filter(s).

    Filter changes are simple and take less than a minute. The Blueair 203, 403 and 450E require one (1) HEPASilent particle filter. All other models require three (3) filters, which are sold as a set.  


  • Appealing Design

    Blueairs have a sleek, uncomplicated look with crisp lines and a Swedish-styled simplicity that discretely blends in anywhere. Housings are made of a powder-coated galvanized steel for strength and durability.


  • Earth-Friendly Components

    Blueair filters use non-toxic polypropylene, which produces only water and carbon dioxide as it decomposes, and is much safer than triclosan-coated paper and glass filter fibers. Polypropylene fibers are waterproof (so inherently antimicrobial), therefore no chemical additives are needed to repel moisture. Blueair's non-toxic, powder-coated housing produces no chemical off-gassing. Blueairs are made to be long-lasting, but can be quickly dismantled and recycled at the end of their service life.


  • Low Power Consumption and Zero Ozone Emission

    All Blueairs are Energy Star® rated. Blueair's fan assemblies consume very little energy, requiring no more power than a light bulb. HEPASilent™ filter media is designed to maximize airflow through the filter, putting less strain on the motor, thereby consuming less power.

    Low electrical currents minimize ozone production, and a sealed steel housing keeps any ozone contained within the unit, actually emitting air with less ozone than incoming air. All Blueair models have been tested by the California Air Resource Board (CARB) (per tests outlined in section 37.1.2 of the Electrostatic Air Cleaner Standard, UL 867). CARB has certified each Blueair model to be compliant with the federal ozone emissions limit.

How HEPASilent Works:

  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. ²
  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 bacteria and exhaust. Together, the encapsulated ion chamber and 3-stage filtration combine to create Blueair's patented HEPASilent™ technology ‐ delivering maximum airflow with minimum noise.

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


¹ This Blueair air purifier is certified by the Association of Home Appliance Manufacturers (AHAM) for the Clean Air Delivery Rate (CADR) that has been assigned to the unit. AHAM's Portable Electric Room Air Cleaner Verification Program provides assurance to the public, through the presence of the AHAM Verification Seal, that the manufacturer's claimed CADR ratings have been independently verified in accordance with ANSI/AHAM Standard AC-1.
² The process works a little differently with the Blueair 203, where air passes through the filter first and then through the ion chamber where it is negatively ionized. Once clean air is released through the top, the ions become charged, and as they recycle back through the unit are trapped by the electrostatic filter media.
³ Blueair air purifiers come standard with a 1-Year Limited Warranty. This can be extended to 5 Years by completing and submitting the Blueair Warranty Application that comes with the product.

You can never go wrong with a Blueair, but if you've never owned one, the Blueair 203 is the perfect starter model. Small, quiet and efficient, the 203 has everything to offer to anyone in need of better air quality. Sleep with this baby in your bedroom, and you will notice an almost immediate difference in better breathing and sleeping.
