  • Product Overview

    The new Blueair 203 Air Purifier is your solution to cleaner air. If you are living with an aggravating allergy, asthma, or respiratory condition or if you simply want to create cleaner, more breathable indoor air, the Blueair 203 is for you. With value-adding features such as multi-stage filtration, high CADR (Clean Air Delivery Rate) ratings for its class, quiet operation, a filter change indicator, simple maintenance, and Energy Star-qualified operation, the Blueair 203 delivers top-notch results at an economical price.

    Three Levels of Filtration

    Like other Blueair models, the 203 unit filters the air using the company's patented HEPASilent technology and 3-stage filtration. On its lowest speed, the 203 traps 99.97% of particles sized at 0.1 micron using a combination of mechanical and electrostatic processes. Each unit comes with a standard particle filter kit. For additional smoke or odor control, an optional SmokeStop Filter Kit is available for purchase.

    • Particle Filter – This filter is made of polypropylene and a small amount of activated carbon. Best for removing allergens, the filter is capable of collecting dust, pollen, bacteria, pet dander, mold spores, and other airborne particles that can easily trigger symptoms. The filter's activated carbon component is effective in removing some odor and gas traces.
    • SmokeStop Filter – This polypropylene particle filter is enhanced with under a pound of activated carbon. Best for use in spaces where odors and gaseous pollutants are present, this filter removes cigarette smoke, cigar smoke, and other volatile organic compounds – in addition to allergen particles.

    To help maximize filtration effectiveness, the 203's internal ionizer exerts a negative charge over incoming particles, which helps them become more readily captured in the filter. To maintain the unit's optimal air-cleaning performance, remember to replace the filter every 6 months. The unit's magnetic filter replacement indicator will remind you when it's time.

    Cleans and Replaces Air 5 Times Per Hour!

    Remarkably, the Blueair 203 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 (240 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.

    Quiet Operation

    Specialized materials, such as noise-muffling galvanized steel, and precision Swedish engineering help this Blueair air purifier clean your indoor air without the noise associated with less-advanced units. On its lowest setting, the 203 model emits less sound than a desktop computer (32 decibels). Helping it to achieve exceptionally quiet operation is its HEPASilent filter system. Because the filter traps particles using both mechanical and electrostatic means, room air flows more freely throughout the unit. Since air passes more easily through the lightweight filter, the unit's internal fan does not have to work as hard or as loud to generate air movement.

    Kind To The Environment

    Energy Star-rated, the Blueair 203 uses significantly less power than other units, which means you can run the system round-the-clock without seeing a steep jump in your electricity consumption. In addition, the 203 emits zero ozone and is constructed of environmentally friendly parts and materials to help protect the planet as you protect yourself with cleaner air. The Particle and SmokeStop filters are made of non-toxic polypropylene, which ultimately breaks down into water and carbon dioxide when burned. These filters also contain no triclosan or other harmful chemical additives. The air purifier's galvanized steel housing is powder-coated for endurance and protection, without introducing the possibility of chemical outgassing. Lastly – while they are built for years of effective use – all Blueair air purifiers, including the 203, are designed to be disassembled and the components sorted and recycled.

    Other attractive features of the Blueair 203 Air Purifier include:

    • Maximum room coverage of 240 sq. ft.
    • Easy-to-use manual control knob
    • 3 selectable fan speeds
    • Easy-change filter
    • High CADR scores in its class for dust (115), smoke (115), and pollen (115)

      Comments about Blueair 203 Air Purifier:

      This was purchased for use in a medium size office due to continued allergic reactions and congestion I was experiencing from an irritant present in the air. I was recommended to purchase the Blueair brand by a colleague of mine. After just a couple of days of use, many of my symptoms subsided and have not returned. After several weeks of use, I continue to move it into different locations to try and determine where it is most effective.

        Comments about Blueair 203 Air Purifier:

        I use this purifier in the basement bedroom, which would otherwise be quite musty. I've had the purifier for years now and it still works perfectly. It looks nice, it's quiet. It makes a big difference to the mustiness of the room. As someone with allergies, having this purifier made it possible for me to use this room in my house.
