  • Product Overview

    The new Blueair 503 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 503 is for you. With value-adding features such as multi-stage filtration, high CADR (Clean Air Delivery Rate) ratings, quiet operation, a filter change indicator, simple maintenance, and Energy Star-qualified operation, the Blueair 503 delivers top-notch results economically and efficiently. The Blueair 503 is highly recommended by a leading consumer reporting agency. Rigorous product testing has confirmed its great ability to remove dust, pollen, and smoke as well as its low noise level when operating in your environment.

    Multiple Levels of Filtration

    Like other Blueair models, the 503 unit filters the air using the company's patented HEPASilent technology and 3-stage progressive filtering. On its lowest speed, the 503 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 Kit – This filter kit includes three particle filters made of polypropylene and a small amount of activated carbon. Best for allergy-sufferers, the filter is capable of removing 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 Kit – This filter kit includes three polypropylene particle filters that are enhanced with a total of 5.3 lbs. of activated carbon. Best for use in rooms 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 503'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 kit 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 503 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 (580 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.

    Efficient SurroundAir Technology

    Using SurroundAir Technology, the Blueair 503 air purifier gently diffuses a draft-free stream of air throughout an area that is six times greater than a comparable unit. This technology works by gradually drawing in contaminated air from the sides and bottom of the unit, passing it through a filter that is lighter in weight than others, and releasing the filtered air out through the sides and top of the air purifier. When operating on its lowest setting, the 503 produces virtually no noticeable draft. At the same time, it provides an exceptional air exchange rate.

    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 503 model emits no more 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.

    Environmentally Friendly

    Energy Star-rated, the Blueair 503 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 503 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 503, are designed to be disassembled and the components sorted and recycled.

    Other attractive features of the Blueair 503 Air Purifier include:

    • Maximum room coverage of 580 sq. ft.
    • Easy-to-use manual control knob
    • 4 selectable fan speeds
    • Easy-change filters
    • High CADR scores for dust (375), smoke (375), and pollen (375)

        Comments about Blueair 503 Air Purifier:

        After a couple weeks of research, I decided to buy an air purifier to help with my allergies. The Blueair 503 has made a difference, and I notice much fewer allergy symptoms since starting to use the air purifier.

        Even though this isn't the cheapest air purifier available, it works great! Currently, I use this in my living room, but lately I've been bringing it my bedroom at night and I have been sleeping so much better. I'm planning to buy a second unit to keep in my bedroom all the time.

        Overall, this is a great product and I would definitely recommend it to friends with allergies or that want cleaner air.

          I use this in my bedroom. I live in a small apartment that is pretty old and my neighbor smokes inside. This purifier really helps with the smell and my room air feels better too. Definitely a good buy.
