Compact, whisper-quiet and powerful – these three words describe the new Blueair Classic 205 air purifier to perfection. Replacing the older Blueair 203 model, the upgraded Blueair 205 is a high-tech wonder, not only offering high-performance air purification, but being virtually inaudible and stylish as well. If you are a light sleeper, sensitive to noise or don’t want your air purifier to disturb co-workers in an open office workplace, then the Blueair 205 is the perfect air cleaning solution for you.

The new Blueair Classic 205 air purifier is Wi-Fi enabled, allowing you to remotely control the speed of your air purifier using your smartphone or smart device. By downloading Blueair's app, you will be able to control all of the Blueair 205's functions from the palm of your hand in any location with Wi-Fi. For example, you can turn the air purifier up to high as you leave work so that the air is at its cleanest when you get home. Use of the app is completely optional - the Classic 205 will also perform effectively on its own.

Using exclusive HEPASilent particle filtration technology, Blueair air purifiers outperform ordinary medical-grade HEPA filters by combining mechanical filtration and electrostatic principles to achieve exceptional air cleaning performance. The Blueair Classic 205 air purifier uses an advanced gradient media particle filter that is comprised of millions of ultrasonically bonded, non-woven polypropylene fibres, with each layer trapping progressively smaller – and potentially more harmful – particles. As contaminated air is drawn silently into the large intake at the back of the Blueair 205 air purifier, all but the finest of particles are captured by the filter. The Blueair 205’s internal ionizer than exerts a negative charge over any remaining ultra-fine particles in the air, ensuring that they adhere effortlessly to the positively-charged filter material on their next pass through the unit. This unique design allows the Blueair 205 air purifier to capture an outstanding 99.97% of particles down to 0.1 microns, i.e., 3 times smaller than the particles trapped by traditional HEPA filters.

Ideal for controlling house and textile dust, pollen, pet dander, fungi/mould spores, dust mite by-products and other allergens, the Blueair Classic 205 air purifier is the perfect choice for allergy sufferers and health-conscious individuals who want a quiet, but powerful air cleaning solution. In addition, the ability of the Blueair filtration system to capture smaller particles than conventional HEPA air purifiers do means that the Blueair 205 provides better protection from hazardous, lung-penetrating particles such as ultra-fine dust, combustion particles, fine ash and printer/photocopier emissions, as well as added defence against airborne bacteria.

While the standard Blueair 205 air purifier is intended solely for allergen and particulate matter control, those looking for a more complete air cleaning solution should consider the optional Blueair 205 DualProtection (DP) filter. The DualProtection filter offers wide-spectrum chemical, gas and odour control, while still achieving the same outstanding level of particle collection as the standard particle filter. Featuring an activated carbon cloth woven with 100% pure activated coconut carbon, the DualProtection filter provides additional protection from tobacco and wood smoke toxins, combustion gases from HVAC systems, vehicle exhaust and smog-related gases that may filter in from outside, and the harmful volatile organic compounds (VOCs) that are found in every home and workplace (e.g., formaldehyde, ammonia and benzene).

Traditionally, most high-performance air purifiers that use true HEPA filters in a well-sealed system require a powerful, and inherently noisy, fan to draw large volumes of air through the unit. However, in the case of the Blueair Classic 205 air purifier, the hybrid filtration system achieves remarkable air cleaning results without the need for a heavy-duty fan. On its lowest fan speed setting, the Blueair 205 offers whisper-silent operation with a sound level so low that you may wonder if your Blueair unit is actually on. Energy Star rated, the Blueair 205 air purifier costs pennies a day to operate, making it the ideal choice for those concerned about the impact of running an air purifier 24/7 on their electricity bill.

All Blueair air purifiers, including the Blueair Classic 205, release absolutely no ozone or ozone by-products into the air. In fact, independent laboratory testing confirms that the ozone concentration in the air coming out of a Blueair 205 air purifier is actually lower than that of the incoming air.

While most companies use standard triclosan-coated paper or glass filter fibres in their filters, Blueair uses non-toxic, non-woven polypropylene. Polypropylene is unique in a number of ways. First, it works without releasing irritating microscopic fibres into the air. Secondly, because polypropylene is waterproof, it naturally resists contamination from bacteria, viruses and mould, without the need for chemical additives or washes.

To maintain peak air cleaning performance and ensure warranty coverage, the filter in the Blueair Classic 205 air purifier must be replaced every 6 months. The Classic 205's built in filter replacement indicator will remind you when it's time to change the filter. The Blueair filter can be replaced simply by opening the hinged back panel of the air purifier, removing the old filter, and popping in the new one. Absolutely no tools are required!

Unlike lower quality units, the precision Swedish engineering of the Blueair Classic 205 air purifier makes this unit reliable for years of worry-free operation. Beautifully designed, Blueair 205 air purifiers have all-steel housings that are powder-coated for durability and environmental protection, without any chemical off-gassing. All Blueair air purifiers are constructed from environmentally friendly parts and recyclable components, and when discarded, Blueair filters simply decompose and the media converts into harmless carbon dioxide and water.

The compact size, ultra-quiet operation and effective air cleaning capabilities of the Blueair Classic 205 make it the perfect air purifier for small spaces where noise-free operation is a must (e.g., bedrooms, offices). The Blueair 205 has built-in handles for easy portability, and is a neutral white and dark grey colour to blend into virtually any décor.

BLUEAIR CLASSIC 205/203 - CUSTOMER REVIEWS (Includes reviews for the non Wi-Fi enabled model 203)

“I have found our Blueair Classic 205 to cut down on the dust (noticeably by a lot), but I also feel like I am breathing clearer in our home. I am definitely a believer in Blueair air purifiers and think you definitely get what you pay for. I am also very glad to be a repeat customer. You run a top notch company.”
Jeff L, Toronto ON

“I bought a Blueair Classic 205 air purifier from you to use in my bedroom. I am really happy with it - the air is great, and the filter runs so quietly. I am also most grateful for the excellent service. I really appreciated your advice.” [Note: purchased with DualProtection/SmokeStop filter]
L. Raynes, Ottawa, ON

“I purchased the Blueair Classic 205 air purifier with the DualProtection Filter for the Master Bedroom. It is absolutely great! There is a noticeable improvement in the air quality and it is very quiet. I highly recommend it. Robert was very patient with all my questions and helpful in outlining the different possibilities.”
M Fisher, Toronto, ON

“My two Blueair 203 air purifiers are super. One stays permanently in my painting studio, where even though I no longer use chemical thinners, there are still plenty of other unknown pollutants in the air, and the other stays in my office. Remarkably, when I'm in the rooms with the Blueair 203s, I don't need to use my allergy medications! I'm very happy with these air purifiers and have recommended them to several people. I also appreciate the extra services that you offer, e.g., the filter replacement reminder program and warranty processing.”
M. Becker, Vancouver, BC

“I'm glad to report that I'm very satisfied with my purchase of the Blueair 203 air purifier, and also with your service. So much so that I've recommended it to my company for our office space. I have less dusting to do at home since I've been using the Blueair 203, and am thinking of purchasing another one in the near future.” [Note: purchased with DualProtection/SmokeStop filter]
A. De Angelis, LaSalle, QC

“When researching for an air purifier I was looking for something that was very quiet and offered minute filtration. I chose the Blueair brand because it was well designed. Modern Alchemy Air Purifiers made it easy to purchase our Blueair 203 air purifier. We received excellent knowledge through quick email and telephone responses, and chose the Blueair 203 model to filter out particulates and any possibility of moulds. We now use the unit in our bedroom. It is very quiet on the low setting, but we turn it off when we go to sleep. During the day when the room is unused we run the Blueair 203 at a higher speed and go to bed with refreshed clean air.” [Note: purchased with DualProtection/SmokeStop filter]
K. Ghiglione, Toronto, ON

“My Blueair 203 air purifier is still working great (since October 2012 with continuous use). My office space and computer equipment are dust free! And thanks so much for your outstanding Filter Replacement Program, I just ordered a twin-pack.”
L. Denomey, Belle River, ON

“The Blueair 203 air purifier that I purchased from you has been working wonders for my allergies for quite a few seasons now! Too bad I can’t cart it around everywhere I go!”
K. Inkster, Vancouver, BC

** An Important Word on Air Flow Rates and Room Coverage for the Blueair Classic 205 Air Purifier:

Many retailers and manufacturers overstate maximum room coverage figures by calculating them with air flow rates measured without filters installed (i.e., fan output) or with too low a number of air exchanges per hour to properly clean the room. Modern Alchemy Air Purifiers believes in stating the actual delivered air flow rates for the air purifiers we sell, as well as realistic room coverage figures calculated at effective air cleaning levels. Accordingly, we recommend that the Blueair 205 air purifier be used in rooms of up to 206 sq. ft. (for premium cleaning) or 415 sq. ft. (for general purpose filtration).

Note that air purifier performance should not be judged by air flow rates and room maximums alone. Many features that make an air purifier more effective at cleaning the air actually reduce the air flow rate. For example, higher grade HEPA filters, well-sealed filtration systems and large amounts of carbon all increase air resistance and reduce delivered air flow rates.
