The new Blueair Classic 505 air purifier gives the discontinued Blueair 503 a thorough upgrade. The Blueair 505 now delivers enhanced air cleaning performance and better room coverage, but uses less power and is easier on your electricity bill. In fact, no air purifier in its price range provides better room coverage! The Blueair 505 has also been updated with Wi-Fi capabilities, a digital display and touch button-controls. By downloading Blueair’s free Friend App to your smartphone or smart device, you can control all of the Blueair 505’s functions from the palm of your hand, even when you’re not at home.

Blueair's proprietary HEPASilent technology combines mechanical filtration and electrostatic principles to achieve outstanding air cleaning that outperforms medical-grade HEPA filters alone. As room air is drawn into the Blueair Classic 505 by an ultra-quiet fan, an internal ionizer exerts a negative charge over the incoming particles, ensuring that they adhere effortlessly to the positively-charged filter material. Incorporating three separate particle filters with progressively smaller pores, the Blueair 505 air purifier is able to capture a remarkable 99.97% of particles down to 0.1 microns, making it ideal for controlling house and textile dust, pollen, pet dander, fungi/mould spores, dust mite by-products and other allergens. The unique capabilities of the Blueair 505’s particle filtration system also provides better control of hazardous, lung-penetrating particles such as ultra-fine dust, combustion particles, fine ash and printer/photocopier emissions than conventional HEPA air purifiers do, as well as added protection from airborne bacteria.

While the Blueair 505 with the standard particle filters is ideal for allergen and particulate matter control, those requiring added protection from hazardous chemicals and gases should upgrade to the DualProtection filters (optional). These advanced filters use a woven activated carbon cloth to effectively capture chemicals and gases with no reduction in airflow, while simultaneously achieving the same degree of particle capture as Blueair's standard particle filters do. The larger surface area allows the filter to adsorb greater quantities of gaseous pollutants such as VOCs and smoke, without the need for chemical additives.

Like the rest of the Blueair line, the Energy Star rated Blueair Classic 505 air purifier is designed to operate at peak air cleaning effectiveness with minimal noise, draft and power consumption. While most conventional air purifiers require powerful fans to draw air into the unit and force it through the dense HEPA material, the Blueair Classic 505 air purifier uses an exclusive SurroundAir technology to achieve remarkable air cleaning results without the need for a powerful (and inherently, loud) fan. On the two lowest fan speed settings, the Blueair 505 offers whisper-silent operation, with sound levels so low that you may wonder if your Blueair unit is actually on.

The Blueair Classic 505 air purifier not only offers high-performance air cleaning, but releases 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 505 air purifier is actually lower than that in the incoming air.

To maintain optimal air cleaning performance and ensure warranty coverage, the three filters in the Blueair Classic 505 air purifier must be replaced every 6 months. The 505 will remind owners when it’s time to replace the filters via a built-in filter replacement indicator. When the time comes to change the filters, simply lift off the top grill of the Blueair 505, pull out the old filters, slide in the new ones and replace the grill. Nothing could be easier!

Designed in Sweden, the Blueair Classic 505 air purifier has been engineered for years of reliable, worry-free operation. Blueair 505 air purifiers have all-steel housings that are powder-coated for endurance and protection, without any chemical off-gassing. In addition to zero ozone emission, all Blueair air purifiers are constructed from environmentally friendly parts and recyclable materials. When discarded, Blueair filters simply decompose and the filter media converts into harmless carbon dioxide and water.

The sleek design, quiet operation and sheer air cleaning power of the Blueair Classic 505 air purifier makes it perfect for more spacious areas of the house, including over-sized master bedrooms, large basements and open concept living areas. A Blueair 505 would also be an excellent choice for an office or apartment. The Blueair 505 has wheels attached for easy maneuverability, and is a neutral off-white and dark grey colour that suits any room regardless of décor.

BLUEAIR 505/503 - CUSTOMER REVIEWS (Includes reviews for the non Wi-Fi enabled model 503)

“Thanks so much for the kind note and excellent service. Both Breanna and I are having problems with air pollution and smoke triggering our asthma. We were delighted to receive our Blueair 505 air purifier here in Vancouver faster than expected. It's really making a big difference for us. That’s why I’m purchasing a second Blueair unit. And yes, we would like to join your filter replacement program. Thanks again for your help.” [NOTE: purchased with DualProtection/SmokeStop filters]
L.M., Vancouver, BC

“I purchased a Blueair 505 air purifier and a Blue Pure 211+ from you and could not be more pleased. Great service, great products. Thank you!”
CD Ward, Shelburne, ON

“My Blueair 505 air purifier arrived safely, and I’m very pleased with the look of it and the fact that it has wheels. I noticed an immediate improvement in the smell/air quality within hours of operating it. Thanks so much.” [NOTE: purchased with DualProtection/SmokeStop filters]
Joanne C, Oakville, ON

“Being a moderate asthmatic, all traces of pet dander provoke a very unpleasant reaction in my breathing. When I begin to wheeze through my airways, it is quite detrimental to my daily productivity, and sleeping, exercising and studying become difficult. After we renovated our new home with hardwood flooring and had the air ducts cleaned, I found that I was still unable to breathe clearly. We called Robert at Modern Alchemy Air Purifiers, and he gave us a thorough and helpful education on how air purifiers could help our situation. A Blueair 503 air purifier was selected for the basement, and two IQAir HealthPro Plus units were placed in the rest of the house. Within an hour, the air was noticeably easier to breath and smelled better. The very first night I noticed I could sleep through the entire night without waking up. That was amazing, a feat I have not experienced for years! The Blueair 503, which was placed in the basement where I exercise, dramatically increased my endurance while working out.”
Chris C, Ottawa, ON

“I am delighted with my Blueair 503 air purifier. Within hours of turning it on, the dust in my apartment was visibly less and the air so much fresher. I wish I had gotten one sooner.”
Timothy O, Toronto, ON

“Everyone, our rabbits included, is enjoying our Blueair 503 air purifier. It does a good job and it DOES make a difference!”
M. Rhynes, Calgary, AB

“Just a quick note to let you know that the Blueair 503air purifier that I purchased from you is helping considerably. I’m still running for exercise and no asthma to speak of yet. I’m still taking a puffer, but on a reduced basis, just to be on the safe side. So very happy so far and recommending the Blueair units, and your company, to others out here in the Comox Valley where there is a significant winter air quality problem.” [NOTE: purchased with DualProtection/SmokeStop filters]
D. Powsey, Cumberland, BC

** An Important Word on Air Flow Rates and Room Coverage for the Blueair Classic 505 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 standard Blueair 505 air purifier be used in rooms of up to 435 sq. ft. (for asthma and allergy sufferers) or 875 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.
