Intelligent air cleaning capabilities and remarkable room coverage make the Blueair Classic 605 air purifier the showcase model of the Blueair Classic line. Replacing the popular Blueair 603, the Blueair 605 is not only aesthetically pleasing, but offers advanced functionality, proven effectiveness and years of dependable service. Able to completely exchange the air 4 times every hour in a 940 sq. ft. room, the Blueair Classic 605 is perfect for people seeking exceptional air cleaning for open concept or over-sized living spaces.

Precision Swedish engineering has made the new Blueair Classic 605 even more energy efficient, requiring a mere 15 watts of power on its lowest fan speed setting. The user interface has also been improved, with an updated digital display and touch-button control. However, the big news is that the Blueair 605 now has built-in Wi-Fi capabilities, allowing you to remotely control the airflow speed, LED light, child lock and more via your smartphone. Just download the Blueair app and you're all set to control your air cleaning from the palm of your hand, whether you're at home or away.

Blueair 605

While most high-capacity room air purifiers require a powerful fan to draw the air in and force it through the HEPA filtration system, the SurroundAir technology used in the Blueair Classic 605 air purifier attains peak performance without the accompanying noise of a powerful fan. This is accomplished by means of three separate particle filters with progressively smaller openings, and an internal electrostatic ionizer that negatively charges the incoming particles to ensure that they adhere effortlessly to the positively-charged filter material in the air purifier. The bottom line is that the Blueair 605 is able to achieve higher air flow rates, with lower power consumption and less noise than other brands of air purifiers, while still capturing a remarkable 99.97% of particles down to 0.1 microns (i.e., three times smaller than the particles handled by traditional medical-grade HEPA filters).

The standard Blueair Classic 605 air purifier is a great choice for those who only want to control particles, e.g., house and textile dust, pollen, pet dander, fungi/mould spores, dust mite by-products, fine ash, combustion particles, printer/photocopier emissions and other microscopic particulates. However, those seeking added protection from hazardous chemicals, toxic gases and unpleasant odours should invest in the optional Blueair 605 DualProtection filters.

The Blueair 605 DualProtection filters offer wide-spectrum chemical, gas and odour control, while still achieving the same outstanding level of particle collection as the Blueair 605 particle filters. Featuring an activated carbon cloth woven with 100% pure activated coconut carbon, the DualProtection filters provide additional safeguards from tobacco and wood smoke toxins, carbon monoxide and other gaseous combustion byproducts, ethylene oxide, ozone and the harmful VOCs found in every home and workplace (e.g., formaldehyde, ammonia and benzene).

Unlike conventional electrostatic air cleaners, the Blueair Classic 605 air purifier is completely safe for allergy and asthma sufferers because it releases absolutely no ozone or ozone by-products into the air. In fact, the Blueair 605 has been shown to significantly reduce ozone concentrations in rooms where electronic devices (e.g., computers, printers, televisions) are being used.

Rather than using traditional glass and paper filters that are brittle and can splinter easily, Blueair Classic 605 filters are made of more flexible and resilient ultrasonically-bonded, non-woven polypropylene fibres. This material is non-toxic and naturally hydrophobic, inhibiting bacteria, virus and mould growth without the need for chemical additives or washes.

To maintain optimal air cleaning performance and ensure warranty coverage, the three filters in the Blueair Classic 605 air purifier must be replaced every 6 months. The Blueair 605 will remind you when it's time to change the filters via the built-in filter replacement indicator. The filters themselves can easily be replaced by lifting off the top grill of the Blueair 605, removing the old filters, sliding the new ones in and replacing the grill. Quick and simple!

Constructed of noise-muffling galvanized steel instead of resonating plastic, even the housing of the Blueair 605 air purifier is designed with quietness in mind. On its lower fan speed settings, the Blueair 605 offers whisper-silent operation, with sound levels so low that you may wonder if your Blueair air purifier is actually on.

Blueair awards

Energy Star qualified, the Blueair Classic 605 uses significantly less power than other units on the market, making it not only environmentally responsible, but economical to operate. Made from recyclable materials of exceptional quality, Blueair 605 air purifiers are built to provide years of reliable service. A special powder-coated finish ensures that Blueair air purifiers produce no chemical off-gassing, and to protect the planet, Blueair filter media converts into harmless carbon dioxide and water as it decomposes.

With its sleek and contemporary good looks, the Blueair Classic 605 air purifier offers a quiet solution to your high-performance air cleaning needs. Designed for main floors and open concept living areas, the Blueair 605 is also an excellent choice for suite-style bedrooms, large basements, open office areas and spacious apartments or condos. The Classic 605 has wheels for easy maneuverability, and is a neutral off-white and dark grey colour to complement almost any décor.

BLUEAIR CLASSIC 605/603 - CUSTOMER REVIEWS (Includes reviews for the non Wi-Fi enabled model 603)

“I have severe allergies to all grasses, pollen and dust and also live in an extremely dusty old apartment building. After doing a lot of research on air purifiers, Blueair was an easy decision. Consumer Reports and a recent CBC Marketplace episode rated Blueair as their best performing air purifiers. Robert helped me pinpoint which purifiers were right for me based on my apartment layout and allergies. I bought two Blue Pure 411+ units for my home office and bedroom, and the Classic 605 for the open area living space. WOW! The difference in air quality was dramatic within just days. And after two weeks with the purifiers on 24/7, I’m very happy to report that the itchy eyes, the clogged sinuses and scratchy throat have almost completely disappeared! Needless to say, I’m absolutely thrilled. This was an excellent investment.”
T Brown, Verdun, QC

“The Blueair 605 air purifier arrived today, and after only a couple hours on medium, the basement smells amazingly fresh. Very impressed! No more musty dank basement smell. Can't thank you enough for your help in picking the best system for our needs.” [Note: purchased with GO SmokeStop filters]
Daryle T, Delia, AB

“I purchased the Blueair Classic 605 and the Blueair Pure 211+ in November 2020, and am absolutely amazed at how they have transformed the air quality in my home! After running the units for a few days, I visually noticed two things. One, that there was minimal dust on my furniture and two, there was no dust floating in the air. My front door has a glass window, and on a sunny day a ray of light shines through and one could see the dust floating in the air. Now, the ray of light has disappeared and only the sunlight shines through the door. Another huge difference is how the air quality has changed. My home now has that clean smell just like when I used to leave the windows open during a rainfall. Additionally, the air purifiers have removed the cooking smell after every meal, especially bacon and fish. The smell does not linger into the next day. I HIGHLY RECOMMEND Blueair to any consumer wanting to see similar results.”
D Jones, Vancouver Island, BC

“I think my husband is a convert since we got the Blueair 603 air purifier. A few days ago he said he can't believe he doesn't wake up coughing anymore (he has all his life). It was all I could do not to say "I told you so.”
Bonnie W, Ottawa, ON

“The Blueair 603 air purifier that I purchased from you works wonderfully. The Blueair is a 'must' for keeping down dust and smoke particles in my home during the winter season, and as an added bonus, during spring and summer allergy season.” [Note: purchased with DualProtection/SmokeStop filters]
J. Smith, Magog, QC

“We bought a Blueair 603 air purifier from you last summer because my wife has asthma and is also allergic to numerous airborne substances. She really noticed a difference after the first day we had the air purifier in our home. During the daytime we keep the Blueair in our living room where it does a good job of clearing the air in the main living area. We move it into our bedroom in the evening and by the time we go to bed, that room is cleared. The Blueair 603 is quite easy to move around because it is on casters. During the daytime we run the fan at full speed and at night we turn it down a notch and the sound is almost inaudible. The Blueair 603 isn’t cheap, but it is built very well and it is the first air cleaning unit that really works for my wife, so it has been an excellent investment.”
G Friedel, Edmonton, AB.

“We purchased a Blueair 603 air purifier for our cottage and have it running near the wood stove - It works beautifully!” [Note: purchased with DualProtection/SmokeStop filters]
Andrew and Kit, Lachine, QC

** An Important Word on Air Flow Rates and Room Coverage for the Blueair Classic 605 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 605 be used in rooms of up to 470 sq. ft. (for premium cleaning) or 940 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.
