Why do I need an air purifier?
In the U.S, 47% of people live in an area where pollution levels are often too dangerous to breathe. That being said, not many people know that, on average, indoor air is two to five times worse than outdoor air, and it can be up to a hundred times worse. We know it’s hard to imagine, but our indoor air is chock-full of pollutants such as dust, pollen, mold, radon, carbon monoxide, and other dangerous chemicals. These pollutants contribute to asthma, lung disease, lung cancer, and other health issues, and are especially dangerous to children and people with compromised immune system functions. The regular use of an air purifier removes these dangerous particles from the air and lowers the risk of related health issues. They also offer relief to people suffering with allergies and asthma.

What does CADR mean?
CADR or, Clean Air Delivery Rate, is the measurement of the efficiency of an indoor air purifier. CADR is tested according to the American National Standard by the American National Standards Institute (ANSI) and the U.S. Environmental Protection Agency (USEPA) in its Energy Star Program. For consumers to accurately compare product quality, CADR is tested and certified by an independent organization, the Association of Home Appliance Manufacturers (AHAM). The rating is based on room size and measures the three most common indoor air pollutants, pollen, smoke, and dust. CADR ratings are usually found on product packaging, although AHAM testing is completely voluntary. Because we take pride in the quality of our products, we have each and every one of our air purifiers tested and certified by AHAM. We believe making the choice to buy an air purifier is an important investment in your family’s health and would like you to make that choice based on honest information.

We recommend considering a few factors when looking to purchase an air purifier. To properly compare products, you should consider room size, Clean Air Delivery Rate (CADR), energy consumption, and filter type. The first thing to consider when buying an air purifier is the size of the room you’re buying the unit for. Air purifiers are created for particular room sizes, and are tested and rated based on their recommended room size. An air purifier with a recommended room size of 300 square feet would not perform as well in a larger room, but they will perform better in a small room size. As a rule, always buy an air purifier with a recommended room size the same or larger than your room.
A second, and possibly the most important aspect to consider when comparing air purifiers, is the Clean Air Delivery Rate (CADR). The CADR is the rating measuring the efficiency of an air purifier by an independent organization: the Association of Home Appliance Manufacturers (AHAM). This certification is voluntary and takes into account room size, measuring the volume of clean air produced each minute. Measured in cubic feet per minute, the higher the CADR, the better the air purifier. Rated in the top three most common indoor air pollutants, dust, pollen and smoke, the CADR can differ by pollutant. When these ratings differ, you should consider the CADR for the pollutant that affects you most. Energy consumption can easily be overlooked when comparing air purifiers, but as a consumer it is important to remember, higher energy consumption means higher cost. Air purifiers are intended to run 24 hours a day, so they lower the wattage the better. To keep things in perspective, a refrigerator estimated as using around 700 watts running 24 hours a day can cost you around $700 dollars a year on your electricity bill.
When it comes to air purification there are a four different types of filters to choose from, HEPA, ionic, UV, and carbon. It’s important to weigh the pros and cons of each filter type and to choose the one or combination of two, that best fits your needs. High efficiency particulate air (HEPA) filters are those that meet the United States Department of Energy’s standards for efficiency. These filters must remove 99.97% of 0.3 micron particles. Efficiency is measured at this particle size, because it is the most difficult particle size to filter, known as Most Penetrating Particle Size (MPPS). HEPA filters remove dust, pollen, mold, allergens, and bacteria. Ionic filters use negatively charged ions to attract positive airborne particles in the air, weighing down the particles so that they fall to the floor. This type of air filtration only removes airborne particles and is unable to remove particles from surfaces in the room.
Air purifiers that use UV light use electromagnetic radiation to destroy bacteria and viruses. While they work well to remove germs, they are ineffective in removing allergens, dust, and other solids in the air. Activated carbon filters work through a chemical reaction to pollutants as they pass through the adsorbent pores of the filter. While carbon filters do not remove dust and allergens from the air, they are highly effective at removing chemical fumes, gases, smoke, and odors.
What is a micron? And why does it matter?
A micron, or micrometre, is a unit of measure equalling a millionth of a meter. We use this super small unit of measure to measure the size of the particles in our air. We can categorize particle sizes into three categories: large, medium, and small. Larger particles, measuring over 100 microns, include: pet dander, room dust, and some molds. Medium sized particles, measuring from 1 to 100 microns, include: pollen, large bacteria, and small dust particles. Small particles, less than 1 micron, include: viruses, small bacteria, smoke, and chemical fumes.
But why do these sizes matter? Although particles at all sizes can irritate airways and cause allergic and asthmatic responses, particles measuring around .3 micron are the most dangerous to our health. At this size, known as the most penetrating particle size, particles are small enough to pass through the nose and mouth and into the gas exchange area of the lungs, but are too large to be easily exhaled. These particles get stuck in the lung tissue and can cause a wide range of health issues, including: headaches, cardiovascular disease, and even cancer.
Can Blueair purifiers remove smoke and harmful gases?
Yes. Our SmokeStop™ filters are specifically designed for environments with tobacco smoke, auto exhaust, chemical fumes, odors, and harmful VOCs. We use 2 - 4 lbs of coconut-shell activated carbon, formulated with a unique blend of Potassium Hydroxide and Potassium Iodide, to trap gases and fumes and remove them from your air.

Can Blueair purifiers trap airborne bacteria?
Yes, absolutely. Our filters use patented HEPASilent® technology to trap 99.97% of airborne bacteria particles down to .01 micron. The combination of mechanical and active electrostatic filtration provides an exceptionally high level of protection against airborne bacteria and ensures bacteria particles are never released back into the air.

Does using a Blueair system have any environmental impact?
Blueair air purification systems offer exceptional performance with minimal impact on the environment. We have designed every component to improve both human and environmental health, from the non-toxic filter media to the exterior finish. Our units are energy efficient and are constructed of superior materials for an exceptionally long service life. All components are recyclable.
Blueair systems are designed and manufactured to provide years of service. The Blueair system housing is made of galvanized steel, rather than petroleum-based plastic. Steel is more durable than plastic, so the housing holds up over time.
Blueair strives to use environmentally friendly materials to manufacture its products so that they can be recycled at the end of their useful service life. When you are ready to replace your Blueair unit, you'll find the entire system designed for quick disassembly to make recycling easy and practical. Should a Blueair unit end up in a landfill instead of being recycled, its steel housing releases no toxins into the environment. Blueair systems also use a special powder coat finish that produces no chemical outgassing.
NO CHEMICAL ADDITIVES.
Because polypropylene fibers are waterproof, Blueair systems do not require the use of chemical-based bacteriostats or mold inhibitors. Instead of absorbing the moisture in which bacteria thrive, polypropylene repels water and naturally prevents bacteria, mold and mildew from reproducing inside the filter.
Blueair's advanced fan assembly consumes very little energy. In fact, our systems use no more power than a single light bulb: from 5 to 20 watts on low to 10 to 120 watts on high, depending on the unit. Any appliance that can achieve high efficiency with lower power use helps reduce our overall consumption of fossil fuels.
Does Blueair's ionization process produce dangerous levels of ozone?
All Blueair products are tested in accordance with the California Air Resource Board (ARB) certification program, the most stringent requirements in the world for air purifiers. Working with Intertek, an ARB accredited test lab, Blueair products each undergo a comprehensive series of tests to measure ozone emissions. The tests go on for 8-hour long test periods. Air purifiers are tested on high and low speed – with and without the filter installed. No Blueair products tested and investigated produced detectable ozone levels.
All Blueair air purifiers comply with the requirements of the UL Standard 867 Section 37.1.2 criteria for emitting a maximum ozone concentration of less than 0.050 ppm, but also no measurable ozone concentration was detected at all.
How can I get the most from my Blueair system?
Close your windows. You wouldn't throw open your windows on a hot summer day and expect your air conditioner to work efficiently, because you can feel the hot air coming in and the cool air going out. Even though you can't see the contaminated air coming in and the clean air going out, the same logic applies to your air purifier.
Close your doors, too. Just as you might seal off part of your house on a cold winter night to keep your heater working more efficiently, seal off the room in which your system is working for best results. This is especially important for people using a Blueair system to ease nighttime asthma or allergy attacks.
Run your system 24 hours a day. Blueair systems are designed for phenomenally low power usage, so you can run the system 24/7 without a jump in electricity consumption. In fact, it costs about the same to power one of our air purification units as it does to power a single light bulb: between 5 and 120 watts, depending on the unit and the operating speed.
Vacuum or wipe clean. If visible "fluff" builds up on the outside of the air intake grids, as it can in dustier parts of the world, simply vacuum it away or wipe clean with a damp cloth. The air intake grid is designed in part to intercept very large particles before they enter the system, thereby prolonging the life of the filter. The 402 units may also be vacuumed on the inside, if necessary, while the side panels are open for filter replacement.
How often should I change the filter in my Blueair unit?
The filter should be changed every six months, or 188 days, to keep your Blueair unit working at its highest efficiency. In ECO10 units, the filter should be changed once a year.
My unit has suddenly turned off and won’t start again. Is there something I can do to fix it?
If you are having trouble getting your unit to turn on, first try the plug on the bottom of the unit. Most of our units has detachable plugs that can slip out on occasion, if the unit or cord is moved or hit while cleaning. Check your cord by gently placing your unit on its side, remove the plug and replug it in with a good push. If that doesn’t work, give our customer service a call at 1.888.BLUEAIR to discuss options for repairing and replacing your unit. Contact us ›
Will my Blueair purifier work overseas?
Our North American units are made specifically for the North American power grid, meaning they are set to 120v. If you need a unit that will run on 220v, please visit our global where to buy page to find a dealer in the country where you will be using the unit.
Can I turn off the blue LED light next to the logo?
You can’t, but we can send you a magnet to place over the light that will keep with the design of the unit and block the blue light. Just as give us a call and ask for a “Night Cap”.
