The Complete Buying Guide to Blueair Air Purifiers: Every Model Explained

Blueair has over 20 years in the air purifier business — and too many units to keep track of, so we did it for you.

Welcome to Brand Breakdown, a series of comprehensive yet easy-to-digest guides to your favorite companies, with insights and information you won’t find on the average About page.

While vacuum cleaners have Dyson, air purifiers don’t have the same kind of go-to brand. Instead, there a boatload of air purifier brands, each with its own flagship models that deserve to be in your home fighting off the invisible particles hovering around your head. Blueair is one of those brands. The Swedish-founded brand of air purifiers has been around for over 20 years, and it’s got the inventory and technology to back its long history in the product category. The only problem with Blueair is that it makes so many products that it’s hard to pick the right one for you. For example, what’s really the difference between the Classic line and Blue line? We break it all down for you here.

Need to Knows

Activated carbon: A type of porous material that is good for absorbing unpleasant odors for the air. It is not apt at removing VOCs from the air.

Air quality: The extent to which the air is free of pollutants, which is usually expressed as an average concentration during a given time period.

Air quality index (AQI): A scale from 0 to 500 that reports air quality and the amount of pollutants in the air. The lower the number, the cleaner the air. For ranges on AQI, see AirNow’s chart for more.

Allergen: In short, any substance that can cause an allergic reaction. Potential allergens include pollen, pet dander and mold spores. Allergens can have a reactionary effect through touch or inhalation.

AHAM-Verified mark: Products tested and approved for the Energy Star program by The Association of Home Appliance Manufacturers. Air purifiers with this certification ensure that the device’s “energy consumption rating is consistent with the measured energy consumption,” per the Aham Verifide website.

Clean-air delivery (CADR) rating: Established by the Association of Home Appliance Manufacturers, clean-air delivery ratings measures an air purifier’s effectiveness by noting the volume of clean air produced per minute based on the space of a room. Devices will be given a rating for smoke, pollen and dust, with the higher the number, the better the efficacy.

Pollutant: Any substance that, when in large concentrations, can degrade health conditions.

True HEPA filters: High-efficiency particulate air filters that must remove 99.97 percent of particulates measuring .3 micron in diameter. These have become the baseline for all air purifiers. If you find a filter rated as HEPA-type, don’t buy it as it’s trying to sell you an inferior product — by using the HEPA buzzword — with weaker filtering capabilities.

Volatile Organic Compounds (VOCs): Compounds with high vapor pressure and low water solubility that are emitted as gases from solids or liquids. These can come from things such as paints and pesticides. VOCs, a common type of indoor pollution, can accumulate easily, especially if you rarely open a window. Inhaling VOCs can lead to adverse health reactions and may cause cancer.

Classic Models

It’s hard to be the classic. Blueair’s Classic line of air purifiers is probably the best for any type of person. Set it up and let it run continuously for 24/7 protection against allergens, dust and other crud. These models are quiet and fairly basic in design, so they’re a background protector against all things airborne.

Coway AP-1512HH Mighty Air Purifier

Few air purifiers off the strength and CADR ratings of the Airmega AP-1512HHS at this price point. It has a triple filter system, a pre-filter, HEPA filter and activated carbon filter, plus an ionizer. Throw the device in auto mode, and let the machine do all the work.

Coway Airmega 250

Coway’s newest product blows away its competition. It’s surprisingly small despite its powerful air purification, and it does so without being stupid expensive. It carries over the look of its best-looking unit, the Airmega 150, and packs similar power to the brand’s strongest air purifier, the Airmega 400.

Ikea Fornuftig

Ikea’s air purifier proves everyone deserves clean air without having to pull from their savings. The Fornuftig is slim and efficient, and it doesn’t call attention to itself because it’s not an eyesore. It also hangs on the wall so it’s completely out of the way.

Blue Models

Blue is Blueair’s design-conscious line of air purifiers, combining the Classic’s effectiveness with just a tad more style. They’re definitely more compact and portable than the other ranges, and for most models, you can expect a lower price tag. The fabric pre-filters let you swap out different colors to tailor your unit to your home, and all the Blue models have 360-degree protection, so you can really place them anywhere without compromising efficiency.
