Air Purifiers

Air Purifiers for Cleaner, Healthier Indoor Air

The air inside your home can carry two to five times more pollutants than the air outside, according to the EPA. Dust, pollen, pet dander, smoke, and fine particles circulate every time you open a door, run the heat, or live with a pet. A good air purifier pulls them out.

Blueair has been building air purifiers since 1996 in Sweden, and in 2025, Consumer Reports top-rated air purifiers named us the best air purifier brand of the year. Every purifier in this collection runs on HEPASilent technology, a filtration approach that pairs mechanical and electrostatic filtration to capture more particles with less noise and lower energy use than standard HEPA alone.

Whether you need something for a bedroom, a living room, a large open floor plan, or a home dealing with allergies and pets, there’s a model sized and designed for that space below.

Find the right purifier for your space

Blueair air purifiers are organised by the room size they’re designed to clean:

Small rooms under 25 M² — bedrooms, offices, nurseries, and small dens. Quiet, compact, and built to run overnight without disrupting sleep.

Medium rooms  25–40 M² — most living rooms and primary bedrooms fall here. Models in this range offer a balance of coverage, price, and noise.

Large rooms over 40 M² — open-plan kitchens, great rooms, and studio apartments. Browse our air purifiers for large rooms with high CADR ratings for faster air turnover and cleaner spaces.

Extra-large rooms over 60 M² — the Blue Signature series handles spaces up to 92+ M². If you have high ceilings or an open layout, these are the ones to look at.

Room sizes listed with each model are based on running the purifier at medium speed for two full air changes per hour, the standard used by Consumer Reports and AHAM. Run at high speed, most models cover an even larger area.

What HEPASilent filtration actually means

Most air purifiers use a True HEPA filter, which captures 99.97% of particles 0.3 microns or larger. That’s the industry benchmark, and it works.

Blueair’s HEPASilent technology does something different. It adds an electrostatic charge to incoming air particles, which makes them stick to the filter more easily. The result: the same level of filtration at a lower fan speed, which means less noise and lower electricity use. At high speeds, HEPASilent purifiers clean more air per minute than a standard HEPA unit of the same size.

In Consumer Reports’ lab tests, Blueair models consistently perform well at both high and low speeds — which matters because most people run their purifier on low most of the time.

CADR (Clean Air Delivery Rate) is the metric that tells you how fast a purifier removes dust, pollen, and smoke from a given space. Higher CADR means faster clean air delivery. Every model on this page lists its CADR rating so you can compare directly.

Air purifiers for allergies, pets, and respiratory conditions

Cat and pet dander is one of the most common indoor allergens. The proteins in pet saliva and skin attach to tiny airborne particles that stay suspended in the air for hours. A HEPA-grade purifier running continuously in the rooms where your pet spends the most time, especially the bedroom, can cut down dander and make life with a cat or dog much more manageable for people with allergies.

Pollen, dust mites, and mould spores follow the same logic. They’re small, they float, and they don’t settle quickly. An air purifier with a high CADR for the room size you’re targeting will cycle the air several times per hour, reducing the concentration of particles that trigger sneezing, watery eyes, and congestion.

For people managing respiratory conditions, such as asthma, COPD, or pulmonary fibrosis, air purifiers won’t replace medical treatment, but cleaner air with fewer airborne irritants means fewer triggers. People with pulmonary fibrosis and COPD are often advised to reduce exposure to airborne dust, smoke, and fine particles. Running a purifier in the bedroom and main living area is one of the more direct ways to do that at home.

The best air purifier for your bedroom

The bedroom gets its own section because it’s where most people want the most coverage. You’re sleeping there for 7–8 hours, breathing the same air the entire time.

A few things matter specifically for bedroom use: noise, size, and whether the purifier can run all night safely.

Looking for the best air purifier for bedroom use? Blueair’s sleep models run quietly on their lower settings, typically under 30 dB, which is close to a whisper. The Mini Restful is designed specifically for sleep, pairing HEPA-grade air purification with a built-in sunrise alarm clock that simulates natural light to help you wake more gradually.

Running an air purifier all night is completely fine and, for people with allergies or respiratory sensitivities, it’s actually the most effective approach. Air quality is typically at its lowest in the early morning hours when outdoor air mixes with indoor air. Keeping the purifier running overnight maintains cleaner conditions continuously.

For most bedrooms, a small or medium model is the right size. The bedroom-specific models on this page are clearly labelled, and each listing shows the square footage coverage so you can match it to your room.

Air purifiers for large rooms and open floor plans

Large and extra-large spaces are where most air purifiers underperform. A unit rated for 28 m² placed in a 65 m² living room will work, just not very well. The air turnover rate drops, so the same particles stay airborne longer.

For large rooms, look at CADR first. A CADR of 250 for smoke, for example, means the purifier removes the equivalent of 250 cubic feet (about 7 m³) of smoke-free air per minute. In a 56 m² room with 2.7 m ceilings, that's roughly two full air changes per hour at high speed.

The Blue Pure 211i Max and Blue Pure 3450i Max are built for exactly these spaces. They handle up to 56–93+ m² without working at maximum output constantly, which keeps noise low and extends filter life.
