Genuinely quiet at night. We run it on the bedroom setting and forget it's there until the app shows it working harder during a bad-AQI evening.

Real customer reviews
Bought this after my daughter's allergist recommended a HEPA purifier for her room. Covers the room and the hallway outside it comfortably.
Ordered ahead of the winter smog and it's been worth every rupee. The app notification when AQI spikes outside is the feature I didn't know I needed.
Does exactly what it says. Only reason it's not five stars is delivery took a day longer than promised, unit itself is excellent.
We ordered two for our office floor after staff kept complaining about the AC dust. Noticeably fresher air within a day, and the VAT invoice process was painless.
Was worried about coverage since our living room is fairly open-plan, but it keeps up fine even on the medium setting.

What the HealthProtect™ 7470i gives you

Cleans more air, quietly
HEPASilent Ultra combines electrostatic and mechanical filtration. Blueair says it delivers 50% more clean air, uses 55% less energy and runs 10% quieter than traditional true HEPA filtration. It captures 99.97% of particles down to 0.1 micron, including dust, pollen, pet dander and smoke.
- Cleans a 418 sq ft room in 12.5 minutes
- Handles about 980 sq ft in 30 minutes

Protection that keeps working on standby
Even when the purifier is on standby, GermShield watches the room and removes viruses and bacteria on the filters using a low air draught and a plasma charge. Blueair backs this with independent laboratory testing.
- Works 24 hours a day, 7 days a week
- Built into every HealthProtect model

Clean air to every corner of the room
Most purifiers push clean air in one direction. The SpiralAir outlets send it out through 360 degrees, so the whole room gets clean air quickly. Air is drawn in from the sides.
- Hidden wheels make it easy to move
- Adjustable cord winder keeps the cable tidy

See your air quality at a glance
The LCD display shows particle levels, VOC level, temperature and humidity, and how much filter life is left. In Auto mode the built-in sensors set the fan speed for you. The Blueair app adds a clean air countdown and works with Alexa.
- Child lock, night mode schedule and LED brightness in the app
- Speeds 1, 2, 3, Auto and Night

One filter, two layers
The SmartFilter has a particle layer and an active carbon layer, and Blueair says the carbon layer removes gas, odours, smoke and VOCs. The two filters fold over like a booklet when you take them out, so dust stays inside. A chip tracks use and the app tells you when to replace it.
- A genuine filter lasts 6 to 12 months
- Replacement filter Rs 18,000, in stock

Quiet enough for the bedroom
On its lowest speed it runs at 25 dB(A), about a whisper. Night mode can be scheduled from the app, and even the highest speed stays at 45 dB(A). On low it uses just 9 W.
- 25 dB(A) on low, 45 dB(A) on high
- Night mode runs on a schedule you set

Worked out at the highest fan speed, 8 hours a day. On Auto and the lower speeds it costs less.
