Blueair 3250i Air Purifier, White/Grey

Only Blueair air purifiers use HEPASilent™ dual filtration, delivering more clean air faster¹ and using less noise² and energy than HEPA filtration alone. Purifies up to 48m2 living space in 30 minutes or 20m2 in 12.5 minutes on high.

Removes at least 99.97% of tiny airborne particles like viruses and smoke down to 0.1 microns, and captures pet dander, pollen, mould and dust. The activated carbon filter traps light household odours from smoking, pets and cooking.³

Seamlessly connect to the Blueair app to control and schedule your purifier, monitor your air quality and more. The Welcome Home feature automatically sets your purifier on standby when you leave home. Compatible with Amazon Alexa and Google Assistant for Wi-Fi enabled voice commands to control your Blue 3250i.

Quieter than a whisper at only 18 dB on low fan speed. The Blue range are certified by Quiet Mark as one of the quietest air purifiers, perfect for use in your bedroom for a good nights sleep. The intuitive display has an easy to read 5 colour air quality indicator and filter change reminder, while the two-button design lets you easily control 4 speeds, select auto or night mode, adjust light levels and enable child lock.

Blue 3250i uses as little as 2.5W – 20W of energy, depending on fan speed setting, which is less than an incandescent lightbulb. Blueair's RealTrack app technology accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.

¹Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs the same models with only H13 HEPA mechanical filtration.

²When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration.

³Tested PM 2.5 (0.1 - 2.5 microns) up to 90min in a 30m3 room. Tested to remove min. 99.9% of S. aureus, K. pneumoniae, P. aeruginosa, MS2, E.Coli, H1N1, A.Niger.
