Choose Blueair Mini Restful Bedroom Air if…

It operates as quietly as 21 dB and uses medical-grade HEPASilent filtration. The USB-C port charges your phone overnight. However, it costs $112.99 and has a slightly lower rating. If you want a purifier that also helps you wake gently, this is your pick.
Our Verdict
Honeywell HPA125B Allergen Plus Compact
The Honeywell HPA125B is the winner for most people looking for a small-room air purifier. It delivers strong performance at a lower price, backed by a higher customer rating (4.5 stars from 334 reviews) and a better LAT score (86 vs 84). Its auto mode and quiet operation make it easy to use in a bedroom or office. While the Blueair Mini Restful offers innovative extras like a sunrise alarm and app control, those features come at a premium and don't improve core purification enough to outweigh the Honeywell's value. The Blueair's noise level is slightly lower (21 dB), but the Honeywell is already quiet on low settings. For a straightforward, reliable purifier that handles small spaces effectively, the Honeywell HPA125B is the smarter choice. If you prioritize a multifunctional sleep aid over pure value, the Blueair remains a solid alternative.
