Which One Is Right for You?

Choose Honeywell HPA125B Allergen Plus Compact if…

you want a straightforward, affordable HEPA purifier for a small room. The Honeywell HPA125B offers a higher customer rating (4.5 vs 4.4), more reviews, and a lower price ($99.99). Its auto mode adjusts fan speed based on air quality, and it runs quietly on low and sleep settings. It’s compact and lightweight, ideal for desks or nightstands. If you value proven performance and simplicity over extra features, this is the better value.

Choose Blueair Mini Restful Bedroom Air if…

you need a multifunctional bedroom device that does more than purify air. The Blueair Mini Restful combines a sunrise alarm, circadian lighting, and a mood light to support your sleep cycle. 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.
