Updated October 25, 2026
All 3 expert reviewers tested it hands-on and agree it is a strong particle cleaner with a very high clean air delivery rate (300/320/300), but loud (about 59.5 dB at top speed) and power-hungry (about 76 W, roughly 1 kWh per day). Owners are more enthusiastic: 60% of 470 comments praise air quality, 539 of 676 star ratings are five stars, and only 6% mention failures. Noise is the clearest split: 26% of owners call it quiet versus 12% who complain about noise. The expert pool is small at 3 reviews, so confidence is medium.
What each expert concluded
A powerful, easy-to-use and affordable purifier that clears a medium room quickly, but it is loud, power-hungry and lacks features, so the reviewer finds it merely adequate and suggests alternatives like the Winix 5300-2 or Levoit Core 600S.

The no-fluff verdict
This is a simple, switch-it-on-and-forget-it purifier that clears the air in a big room fast and handles fine dust and pet dander well. The main catch is noise and power use: it has no quiet mode, no auto mode and no app. It suits people who want strong cleaning for the money and don't mind a fan sound in the background.
