Updated October 25, 2026
All 4 hands-on reviewers praise the main HEPA filter's five-to-six-year lifespan and washable pre-filters, and 61% of 457 owner comments say it noticeably improves air quality, with 30% calling it quiet. The recurring drawbacks are consistent: all 4 reviewers note there is no app and no included remote, 3 of 4 say it gets loud at higher speeds, and 3 of 4 found the odor cartridge ineffective or overpowering. Sensor accuracy is a real question, raised by one reviewer and 7% of owners, while only 3% of owners report a unit failing. Evidence on actual filter replacement cost is thin, with just one source citing about $90 every five years, and the scent cartridge price is not stated anywhere.
What each expert concluded
A solid mid-range purifier with a very long-lasting filter and good fine-particle capture that suits pet owners and medium rooms, but it is noisy at higher speeds, lacks remote or app control, and its scent cartridge can be overpowering.
Hands-on review · open the review ↗~8/10A quiet, effective, low-maintenance purifier for large rooms whose five-year main filter cuts upkeep costs, held back mainly by its bulk and a few omissions like a bundled remote and smart features.
Hands-on review · open the review ↗A large, data-rich purifier with a six-year HEPA filter and washable pre-filters that cleans quickly and is good value, held back by a bulky look, a side-mounted display, and no remote or app control.
Hands-on review · open the review ↗3/5A quiet, easy-to-use purifier with a long-life HEPA filter that helped the writer's overnight breathing, but its sensor reads too optimistically, making Auto mode unreliable, and it did nothing for cooking smells.

The short version
This is a large, set-and-forget purifier that cleans a room quickly, stays quiet on its lower speeds, and goes years before its main filter needs replacing. Its biggest strength is low upkeep, since you just rinse the outer filters now and then. The catches are its bulk, noise on the top speeds, no app or included remote, and a scent cartridge that may not do much for smells. It suits pet homes and larger rooms where you want clean air without fuss.
