What to know before buying
Listing details to confirm
The listing gives conflicting filtration claims: one section says 99.999% reduction of 0.01-micron particles, while another says 99.97% of 0.3-micron particles. Coverage figures also vary, including 361 sq. ft. in 12.5 minutes, 874 sq. ft. in 30 minutes and 1,748 sq. ft. in 60 minutes. These are listing claims, not independently established performance. Confirm the applicable coverage and filtration specifications for your needs. The listed 53.8 db noise value also differs slightly from the feature text's 24 dB to 53 dB range.
