Filtration Technology

The HFD-120-Q uses a 3-stage filtration system: a washable pre-filter catches large particles like pet hair and dust, the True HEPA filter captures 99.97% of particles as small as 0.3 microns (pollen, mold spores, dust mite debris), and the activated carbon filter absorbs odors, smoke, and VOCs. The permanent washable filter design is relatively uncommon among True HEPA purifiers and sets this model apart from competitors that require filter replacements every 6-12 months.

CADR & Sound

Noise & Performance

The purifier covers rooms up to 170 sq ft with approximately 4.8 air changes per hour, meaning the entire room's air passes through the filters nearly 5 times every hour. The noise level sits at 45 dB across its 3 speed settings, which is roughly equivalent to a quiet library or soft background hum.

For bedroom use, this is adequate for most sleepers but notably louder than premium purifiers that offer sub-30 dB sleep modes.
