Medify Air MA-14 Air Purifier vs FRESHDEW HEPA Air Purifier AP401

The FRESHDEW AP401 is the stronger purifier for real rooms: much higher CADR, 360° intake, a PM2.5 display, a 1–12 hour timer and a 3-year warranty. The MA-14 is a small tabletop unit with a nightlight and a 1-hour timer, fine for a bedroom or desk but limited to roughly 200 sq ft. Owners rate both highly, though the FRESHDEW's 4.9 comes from far fewer ratings, so treat it as promising rather than proven.

• Choose the MA-14 if you want a compact, light tabletop purifier with a nightlight for a small bedroom or office.
• Choose the FRESHDEW AP401 if you need to clean a large room, want quiet sleep operation and a longer warranty.
