Best thing: Very quiet low and Sleep Mode settings
Honest catch: Not meant for large open-plan rooms — in 1,066 ft² it manages only one air change per hour
For a bedroom, study or home office, the Core 300-P is the sensible buy: a maker-stated 143 CFM CADR, a main filter rated at 99.97% and a sleep-friendly 24 dB low setting, all on an 8.7 × 8.7 in footprint. The trade-off is reach and smarts — it is not built for big open-plan spaces, and there is no app; that is the Core 300S-P.
Sleep through it: QuietKEAP technology brings noise down to as low as 24 dB, and Levoit rates Sleep Mode at 26 dB or less.
Sized for real bedrooms — Levoit rates it to change the air in a 222 ft² room 4.8 times an hour.
Targets everyday allergy triggers: the 3-stage filter traps fine dust, smoke particles, pollen and pet dander, with a main filter rated at 99.97% down to 0.3 μm.
Activated carbon helps with cooking smells, pet odors and VOCs, not just dust.
Set it and forget it: a 2–8 hour timer, plus a check-filter indicator that tells you when to swap the filter (Levoit suggests every 6–8 months).
Ozone-free and CARB compliant — nothing to second-guess in the room you sleep in.

Levoit rates it for 222 ft² at 4.8 air changes per hour, or 1,066 ft² at one air change per hour. For noticeably cleaner air, size it by the smaller figure.
Levoit recommends every 6–8 months, and the check-filter indicator reminds you. Besides the Original Filter, Levoit offers Pet Allergy, Toxin Absorber and Smoke Remover versions.
No. The Core 300-P uses touch buttons on the unit; the app-connected version is the Core 300S-P.
