Levoit Core 300S vs Levoit Core 200S
Quick take: The Levoit Core 200S costs $20 less; the Levoit Core 300S moves more air (141 CADR, 57% more cleaning power); the Levoit Core 300S has a particle sensor with auto mode, so it actually responds to cooking smoke and pollen spikes on its own.

| Maintenance | The filter is a single 3-in-1 cylinder that twists out of the bottom in under a minute. Vacuum the outer pre-filter mesh every 2-4 weeks to stretch filter life toward the 8-month mark. The laser PM2.5 sensor behind the side door needs a gentle swab every couple of months or auto mode starts lying to you. Levoit sells color-coded specialty filters (pet, toxin, smoke) at higher prices, but the standard Core 300-RF fits and third-party filters work without any DRM lockout. | Same twist-off bottom filter access as the rest of the Core line - swap takes a minute. Vacuum the pre-filter mesh monthly; the filter light is a simple 6-month timer you reset manually. There is no air quality sensor to clean because there isn't one. Genuine Core 200S-RF filters run about $26, and third-party 2-packs cost less than one genuine filter with no lockout. |
