Overview
The LEVOIT Core 400S-P is a HEPA air purifier rated for rooms up to 1,733 sq ft in an hour of runtime, built around a 3-in-1 filter and AHAM-tested CADR numbers for smoke, dust and pollen.
Rather than lean on a vague square footage claim alone, the listing cites specific AHAM VERIFIDE CADR figures: smoke 231 CFM, dust 240 CFM, pollen 259 CFM, numbers checked by an outside testing body rather than the brand itself. A laser dust sensor also drives a live PM2.5 readout, so the room's actual air quality is visible rather than assumed.
- AHAM VERIFIDE certified CADR: smoke 231, dust 240, pollen 259 CFM
- Covers rooms up to 1,733 sq ft per hour
- 3-in-1 filter rated 99.97% for 0.1-0.3 micron particles
- Laser sensor with live PM2.5 display, sleep mode, child lock
Who it's for
Fits large bedrooms or open living spaces dealing with pet dander, smoke or dust. Overkill for a small room, where a smaller Core model would cover the space for less.
Pros and cons
- AHAM-tested CADR ratings back the coverage claim
- Rated for rooms up to 1,733 sq ft
- Laser sensor drives a live PM2.5 display
- Sleep mode and child lock included
- Large coverage area is more than a small room needs
- Filter replacement cost is not covered in this listing
Performance notes
The 3-in-1 filter targets particles down to 0.1-0.3 microns at a 99.97 percent rate per independent lab testing, while a laser dust sensor continuously reads the surrounding air and feeds the PM2.5 display so Auto Mode can adjust fan speed to actual conditions rather than a fixed schedule. Sleep Mode and Child Lock cover nighttime and household use.
