Levoit Vital 100S Air Purifier Review
Bottom Line
Choose the Levoit Vital 100S for compact rooms, strong particle removal, quiet sleep use, and useful app controls. Skip it for large spaces, heavy odors, or exact PM2.5 readings.
Best for
Best for bedrooms, offices, pet-adjacent small rooms, and users who want a compact purifier with strong particle removal, sleep mode, scheduling, and app control.
Not for
Not for large rooms, severe odor or gas problems, buyers who need exact PM2.5 readings, or users especially sensitive to fan noise at higher speeds.
Verdict
The Levoit Vital 100S lands as a compact, smart purifier with unusually strong review support for small-room particle removal, bedroom use, app control, and easy maintenance. Its best evidence comes from measured air-quality gains, fast smoke clearing, quiet sleep operation, and repeated praise for VeSync, scheduling, and portability. The main tradeoff is capacity: reviewers liked it for bedrooms, offices, and modest spaces, but noted that larger rooms, heavy odors, serious gases, and exact PM2.5 data are not its strengths. Noise is also context-dependent, with most reviews finding it manageable while one owner found it loud.

-
VOC reduction was supported by reviewers who credited the purifier with handling VOCs alongside allergens, pollen, dust, and pet odors, though deep gas removal was not a strength.

-
Dust evidence was positive overall, from dust/allergen prevention claims to users seeing captured debris and improved effectiveness when dust was kept moving toward the purifier.
-
Sensor evidence was mostly positive for detecting obvious changes, smoke, and dust, though it was framed around general air-quality response rather than lab-grade accuracy.
-
CADR evidence was limited but positive, with one reviewer praising the purifier's noise optimization in light of its CADR-to-noise ratio.
-
Size and footprint were mostly strengths, with slim/compact design praised, although one user disliked the cold-air effect and another noted bigger devices may offer more value.
-
Filter availability was generally good thanks to third-party/generic and easy-to-find options, although one reviewer had trouble with an in-app purchase link.

Filter replacement cost was mixed: Levoit filters were called reasonably priced, but one reviewer disliked having to replace the whole HEPA/carbon assembly when carbon fills first.
