Levoit Vital 100S-P Review

The bedroom pick: in the AHAM Verifide directory with a 143 / 161 / 173 CFM per-pollutant CADR, a stated 99.97% capture at 0.1–0.3 microns, 25 dB sleep mode, and the air-change rate stated rather than implied.

  • AHAM directory: smoke 143 / dust 161 / pollen 173 CFM, 222 sq ft
  • 99.97% stated capture of particles from 0.1 to 0.3 μm
  • 25 dB sleep mode with automatic display dimming

Best for: Bedrooms and small rooms up to about 222 sq ft · Specifications last checked September 24, 2026

Overview

Two things make the Vital 100S-P the model we would put in a bedroom. The first is that its filtration efficiency is stated with a particle size attached: 99.97% capture of particles between 0.1 and 0.3 micrometres, which is the range that includes pollen, smoke particles and the fine fraction of dust. A generic HEPA badge is not the same claim — this is a testable statement, and the machine appears in AHAM's certified directory with a CADR listed separately for smoke, dust and pollen.

The second is that the coverage claim comes with a rate rather than only a room size — and here the claimed figure and the certified one agree exactly. Levoit states the unit can purify the air 4.8 times per hour in rooms up to 222 square feet, and AHAM's directory lists 222 square feet for the same model. That agreement is rarer than it should be: the larger Vital in this comparison carries a 1,875 sq ft claim that AHAM lists at 388. Publishing the air-change rate alongside the area is what makes the number checkable, and it lets you reason about a slightly larger space, where you simply accept fewer changes per hour.

For overnight use it runs at 25 dB in sleep mode and dims its display automatically when the room gets dark, which is a small thing that decides whether a purifier stays switched on. There is a washable pre-filter, a three-stage filtration system, and scheduling so you can set fan speed or a mode like Pet Mode for specific periods. The limitation is simply size: this is a bedroom machine, and buying it for a living room would be a mistake.

More angles

More from the manufacturer's product listing. These include the brand's own annotated graphics as well as plain product shots. We reproduce them unaltered, so any performance figure printed inside an image is the manufacturer's claim — it is not a measurement of ours, and it is not why a model ranks where it does here.

Pros

  • In the AHAM directory with a full per-pollutant CADR plus a specific particle-size efficiency claim
  • The claimed 222 sq ft matches the AHAM directory figure exactly — the only coverage claim here that does
  • 25 dB sleep mode with automatic display dimming suits bedrooms
  • Washable pre-filter reduces main-filter running costs
  • Per-period scheduling and a dedicated Pet Mode
  • Owner rating of 4.7 across a very large review base

Cons

  • 222 sq ft is a bedroom-scale certified figure — it will not service a large living room
  • Smaller filter volume means more frequent replacement than the larger model

Who it's for

  • Bedrooms and small rooms where noise and light matter overnight
  • Allergy sufferers who want a testable filtration claim rather than a badge
  • Pet owners who want a dedicated Pet Mode and a washable pre-filter

Who should skip it

  • Open-plan or large rooms, which need the bigger model
  • Buyers who need more than 222 sq ft of certified coverage from one unit
  • Anyone who wants one purifier to cover an entire apartment
