How we evaluated it

How it scores Our rating, metric by metric Good, 4.1 of 5

Filtration 30% of the rating 4 of 5

AHAM lists a smoke CADR of 161 for a 250 sq ft room and HouseFresh measured 165 cfm, but the 99.97% HEPA figure rests on a lab Levoit does not name.
Adds nothing to the air 20% of the rating 5 of 5

CARB lists it as mechanical (order G-26-154) and Levoit lists no ionizer, UV or scent stage.
Independent testing 20% of the rating 4 of 5

HouseFresh, which takes no money from Levoit, measured its CADR and noise, but AHAM and CARB are certifications Levoit pays for and nobody has tested its HEPA claim in public.
Trust 10% of the rating 3 of 5

Vesync is settling a class action over HEPA wording on older Levoit models and stopped making certain HEPA claims in 2023 after a Dyson challenge; the Eleva is not named in either.
Running cost & value 20% of the rating 4 of 5

At about $130 it costs about $0.81 per CFM of CADR, but filters run about $60 a year (HEPA $39.99 every 2 years, carbon $19.99 to $34.99 every 6 to 12 months).

The rating, 4.1 of 5, is the weighted average of these scores. See how we rank air purifiers and our standard.

What it’s made of What touches your food, water, skin or air 3 materials

Particle filter: pleated HEPA media with a pre-filter layer (what the media is made of is not stated)
Gas filter: activated carbon pellets in a separate cartridge, sold in four types (HouseFresh puts the Premium at about 260 g of carbon; the others are not stated)
Plastic housing, fan and circuit board (resin types not stated); no ionizer, UV or scent stage listed

Who tested it What each test found, and who paid for it 4 tests

Independent HouseFresh (buys its test units; earns affiliate income and lists a Levoit discount code) October 22, 2026

Measured a PM1 CADR of 165 cfm at top speed with incense smoke in a 728 cubic foot room, 55.4 dBA at turbo from 3 ft and 23.9 W at top speed, and ranked it its best small-room pick. Open ↗ (opens in a new tab)
Paid certification AHAM Verifide (certification; Levoit pays)

Smoke CADR 161, dust 161, pollen 172 for a 250 sq ft room, 145 kWh a year. It tests how fast the machine clears smoke, dust and pollen, not gases, ozone, noise or wear. Open ↗ (opens in a new tab)
Paid certification CARB (certification; Levoit pays the lab) June 30, 2026

Listed as Mechanical (order G-26-154), so it passed the state’s ozone limit. It says nothing about particle removal. Open ↗ (opens in a new tab)
Maker’s own test Levoit (maker)

Says the filter captures 99.97% of 0.3 µm particles “based on ASTM F3150-18 test standard, based on independent third-party testing”. It names no lab and publishes no report. Open ↗ (opens in a new tab)

Who paid, and why it matters

Independent The tester took no money from the maker for it: a consumer group, a journalist, a university or a regulator.
Paid certification An outside lab or certifier tested or listed it, and the maker paid for that.
Maker’s own test A lab report or certificate of analysis the maker commissioned and published.

A certification is a floor, not a verdict: it checks what its program checks and nothing else. We weigh tests by someone with no stake in the result most.

What people ask Worries raised online and elsewhere, and what we found 4 questions

Is Levoit’s HEPA claim honest? Its maker was sued over it.: Sen v. Vesync (opens in a new tab) (Kings County Supreme Court, No. 510627/2026) says “True HEPA”, “HEPA” and “H13” claims on Levoit Core and EverestAir purifiers sold from 2019-08-29 to 2023-08-04 were misleading. Vesync denies it and has agreed to a settlement of up to $15 million, with a fairness hearing set for 2027-02-17 (opens in a new tab). In 2023 Vesync also stopped using the claims (opens in a new tab) after Dyson challenged them at BBB National Programs; the case was not decided on its merits. The Eleva is not named in either. Its own page cites ASTM F3150-18 and an unnamed lab, and HouseFresh (opens in a new tab) says the Eleva filters have been certified HEPA grade without citing a report.
Does the filter contain PFAS? Some HEPA media uses PTFE.: Levoit does not say what its HEPA media or housing is made of, and we found no published PFAS test of purifier filter media from any maker. We could not confirm either way.
Is it loud, power-hungry or costly to keep?: HouseFresh (opens in a new tab) called it the best value among small purifiers per unit of CADR, but power-hungry at top speed and pricey in filters compared with other small units. We count about $60 a year for filters.
Do you need the app, and what does “AI” add?: HouseFresh says you must register the filters in the VeSync app to keep filter-life tracking, and that the AI reporting adds lag with no clear benefit. We did not review VeSync’s privacy policy.

Why we chose it What put it on our list 5 points

AHAM’s directory lists the LAP-C341S-WUSZ at a smoke CADR of 161 (dust 161, pollen 172) for a 250 sq ft room, at 145 kWh a year. Our two-thirds rule gives about 240 sq ft. HouseFresh, which buys what it tests, measured a PM1 CADR of 165 cfm.
CARB lists the model as Mechanical (notified 2026-06-30, order G-26-154). By CARB’s definition that means filtration only, with no ozone or ions.
The particle filter and the carbon filter are separate cartridges, so each is changed when it is spent.
Filter prices and schedule are published: HEPA filter $39.99, rated up to 2 years; carbon filters $19.99 to $34.99, rated 6 to 12 months.
Levoit rates it at 20 dB in sleep mode and 50 dB at the top speed; HouseFresh measured 55.4 dBA at turbo from 3 ft.

Trade-offs What to weigh before you buy 4 points

The 99.97% HEPA figure rests on “independent third-party testing” that Levoit does not name. Levoit’s maker, Vesync, is settling a New York class action (Sen v. Vesync) over “HEPA” and “H13” wording on older Core and EverestAir models, and stopped making certain HEPA claims in 2023 after Dyson challenged them. Neither case names the Eleva.
Levoit does not say how much carbon its carbon filters hold; HouseFresh puts the Premium filter at 260 g. Carbon filters are changed every 6 to 12 months, so filters cost about $60 a year.
It is new: CARB first listed it on 2026-06-30 and Amazon lists it as first available on 2026-07-10. RTINGS is testing it, but its results are for members only.
HouseFresh found it power-hungry at top speed (23.9 W) and notes you must register the filters in the app or lose filter-life tracking. Rooms above about 240 sq ft need a bigger model.

What to know Details worth knowing first

The Eleva 300X is a small cylinder with a particle filter, a separate carbon filter and a four-speed fan. That is the design our air purifier guide points to: a HEPA filter does the work on fine particles, and the machine adds nothing to your air.

What sets it apart at this price is evidence other people hold. CARB’s list carries the exact model number as a mechanical cleaner, AHAM’s directory carries its CADR, and HouseFresh, which buys what it tests, measured 165 cfm, close to AHAM’s 161. Size your room by that number: about 240 sq ft.

Two cautions. The HEPA figure is Levoit’s own, and the company is settling a class action over HEPA wording on older models. And a particle filter does not remove gases: see indoor pollutants, and our look at whether purifiers improve health. Count on about $60 a year for filters, and change them on schedule.

What we checked Each claim, and how sure we are of it 5 checks

How Levoit Eleva 300X Air Purifier measures up against our air purifiers criteria
What we checked	What we found
True HEPA Maker’s claim	Levoit says it captures 99.97% of 0.3 µm particles, “based on ASTM F3150-18 test standard, based on independent third-party testing”. It does not name the lab, and we found no report.
No ozone (CARB listing) Verified	CARB’s list has Levoit LAP-C341S-WUSZ as type Mechanical, notified 2026-06-30, order G-26-154. The product page mentions no ionizer, plasma or UV stage.
Right size (CADR) Verified	AHAM’s directory lists LAP-C341S-WUSZ (Eleva 300X): room size 250 sq ft; smoke, dust and PM2.5 CADR 161; pollen 172. HouseFresh measured 165 cfm. Our two-thirds rule: about 240 sq ft.
Carbon for gases Maker’s claim	A replaceable activated carbon filter ships with it, and Levoit sells four types ($19.99 to $34.99). The amount of carbon is not stated for the standard filter.
Running cost and noise Maker’s claim	HEPA filter $39.99, up to 2 years (tested to a 50% fall in CADR at 12 hours a day on the top speed); carbon filter 6 to 12 months. 20 to 50 dB per Levoit; HouseFresh measured 35.8 to 55.4 dBA.

What the labels mean

Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
