LEVOIT Air Purifier for Bedroom Home, CADR 187 m³/h, 80m², with HEPA & Carbon Filters removes Pollen Allergies Dust Smoke, Air Cleaner with Timer, Quiet 24dB Sleep Mode, Core 300

Nearly 87,000 Amazon reviews. The Levoit Core 300 has a CADR of 187 m³/h and covers up to 80 m², which puts it somewhere between a small bedroom unit and the bigger whole-home machines.

Who is it for?

Bedrooms, home offices, medium-sized living rooms. If hay fever or pet allergies are your problem, the three-stage HEPA system handles pollen, dust mites, and pet dander. Levoit also sell swappable filters for different issues: pet allergy, toxin absorption, mould and bacteria. You pick whichever matches your situation.

Bigger open-plan space? You'll want something with a higher CADR. Our best air purifiers for large rooms guide covers options for 100 m²+ spaces.

Noise and sleep mode

24 dB on sleep mode. That's about a soft whisper. Most competitors at this price sit around 30-35 dB on their lowest setting, which is noticeably louder. We have a fuller comparison in our quiet air purifier for sleeping roundup.

The display light switches off in sleep mode too. Small thing, but it matters in a dark room.

Running costs

People forget about ongoing costs. Replacement filters cost around £20-£30 and last 6-8 months depending on how hard you run it. The unit draws about 45W on the highest setting, roughly £3-£4 a month if you run it 12 hours a day at current UK rates. More detail in our air purifier electricity cost guide.

HEPA filtration

True HEPA, H13 grade. Captures 99.97% of particles down to 0.3 microns: pollen, mould spores, dust, most bacteria. The activated carbon layer deals with cooking odours, pet smells, smoke.

This unit doesn't use UV-C or ionisers, so there's zero ozone output. Some cheaper purifiers produce trace ozone as a byproduct, which can irritate airways. Not a problem here. If you want the full picture on filter types, our HEPA filter air purifier article goes into it properly.

How it compares

Costs a fraction of what Dyson charges. Focuses purely on cleaning air rather than doubling as a fan. You lose app control and an air quality sensor on this model, though the Core 300S adds those. We compared both brands in our Dyson vs Levoit piece.

If allergies are the main reason you're looking, our best air purifier for allergies guide puts this alongside the Philips 3000i and Winix Zero-S.

Verdict

Does the job. Cleans air well, runs quietly, costs very little to keep going. No app, no smart features on this model. If you just want cleaner air in a bedroom or living room, that's what you get.

The swappable filter system is what separates it from most competitors at this price. You can optimise for allergies, pets, or mould rather than being stuck with whatever filter came in the box.
