Our verdict

The Core 300 is the plain sibling of the Core 300S: the same 36 cm cylinder and filters, but no sensor, auto mode or app. You pick speed I, II or III or sleep mode, set a timer of two to eight hours, and turn the display off or lock it. Levoit’s UK manual gives a CADR of 187 m³/h, with no test standard named; by our five-air-changes rule that suits a room of about 15 m², while Levoit’s 40 m² assumes two air changes an hour.

Its strength is the filter choice: the Core 300-RF original, pet allergy and toxin absorber cartridges all fit. Levoit says to change them every six to eight months, and the check-filter light is a running-time reminder. It is frugal, at 33 W on top speed, about 0.26 kWh over eight hours, and under 0.5 W on standby. Levoit says its purifiers use no ioniser or UV light.

It suits a bedside table or small home office where you’re happy to set the speed yourself; our best air purifiers for bedrooms covers the alternatives. If you would rather it reacted to the air, the Winix T500 WiFi adds a sensor and an app.

Living with it

Of the 27 owner reviews we read, 16 on Levoit’s UK store, which shows only four- and five-star reviews, and 11 on eBay UK, five call it quiet in use, and three single out how quiet sleep mode is or that the display goes fully dark. Three find it solidly made and three like the simple controls and timer, one because it has no Wi-Fi. On the other side, one owner felt it removed little pollution, and another found it took about two hours to clear dust and thought the filter no better than their old one.

Levoit Core 300 questions

Does the Levoit Core 300 have an auto mode or air-quality sensor?

No. You choose speed I, II or III or sleep mode yourself, and the timer switches it off after two, four, six or eight hours. If you want a purifier that speeds up when the air gets worse, the Core 300S has a laser dust sensor, auto modes and an app, and takes the same filters.

Do the Levoit Core 300 and Core 300S use the same filter?

Yes. Both take the Core 300-RF family: the original three-stage filter, the pet allergy version with a stronger carbon layer for pet and cooking smells, and the toxin absorber for smoke, fumes and VOCs. Levoit says to change any of them every six to eight months, and that its filter tracking is designed around genuine Levoit filters.

How do I reset the filter light on a Levoit Core 300?

After fitting a new filter, hold the check-filter button for three seconds until the light goes out. If you changed the filter before the light came on, hold the button for three seconds to light it, then for three seconds again to reset it. The filter sits in the base: flip the purifier and twist the cover anticlockwise.

Can I turn the lights off on a Levoit Core 300 at night?

Yes. The display off button turns the lights off, and display lock stops the settings being changed by accident. Sleep mode is its quietest setting, rated at 24 dB in Levoit’s UK manual. Leave 38 cm of space on all sides so it can draw in air freely, even on a bedside table.

Why does my Levoit Core 300 smell?

Levoit points to three causes: a dirty filter, very humid air or essential oils being diffused nearby. Clean the pre-filter, replace the filter if it is due, and keep diffusers away. Brush or vacuum the pre-filter every two to four weeks; don’t wash it, and don’t try to clean the main or carbon layers.
