Levoit Core 300S

Based on 84 comments across 2 communities
TL;DR
Owners overwhelmingly like the Core 300S for visibly cutting down dust, pet hair, and cooking or smoke odors, and many praise how quiet it runs in auto and night modes for the price. The biggest gripes are pricey replacement filters and a built-in air-quality sensor several owners find unreliable, with a handful reporting weak performance or motor noise. It's a strong, budget-friendly pick for small rooms, but expect it to struggle in larger spaces.

68% of 84 verified owners recommend the Levoit Core 300S.

We have two of the Levoit Core 300S, and in the last year, we had had both replaced under warranty. Both had their motors fail. They first started making a squealing noise, which got louder and louder. First failed within 30 days, second after six months.

Levoit Core 300s can lower a PM of around 70 to 10 in 12m2 room for 60minutes of running on max fan speed. I test that regularly in my cigar room 😂

I like the Levoit Core 300s due to simplicity of changing the filter, but they are less performant and most costly if you buy the authentic purifier replacements.

I bought two Coway AP-1512HH and 4 Levoit Core 300s to cover the majority of my house. They've made a noticeable improvement in my allergies! I don't think they really cut down on dust much

We went with the Levoit Core 300s can be controlled by wifi/app. So far it’s been great. It also has a nice “lock” feature to keep the controls from being manipulated by curious little hands.

The air purifiers regularly reads a “1” especially when it’s on (understandably), but when I open the door to let particulates in the reading hardly changes while the independent sensors do.

I had a levoit Core300S but this would require changing the filter every 3 weeks as it would get totally saturated in E juice , which would mean a £30 bill every 3 weeks just for filter , not viable

I have two Levoits, a Core 300s in the bedroom and a larger one in the living room. Filter has lasted 4 months with running it 24/7 and cost $25 to replace from Amazon

Then I decided on more well-known went for Levoit Core 300s. I could tolerate the Levoit a substantial bit more, but I felt it still unacceptable.

I have to replace the greenish filter from Levoit Core 300S after 3 months because it starts to stink when I turn it on.

I have a couple of Levoit Core 300s and they make my apartment noticeably less dusty and cat hair-y, and I think they help with cooking smells.

I have two Levoit Core 300s and have been very happy with them! Dust accumulates where the air is pulled in and you can see what has been pulled from the air when you change the filter. I feel like it does help with allergens.

We also have a Levoit Core 300s that used to be in our bedroom but we moved that to another room as I like the washable prefilter of the Vital 100s better.

Es gibt auf Amazon so billig Dinger wie z.B. Levoit Core 300s, die sind aber extrem scheiße und bringen gar nichts! (Spreche aus Erfahrung)

I use a Levoit Core 300S to help cut down on the fume spread. This model provides PM2.5 monitoring which in combination with your nose, helps to get an idea of the air quality in the space.

I originally had a Levoit Core 300s, and find the Starkvind works a lot better to filter air (and filters are less than half the price).

I use the Levoit Core 300S (or something like that, it's on Amazon). It only contains one filter that does it all, although the filters are pretty pricey.

I have a Core 400S, and two Core 300s. They all make the same annoying motor noise.

na zápachy třeba po vaření a tak je to super, ale co se týče prachu tak moc nevím, nedávno jsem čistil filtr a přišlo mi, že na něm skoro nic není

I have the levoit core 300s. no clue on whether it's actually good or bad, but it has no ionizer, price is decent, and the smart mode is very nice -- it automatically runs faster when mom burns something in the kitchen.

I personally have a levoit core 300S and it does a good job at getting rid of smells and overall making the air cleaner.

I recently purchased the Levoit core 300s also. I have an old Philips air purifier also. I noticed that the Levoit does not detect any change in the air compared to my Philips one. In the same room, dust and smoke, the Philips detects the air pollutants and changes it's icon to red. However, the Levoit doesn't detect any change in the air.

skúsil som levoit core 300s smart. Je populárny aj vo svete na rozdiel od toho druhého a má aj kopec reviews. Osobná skúsenosť zatiaľ v pohode
