Levoit was the brand of choice for immunocompromised people during Covid. I have a Levoit 400S.

I had a winix 5520 for 1 week and a 400s levoit. The winix I could smell cigarette smoke my dad smokes in the basement, it was blowing out cigarette smoke smell on day 4. The 400s I bought doesn’t smell like that been running a month. I don’t smell cigarettes at all, I have unfortunately have to live here right now, and this what my setup is. Block off the main floor door. Put a curtain up over the door to help seal more. Have a levoit 300 core outside the door and the 400s inside my room. The 300 has taken a big hit and the carbon filter is done for already soaked up and just smells, so at this point i think it’s just taking all the toxic smoke out of the air but didn’t help the smell anymore unless I get a new filter. Ultimately if I had my own house I would get the winix. But I did notice that the vents are on the sides so you put it flush with the wall it’s not going to be as affective as the 400s.

Ho comprato levoit 400sdurante l'ultimo Black Friday e me ne sono pentito amaramente emette un odore che mi fa stare malissimo, ma Bastava leggere le recensioni, ovviamente sono poche perché nessuno vuole fare discussioni col venditore per poter fare il reso, ma ce ne sono molte e non dipende solo dall'odore del filtro. Ovviamente io sono più sensibile soprattutto ad un certo tipo di plastica ma non ho mai avuto nessun problema col Dyson

Just basic controls. This is with the 400s https://preview.redd.it/m0pmdj621crf1.png?width=1344&format=png&auto=webp&s=9cb7ace60a7e986c104e6a6837f3a69782c33046

I've got a Levoit 400S purifier and it does pretty well in Google Home. The controls in Google Home are the same as what's available in the VeSync (Levoit's parent company) app. Having the VeSync app installed also will give you alerts to filter life. The Google Home app doesn't seem to do that part.

Yeah, the purifier I have (Levoit 400S) says to vacuum the filter every 2 weeks.

I had the IKEA one got rid do it because I didn’t have space for 2. It was in my bedroom. It worked pretty well TBH. My other one is a levoit 400s for comparison.

I like the smoke filter with the 3 changeable pre-filters in the levoit. But I’ve had the 400s for 4-5 years it’s fine but when you change fan speeds it squeaks now after years of use. There’s no prefilter really unless you get that model. Well I guess there sort of is idk. Thinking about getting the 5520 Winix now Winix has a built in pre-filter easier to clean though I think.
