Levoit series is good, I have the 300S Plasmapro and it's been great. Also uses a laser sensor for the air reading which is more accurate.

You need filters specially made for smoke, otherwise they will get fucked and start to smell of cigarettes , used my s300 levoit one day in a smoky room, now it smells like the room itself.

Is this model the ‘PlasmaPro’ unit? If so, the smell may be normal from ozone. Ozone gas is generated using very high voltage, and is used to help neutralize odors. If it’s not the plasma pro models, it may need to air out and will disappear after a while

https://github.com/acvigue/esphome-levoit-air-purifier There might be other similar projects online. I turned my Levoit 300s fully local using either that or a similar guide. I believe you can also do this with some Xiaomi air purifiers.

I have a Levoit 300 which can be flashed with ESPHome for full local control. You can find a GitHub link to the process in my profile/comments, just search "levoit". Should be there somewhere.

They should be the same, but I don't know 100%. I bought mine about 2 years ago.

Honestly I recently got a Levoit 300s cost about £130 on amazon & it is working brilliantly no more having to vape outdoors in the cold.

My room would probally be around 10m x 10m. The air purifier sits on the table where I vape and I tend to blow it towards the air purifier. I leave the unit on auto mode and to detects the air quality & automatically turns on and clears the "smoke". I would also vape 10-15 times a day in the room using a tiny might 2 & bong.

I second a Levoit. I have 3 different models right now in my house. They’re decent price and they last for years if you replace the filters on schedule. And I run my a few hours a day, sometimes all day. I have the core 300S and the 300S-P with WiFi in my living room and primary bedroom. I have LV-H128 in my kitchen. I used to have the LV-PUR131S but it finally died after 5 years
