"I set up three in my apartment and I never had to dust again."
"My partner has a severe dust mite allergy and the first thing we bought was a a Levoit true HEPA filter air purifier. ... A combination of both have made a night and day difference, we noticed the different straight away"
"I have 4 parrots 2 of them being African Grey’s and these suck the powder down as well as everything else out of the air. ... These make such a difference in air quality and dust control it’s unbelievable."

"It honestly changed my life. ... I used to literally cough up blood due to the irritation from seasonal allergies. When I’d lay down at night you could hear burbling in my lungs. I got this filter last summer and it was legitimately the first summer I’ve slept well in close to 20 years. ... Ditto this summer. I’d say a 90% reduction in my symptoms while at home."

"They do a good job of removing smoke from the room."
"never had any issues with odor! ... Helps for dust as well."
"We use the 300 in our living room which is a decent size and open floor plan with our dining room and kitchen, both large spaces and the 300 does great! ... We’ve asked our guests if there’s any pet smells and they always say no. ... We keep our 300 purifier within 6ft of the dog kennels too to help with residual funk from them."

"Best bang for your buck for sure. Coway Airmega 400 has the same CADR and costs 2x as much for example."

"I’m using levoit filters at home and they’re fine and the 2.5 levels are very low. I can also connect them to home assistant which is a big plus for me so I can monitor the filter level(though I’m guessing this is just an arbitrary use based calculation). But I do regret buying them due to the replacement thing."
"the levoit filters were expensive to replace."
"They just wear out their filters sooner."

"At times I wish I'd sprung for the Coway Airmega due to the higher CFM."
"the Levoit 300 is probably fine for a bathroom type space, but it is generally undersized for most rooms."
Nomski88 1.0Levoit 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.
unforgettableid 1.0Hello! Out of those two, definitely choose the Levoit. Small Chinese manufacturers may use various sneaky tricks to artificially boost their review scores. If their average scores drop, they might choose a new random brand name (e.g. ZKLX) and start over. ### Deals If you don't want to spend $120, consider looking for a name-brand unit which is used, refurbished, open-box, or an [Amazon Resale](https://www.amazon.com/b?node=10158976011) item. Maybe try Facebook Marketplace or your favorite classifieds app. You can also post a wanted ad to /r/purifiers_classifieds. Amazon Resale makes it easy to buy, and offers easy returns if you don't like the purifier. However, it's probably even cheaper to buy used locally. ### Sensors > AQ read‑out The air quality sensor built into any consumer-grade air purifier will likely be cheap and unreliable.
aoike_ 0.7Ive got pets and asthma, and I think the air purifiers help. At the very least, they do trap a lot of dust and pet dander. I also find the noise soothing. I've got a lenvoit that my mom bought me from Home Depot. Neat thing. Does a space of about 300 sqft. Filters are easy to replace, and the machine is easy to keep clean.
Fragrant-Gain1081 0.4i bought a plasma pro one the other day. as long as i keep it off, do you think it’ll be fine?
JAK49 0.4I’m using a few Levoit Plasma Pro units. It honestly changed my life. I used to literally cough up blood due to the irritation from seasonal allergies. When I’d lay down at night you could hear burbling in my lungs. I got this filter last summer and it was legitimately the first summer I’ve slept well in close to 20 years. Ditto this summer. I’d say a 90% reduction in my symptoms while at home. Obviously outside the house I still get nailed. I burn through filters though. I run this thing on max most of the summer. The rest of the year I set it to auto and let the sensors detect when to ramp up. Not sure exactly how the air quality sensors work, but they are extremely fast and accurate. If I have a candle lit they go crazy letting me know my air quality is terrible.
NeitherSparky 0.4Some Levoits do have an ionizer function. :P The ones you buy in the big box stores tend to have it, on the box it will say “PlasmaPro”. I bought a model on Amazon that does NOT have the PlasmaPro function. Now, probably, you can just not turn on PlasmaPro and it’s fine but I wasn’t taking any chances.
I literally do not know. When I asked the company the same question they just denied that ionization can harm birds. I returned the PlasmaPro model I had bought at Target and ordered one without from Amazon, I didn’t want to take any chances.
5yleop1m 0.3https://www.amazon.com/Xiaomi-Purifiers-Efficiency-Intelligent-Purifier/dp/B08LH7XZ3H. This one but the amazon listing isn't available anymore. I think the new ones also support it. Also I believe have different devices available for different regions. I also have a Levoit purifier but that one requires a cloud connection to integration with HA, no local options afaik.
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.
Carpie_L 0.3I 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

I've had 3 Levoit 300s for over 2years now and they are all still working brilliantly. and with a lot of entity exposure to HA
I found that the smart features is where it’s really excelled. the particular sensor allowed for variation in speed ‘of the fan’ which meant that it wasn’t working at 100% all the time and picked up when the PM2.5 sensor detected an increase in impurities. Aside from that I have other PM2.5 senses around the house that can also increase the fan speed when required through voice assistant automations. Where you can also issue voice command automations like I am cooking.
detterence 0.3Get the Levoit 300S model, it’s clean way more square footage (900-1000) at the same wattage as the 200S model. It’s literally the perfect balance of cleaning as much area as possible with also keeping your electricity bill low.
Levoit is good for the price.
