I have two core 300 and I am happy with them! I want to get another for the room that the cat box is in. When I put the core 300 on high it really works well. I will say that on low or medium I don’t see much improvement(as far as smells go). I only run it on high for a few hours when we’re not around because it’s too loud for me. I am not sure how that compares to the one you have.

Buy [this](https://x.com/BestDealsxx/status/1965030549237752044) one if you can go to this price Definitely worth the money and lovely looking, compact but sizeable filter section; I have had other brands but this is superb Quiet in running, economical and very easy to change the filters (which are not cheap but they only need changing every 6-8 months - others are much sooner) Clears smells and vaping smoke well, also cat dust and fur from the air so perfect for my needs

So far, it doesn't feel like it's doing anything for the bedroom, and I've had it a few days.ive actually been waking up itchier than when I did not have it in the room. It does not have a hepa filter. Amazon tricked me as well. There's a whole scandal about Levoit advertising as hepa when they are not https://levoit.com/products/core300-p-air-purifier?srsltid=AfmBOoqK509UC81aTdqXBCIyTOz3_VaAnSjaBC8ecGykAdQcqVQs6SjE

I recently purchased 3 different levoit air purifiers from Amazon for my mom's place and they were all horrible. Ive been testing them out for about a month. My allergies became worse. They were also advertising as a true hepa when they are not and they are being sued for that. I went and ordered the classic Alen air purifier I have at my place for her, and it's so much better. I also ordered the refurbished flex that they had on sale for $99 for her bedroom. What a difference! Im returning all of the levoit air purifiers. Personally, Alen is a winner in my books

Same exact experience for me on the core 300 I just picked up. Good unit so far, but is def a little loud on low compared to my winix 555

Some 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.

FYI HEPA filters are basically marketing BS in the consumer world. Very few filters with "HEPA" in their description are actually capable of meeting HEPA standards. $400 for a 200sqft capable air purifier is crazy. I have a Levoit core-300 for my 100sq ft room and it clears out my vape smoke in a matter of seconds. I believe its possible to get activated charcoal filters for this to help reduce odor, if not you can find activated charcoal sheets or packets to put inside the air path. There's a community supported HA integration for Levoit, but its reliant on the cloud service. You can flash the Core 300 with ESPHome though and have it work completely locally. I also have a Xiaomi Air Purifier 3C, it also relies on a community maintained integration with Xiaomi Miot but it can work locally too, I know cause I have it blocked from internet access and it works fine. There is also a way to flash ESPHome on these, but I haven't tried. I'm using that one in my living room which is somewhere around 800 - 900 sqft but its a double height living room so there's a tremendous amount of volume there. Side note, make sure you've looked at fixing other parts of your house before getting an air purifier. Make sure your AC ducts are clean, and the filter for your AC is working properly. Though don't put a high MERV filter in there unless your air handler is designed for it. You can actually filter more without putting extra stress on your air handler with thicker filters, but in my experience its rare to see units that can hold the thicker filters without modification. Also make sure your windows are sealed properly.

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.

https://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.

I've lived in basement apartments for years and have always felt the air quality was poor so bought a couple air purifiers for my bedroom and main living area(Levoit Core 300). I definitely feel there's been an improvement. Then at work (old government building) I kept feeling like I was getting ill when I was in office, like the start of a cold but I would be fine the next day or while working from home. Bought a cheaper air purifier (Jafanda JF100) for there and now it doesn't happen. If it gets shut off I feel crappy within a few hours of being there.

Levoit air purifiers. You can get pet filters. I got a core 300 and it seems good
