Levoit - PlasmaPro 300S

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 asthma and allergies really bad from having 2 cats. I have 2 levoit 600 and 1 levoit 300. They will definitely help your asthma and allergies. Also talk to your doctor about a daily inhaler or an injection called dupixent. The dupixent is a complete game changer it completely alleviates allergies and asthma. For the cats I suggest getting them on liveclear from purina. My cats were sending me to the hospital every two weeks. I stopped taking the dupixent for a while and I'm super regretting it! I should be back on it in a week! I haven't been able to breathe in my house which has made sleeping a nightmare. So your not alone if this what your experiencing.

We have 2 Levoits, 400 in the family room and 300 in the bedroom. Happy with them.

Levoit 300 were great until they changed the manufacturing of their filters and now they give off a strong odour. Seems to be a common problem among air purifiers! I ended up going with a Northbox. They are housed with Merv 13 furnace filters, there’s no smell and it’s been the perfect solution for our home. I live in Canada…I believe the US equivalent is Clean Air Kits.

Get 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.

Hands down the coway, which is the wirecutter pick and works so great (we have two). Runner up is the Levoit 300, we have two of those as well. They are cheaper and not hepa certified but theoretically work pretty similarly, Levoit is a slightly more dodgy company. What do we use it for - covid prevention and air quality when cooking / generally.

We have 1x300s and 2x400s and they are working great 2 years in. VeSync app works well also.

My levoit 300s gives me sinus problems and sore throat. Piece of fuckin shit

I know!!!! Google air purifier sore throat reddit. You'll see. Levoit one of the worst offenders

Plus one for this. We use the same brand the 300S model in the bedroom and also the mini version in the room with the 3d printer. Only use the mini version thier as we have no space for the bigger version. Plus the mini version is super quite too!

For your purposes, the core 300s is perfectly fine, you’ll just need to replace the filters every two months or so. Vaping is murder on filters. I don’t think you’ll find a combination with a lower total cost of ownership.

Really interesting to see these mentioned. I grabbed a couple of these during the wildfires and they made a huge difference per my ppm monitor. It would read a few hundred ppm outside but would only be in the single digits in my room with the purifier on. But I bought a bigger one than recommended for the room so it could cycle the air on the room more frequently.

Luckily 500sq ft isn’t too big, so you can probably get something like the Levoit 300 for the main room and a smaller one for the bathroom. My advice is don’t get something too small for your main room, or it won’t work. And if you want serious air cleaning, then something large and rated for 2x or 3x your space size like a Levoit Everest or Coway Airmega 300 would really work well (and you’ll only need 1). Most purifiers will sell different types of filters, so check if they make a HEPA or pet filter for the model you want. Standard filters are just for general dust, but stronger filters like true HEPA work on pet dander, allergens, and smoke. And extra carbon filter helps with odor control, so that would be useful in the bathroom. But note that a lot of the stronger filters will emit a weird smell for the first couple of days, so let it run a while before anyone comes over.

Thanks for offering to answer questions. I have a few as well. I recently moved to a carpeted apartment and separately a new office. I have an extremely sensitive nose \[it is hard for me to spend time in a mall because of the various smells in the air\] and both are posing problems. 1) In the apartment, I can smell a sweet/rubbery smell from the carpet. Carpet is at least a year old, likely more. I open windows often - every few hours I ventilate. My Levoit 300s indicator light is blue and other than that the air quality is amazing - I live next to a nature reserve and about about 30m from a road that is rarely used - no cars outside of working hours and maybe 1 car every few minutes during the day. If I got an air purifier such as Winix 5500-2 or 5300-2 and changed the thin carbon filter every week with something like this, would that be sufficient? I would likely air out the room in which I spend the most time at least 2-3 times a day [https://www.amazon.co.uk/Pureburg-Purifiers-Accessories-Replacement-Replenishment/dp/B07PYDT9KR/ref=sr\_1\_1\_sspa?sr=8-1-spons&sp\_csd=d2lkZ2V0TmFtZT1zcF9hdGY](https://www.amazon.co.uk/Pureburg-Purifiers-Accessories-Replacement-Replenishment/dp/B07PYDT9KR/ref=sr_1_1_sspa?sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY) The interesting thing is that I feel the rubbery smell less when the room is warmer (which should be the opposite?) A last ditch scenario would be to cover the carpet with polyethylene and seal it all and then put cotton carpets on top. This is a rental and I am not allowed to replace the carpet with alternative flooring. Any other rental I could get would be in an area that has much higher outdoor pollution and would require me to commute - here I can walk to work. In the office I can feel an acrid smell and it comes from the walls. Paint is at least 7 years old, so not new. It irritates my throat slightly. I used to run my Levoit 300s here and it started releasing the same acrid smell - I assume because the carbon filter got saturated? Is that a thing? How can I address this? Would a washing the walls with vinegar or odorless detergent help? I have been airing the office for over a week with a large window open for 24 hrs each day. The carpet wash smell in the office has gone away with the airing but not the acrid smell/nose irritation. What solutions would you suggest? Thanks for your help!

I enjoy mine (Core 300s).

I just got a levoit 300s, it's pretty noisy on max setting. Have a browse of reviews: housefresh.com

i really like my levoit 300s, but it’s mostly for dust and pet hair. not sure about smoke.

I am currently running the house special of "I bought whatever was on sale at the time." So I have a mix of Levoit, Winix, Blueair, and a couple of decades old Honeywells to round it out. My AC system also has a "circulate" option and has a built-in HEPA filter and UV light. I monitor it all with a Airthings 2960 (one upstairs, one downstairs). Currently, I am trying to consolidate to a single brand (settled on Levoit - 300 and 600 sizes) just to make filter replacement simpler. Trying to get to a 6mo filter replacement schedule (currently closer to 4mo here in Texas, thanks to all the allergens). From my testing, here's the short version - as long as it moves air and has some sort of filtration, it'll probably help the air quality in your home. Everything else - air quality monitoring, app access, noise level - it's all bonus features that don't really affect the overall performance of the device. According to my Airthings AQ monitor, they do make a difference. I see VoCs and PM1 and PM2.5 go down when you ramp up the filter fan speeds. For recommendations - Level 1 - regularly change the air filter that your home uses - go cheap and replace more frequently rather than going expensive and hoping it lasts longer. Also, vacuum and dust regularly. Level 2 - bang-for-the-buck is the Corsi–Rosenthal box - and it will always be what I recommend to people who are trying to figure out if air filters will make a difference for them. Level 3 - buy the system that moves the most amount of air and has replacement filters that don't cost an arm and a leg. Levoit, Winix, Blueair, are all honestly decent systems - and if you open them up to replace their filters, you find out that they're really just doing the same thing the Corsi-Rosenthal is. They're just intake fans sitting on top of a filter. As price goes up, you're really just paying for things like automation (fan automatically ramping up when it senses high particles), noise reduction, filter change nagging, etc. My suggestion is to buy whatever goes on sale next time and stick with the brand/size for ease of maintenance. Minimum size I'd recommend is 1000sqft even if your home/room is smaller than that. The max room size is calculated by their highest fan speed - chances are, you probably won't be running it that high all the time. It is better to get multiple smaller units that are local to the area you're using versus a single large unit for a big space. These do not move air vigorously (less than your standard fan) - so even if they say they'll do "3000sqft" - they are assuming you're in a single rectangular room with only four walls. If your home is 2000sqft with lots of rooms and hallways, a single unit will not work. However, the number one thing about any air filter is that they are a continuous cost and will only work as long as you are regularly replacing their filter media. At least with air filters you will be able to see exactly what they're doing when you replace them - mine are usually pretty grey-looking by the time I take them out. Oh, I wouldn't bother with all of the fancy filters (like pet, charcoal, or whatever) unless you have a very specific need for them. Those are are mostly gimmicky. Air quality monitors (like the Airthings) are also not needed - and in fact, many of the higher end filters have particulate sensors in them. It's mostly informational for people like me who just really wanted to know if all of these filters actually did anything. Plus, AQ monitors don't tell you *what* the stuff in the air is, they just tell you it's high. I found out that vaporizing humidifiers make PM sensors show deep red spikes because they're literally throwing tiny bits of water into the air (but it's not specifically a negative thing - especially when you're trying to raise humidity). For the "do they work?" question, my answer is "Eh... sorta." They definitely help with things like odors (such as from cooking or pets). I have not noticed a huge decrease in dust build up (but my house is not sealed in any shape). I definitely notice that my allergies get worse when I go outside versus hiding in my house, but it's not like they're completely eliminated when I'm home. So for me at least, they help, but they're not some sort of miracle cure that'll magically fix everything.

I own a Levoit 300 and it's actually quite nice for small rooms and you can find aftermarket filters that are reasonably priced. At times I wish I'd sprung for the Coway Airmega due to the higher CFM.

I like the levoit 300s because you can customise the PM2.5 level that triggers it to turn on and off. Others with auto mode I’ve tried are set far too high to keep the air clean (as is the 300s by default) . It doesnt clean VOcs at all though even though it claims to . i havent found a purifier that does tbf

I brought a bigger room sized Levoit 300 into my fam members hospital room and put a piece of tape on it with their last name and no one stopped us and they moved it each time with their room changes ( acuity was back and forth) and usually it got turned back on after a move but a couple times I did need to reset. I also made a cute sign requesting masks be worn. Some hospitals are very aggressive about plugging things in but never had a problem at this one, I think the Levoit being white and clean looking helped and we told people it w as air purifier when asked.

I mean.... I mentioned the part about them having no reviews and being at a sketchily low price point of 1/2 to 2/3 the cost of everyone else. There are really only a handful of air purifier brands that have demonstrated reliability, affordability, and effectiveness over several years, and don't dabble in post-apocalyptic/steampunk decor -- coway, levoit, blue air, winix. If you want to pay more, there's iq air, alen air, and a few others. For $110, you could have bought a blue air 511 and almost a 411, a levoit 300, almost a Levoit Vital 100s, or a Winix a231. The winix 5500, the coway 1512, levoit vital 200, and the blueair 311 are all at this CADR, but for closer to $200.

Levoit 300 just came today and it seems lovely. And pretty quiet too.

The displayed PM2.5 value on our 3 Core 600S is completely off by around +20ųg/m3 so need to ignore that and use a third party air quality meter. We have a Core 300s as well for the office which displays correct values, not sure what that's about. Other than that, they are fantastic at cleaning the air! We went for the bigger 600S for our 35m2 bedroom because it allows to have it on lower fan speeds at night for similar CADR as the smaller models at max speed which is too loud for sleeping. We live in a dusty climate and keep the device at speed 1-2 at night and the rooms PM2.5 and PM1.0 are consistently at 2-3ųg/m3 now. Best bang for your buck for sure. Coway Airmega 400 has the same CADR and costs 2x as much for example.

Why don't you want it cleaning the air 24 hours a day though? I have a DIY corsi box and a levoit 300 in the bedroom running all the time. Bonus is it provides white noise at night. I leave all of the air purifiers on in the house because air is always circulating between rooms and I count the cadr as overall house cadr

Yes, I love the levoit brand and I have several of the 300's. That's also the one I take to the dentist appts with my own battery.

It probably won’t damage the purifier, but it can cause issues with the filter growing mold or developing a smell if you use it in very humid spaces like a bathroom longterm. For a few days, it’s not going to affect it that much. I would however set up a fan in the window to suck air out of the bathroom and then run it while he’s in there and after he’s done. That’s gonna be honestly more effective than a small air purifier and help with the air changes. If your home has an HVAC system though (meaning air is recycled throughout the house), you need an air purifier in your bedroom just to be safe. The Levoit 300 is probably fine for a bathroom type space, but it is generally undersized for most rooms. Better options would be something like the Levoit vital 200, Levoit core 400/600, Coway Airmega, or AirFanta 3.

I have: 1x IqAir with all the add ins and pre filter 1x Austin it 1x Levoit 600S 2x Levoit 300 1x 24x12x2 MERV 12 Filter (corsi style) but with an HVAC box and INLINE fan. All my HVAC return filters use MPR300 filters. I vacuum all the time, and run a robot vacuum multiple times a day. The goal is keeping the dust on the floor from floating UP and ON to elevated surfaces. In return the air filters last longer.

I have levoit 300's. I didn't realise before I got them how much they would help with hayfever. Its worth buying bigger units than you think you need. If I buy another, i will use this company 10% off today https://smartairfilters.com/uk/en/product/sa600-air-purifier-5-speed-version/

Find a levoit 300 cheap on fb marketplace. Very good purifier and you can prob find one for $30-$40 ($100 new)

Same they worked well for me during wildfires for at least pm2.5

I have two levoit air purifiers and I swear by them!! I strongly suggest buying at the 300 purifier, I got a mini and didn’t like it so I got the 300. When it came to buy new filters, regardless of size they’re the same price, so while it’s a bigger investment to get the 300 ($100 vs $50 mini), it’s the only time there’s a difference in price. The mini stays right by the litter box for that but if the litter is reaching the end of its freshness, the mini doesn’t keep up but the 300 will. 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. Another thing I like about them is that sucks up hair. I take the filters out and shake them off outside to wack off the hair but they really suck in the hair that’s just floating around the room.

Hey! I have 5 Levoit smart purifiers around my home on Google Home ecosystem, and it works flawlessly.

We have several LeVoit smart purifiers and they’re outstanding. Our old home is super dusty and these units have made a huge impact on how we feel and no longer see tons of random dust particles in the air.

I have had one Levoit Smart Air Purifier in every room of the house for several years now. I initially bought a few and but was uneasy about the expensive investment I was getting myself into. But I ended up liking them so much I kept getting more and more. I have no regrets even though I’ve spent over $1500 total on them. They make a huge difference (home for a small family + several pets). Actually only regret is I didn’t do this sooner. I’ve suffered from allergies most of my life, to the point that I always walk around 24/7/365 with giant wads of tissues in my pockets. These things make it much more bearable. Pro-tip, you can prolong the filter life by vacuuming the gunk off them. Probably should do it outside as the vacuum tends to agitate some smaller particles in the air.
