Levoit - Core 600

I have a Levoit Core 600 and Core 400. I think they work pretty well, but my air quality is pretty good already. Both purifiers turn the fan to a higher setting when I'm cooking, or if I have scented candles burning for a while. If I leave my front or back door open, it indicates lower quality air, and adjusts the fan speed if necessary. My furnace/AC filter was unusually clean after 3 months of use, and I attribute that to these purifiers. I like having them.

I’d go with two Levoit Vital 200s.  One for your living room and one for your bedroom.  Fantastic performance for the price.  That’s the minimum I’d want for my parents although I got them a core 600s for the living room and 200s for their bedroom.  But if you’re rich rich and want to go high end you can find a good purifier at basically any price point.  

Levoits are still good at virus clearing even though they are not technically HEPA.

Please see the stickied thread in this sub about dust. Purifiers are not designed to get rid of dust. Shark sucks. Don’t under any circumstances buy one. BlueAir is fine, but overpriced and the filters are expensive. Levoit is a good, cost effective brand. It is on par with Coway and Winix. You cannot go wrong with a unit from any of those manufacturers.

Levoit Core 600. It’s not the most sophisticated air purifier in the world, but it fits you budget and will definitely help mitigate many of the pollutants

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.

Have a core 600 and it’s fantastic!

IqAir, Austin, Levoit They are all running right now at home. Visitors often tell me the house smells very clean and pure. I have a Levoit 300 by the front door. Levoit 600 in the living room. Austin on the kitchen counter in the corner by the stove. An IqAir in my master. A Levoit 300 in another bedroom. MPR 300 filters for my HVAC.

IqAir It’s not “smart”. But I don’t need it to have WiFi or smart features. I need it to cleanse the air. I have a Levoit in my living room and the only thing that is neat is telling Siri to turn it to 100% or back down to 50%. The IqAir sits in my master bedroom. It smells clean and crisp in the bedroom!

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.

I have a levoit and it significantly helped my asthma. I went from going to the hospital 2x a month for asthma attacks to I actually haven't been since before I got my levoit 600s

I went with levoit because of the ozone. I live with someone with asthma. Also the levoit 600’s covers a bit more space than Winix. Winix does have cheaper filters though. Starting to doubt my pick but the ozone is a deal breaker for me.

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 will also say that I have a Levoit 600 S and I’m very disappointed in it. And I also have a mod plus which I love so much but it just does not move air like the MA125 I use a sensor hooked up to Home Assistant and just watch these different ones work and I kind of wish I hadn’t bought the levoit

I have 2 Levoit brand purifiers. A smaller one in my bedroom and and a bigger one for living room area. They are quiet, dependable, and have been working well.
