“By the way, I don't find Air Purifiers (I have four different ones) helpful in my case, perhaps the dust particles I am experiencing is larger than the units are built for.”

“it pulls some pet allergens out of the air. Works fairly well as long as the filter is alright.”
“its carbon filter has a few times more pellets than filters on these Levoit's, which means it is more effective in neutralizing bad odors and VOCs.”
“Less than two years in, the fan of the air quality sensor on one of our 400s started making a grinding sound and gave off a burning smell. They sent a replacement right away.”
“Levoit came out with a purifier recently (Levoit Core 400S) that allows you to track PM2.5 in an app over time. It's nice to have proof that PM2.5 is at minimal levels, typically 1-2 for me.”
“I’ve now had two different Levoit Core 400s, Levoit support told me to just refund it”
“I can run 2 levoit core 400s purifiers on turbo 24 hours a day/365 days a year and that’s $72 in additional electricity cost.”
“If you want to save money, don't buy the one with the cylindrical air filter. The replacement filter is very expensive (even the non-branded ones).”
“I have a Core 400S, and two Core 300s. They all make the same annoying motor noise.”
“Very happy with this air filter in my place. Change the filter 2 times a year about under normal operation.”
“I've tested the Core 400S CADR using drawdown and it's at least 95% at 0.3 microns, and it matches Intertek's independent test published on Energy Star (which is also about 95% of nominal CADR of 260 CFM). It works”
“They also need calibration to work well, and that's a whole separate area of expertise. As well as engineering to make sure air moves them well, and no light is leaking in. From reading other postings, they didn't do the best job”
“It has made a big difference in my breathing (have allergies and asthma). While how it makes us feel is subjective, it visibly catches plenty of dust which I vacuum off the pre-filter periodically.”
“So I turned it on for 4 hours on high on the first day (22/8). Then I turned it on again on medium for another 4 hours (23/8). Later that night I started to have these symptoms: - Dry coughing - Slightly tight lower end middle chest - Dry mouth and throat even though it was 60-80% humidity.”
“I believe it’s the levoit core 400s. It’s INCREDIBLE right now. Close everything and just let it run. It is a lifesaver right now.”
“I use 3 Levoits, the Core 300, Core 400S, and Core 600S. All 3 are very good”
“I have a Levoit Core 400s and it consumes between 5.8 and 35W, depending on the fan speed. Here at home the air quality is always good, so 99% of the time it uses that 5.8W.”

“I've been running my two Levoit 400S units nearly 24/7 for the past year or so. I've also purchased the Core 400S as gifts for family - three so far.”
“I have a Levoit (core 400s) air purifier and really like it, clears a large room of any smells etc pretty fast.”
“my allergies have been so much more bearable with a Levoit Core400S.”
“my air purifier is a Levoit Core 400S. I honestly love it. There are smaller models too, but I really like this one. It turned out to be extremely useful in wildfire season, too”
“I have a Levoit Core 300 for my living room, and a larger Levoit Core 400S for my bedroom, and have been very happy with them. The 400S comes with a built-in air quality sensor”
“The Core 400s and Vital 200s are slightly quieter and have 4 fan speeds. The Airmega 200M has 3 fan speeds, and the highest speed is noticeably louder than the Levoit models.”
“I also recently bought a larger Core 400S-P for my bedroom. I really like it as well, plus it has a few more bells and whistles like WiFi, Google Home integration, and air quality monitoring.”
