Cancels high pollen counts.It does a great job on the lowest setting, which is so quiet, that when I walk by it I pass my hand over the top to feel the air blowing out.My sinuses are thanking me for getting this.

I've been using these for over a year now. They work great. Have one in each bedroom. They collect a lot of dust and are usually very quiet unless they get dirty. They have different light modes and fan speeds. Also has a timer for auto shut off.

I’m pretty happy with it.I bought one and tested it just to see. I’ve always rented apartments, as an adult. Normally started out as 1/2bdrm and as I grew a little older I downsized into decent sized studios. I stand by the statement if you’re a renter you for sure need to have an air purifier. I’m sure we can all connect the dots on the reason why. However -Despite my vaulted ceilings and ect, I did see a significant decrease in dust. I currently live with my s/o and my small/medium sized dog. He doesn’t shed much and ect. So I switched from my old purifier that was a bit old and outdated because with smaller space - although this studio is sizable I’d say it’s equivalent in size to some of the smaller 1 beds in my area.. more bodies - especially a dog, I’d say the same for even a 2bdrm apartment, you need to cycle that air. Not to mention the inevitable mold from past tenants, used carpets and ect - just a better idea all in.It has helped my wife’s sinus issues as she’s always a bit stuffy at times, this does also improve her sleep quality.The noise level is QUIET even on full. I do sleep with a larger fan though. - it does in fact help with kitchen smells, and the smell of my dog - perfumes - soaps in the shower - and his occasional accidents (poo - although quickly picked up).I’d say it works well, and I appreciate the LOW energy use. 12W is basically a car outlet. I do run them at full with the occasional 20-30min venting of my unit through obviously an open window when they are shut off and also off while we are at work.So to sum it up, I bought another - and placed it in the opposing corner of my apartment. I’m sure I will now see double the benefit.I do recommend if your situation is similar to mine. - cannot speak on a house.Update - Months in, haven’t needed to change a filter. I do occasionally take the filter out and vacuum off the prefilter. - I’m not sure if this will make a significant difference in lifespan but my logic tells me it’s more optimal for air flow. When I do that I also wipe down the outside air holes and top with a Clorox wipe as it does collect some dog hair that gets sucked on and but not through the holes. I’ve been running them dual. Really helps with making everything feel cleaner. I’m also sick with a bit of a cold right now and I can say it certainly is helping me not sneeze as much. Visible dust levels are down as well. I don’t have to wipe things down nearly as often. I’d say it’s working great! Would recommend. Filters aren’t very pricey either, since I have two, the two packs are perfect for swapping both of them out. But if you’re only running one, guess you get a filter and a back up for $11 a pop. Not terrible.

Why did you pick this product vs others?:So far so good, has not broken down on me and it does clean my air. I can see it in the filters.

I stuck the AC400 on the corner of my desk, and half the time I forget it’s even running. It’s whisper‑quiet—around the 20 dB they claim—so it never competes with calls or music. The rotating LED ring is a nice touch; I leave it on a soft teal at night and it doubles as a mellow night‑light.Performance‑wise, it’s pulled the weird paint smell out of my home office in a couple of hours, and the prefilter grabs pet hair before it floats onto my keyboard. Filter swaps are tool‑free and take maybe a minute. No ozone gimmicks, just a solid H13 HEPA that does what it says. For the size and price, it’s hard to beat.

Es muy buena compra, funciona muy bien y el modo silencioso realmente funciona bien, casi no se siente sólido en la noche

Shipped and rec’d on time. Good value for the listed features ($26), but does it work? No noticeable difference in air quality when using, regardless of room size. Can be a bit noisy when set at higher levels.

Just just got this and I used it overnight. Usually when I walk in my room to go to bed, the room has a musty smell. Well, I went to bed last night. The room smelled nice and clean and I just noticed a huge difference.
