WINIX A231 Air Purifier for Bedroom Up to 1110 Ft² in 1 Hr With Air Quality Monitor, True HEPA, Carbon Filter and Auto Mode, Captures Pet Allergies, Smoke, Dust

I don't usually write reviews, but please, if you are buying this, it is LOUD. We wanted this in our room, but it is too load, even in sleep mode. There is basically no difference between sleep mode and low mode - they make the same amount of noise! However, it does clean the air quite well.

I bought a Winix 5500-2 about a year ago and was/still am very impressed with it. I decided to stay with Winix and get this smaller version for a medium sized bedroom. The functions are simple like the bigger brother 5500 and it's almost silent on the lower settings. It also has plasmavave. Where it does differ from bigger brother is on the filtration system. Technically it has a carbon "coated" pre filter and the air finally passes through the hepa filter before exiting the purifier tower from the top. On the 5500 the carbon filter is on a totally separate layer or filter medium so there are 3 distinct filter stages that are physically separated from one another. On this smaller version, there is only one filter or in other words it's an all-in-one filter that does 3 jobs. Is it as efficient ? I doubt it but it's probably close. It is of course substantially less expensive and the replacement filters are probably less expensive as well (I haven't checked). I believe it's an excellent choice for a smaller room but if I had money to burn (and I don't), I'd take the 5500-2 over this one even for a smaller room. One more thing of note for some: The A231 looks very nice and modern and will fit in any decor. It looks much nicer than the 5500 which could easily be mistaken for a big heater.

Very good quality, especially for the sale price. It's just the right size for my bathroom and definitely removes dust and odors efficiently making it extremely functional for my application. I bought this to be my second WInix Air Purifier because the first one resides in my bedroom, has been excellent, was a great price and has been super reliable. It's also almost silent and works GREAT! Get this brand with confidence fme.

Primer día que uso, lo puse a prueba con resina para impresión y no percibí su olor, el filtro reconoció el olor antes de que yo lo hiciera

Es super silencioso, fácil de usar y. Asi no ocupa espacio. El precio es muy bueno.

We’ve had this on a dresser in our room for about 3 or 4 years now, running continuously. For most of the time, I’ve had it on the “automatic” setting, which means it generally runs at medium speed, turning up to faster when it senses particulates in the air, then returning to medium. It works VERY well, and has reduced my allergies a great deal. The noise level is quite comfortable for us, but we don’t mind a soft fan sound. There are three manually set regular speeds, low, medium and high. The low speed is quite quiet but still a little louder than the night mode speed. If I switch it to night mode, it falls to whisper quiet, hardly noticeable. We use a genuine Winix filter in it, and replace it about every 9 months or so. Replacement is super easy. It has no weird sounds like another reviewer has mentioned, but runs smoothly and efficiently. We’re completely satisfied and would buy this same one again for certain.
