A very good air purifier with a washable pre filter and carbon filter.Design is okay. Easy to install .Noise level is surprisingly low and in night it automatically reduces fan speed if auto mode is selected. As for allergens I think it’s doing a decent job.Its a good value product overall. Plasmawave feature actually works and odour is drastically reduced.

Air quality is great. Noise level nothing. Value for money. Works amazing because new construction going lots of dust is coming. It’s very easy to handle. Its portable not heavy to move in house

This device definitely helped improve the air quality. I wish they had given the washable AOC carbon filter with this device since the next model has it. The device is silent at fan speeds up to 3 and audible beyond that. Some might think the sound is too high in fastest mode, but if you usually keep the device away from you, you will not hear it. The device has auto function which senses air quality and adjust the air flow. It also has a time that you can use to turn it off automatically at a set number of hours. The night mode turns off all the lights, so its useful when you are using this device while sleeping. The build quality of the device is pretty good. Overall, I am happy with this purchase.

Good air purifier with all the required features. It turns red if the AQI in the room is high, and orange if it is moderate. Blue means the air quality in the room is good. It has an auto night mode, which switches it to silent operation when the room lights are turned off at night.

The packaging that this air purifier arrived in raised serious concerns (see the image attached). The air quality indicator is a gimmick, at least on my unit i could say that it was acting crazy, on auto mode, it would just turn red/amber on it's own even in a empty-closed room of 130sqft and the surrounding AQI is 130-140. Given not so harsh pollution and this air purifier (based on specs mentioned) being more than enough for the room size, this thing should've just stabilized after a while but it didn't. On top of this, it is a bit noisy, it almost sounds like a cheap exhaust fan on top speed. Lastly, I'd say don't fall for the plasmawave technology, it generates small amount of ozone which yes is a pollutant, the company might say it's negligible, the tradeoff is nice and works wonders to clean air but for me it's a clear no-no. At the end, I had to return this.

very nice product

Using this air purifier since last week. Airflow is awesome. Working fine and doing its work inside my living room in Noida. Installation is simple as per the user manual which is included in the box. Got the delivery within a day. Thanks amazon !!

I’ve been using the Winix air purifier and I must say it’s one of the best investments I’ve made for clean air. The filtration is powerful—it noticeably reduces dust, allergens, and odors within hours. It runs quietly, even on higher modes, making it perfect for bedrooms and living rooms. The design is sleek, easy to move, and user-friendly. Overall, an excellent choice for anyone serious about improving indoor air quality. Highly recommended!

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.

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.

The seller is lying; this is advertised to come with a remote control, which is why I chose it, and there is no remote control included, and it cannot be connected to an app. BEWARE - Do not recommend buying this if you require remote operation.

Es un muy buen producto, lo compré porque donde vivo hay actividad minera cercana y el polvo es una molestia, además gracias a la última contingencia ambiental no se podía abrir la ventana sin que el olor del humo colmara la habitación por horas. Resolvió ambos problemas sin esfuerzo, solo basta con colocarlo en modo automático y dejarlo trabajar. El ruido en su potencia de ventilador más baja es casi nulo, incluso en un nivel intermedio apenas y podrás percibirlo, la cosa cambia en su nivel máximo de potencia donde el ruido es más que perceptible, pero rara vez lo operarás en dicha potencia. Mantiene el aire limpio y sin olores sin problemas, yo ya estaba a costumbrsdo a dormir con la nariz tapada debido al polvo y tenerlo en el cuarto ha sido un verdadero alivio. Es fácil de limpiar y los filtros son asequibles. Mi cuarto mide 4x 6 metros y lo coloque en una esquina, no tiene problemas para limpiar el aire contenido en tal volumen.
