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’ve only been using this WINIX air purifier for a few days, but I’m already impressed. I noticed the air felt fresher within the first day. If you’re someone who suffers from allergies, is congested from A/C, dust, pollen, smoke, this is honestly a game changer.It was super easy to set up, runs quietly, and just makes the room feel cleaner. If you’ve been on the fence about getting one, this is your sign you won’t regret it!

This compact Winix air purifier works really well and makes a noticeable difference in air quality. It’s small but powerful, and it runs quietly even on higher settings. I like how quickly it helps reduce dust and odors in the room. It’s also easy to use and maintain. Overall, a great choice for keeping the air clean in smaller spaces.

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.

I like that this has a sleep mode, whereas it is extremely quiet (my fish tank motor is louder) and only the light from the power button is present, which doesn't seem to light up the room but may bother someone who prefers pitch black to sleep. Also, the air smells more crisp and my daughter, who has allergies, has been having far less attacks. It is also light weigh, the filters last forever, it's easy to clean, and you can turn off plasma wave (which I never use because it can be problematic for asthmatics). My only complaint is that I'm not sure how well the air quality sensor works. I've set my son's poopy diaper right next to it and it still said the air quality was good. It also said the air quality was good when I could smell a strong smoke smell from my neighbors burning. However, any time someone is cutting onions in the kitchen, a room away from where the purifier is, it says the air quality is poor to very bad. Other times it randomly says the air quality is poor/bad for no reason discernible to me, and without there being any activities that may have effected the air quality. All in all it does its job and does so very quietly, which is what was most important to me due to having sensory processing issues, especially related to sound.Edit: air quality sensor seems to be working. It's picking up b/o and flatulence.Also, my son has knocked it off the shelf several times and it seems pretty sturdy.The coating on the wire is coming off near the machine.Also, I kept noticing a faint helicopter noise coming from the machine where it does atop a book shelf (not recommended distance from the wall). I was worried it was the fan and quite irritated by the sound. I realized that what was causing it was the slight movement from the fan leading to the wire moving back and forth against the wall where it was pushed between the wall and the shelf. I pulled up more slack and moved the unit out from the wall as much as I could and the sound stopped.Only real complaint : I wish that plasma mode had a lock on it. My kids keep turning it on, which is an issue for the asthma and allergy havers in this house.

I bought this one and another brand at the same time, the coway airmega, and this one performs just as well in my opinion. It exchanges air very quickly, which I can tell due to using it while I cook etc. It helps well with smells and it’s pretty quiet. The plasma setting is a little noisy, but I only run that during the day. Overall a good purchase

The air purifier WINIX A230 Air Purifier for Bedroom Up... came last June .. 2025.It met my needs. Cleaned air nicely.. was a great unit for my needs. I have seasonal allergies.⚠️ however it has quite.. fan made a loud noise and motor quit.I M presently in contact with company.🥺The company is replacing this air purifier.Overall customer service and unit are worthy of 5 stars⭐️

Amazing a cleaning up the air and providing clean air for everyone. It also has automatic mode which is a nice touch.

I bought this to have in my bedroom to supplement my other air purifier in my living room which is the Winix C545. That one has been great for 3 years of constant use now with zero problems so I thought I’d stick with Winix for my second purifier. I like the look and size of this new one, perfect for a bedroom. Others weren’t lying about how loud it can be (when compared to the C545, it is quite a bit louder, but think about it- it’s a smaller purifier doing the work of a larger purifier). I keep it on low and it’s fine. High setting is definitely loud, but would be great for people who like to sleep with white noise. It’s not loud enough for me to deduct stars from my review. The air indicator ring light is really nice looking and it does change colors based on air quality quickly (candle smoke, fragrance spray, etc, will all make the air quality light change colors and prompt the fan speed to increase if on auto. It works!) I mostly got this one to help with dog smell and so far I can tell a difference with noticeably fresher smelling air when I come home.

This air purifier has made a massive difference to my sinuses and allergies. Keen to get a second one for my home office. This one I have been using in my bedroom.

A friend has the larger Winix model and recommended the brand. I have been using it for almost 2 month and it runs quietly and rotates through the cycles automatically. I moved to a busy road and could feel the dust and diesel fumes, and this purifier certainly refines the air quality. Very pleased with its performance and how it fits into my bedroom. Cute and contained. Plus the seller is absolutely on top of sending you information on extra filters or anything to do with the product.

I’ve been using the WINIX A230 for a bit now, and it’s been a fantastic addition to the house. It's incredibly quiet, especially on the lower settings, making it perfect for a bedroom.​What I like:​Auto Mode & Monitor: The built-in air quality monitor is great. You can see it change color when it detects dust or cooking smells, and Auto Mode instantly kicks up the fan speed to clear the air, then drops back down to a whisper when it's clean.​True HEPA Filtration: It does a great job capturing dust and seasonal allergens. The air just feels crisper and cleaner.​Sleek Design: Unlike some bulky box purifiers, this one has a modern, cylindrical look that blends right into the room without being an eyesore.​Overall, it covers a ton of square footage for its size and works exactly as advertised. Highly recommend it if you want something set-and-forget!

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.

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
