WinixA231 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

After trying several different brands, this purifier has become my personal favorite. I’ve actually purchased two for my home because my roommate has severe asthma, and this has truly been a game changer—especially since our apartment is fully carpeted.It’s definitely worth the money. The air flow is great, and you can really feel the difference in air quality. It works quietly and efficiently, making it perfect for people with allergies or respiratory issues. If you’re looking for something that actually makes a noticeable difference, I highly recommend this purifier!

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.

I've been using this for 2 months now and it's a very nice air purifier. It's in a bedroom and is very quiet at night using the night feature. In normal mode it's not loud per se, but it is something that would distract me trying to get to sleep. Also, the night setting turns the ring of light off, I get distracted by the light a little bit since it's very noticeable in a dark room. Cleaning the filter is very easy, as is disassembly and reassembly. It's definitely something I would get for other bedrooms in the house.

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.

Works well for its size but the 5520 is the best for your money. Slightly bigger but this is nice if you have a room with less traffic and you need something smaller. Still works well, get the room clean smelling and micro plastic free. Just slower not nearly as good as the other bigger one. The bigger one has the room clean very quick.

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.

College life!!! Looked for an air purifier for my new college student and we came across this one! So happy with it! The power is great and love that it has self adjusting fan speed based on real-time air quality., yet it’s super quiet. We set it up the day we moved him into his dorm room and already the next day or two he could already feel the difference in the air quality in his room…. He suffers from allergies so he appreciates good quality air! Overall I’m impressed and completely satisfied! Would recommend this 100%! It’s a great buy for the price!
