I just got the Winix A230. Mine is set on auto and has consistently programmed itself at low and I can't hear a thing.

I have a Winix A231 and it seems to do pretty well, I smoke weed in my house/living room regularly and you wouldn’t be able to tell, I leave it running 24/7, 2 years in and still going strong However you’ll want to consider multiple if you’re having constant dust problems, also make sure you regularly change the HVAC filter maybe also up the MERV value. Odor can be controlled mostly by charcoal filters. Make sure to change those regularly as well

The Winix A231 for the main part of the house and a Bionaire Desktop True HEPA Air Purifier for my bedroom. They are cheapest at Walmart. I thought I might need a third one because my house is shaped like a U but the two together work fine. I didn't even have them turned on over the summer but now that the rains will be kicking in and doors closed I have them on again. Both have washable/reuseable filters.

Hello, living in Buffalo, NY, USA and room in question is small, 200 cubic ft. Currently have a Winix 5500-2 and A230 elsewhere in house. Looking for a purifier that meets needs below: 1) HEPA Filter 2) Non ionizing 3) **Has actual carbon pellets** (like the 5500-2) and not just a carbon impregnanted filter (like the A230). Primary concern for this purifier is for odor. 4) As small as possible (A230 size or even smaller, looking for smallest size options possible) 5) Less than $500 Thank you!

I have the Winix A231 and BlueAir 511. I started with the Blue Air 511 which isn't terribly loud when it's on blast. I added the Winix A231 as an extra precaution. This one is the loudest of the two. I mask when my office door is closed and the air purifiers are running. My workplace has an HVAC system and from the looks of some of the vents, I know the filters for individual rooms haven't been replaced. There's clumps of dust visible in one of the air vents in my office. Considering there's a possibility air from another room is being mixed into the air coming into my office, I mask. I've been at my current job for almost 3 years. For the first 2 years I've been fine with the Blue Air 511. I caught strep once because I didn't wait long enough to remove my mask after two coughing kiddos left my office. That incident prompted me to start bringing my 4Lite to work so I could eat or drink soon after someone left my office. I've been around COVID and flu-positive people at work and didn't catch it thanks to my N95 In some cases my air purifier helped too- it just depended on where I interacted with the person. I was recently gifted an elastomeric mask. I doubt I'll wear it to work because I would be too self-conscious. Here's a helpful article on the difference between laminar flow and turbulent flow. [https://smartairfilters.com/en/blog/the-truth-about-laminar-airflow-in-air-purifiers/](https://smartairfilters.com/en/blog/the-truth-about-laminar-airflow-in-air-purifiers/) Unfortunately Smart Air is trying to sell their QT3 as a laminar flow air purifier, and while it may be laminar flow, it has an incredibly small stream of air. I do not recommend it. All their other devices are great.
