Coway - Storm II AP-1523D

I love my coway

Filter going from 2019. Machine menu says no need to replace yet .

Cowin . Used only in Delhi winter pollution

Have the IQ air does not catch dust or similar. I ended up buying a.Blue air that does and running both. The air quality that comes out of the IQ air is excellent, but if dust is your issue, is not gonna help. Blue air smells like plastic in comparison.. tried the Conway and there was so much plastic offgassing. I returned it..

I got some Conway ones on sale for a main level and bedroom in my house a while back. My plan was to help alleviate dander, allergens, and fire smoke. I can't say I have any empirical evidence of their efficacy, but I'm glad I have them. If you have a couple hundred bucks and no central air, I think it's worth it.

We have two, a Conway and a Fellowes AeraMax 300. Both are excellent. #

2 Conway and 1 Winix currently. Had 3 Levoit’s but they all died between 12-24 months. Junk

I love that it's super quiet, I just leave it running all night and forget it's even on.

I’ve got a Conway that’s been going strong for 10 years.

The Winix (Costco version, I believe 545) does well in our LR but it definitely doesn’t do anything for food odors. It’s also a bit industrial looking if that matters. If it was on sale at Costco I probably wouldn’t hesitate to pick another one up. Since this Conway gets so many great reviews, thought we might try it. Still on the fence though

I feel for you, OP. I am an allergic-to-everything person to the point that I've needed to move homes to get away from paint, varnished wood, carpet, etc. The biggest trigger for me, though, and maybe for you is any centralized heating and cooling system. The systems' filters don't matter - the room's unfiltered air is also being blown in your face. I haven't found a purifier that can offset this problem. I don't use ACs and all my heat is water-based or electric. I experimented with Dyson - if it's the model that provides heating or cooling, there is a chemical in the device that can cause reactions. You can also be sensitive to the material in any carbon filter, like coal. The imperfect journey continues, but I ended up getting a custom purifer from Aller Air and I use it in the same room as a Coway HEPA. One for gas and chemicals, one for particulates. It still doesn't save me completely from my dusty old building, but I can now be confident that it's the only issue. Good luck!
