Storm II AP-1523D

I noticed the same recently. Each model's price is up by 6,000 when compared to my last purchase a few years ago. But having said that, I only trust Coway. All these models offer excellent performance and reliability - AirMega 250, AirMega Storm and AirMega 150.

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..

The Dyson air purifiers actually work the worst alongside its competition ...look at some smaller studies on YouTube, they did a horrible job not to mention the price difference. Theyre crazy expensive for an inferior product. I use blueair and it does a great job , rates pretty good amongst the others , I think the only other better one was winix or Conway.

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.

I know you asked for cleaning help, but what has helped me wake up without a stuffy nose, and my chest pain (I have athsma) exacerbated by the carpet and dust in my house, was getting a window fan, where it exchanges the air inside your house without outside air. It’s amazing!! Plus I always have a levoit air purifier going. I bought a Conway, and it didn’t help my allergies, and the cheaper levoit helped so much more!
