Coway 150 wont be able to match up with the units you mentioned I agree On Coway UK website, airmega 150 is listed as an item under "small spaces" category. Also in UK they are giving Activated Carbon filter instead of the urethane carbon sheet being given in airmega 150 sold in India. I think its not good that coway india is charging higher for their models in this November 2025 month because of pollution and protests . there is huge demand of purifiers for sure but they should adjust their rates. Coway products are more expensive than other brands I think. And need to compare the above winix, xiaomi products with their "medium space" purifiers I believe. Also want to say that I just love my coway airmega strom AP-1220B machine. Its a beautiful and well designed effective air cleaner.
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.
Coway AP storm. Great device. Switchbot on top?
Coway airmega (non-smart) has been a game changer. Been using it since 2020 with 3 cats and multiple seasons of prolonged smoke from wildfires.
I love my winix plasma wave. I also have a Conway air mega that’s sized for my bedroom that’s been going strong
I have two Conway airmegas (and two blueair and two winx… small house but multiple levels). LOVE the Conway airmegas. Two cats, one dog and two people. I have them mostly at room transitions (near doorways and stairs). The amount of dust and pet hair they pull in is amazing.
I have a big Conway airmega I got when living in Los Angeles for the bad air quality. Then we have a few very small ones right next to the cat litter boxes. I bought winix ones that have good air turnover but are noisy for the bedrooms when we moved bc this house had some smell and possible mold issues. The winix are nice but I got refurbished and two of the three are noisy.
I do, helps with seasonal allergies and generally reducing dust in the house. We have a Conway airmega on each floor and I built a diy air filter (CRBox) with pc fans and furnace filters for my basement office.
