Airmega 50 goes for around 10k around Diwali.
I have 3 philips 4000i 1 philips 4200 and a coway airmega 50.
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?
If you cook a lot, you're generating a ton of stuff that is likely better vented outside—doubly so if you have a gas stove. No air purifier is going to be better than a box fan in the window of your kitchen blowing out. We've used a variety of fans in our kitchen window for the past decade, and an air purifier we have just outside the kitchen(a Coway Airmega fan that has a smart feature) doesn't have to ramp up much anymore thanks to the volatiles never actually making it out of the kitchen.
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..
