Depends how big your room is , I have Mi 4 Lite and works perfectly for my small room , It costs like 12-13k , But is available for 9k-10k in sales , If you dont want a smart one go with coway air prufiier , I dont remember the exact model name but thats good too in similar price range

Yeah CO2 is almost certainly what you're feeling. That 'thick' sensation after a few hours at the computer in a small unventilated room is textbook CO2 buildup, your body is literally consuming the oxygen in there faster than it's being replaced. An air purifier won't touch this, it only filters particles. The extraction fan suggestion above is the a good suggestion. A small window fan set to exhaust pulls stale air out and forces fresh air in through the gaps and makes a massive difference. Open the door slightly too if you can, even a crack, to give it an inlet to draw from. The dust issue is separate. Once you get proper ventilation sorted, if dust is still bothering you, the [Xiaomi Smart Air Purifier 4 Lite](https://redango-delta.vercel.app/g/Q2A7X8FM) is a solid pick for a room your size, True HEPA, quiet, and has an app so you can flip it on before you even walk in. The [Honeywell HPA060](https://redango-delta.vercel.app/g/P4Z1N9KD) is a slightly cheaper alternative if you don't care about smart features, equally reliable. But fix the ventilation first. The purifier is the finishing touch, not the solution.

Have been searching for a while. Narrowed my list to three options (Have not kept coway Airmega aim as it's cadr is low) 1. Honeywell Air touch v5 ( cadr 380) . Con. Size is small hence filter size would also be small 2. Xiaomi Mi 4 Lite (cadr 380)- saw reviews that aqi meter is not accurate and hence auto mode is not very reliable. Does clean the air though. It also doesn't have Hepa 13 but has true hepa filter 3. Cuckoo respure - High cadr 407 and the biggest filter. Further has 8 year warranty on motor and looks like a no nonsense purchase. Gives a free filter as qell. Have not seen much recommendations on YouTube for this though 4. Qubo 600 - Seems like a decent buy but have read sensor reliability issues and also it's a new brand so no idea of long term ownership. Still confused as to which one to buy

Hey, I ordered Cuckoo Respure yesterday. Most did show out of stock. I just preferred that it comes with a larger filter size, accurate aqui display (color based) , and high warranty. If not this , I would have ordered Xiaomi, since it has a lot of positive reviews on YouTube and Reddit. (Available on flipkart, blinkit and Mi app)

I really like the Xiaomi Purifier 4 Lite Super nice to integrate into HA and set it up according to air quality. I live in a country where we have bad air 3/12 months a year so I have extra air quality sensors as well to measure and adjust the air purifier over the day.

Qubo q400, Honeywell airtouch (V2 or above), Philips ac 960 or 920, agaro royal. If budget is not a constraint then go for Mi Ap4 lite or Coway airmega 150 You can't go wrong with any, just choose accordingly
