"If you want more controls, the Xiaomi app is pretty good. I've set automations for when I want it to turn on and off based on air quality and time of the day so I don't have to worry about turning it on or off. I can just leave to office knowing it'll manage itself."

"The Xiaomi will clean air very well, but filters clog up quickly."
"That factory pre filter is a thin mesh attached to the HEPA filter. It is not washable or removable therefore it does not prolong filter life."

"Regarding the cheap plastic smell from Coway, I experienced something similar with the Xiaomi 4 Lite, which was quite unpleasant."

"I have a Xiomi CN-4 Lite in a small bedroom and it helps a little, but could definitely be better."
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

r/delhi • Real-Life Comparison: Xiaomi Air Purifier 4 vs. 4 Lite ->Great. No nuisance
r/delhi • Real-Life Comparison: Xiaomi Air Purifier 4 vs. 4 Lite ->Hi there. I bought Mi 4 Lite yesterday.
r/delhi • Real-Life Comparison: Xiaomi Air Purifier 4 vs. 4 Lite ->Seeing similar post thought of posting my birthday gift. Saw Bryan Johnson walkout and realised how we are ignoring air pollution. Pune's aqi is always around 120, it is not healthy. And God save you if you are traveling on 2 wheeler in pune's traffic. EDIT- review- Pm 2.5 is around 40. After 10 min on full power with windows 2 Inch open pm 2.5 gets down to below 8. room size 110 sq ft. Noise - not audible if fan is on 4-5. Otherwise noise is there..
r/pune • Bought Air Purifier as Birthday gift for myself ->Mi 4 lite, seems to be the best in range
r/pune • Bought Air Purifier as Birthday gift for myself ->Mi is best value for money
r/pune • Bought Air Purifier as Birthday gift for myself ->Na bhai, mi 4 lite-10k ka..
r/pune • Bought Air Purifier as Birthday gift for myself ->It's good unit, quality filter, okay cadr for size. Xiaomi should have factory pre filter installed. https://youtu.be/Loq0OlYW-Zg
r/AirPurifiers • Xiaomi Air Purifier 4 Lite ->Xiaomi is good. Have been using it for a while. Whatever you buy - ensure it has a AQI/PM2.5 monitor. One reason for using air purifier is mental satisfaction. So the purifier should tell you how it is performing & reducing the AQI (in numbers - not colors)
r/gurgaon • Suggest a good Air Purifier ->I bought the [Xiaomi Smart Air Purifier 4 Lite ](https://www.mi.com/global/product/xiaomi-smart-air-purifier-4-lite/)a while ago for the 100,000 krw. Does the job at a fraction of price compared to similar models. Runs very quiet at low speed.
r/Living_in_Korea • Air purifier recommendation ->[샤오미 미에어 4 라이트 AC-M17-SC (해외구매)](https://prod.danawa.com/info/?pcode=16219547)
r/Living_in_Korea • Air purifier recommendation ->I'm using the [Xiaomi Smart Air Purifier 4 Lite](https://s.lazada.com.my/s.ojMYP) and the [Xiaomi Smart Air Purifier 4](https://s.lazada.com.my/s.ojMbw) at home. My mom started having runny nose every single day mid last year and so we decided to get these 2. It actually helped her significantly. Both of them offers more of less the similar features so you can see which one you want to go for Plus points in my opinion is the ease of use. Simple control on device and shows you the filter health and can choose different modes. If you want more controls, the Xiaomi app is pretty good. I've set automations for when I want it to turn on and off based on air quality and time of the day so I don't have to worry about turning it on or off. I can just leave to office knowing it'll manage itself. You can see the filter health on the app too. Replacement seems to be simple, I managed to remove it to take a look but haven't replaced since health is still at 79% I've tried Coway Air Purifier before, took it for a week from my sister before getting these Xiaomi ones. It's way too big, kinda loud and it's a subscription based so you gotta pay monthly which I feel isn't worth it at all Edit: The Xiaomi Air Purifiers can also get loud but only when the air quality is bad and over 100 reading. I've only experienced this when mom is cooking or had contractor do some fixing at home
