"my pad is much more muffled than most others with that layer. ... The noise alone is a winner for me since I tend to move a lot while sleeping."
"Because of this I bought the Nemo Tensor which is much quieter than the Sea to Summit."

"Last year there were wildfires nearby and the airmega kicked itself into high gear (I keep it on auto), so I do really trust that it’s actually doing something."
"We’ve also had terrible Smokey days from the Canadian wildfires in my area and when I last replaced my filter, it was almost black so it was working hard!"

"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."
"May Google/Alexa Support na rin."
"which you can control via an app if you want."

"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."

"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 • AIR PURIFIERS (BUDGET FRIENDLY:(SUGGESTIONS REQUIRED) ->I have a Xiomi CN-4 Lite in a small bedroom and it helps a little, but could definitely be better.
r/Bangkok • What Air Purifier do you use? ->Been using the [Xiaomi Air Purifier Lite 4](https://c.lazada.com.ph/t/c.1r6snt) and it does the job as someone na may rhinitis. Its good OP.
r/ShopeePH • Xiaomi air purifier opinion or other reco? ->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
r/gurgaon • Air purifiers are a highly worthy purchase. The burning question is.. ->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)
r/gurgaon • Air purifiers are a highly worthy purchase. The burning question is.. ->I just got the MI Air Purifier 4, which initially showed a PM 2.5 level of 22 and reduced it to 6. Now I’m regretting it because it looks like my indoor air quality was already good.
r/pune • Bought Air Purifier as Birthday gift for myself ->My room size is approx 260, so ordered the mi 4 lite
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 ->I'm have the following purifiers for my family of 5. Phillips 2887 and 1215. Mi Purifiers 2, 3 and 4. Coway Airmega 150 and Qubo 1000C. Not sure about replacing filters every 3 months. We clean it once a fortnight or month depending on the pollution. Mi and Qubo give filter replacement alarms. They say 9000 hours to 15000 hours. So not sure how you came up with 3 months. 90 days x 24 hours is about 2k hours of filter use only. I've placed the Phillips 1215 in the kitchen to reduce pollution in the rest of the house. I didn't think much about Co2 but will see if I can monitor. I counter room cooling with a oil based heater since it doesn't alter the room humidity unlike convection based heaters.
r/noida • Before buying a Air Purifier, understand this. ->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
r/delhi • Honeywell air purifier v1 vs v5 ->I’ve had a Xiaomi Smart Air Purifier 4 for about a year now, and it’s been great.
r/BuyItForLife • The Best Air Purifier for Home now? Have you noticed a huge difference since you started using them? ->Yes, i have the Xiaomi 4 lite since 2023. You will face issues when you have to replace the filter. Even after replacing the filter it shows as if its 100% used up. I am sure there are ways to fix that, but i havent figured it out yet. Other than that, it is pretty decent. The plus point is the aqi meter, wifi connectivity for the price. However, the filter cleaning bit is not a necessity in xiaomi, but it is good if you can clean it once in a while (needs vacuum cleaner).
r/Frugal_Ind • Got an air purifier for my mom (64), told her it’s just a quiet fan — she’s already feeling the difference. ->I have replaced the filter and it works, but on the app it still shows as 100% used up. Its a common error on xiaomi air purifiers. Coway is overall a better air purifier. Easy to clean pre filter as well. The minus with lower models of coway is that you cant tell the exact aqi
r/Frugal_Ind • Got an air purifier for my mom (64), told her it’s just a quiet fan — she’s already feeling the difference. ->It doesnt always show. It shows after the first filter id actually nearly 100% used up. Its a glitch. After the first time when you change the filter, it will still show the new filter as 100% used up. Eventually, how will you know the new filter is not working? The air wont be cleaned, and aqi will not reduce. Some people have found a solution to this glitch: https://www.reddit.com/r/AirPurifiers/s/aB9p9lqrx2
