Xiaomi - Xiaomi Smart Air Purifier 4 Pro

It’s getting real crazy today. My Xiaomi 4 pro is reading 16 at full speed after many hours and SND WAY reader 35. It was 03 and 06 earlier

I've had the Xiaomi Smart 4 Pro about a year now; I'd compare it to an Apple experience. The app is slick and stable, the features are satisfying and there's plenty to tweak for automation and comfort. The modes are fine, not disturbing in sleep. AQI readings, temp and humidity in the app and on the display. Simple setup, takes a few minites and is pretty direct. The performance is...fine. The filter lasted a full 10 mo/s of 3hr/full and bedtime mode/overnight daily. Electricity cost is minimal. Filters are ¥400 and have an rfid encrypted chip so you MUST buy one from Xiaomi. They also 'activate' once swapped out so when the xiaomi app says you have 0% life and need to change that's the end of the discussion. you can't just hose it down and dry it off. Same BS as most ink cartridge manufacturers. Kind of them to send a notification toast gor the xiaomi.com store page to purchase directly. The pocket looters even ask if you want to automate purchases for filters in the future. Bumped it when cleaning once and knocked it over. It wouldn't register a proper seal on the back door after and became useless. I contacted customer care through the app. Only moderately annoying (full language barrier). They sent a tech out to collect it, repair it, and return it pro bono within 72 hrs. I believe the warranty is a year or something. ¥1200 for the 4 pro model. Apartment is 25sq/m and consistently sits at ~005 (PM2.5/m^3). So yeah. It's fine. It's the Apple experience. Pay more, get premium-skinned ego boost with a dash of convenience.

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.

I have one of the Chinese xiaomi large format ones, keeps all the dust particles out of the air. You can see the difference in the sunlight. Air purifier pro 4. Strongly recommend, does my kitchen/dining/lounge area no problems. 100m2 ish.

you need a better or larger capacity purifier. Mine stays single digits

I have had my Xiaomi 4 pro for years. 50sq/m and even with this bad air. It stays single digits. Right now at 3. My buddy has the smaller unit for same size condo and his runs double digits.

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.

why not go for airmega 250 coway instead of 150? It has bigger coverage and it would better cover your bedroom space. If considering Xiaomi, go for simple 4 (not the pro) since pro has ionizer which generates ozone ( not good) philips- not sure how is the filter availability situation presently but I have heard in the past replacement filters were not available easily Qobo- no idea Dyson- not needed, coway or Xiaomi can clean the air as good as Dyson

I added all my Xiaomi ones - 1st gen, 2nd gen and 4 Pro - to Apple Home via Homebridge. Kinda straightforward and expose data like temperature, humidity, air quality to Apple Home too.

Mine is MI air purifier 4 and i have seen reviews of it that it gets dirty very fast. Idk maybe my room is cleaner than i expected

I second that. I use the Xiaomi 4 Pro and it gets the job done. High airflow, low noise level and HEPA filter quality.
