Xiaomi - Smart Air Purifier Pro 4

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 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 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.

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

Got the Xiaomi Air Purifier 4 Pro for my living room. Worked great for fine dust. Not much for cat hairs due to small intake holes

Looks interesting, but not as widely available as a Xiaomi. The Xiaomi 4 Pro and the Smartair SA-600 appear to have the most directly comparible CADR ratings (500 vs 508 claimed) Prices are from Lazada Xiaomi store or WEDO air, an official supplier of SmartAir in Thailand [SmartAir SA-600 Review](https://housefresh.com/smart-air-sa600-review/) Cost: 10900 [Xiaomi 4 Pro](https://housefresh.com/xiaomi-4-pro-review/) Cost 7010 SmartAir Replacement Filter cost (Requires 2X HEPA plus 2X Carbon) 990+890= 1880 Xiaomi Replacement Filter cost (1 HEPA, with built in Carbon filter) 1349 The SA-600 is fully manual, basically a box fan with a filter. The Xiaomi has an air quality meter and an auto mode.

I have Xiaomi Air Purifiers in each room. Big one for living room, smaller ones for smaller rooms. My particle sensitive partner (allergies & athma) feels the difference Edit: as for why I trust it, did my share of research at the time, like airflow and all. Beside that, the Pm5 score readings have been very reliable, reflect every messy event in the house, the level of pollution when we open the windows, and goes down steadily when we close all doors&windows. New filters can be ordered on Lazada btw

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'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.
