XiaomiMi Air Purifier 3H, True HEPA H13 3-Stage Filter System Removes 99.97% of Pollutants as small as 0.3 microns, Smart Home Integration, Whisper Quiet, Just 0.9KW/day, OLED Touch Display

PROS:- I set the unit in a central area of the house between the living room and kitchen so that it can cover multiple areas. On auto setting, it kicked on very quickly to remove polluted air and any smoked from cooking.- After a few months of usage, I've noticed a considerable difference in the overall reduction of dust and my seasonal allergies have been noticeably reduced.CONS:- When the fan kicks on to maximum, the fan noise is noticeable. When operating under low or medium speeds, it's fairly quiet.- Smart app instructions included for troubleshooting were lacking. I couldn't get device to detect & connect to my WiFi. After doing some research on Reddit, I found that changing the router encryption setting from WPA-PSK/WPA2-PSK to WPA2-PSK solved the problem.- May encounter issues when trying to sync Google Home with Mi Home app.TIPS:- I recommend buying disposable filter cloths to wrap around the unit's filter. It should prolong the life of the filter and keep it clean...and perhaps save you money in the long term. https://www.amazon.com/DHVIJA-Compatible-Anti-dust-Kimberley-Electrostatic/dp/B0BKLJK242/ref=sr_1_5?crid=9XTUY16470H8&keywords=xiaomi%2B3h%2Bair%2Bpurifier%2Bfilter&qid=1683256753&sprefix=xiaomi%2B3h%2Bair%2Bpurifier%2Bfilter%2Caps%2C156&sr=8-5&th=1

I have two of these filters – one for home and another for a vacation apartment. The best features include the ability to track the actual air quality (by number) and control multiple devices from your phone anywhere. This is especially helpful when spending time in an area with terrible air quality due to pollution, as it allows you to monitor and maintain healthier living quarters. My only complaint is I believe there is a fan which draws air to the sensor even when the device is off. It has begun to make a buzzing noise while on and off on occasion. The solution would be lubricating it.

Love this! Great quality, but only uses proprietary filters that are recognized by chip. Otherwise 5 stars.

Very good quality. It has different noise level options and easy to use.

Excelente producto. Nada ruidoso y muy funcional.

It’s the third air purifier brand I have used. This one is much better than many other big names. Easy to set up, pretty sensitive & accurate pm2.5 monitors, low noise level.

I had one when I lived in Beijing…now that smoke is coming to the US from Canada, I knew exactly what to buy!

Es un malísimo producto no vale para nada solo saca aire y no tiene nada de poder de subcion vamos que es horrible
