  • All generations of the Air Purifier comes with the same white color good quality plastic exterior and they all look the same except for subtle differences. The Xiaomi Air Purifier 3H is shaped like a long rectangular cube. It has mesh-like perforations on all sides. But these holes do not mess with the aesthetics one bit. It’s designed in such a way to attract bad air from all sides of the device and the top air diffuses the cleaner air.
  • It is a very lightweight device so its easy to lug around the house if you want to clean the entire place.
  • The major noticeable difference between the Xiaomi mi air purifier 3H and its predecessors is the circular OLED panel on the exterior of the Mi Air Purifier 3H.
  • If you're wondering, if this device will suit your decor or not, the answer is an absolute yes. It’s a non-obtrusive piece that will blend well in any setting.

Function and Use

The Mi Air Purifier Price and Review wouldn't be accurate with the installation process. It's super simple to use.

  • Once you plug it into a socket, the LED screen lights up.
  • Just press the touch button it till it turns on.
  • You can then connect it to your phone via WiFi and control its various settings.

This is not only a pollutant remover but also removes any bad smells in the environment.

  • Most of you might be worried if whether this thing can actually filter air. Fortunately for you sceptics out there. Once you sync the device to your Phone. You can literally see the graphs on the Mi Home App.
  • The LED screen glows green if its in a clean environment and red if its in a polluted area. The LED display also shows you the temperature and humidity.
  • For normal situations, the Auto mode is suggested. It basically absorbs the bad air from the three sides. This is slightly different from the normal air purifiers that absorb air only from one side.
  • Now, this makes it pretty special, because if you keep it next to where your sitting, you will have 360-degrees of protection and clean air.
  • Inside the purifier are three layers of absorbents. The first absorbent sucks out all the small particles in the air, that goes straight to your lungs.
  • The second absorbent removes and bad smells in the vicinity and the third absorbent removes any formaldehyde from the air around you.

The best part? If you are allergic to stuff like pollen, pet fur, or other irritants, this Air Purifier will clear it out.


When it comes to the performance, all I can say is that the Mi Air Purifier 3H does an amazing job. All you have to do is put it in auto mode and it automatically detects the dust and particulate matter around you. It efficiently filters out the PM 2.5, making the air pristine and fresh.

It is equipped with this centrifugal fan that has been through multiple refinements when compared to its predecessors, making it not only faster but also effective. The custom brushless motor supports the purification process and reduces wind resistance. This improves airflow and thereby the effectiveness.

All of this helps bring down the particulate matter in a matter of minutes. From what I've seen It can effectively filter 6333 liters of clean air per minute with a Clean Air Delivery Rate (CADR) of 380 m³/h. This is at least 30% better than its predecessors.

Although its performance is stellar, you won't feel an amazing change in the room. You might feel the "lightness" in the air. But that's mostly your imagination. Don't get me wrong it does an amazing job. However, you'll have to test it out with various equipment to see the difference. A lot of people also misunderstand the nature of this device and expect it to cool the air as well, this is false.

Xiaomi Purifier Filters

As the filters inside get mucky due to the pollutants sticking to them, they need to be replaced, they ideally should be replaced once in 6 months. They can be bought easily, but are a tad expensive.

  • It also is one of the quietest air purifiers out there.
  • Why is this important? Try sucking in air through your nose. That sound of suction is pretty loud. But this thing is so quiet. This makes the Mi Air Purifier Top Class.

This HEPA filter is extremely effective when it comes to purifying polluted air. It removes 99% of dust, pollen, smoke particles, and other forms of fine particulate matter. However, what you're paying for is its ability to get rid of micro allergens. If you or your family is sensitive to allergies and common airborne allergens, this Xiaomi purifier can do wonders for you.

This Air Purifier shows the air quality in a room and even has color-coded values to point out the danger level and safety levels. This device can cleanse the air in a good 40-45 minutes. If it's a closed room you can notice the difference. especially if it's an odor-based pollutant.

This 3rd edition is also equipped with a new centrifugal fan that can cleanse 380 cubic meters of air every hour. It is also a relatively smart device. For example, it'll go full power during the initial cleanse and then efficiently allocate energy to conserve battery life. So, it essentially ends up saving you money as well.

The filter is something you're going to have to change regularly. The HEPA filter can last for a good 3 months in a heavily polluted city.
