Good to know
All models are compatible with Google Assistant, Alexa and the Xiaomi Home app. The CADR value (m³/h) shows how much air is cleaned per hour. The higher the value, the faster the air is clean.

How to choose the right model

1
Work out the room size Measure the floor area of the room in m². For open-plan living areas, count the whole connected area.
2
Pick a model with a matching area Your room should fall within the area rating. If it is near the upper limit, go for the next larger model. It cleans the air faster.
3
Compare the features Are allergens, smoke or formaldehyde important to you? Then look at sensors and displays such as the allergen display or the formaldehyde sensor.
4
Check availability You can see whether a model is in stock on its product page in the online shop. Not every model is listed there.

Frequently asked

What does the CADR value mean?
CADR stands for «Clean Air Delivery Rate». It shows in m³/h how much clean air the device delivers per hour. The higher the value, the faster the air in the room is cleaned.

Can I use a model for a larger area in a small room?
Yes. It will then clean the air particularly fast. The area rating is the upper limit up to which the device reliably covers a room.

Which model is suitable for allergy sufferers?
The Smart Air Purifier 4 Pro has an allergen display. An air purifier is not a medical device, though. For severe allergies, please also seek medical advice.

How do I control the air purifier?
Via the Xiaomi Home app or with voice commands through Google Assistant and Alexa.

How often do I need to change the filter?
That depends on the model and how you use it. You can see the filter status in the Xiaomi Home app. You will find replacement filters in the online shop, if they are listed there.

The model is sold out. Is there an alternative?
Take the next larger model from the overview above. Unfortunately, we cannot give an exact date for when it will be back in stock.

My air purifier is not working properly. What now?
If there is a defect, we will check for a warranty case. For this we need the proof of purchase, the exact model name, the serial number and a description of the fault.
