Looking for a clean home? Then the Xiaomi Smart Air Purifier 4 is the air purifier you need. With this powerhouse, you'll enjoy optimal air quality. In about 10 minutes, it is able to purify a 20 square meter room of bacteria, pollen, dust mites, cooking fumes, unpleasant odors and other annoying pollutants. It does this with a precision of 99.97%. Thus, the Xiaomi Smart Air Purifier 4 removes virtually all harmful particles and airs the house thoroughly. But more importantly, you breathe a sigh of relief again.

With an air intake of 360° and an effective coverage area of 48 square meters, it delivers up to 6660 liters of clean air per minute. This yields a CADR of 400m³/hr and an FCADR of 150 m³/hr. Coming home to a fresh house? With smart controls via the Xiaomi Mi Home app, you'll ensure a fresh home on the go when you arrive. You also control the Purifier 4 with your voice via Google Assistant or Amazon Alexa. 

The Xiaomi Smart Air Purifier works with air ionization. This works as follows: all over the house there are small particles floating, such as foul odors, dust and pollen. One visible, the other invisible. The ionizer from the Xiaomi Smart Air Purifier 4 blows out negatively charged ions. These ions attract all the small particles, make them heavier and cause them to fall. The particles settle on the ground or on furniture, leaving you with only clean air to breathe.

Compact and durable

With a size of 25x25x55.8cm and a weight of 5 kilograms you can effortlessly move the cleaner around the house. Thanks to the OLED touch screen you keep an eye on everything: there you can see the current PM2.5 value, temperature, humidity and the Wi-Fi status. You control it with the on-off button and the fan speed button, where you choose from 6 settings. Is the air value at the desired level? Then the cleaner automatically hits sleep mode.

Good against allergies

The Xiaomi Smart Air Purifier 4's huge filter cleans your home of a range of substances, smoke and mold. It also gets rid of nasty odors, such as those from your dog or cat, a burnt meal or frying smell. For people who are prone to allergies, such as pollen from hay fever, the air purifier is also a godsend. Just like for people who are allergic to pet hairs and dander, because it also removes them from the air.

Cleaning the air purifier is easy: you unscrew the grille, clean the air ducts and fan blades with a soft cloth and screw the grille back into place.

Low-noise: for a good night's sleep

If you plan to use the air purifier in a sleeping area, this device is a perfect choice: with a low-noise level of 32.1 decibels, you close your eyes undisturbed. Meanwhile, the Smart Air Purifier 4 continues to freshen the air in the bedroom, so you wake up in a completely clean room!
