Xiaomi Smart Air Purifier 4 Lite - 360m3/ h CADR

Xiaomi Smart Air Purifier 4 Lite lists a particle CADR of up to 360m3/h, an effective coverage area of 25-43m2, and power as low as 33W on Xiaomi's US product page. The same page lists 33.4dB(A) in Night Mode and a 6-12 month filter life.

Key Numbers On The Shelf

The US product page names the model as Xiaomi Smart Air Purifier 4 Lite and shows a three-in-one filter, 99.97% filtration of 0.3?m particles, and Wi-Fi app control through Mi Home/Xiaomi Home. It also lists voice control support for Google Assistant and Alexa.

The specs page adds the product model AC-M17-SC, dimensions of 240 x 240 x 533.5mm, and a net product weight of approximately 4.8kg. Xiaomi's filter page says the replacement filter is only compatible with Xiaomi Smart Air Purifier 4 Lite and recommends replacement every 6-12 months.

What The Box Includes

Xiaomi's global specs page lists four items in the package: Xiaomi Smart Air Purifier 4 Lite x1, filter x1, power adapter x1, and user manual x1. The US product page also highlights TÜV Rheinland Allergy Care Certification and a base area smaller than an A4 sheet of paper.

Compared with the older Xiaomi Air Purifier 3C, the 4 Lite page says the filter's activated carbon content is 450,000mg versus 250,000mg on the standard filter used with the 3C. The same page says the 4 Lite filter uses electrostatic charge and mechanical filtration.

Placement In Xiaomi's Lineup

Who It Fits Best

The published numbers point to a room purifier for medium spaces, with 25-43m2 coverage, 33.4dB(A) Night Mode, and filter reminders in the app. For buyers comparing purifier specs, the 4 Lite sits with coverage and noise figures that stay easy to scan.

The US page also says the purifier can reduce H1N1 virus in the air and shows real-time PM2.5, temperature, humidity, and Wi-Fi status on the LED display. Those readings keep the model focused on air quality monitoring as much as airflow.

Bottom Line

Xiaomi Smart Air Purifier 4 Lite is a compact Wi-Fi air purifier with a documented 360m3/h CADR, 33W power draw, and a package that includes the filter, adapter, and manual. Its strongest case is for rooms inside the 25-43m2 range and users who want app control plus a visible air-quality readout.
