Best for: Households wanting an app-connected air purifier for medium-sized rooms that integrates directly with Google Home or Amazon Alexa setups.
The Smartmi Air Purifier C1 (model KQJHQ01ZM) is a freestanding indoor air treatment unit suited for floor areas between 26 and 48 square metres. According to Smartmi documentation, the unit delivers a Clean Air Delivery Rate (CADR) of 400 m³/h for fine particles and 60 m³/h for formaldehyde. Air cleaning relies on a three-stage mechanical filter consisting of a primary PET pre-filter, an H13 True HEPA layer designed to trap 99.97% of particles down to 0.3 micrometres, and an activated carbon stage to address odours. The cylindrical body houses dual laser sensors that analyse PM2.5 and total volatile organic compounds (TVOC), displaying real-time readings on an integrated digital display.
This purifier suits Australian households looking to automate allergen and dust filtering across bedrooms, home offices, or living areas without paying ongoing app subscription fees. Smart controls run through the standard Xiaomi Home ecosystem, allowing automated fan-speed adjustments based on measured air quality, timer scheduling, and remote monitoring. It also suits homes using Google Home or Amazon Alexa voice setups, as both ecosystems link directly to the Smartmi integration. However, buyers prioritising Apple HomeKit or Matter should look elsewhere, as official documentation confirms no native integration for these protocols. Similarly, users on mesh networking setups that cannot separate or assign a 2.4 GHz band may experience onboarding issues.
Retail listings from Australian stores including JB Hi-Fi, BIG W, and Mobileciti confirm the Smartmi C1 ships with a 12-month local warranty. According to the technical manual, the unit operates on a wide input voltage of 100–240 V at 50/60 Hz with a rated power consumption of 40 watts, matching Australian mains electricity specifications. The unit uses a detachable power cord. Note that manufacturer documentation does not explicitly detail whether the packaged lead carries an AS/NZS 3112 Australian three-pin plug, so check the supplied cable upon arrival.
Networking is restricted to 2.4 GHz Wi-Fi (802.11 b/g/n), meaning your home router must broadcast on this frequency during initial pairing. While native smart home support is limited to Xiaomi Home, Alexa, and Google Home, the Home Assistant community provides local integration for this model via the Xiaomi Miio platform.

Seems to be pretty good. New filters are around £25 which is cheaper than many other models. You need to install the Xiaomi app on your phone to use all the various fan speeds. Just from the device you get Auto, Sleep an ...
