Xiaomi has long been a trailblazer in the world of affordable yet high-quality tech, and their Smart Air Purifiers are no exception. With the latest 4 series, the Chinese powerhouse has not only built upon the strengths of previous generations, but has also taken a turn for the sensible with their model names. As a proud owner of the Xiaomi Mi Air Purifier 3H for the past two years, I can attest to its effectiveness in making a tangible difference to the air quality within my personal sanctuary. My own anecdotal evidence suggests that this unassuming corner dweller has helped alleviate my asthma symptoms and proved to be a trusty ally when it comes to banishing pesky soldering odours from my makeshift lab.
Introducing the Xiaomi Smart Air Purifier 4 line-up
In a refreshing move towards simplicity, Xiaomi has christened its latest generation of air purifiers under the unified name: Xiaomi Smart Air Purifier 4. The line-up consists of three distinct models, each tailored to fit different needs and budgets: First up is the Xiaomi Smart Air Purifier 4, the worthy successor to the popular Xiaomi Mi Air Purifier 3/H. For those seeking a more budget-friendly option, the Xiaomi Smart Air Purifier 4 Lite offers a slightly pared-down experience while still retaining the core functionality, making it a comparable alternative to the Xiaomi Mi Air Purifier 3C. Finally, for larger spaces in need of a breath of fresh air, the Xiaomi Smart Air Purifier 4 Pro has you covered.
Xiaomi Smart Air Purifier 4: Bigger, better, and fresher
The Xiaomi Smart Air Purifier 4, a tad larger than its predecessor, boasts dimensions of 250 × 250 × 520 mm. This slight increase in size brings with it a welcome 5% boost in Clean Air Delivery Rate (CADR) to 400 m³/h, while reportedly consuming 20% less energy and producing less noise.
Xiaomi introduces a new filter exclusive to the Smart Air Purifier 4, which features a thicker layer of activated carbon and their proprietary High-Efficiency Filter. This design allows for improved airflow, resulting in quieter and more efficient operation. Remember to change the filter annually, and double-check that you're purchasing the correct one.
While not exactly repair-friendly, the Xiaomi Smart Air Purifier 4 is at least easy to clean. The fan grill on top can be removed without fumbling with tabs or screws, making the device's insides accessible for maintenance.
The Xiaomi Smart Air Purifier 4 will be available in the Swiss Xiaomi store from March, priced at CHF199 (~US$220) including taxes.
Xiaomi Smart Air Purifier 4 Lite: Compact and budget-friendly
The Xiaomi Smart Air Purifier 4 Lite stands a mere centimetre taller than the Mi Air Purifier 3/H and offers a more wallet-friendly alternative to the base model. It omits the negative ion generator and has a slightly lower CADR of 360 m³/h. Similar to previous budget models like the Mi Air Purifier 3C, you'll need to remove the top compartment to access the filter. The 4 Lite also introduces a new and unique filter model.
The design of the 4 Lite leans towards a boxier shape with subtly rounded edges, and Xiaomi's logo is now displayed prominently on the front. The OLED screen found in the base and Pro models is swapped out for a basic seven-segment display, reminiscent of an alarm clock, featuring capacitive buttons.
The Xiaomi Smart Air Purifier 4 Lite will be available in the Swiss Xiaomi store from March, priced at CHF169 (~US$183) including taxes.
Xiaomi Smart Air Purifier 4 Pro: The ultimate powerhouse
Completing the lineup, the Xiaomi Smart Air Purifier 4 Pro is the biggest and priciest of the three models. With dimensions of 275 × 275 × 680 mm, this powerhouse is designed to purify vast spaces or large rooms up to 60㎡, thanks to its impressive CADR of 400 m³/h.
The 4 Pro is essentially an upscaled version of the base model, sporting a similar design and featuring a negative ion generator. Moreover, it's more efficient and quieter in operation compared to previous Pro models.
The Xiaomi Smart Air Purifier 4 Pro is available in the Swiss Xiaomi store for CHF299 (~US$325) including taxes.
Is the Xiaomi Smart Air Purifier 4 worth the switch?
Deciding to upgrade from your current air purifier to the Xiaomi Smart Air Purifier 4 boils down to two key considerations: the allure of the negative air ion generator and the prospect of quieter operation. If these features are on your must-have list, then the 4 series may be the perfect fit for you. However, if you're content with your existing Mi Air Purifier 3H, like me, it might be worth holding onto it for now.
