Our Verdict

It is a largely generic air purifier designed for small areas, however its sensible options work nicely and it’s priced to maneuver.

You’ve seen this product earlier than, I’m positive, or a minimum of one thing almost similar to it. It’s a compact, no-frills air purifier that’s straightforward to maneuver wherever you want it. So, what makes it totally different?

Xiaomi produces a variety of bigger air air purifier merchandise, with this member of its Compact line designed for tighter areas. The cylindrical, all-white gadget is a mere 14 inches excessive and 9 inches throughout, and it weighs barely lower than 5 kilos. A cylindrical filter (which slides in via the underside of the air purifier) will not be a HEPA filter however relatively a proprietary filter created from “melt-blown PP fibres with electrostatic know-how” as a substitute of the customary fiberglass utilized in HEPA designs.

This evaluate is a part of TechHive’s in-depth protection of the best smart air purifiers.

Xiaomi says its filter works higher than HEPA, and whereas I’m undecided if that declare is definitely verifiable, Xiaomi’s acknowledged specs are roughly on par with these of HEPA-based purifiers with related energy. Particularly, the corporate claims a CADR (clear air supply charge) of 135 cubic toes per minute for particulates (no breakdown past that) and boasts a most protection space of 516 sq. toes. That’s a powerful CADR given the small measurement of the gadget.

Operationally, the gadget could be very easy, with air pulled in from the bottom and emitted upwards via the highest. A management panel is centrally mounted on the highest panel, with three primary capabilities: energy, a light-adjustment button, and a button that permits you to swap between automated, sleep, and guide modes. You’ll be able to’t change the ability of the guide mode on the gadget itself; for this, you’ll want to make use of the Mi Dwelling cell app, the place a slider allows you to modify the fan velocity to your liking. The button on the {hardware} itself merely selects the newest velocity you’ve chosen inside the app.

The air purifier {hardware} additionally consists of one further characteristic: a color-coded air high quality indicator that may show one among 4 ranges of PM2.5 focus, starting from inexperienced (finest, lower than 35 ppm) to crimson (worst, greater than 150 ppm). Filters are rated to final 6 to 12 months; alternative prices haven’t but been introduced.

Connecting the Xiaomi air purifier to your property community is simple. The Mi Dwelling app discovers the gadget mechanically through Bluetooth, after which rapidly bridges it rapidly to your 2.4GHz Wi-Fi community. As famous above, the app affords extra fine-grained guide controls, plus a set of further options, together with a baby lock, a easy scheduling operate, and a extra complicated “Sensible Scenes” characteristic that permits you to arrange multi-device automations if in case you have a couple of piece of appropriate tools.

This IFTTT-like system allows you to hyperlink tools collectively nonetheless you’d like; for instance, activate a lightweight when the air purifier is working. It’s also possible to schedule automations, however for most individuals, the usual scheduling possibility ought to be loads. Curiously, no countdown timer is obtainable within the app, nor are there any long-term logging options. You’ll be able to, nonetheless join the gadget to Alexa or Google Dwelling, permitting for extra tweakability.

At full velocity, the Xiaomi air purifier is loud however by no means deafening, and at wherever lower than half-power or beneath it’s largely unnoticeable. Higher nonetheless, with a road worth of about $100, this is likely one of the extra inexpensive purifiers available on the market, significantly amongst these with sensible options. Whereas I can’t touch upon how efficient its proprietary filter is in relation to a real HEPA filter, it does a minimum of appear to be efficient, and its specs are spectacular. Whereas claims of being “higher than HEPA” are at all times a bit fishy, I’ve no motive to imagine this gadget doesn’t a minimum of work in addition to one.
