Zigma’s Smart Aerio 300 comes with a talk on an artificial intelligence algorithm and air quality forecast, but let’s get down to the brass tacks – this is a relatively basic, lower-cost air purifier with simple and smart smart features. Simple design, built with smaller rooms in mind.
The unit is small, weighing 13 pounds, and measuring just 20 x 12 x 8 inches (HxWxD). Air is drawn in through the entire front face of the device, which is covered by a stamped plastic grill, is passed through a HEPA H13 filter, and is emitted through the top of the device. Basic controls are available here, including a power button that toggles between four speed settings (the last being a tagless auto mode), a sleep button and child lock, and a button that turns on negative ion filtration and UV-C (together).
This last feature activates both an ionizer and an internal UV bulb; they cannot be activated individually. A ring of light surrounding the power button glows according to the air quality, with four levels of PM2.5 concentration indicated.
This review is part of TechHive’s coverage of the best air purifiers, where you will find reviews of competing offerings, as well as a buyer’s guide on the features to consider when purchasing this type of product.
One feature that immediately turned me off was the fact that the Smart Aerio 300 beeps every time a button is pressed, any button, even when it goes into sleep mode. It is an unnecessary feature in an air purifier where visual cues indicate each setting change and cannot be disabled.
Filters are rated to last 6 to 9 months; replacements are currently $ 38 (on sale), or you can upgrade to an H14 filter for $ 56. It’s also worth noting that Zigma suggests cleaning the UV-C bulb every 6 months, but it’s unclear where this is located bulb internally or how you are supposed to clean it. Clearer instructions are needed on this front.
Zigma sets a one-time CADR rate of 194 cubic feet per minute, which is low but probably good for a smaller room. The maximum coverage capacity is specified at 430 square feet, but Zigma also suggests that you can clean 1,580 square feet in an hour, which is probably only true if you’re counting multiple scrubs of the same space. The unit is not particularly loud even at its highest settings, emitting 48 dBA per Zigma. In its quietest modes, the unit is virtually silent, at least as long as you don’t press any buttons.
Getting the unit on my Wi-Fi network (it supports 2.4GHz networks only) was quick, and the process involved scanning a QR code on the back of the unit and going through some basic setup steps. Wireless stability was fine, with no disconnects found. Zigma’s mobile app is pretty primitive, though it does offer a look at local outdoor weather conditions (metric only), as well as a numerical measure of indoor PM2.5 levels and a filter life rating.
Manual controls are recreated here, the unit still sounds when you change a setting even in the app, just like a programming system. Programming with Zigma is an unintuitive operation, built around a kind of if-then structure that even seasoned professionals will need some getting used to.
Overall, there is nothing particularly unique about this purifier, and if it were at least a little more attractive, it might be worth considering for those looking for a basic unit to clean a bedroom or kitchen setting. As is, it will probably fit better in more industrial settings.
