This intelligent air purifier should clean the atmosphere in spaces up to 1,733 square feet as little as an hour. The Core 400S has a cylindrical shape with vents at the top and a touch screen that shows air quality readings. You can have an idea of ​​the current air quality in your space at a glance with a ring that changes color that lights up in blue, green, orange or red. The 360 ​​-degree filtration system would be able to capture more than 99.9% of pollutants as small as 0.3 microns, such as dust, animal squams and pollen.

There is an automatic mode which should be enough to maintain air quality, but the Core 400S is also compatible with the Alexa and Google Assistant voice controls. The fan is not too strong, even when it operates at a maximum speed – the volume fell on 62 dB in our tests. Meanwhile, at $ 50 each, the air filter replacements are not too expensive compared to those of many Levoit competitors.
