Gadgets: Smartmi Air Purifier 2 is a user-friendly home-use device that eliminates bacteria


Published in Science & Technology News

Without being a medical professional or making any bold predictions, an air purifier is probably an essential gadget we can add to the house. The Smartmi Air Purifier 2 is a user-friendly home-use device to clean the air of pollutants.

The free-standing, vintage blue-colored cylinder with air vents measures 10.2-by-22.1 inches and weighs 12 pounds. The AC-powered device does high-efficiency air scrubbing for up to 484 feet of cleaning area, removing airborne particles 0.08 micrometers in size.

The air purifier set at high can clean the area and remove airborne particles in the time it takes an average person to change their T-shirt, according to Smartmi. The size makes it ideal for living areas, bedrooms, workspaces and classrooms.

The need for a small home appliance such as the Smartmi Air Purifier 2 is explained by Smartmi, “As both the number of indoor and outdoor allergens increases, it’s difficult to locate individual allergens quickly and remove allergen effectively, making the need for an Allergy Care Certified air purifier in your home even more important.”

There’s not a lot to it. It’s essentially just a plug-and-play, self-contained unit and comes fully assembled. Once powered on, it provides a unique UV sterilization process that eliminates bacteria and viruses.

The five significant points supplied to me from Smartmi, which measure and determine air quality, are PM10, PM2.5, TVOC, temperature, and humidity. For those wanting technical data, the Smartmi website has specifics on pollutants captured and the size of the particles. A top-sided OLED touch screen displays the room temperature and air quality in real-time. It has a power button and cycles through auto, favorite and sleep modes. A pollen indicator shows those levels for allergy sufferers. An included AC power cord plugs into the back.

It’s not a device where you will get instant results, like great-tasting french fries from an air fryer (more about that in a few weeks). But instead, it’s working in the background, in silence, eliminating the dangerous aspects of the air that could make you sick or set off allergies.


Inside is a high-quality H13 true HEPA filter and is the key to the system that includes pre-filter and the high-efficiency activated carbon filter for capturing 99.98-percent of airborne particles and 0.3um allergens. This includes dust, pollen, pet dander and smoke.

In addition, a UV sterilization light eliminates items such as bacteria and viruses. Those who don’t want the UV sterilization can turn it off with the Smartmi Link app. The whisper-quiet Smartmi Air Purifier 2 uses 40 watts of energy and has noise levels ranging from 30dB to 64dB.

The app allows for powering the Smartmi Air Purifier 2 on and off, choosing the modes, and turning the UV lamp, sound, and child lock on or off. Displays for the air quality, indoor temperature, and humidity are also on the app.

A top grille is easily removed to clean dust buildup quickly. A percentage shows the primary filter's lifespan on the display. When the filter has less than a 10% lifespan, the display shows a QR code for a replacement ($49.99 at Amazon). A backside hatch opens to remove the filter.

The Smartmi Air Purifier 2 works with Amazon Alexa, Google Assistant and Apple Homekit smart home assistants, along with the free Smartmi Link app. $259.99
