The Zigma Aerio-300 Air Purifier

I’m a heavy smoker, and, despite placing three small air purifiers in critical locations, my house stinks of cigarette smoke.

If all three devices were permanently running at their highest speed, they could cope. That, however, would significantly increase noise pollution within the house and necessitate more frequent filter replacements.

I felt the better solution would be to replace one of the small air purifiers with a high-capacity unit that automatically adjusted its fan speed according to the surrounding air’s quality. I planned to run this device continuously, maintaining clean air within the entire house while using the smaller air purifiers only when smoking in the same room.

While conducting my search for the new device, I added two additional requirements. I wanted an air purifier fitted with a long-life filter and the ability to be controlled by voice commands.

Today I am taking a close look at Zigma’s Aerio 300 Air Purifier.

The Aerio 300 is 7.9 inches deep, 13.4 inches wide, and 19.5 inches high. It is composed of white plastic. Air is sucked in from the front, drawn through an H13 HEPA 3-Stage filter, and then exhausted through the top of the device.

The control panel includes a button that turns on the device. It is also used to select one of three possible fan speeds or set the air purifier to automatic. The device continuously monitors air quality in automatic mode and uses the result to adjust the air purifier’s fan speed. The color of the rim light surrounding this button indicates the local air’s purity.

A second button turns on the negative ion generator and the ultraviolet lamp. The device will go into sleep mode, turning off all lights when the third button is pressed. If this button is held for three seconds, the air purifier enters child lock mode.

The Zigma application sets up the various options of the air purifier and allows remote control. It also facilitates voice control using applications such as Alexa, Siri, and Google Assistant.

The Filter

The Aerio-300 is fitted with an H13 True HEPA Filter. It is designed for large rooms and can capture up to 99.97% of airborne particles. This includes dust, pollen, pet dander, pet hair, smoke, and household odors.

The filter pack consists of a washable foam pre-filter that captures large particles such as pet hair. Velcro is used to attach it to the primary filter, which includes both HEPA and carbon filtration elements. This filter must be replaced every six to eight months.


This air purifier has a CADR (clean air delivery rate) of 1580 sq ft. CADR refers to the amount of air cleaned of particles sized 0.3 microns or larger within one hour. The coverage provided by the Aerio-300 is more than enough to handle the bottom floor of my house.

Noise Level

Size does matter. My Levoit air purifier is very effective, but because its filter and fan are compact, the fan must rotate very quickly. This device is annoyingly noisy when running at anything above its lowest setting.

The Aerio 300, with its larger filter and fan, generates significantly less noise than the Levoit while cleaning a greater volume of air. Noise levels range from 24 – 48db.

This device is whisper quiet at its lowest setting. It can be heard from across the room at the second position but is not particularly bothersome. Like all its competitors, the Aerio-300’s noise level is relatively high at its maximum setting.


Negative Ion Generation

This air purifier may be used to generate electrically charged molecules which research suggests can produce a positive effect on your health. A button at the top of the Aerio-300 activates, in concert, both the negative ion generator and the UV-C light.

Ultraviolet Light

UV-C light with a bandwidth of 200-275nm is produced within the air purifier. This radiation disrupts the DNA of viruses and bacteria, halting their ability to replicate and multiply.

Air Quality Sensor

An AI controllable air purifier such as the Aerio-300 utilizes air quality sensors to determine the condition of the surrounding air. If, when the air purifier is set to auto mode, the air quality is poor, the fan’s speed will increase. As the air quality improves, the device will decrease the fan’s rotation rate. This type of system will reduce power use and keep noise levels to a minimum.

The air quality is reflected by the color of the light ringing the Aerio-300’s power button.

Voice Control

Alexa, Siri, and Google assistant can be utilized to control this device. I found it surprisingly easy to set up and use Alexa.

Alexa is a very handy assistant. Every evening as I head off to bed, I use the command “Alexa, good night.” Alexa wishes me a pleasant night and turns on the upstairs lights. She also turns off the air purifier and another set of lights downstairs.

Zigma Application

The Zigma application controls the air purifier and adjusts its settings. This allows a smartphone to be employed as a remote control.

Overall Impression

The Aerio-300 is the most sophisticated and powerful air purifier I have tested. It can easily handle a large room and is capable of maintaining the air quality of several connected rooms.

Its large fan and filter enable this device to maintain a noise level lower than most of its competitors. However, like all air purifiers, it is pretty loud at its highest setting.

The Aerio-300 features additional protection in the form of a negative ion generator and UV-C light. I especially appreciate the ability to turn this device on and off using Alexa.

This air purifier’s most helpful feature revolves around its ability to automatically adjust its fan speed in response to the changing quality of the air. I recommend the Zigma Aerio-300.
