The Kyvol Air purifier

The Kyvol Air purifier

I’m a smoker. And since I live alone, I can get away with lighting up at home. Unfortunately, smoke tends to add a yellow tinge to walls, and visitors often complain about the unpleasant odor that hangs around the house.

To fight this, I’ve installed air purifiers in my office, kitchen, and living room. Due to the recent purchase of a projector, I now require another of these devices in my dining room. Because I plan to sit close to the device, it must be both effective and quiet.

Today I am examining an air purifier manufactured by Kyvol.



The Kyvol air purifier is composed of gray plastic with black accents. It is 8.5 inches wide and 15 inches tall.

This air purifier’s control panel adjusts the fan’s speed, sets a timer, and operates the unit’s night light. It also provides an alert when the filter requires replacement. Other touchscreen buttons include a child lock and an option to turn off all lighting.

Numerous and tiny circular holes perforate the front and back of this air purifier, feeding air to a three-stage filtration system. Then a fan forces the air through the filters and upward until it exits via the top of the device.

The minimum noise level is 21db, rising to 55db at the fan’s highest setting. At its maximum level, this device can clean 240 square meters of air within one hour.

This air purifier is fitted with a replaceable H13 HEPA Filter which incorporates an activated carbon element. A washable prefilter is also provided.

The Manufacturer

Kyvol is trademarked by Shenzhen VanTop Technology & Innovation Co., Ltd.


This Kyvol air purifier has a CADR (clean air delivery rate) of 240 cubed meters per hour. This figure denotes the amount of air that is cleaned of particles, sized 0.3 microns or larger, within one hour.

Kyvol has equipped this device with a relatively large filter. This is beneficial because a fan spinning at one specific rate can draw more air through a larger filter than a small one.

Due to its reasonably compact size, slightly oversized filter, and the ability to select one of four different speeds, this air purifier can be used in small, medium, and large rooms. However, if used in a large area, higher speed settings will typically be required, resulting in a greater noise level.


The Kyvol air filter is equipped with an H13 HEPA filter combined with an activated carbon element.

Most of the air purifiers I’ve previously reviewed have included HEPA filters wrapped in a fabric that trapped the larger particles sucked into the device. Kyvol has designed a prefilter consisting of two curved, fabric-covered frames. These prefilter elements slide snugly into the air purifier and fully enclose its HEPA filter. This is a superior design, resulting in a prefilter that lasts longer and can be more easily cleaned.

This air purifier is most suitable for small to medium-sized rooms but can be used in larger areas. Its filtration system captures up to 99.97% of airborne particles as small as 0.3 microns. The particles captured include dust, pollen, smoke, odor, and pet dander.

The main filter is not washable and should be replaced every three to six months.

Night Light

This device features an indent that circles the air purifier about five inches from the top. A ring light is fitted in this depression. This nightlight can be turned on as well a brightened using the unit’s control panel’s touchscreen.

The illumination is sufficient for me to identify and operate my home theatre remotes without interfering with the projected movie.

Timing Control

The Kyvol air purifier can be set to automatically turn off after one, four, six, or eight hours.

Noise Levels

This air purifier is equipped with four different speed settings. In the sleep mode, the fan revolves slowly, creating no detectable sound. When set to low, the fan noise is very faint. The noise is more noticeable but not particularly disturbing when the third setting is selected. Like all devices of this type, this air purifier becomes significantly louder when running at its highest speed. You would probably only use this setting in a large room or when trying to disperse an unpleasant odor.

If properly maintained, The Kyvol air purifier will last for many years. For best results, the filter should be replaced every three to six months. This device’s prefilter is washable and should never require replacement.

Overall Impression

It appears that Kyvol has worked hard to create a product that incorporates several improvements to the designs used by its competitors. These enhancements include a larger filter, a sturdy prefilter, and, most importantly, a greater selection of fan speeds.

The manufacturer has combined outstanding design work with excellent quality control. If you are searching for an air purifier suitable for a wide range of uses, the Kyvol air purifier would be your best choice.
