Azeus True HEPA Air Purifier GL-FS32 | 4-Stage Filtration System, Ultra-Quiet Operation, and Air Quality Sensor | Ideal for Large Rooms, Bedrooms, and Offices by AZEUS

Absolutely the worst company that Amazon supports. There is no customer support, no way to contact them, no number, nothing. A waste of hundreds of dollars on these cheap, and easily breakable air filters that are designed to stop functioning after one year. The worst air filter on the market.

This air purifier is incredibly quiet when running! Setup is simple, just take the plastic off the HEPA filter, and plug in the AC power adapter. The AC power adapter uses a standard USB-C plug. The HEPA filter is black mesh on one side and white folded filter on the other, but if you gently shake it, you can hear filter beads moving inside of it, which I expect is the activated carbon filter. I really like the small handle that is formed into the back of the enclosure which allows you to pick up the lightweight unit with only one hand. I also really like the overview instructions that are printed on the back of the enclosure (since I won’t always have the instruction booklet nearby). There was a small piece of plastic inside the unit that seemed to be leftover from manufacturing (shown in photo). It was bouncing around the fan and making noise. I was able to shake the unit upside down and grab it through the vent, so it was an easy adjustment. The instructions state that the filter should be replaced every 6 to 8 months, and the filter type is available (and appears to be a standard type).

I am impressed with this small air purifier – it sits there quietly, minding its own business, until the quality of the air changes (I have mine set on auto), when it kicks into high gear. Once I found the button to turn off the display lights, it became even less intrusive. When the VOCs are absent, it is whisper quiet.

This little guy has lots of features, which are easy to set – you can ionize the air and/or turn on a UV light internally to kill bacteria. Our house AC already uses a UV light, so I have not enabled it on this air purifier, but I would do so if I were using this in a different location. Ionized air does not work well for me, so I have not tested it. The instruction manual does not elaborate on this feature, but ionization processes CAN produce ozone, and I could not find any information about the process used on this device. There is a light that changes from green to red if the VOCs are high – this function definitely works, as I can attest each time I use hairspray in my bathroom, this air purifier registers the increased VOCs in the bedroom.

For those of you who like to manually control matters, the Azeus purifier does not disappoint – you can pick the fan speed, choose from a variety of programs that automatically change the speed every 8 hours, and also set timers.

The filter boasts all the features one would expect nowadays – true HEPA and activated carbon. As an aside, the product page mentions a VOC absorber (which I thought was a function of the carbon filter anyway) and formaldehyde absorber. The diagram looks incorrect, as the black honey-comb filter is the activated carbon one, and it is located towards the inside of the machine; the prefilter is normally white and it is located towards the outside as the first barrier against the incoming air. The replacement filters, which are readily available on Amazon, do not include those two additional filters.
