Description

The Clean Air Optima CA-503B Compact Smart filter kills bacteria, viruses, and fungi. This is because the air purifier has a UV-C lamp, which kills harmful bacteria, viruses, and fungi. With the HEPA 13 filter, it removes dust, allergens, and other particles from the air. The ionizer lowers floating particles to the floor. The air purifier has a sensor that measures the air quality and it automatically adjusts its operation if it senses pollution. You can connect the air purifier to the smartphone app to control it remotely and to gain insight in the air quality. It cleans the air in rooms of up to 28m2. Thanks to the extra silent night mode, you can also use it in your bedroom.

Very satisfied with it.

Filters TVOC and VOC
Can be controlled from phone
Automatic speed

I have several 3D printers and was looking for an air purifier that filters TVOCs and VOCs in addition to the "normal" ones. 3D printing can release unpleasant odors, especially with technical filaments, as well as other harmful fumes.

It's especially nice that you can control the purifier with your phone.

The automatic mode also works as expected.

Disappointment regarding unpleasant odors

Easy to operate
Has little or no effect on unpleasant odors

Unfortunately, I'm disappointed with the air purifier. I bought it to eliminate unpleasant odors in my house, but I hardly notice any difference when it's running. I don't have allergies, so I have no idea if it has any positive effects on them.
