Inadequate Amazon description
Good product but the advertisement is misleading. The video posted does not apply to this model. You will not have any indicator of the filter performance….

I bought this for my daughter's room as she was waking up with puffy eyes with dust allergies. This little device does make a big difference if used properly.

Liten och väldigt tyst. Har den i ett ganska litet sovrum. Tycker den verkar bra.

The whole reason I purchased this item was because I was looking for a battery powered device. The description and specifications say it is battery powered, but what I got was one that required to be plugged in.

Hab es für meinen 3d drucker gekauft, damit filament was erhitzt wird gefiltert wird. Also ich hab PETG filament gedruckt, und es hat bei mir komplett den Geruch gefiltert
