I have this air purifier in the room I spend the most time in during the day, my office. The Aria Mini is a simple, effective, easy-to-use air purifier that makes my office feel fresh and clean. Just add the non-ionized salt and water, follow the controls and you are off. The controls are straightforward. I was skpetical at first that this little machine would do much but after leaving my office mid-day and coming back later with it still running, I slipped back into my fresh air office. And if it is killing airborne germs and viruses, that's great too. I just noitce the improvement in the auality of my room's air and for that alone it is worth it to me.
