Setting up the air purifier was very easy. Make sure you get non iodized salt! The system is very easy to use, being able to switch between 3 speeds. Continuous use lasts about 2-3 days then you have to refill the water and salt. That gets pretty annoying but it is what it is. I wish there was a light indicator when the air isn’t clean, and another when the air is clean. Such as if smoke is detected or dust, etc. in case you wanted it to alert you to turn it on if you don’t run it all the time. I had to put it on the lowest speed because it gave off a watery smell, like a pool. I keep a humidity reader in the room also just to make sure it doesn’t increase the humidity and so far it has been fine. The unit isn’t super mini, but it’s also not a terrible eyesore. I keep it on my nightstand or desk. Overall I am pleased!
