Equate 1.1-Gallon Invisible Cool Mist Humidifier

this unit has a fan. so it makes a noise compared to other humidifier. I can't see the cool mist coming out of unit but it pushes just as much water into the air as other humidifier. what I like the most is the secure handle on the water tank. I have had it running all day for about 3 weeks and I can already see a discoloration in the filter. they state to change filter every 1-3 months depending on use. if you buy a 4 pack on Amazon the filters will cost $5 per month at maximum use. unit is big 2 times the size of other humidifier.

It makes noises that even scares my cats, it's not quite at all, the filter I don't like because you have to soak in cold water and it seems like it would be a hazard because it has metal in the filter and looks like it rusted in the first use,you cannot see the mist so I don't know if it works and yes I know it's invisible but cannot tell the difference definitely doesn't work for me but everyone is different so up to you plus you cannot put the water tower in the dishwasher you have to clean by hand and it's not that easy to clean so not for me.
