Review (1/5): Thought this would be GREAT...turned out, didn't work
I was really excited to get these (ordered 2) because of 1) the automatic off feature 2) larger water capacity 3) price was great! I guess the old saying "you get what you pay for" applies here. We live in a very DRY climate so I got these to help add moisture and fragrance to the air in our home. When I bought them they were titled "diffusers" but it looks like now the seller has changed the picture to a different product with the description "Air Purifier Air Cleaner with HEPA Filter, portable for home office car"??? This item definitely DID NOT come with a filter and plugs into a standard outlet so I'm not sure how it would be "portable" or work in a car since you would have no way of plugging it in. That being said, when these first came they were great! Only down side was that there is a "high/low" button for output but no instructions on how to set it other than push the button...so, when is it on high? when is it on low? no way to know unless you just keep pushing the button and see what happens. Even then, there was really no difference in the output. Initially I thought these worked well but then noticed that they weren't putting out much of anything at all. I tried changing the high/low setting and still nothing. It seems like the opening isn't right so none of the "mist" comes out and all of the water just kept recirculating around inside the machine. Since these have an auto-off feature when the water runs out/low they never ended up turning off, since the water never left the chamber, causing them to get extremely hot. Viewing this as a fire hazard and not getting anything worthwhile out of them I was happy I was still within the time frame to return them. Guess I will be looking for a better option and maybe trying an actual humidifier.
