Questions and Answers for Air Innovations 1.6 Gal. Cool Mist Digital Humidifier for Large Rooms Up To 500 sq. ft.

A:  See my review. You have to carry the tank to your sink, turn it upside down to fill it. Kind of inconvenient, but workable. Holds a lot of water.

A:  Pull out the smoke-colored tank, flip it over and unscrew the filter on the bottom. Then fill it using the kitchen sink or bath tub spout as the tank is too tall to fit anywhere else. This isn't as hard as with other humidifiers because there are handles integrated into the top and bottom to make it easier to hold.

A:  No, you remove the top tank and flip it over. The inlet is on the bottom of the tank. But the top is flat so it can sit as you fill it.

A:  You fill the unit by removing the see through tank, turning it upside down, removing the filter by a couple of turns. Fill the unit, secure the filter back in place and turn the tank right side up and place it back on the base. Very simple to use.

A:  Fill it from the bottom of the tank by taking out the filter.

A:  No, be careful and follow the complicated instructions which you may have to read several times.

A:  No, the tank is removable - this one has a flip up handle - and is filled from the bottom of the tank by unscrewing the filter. I think this design is pretty typical, all the humidifiers I've owned have been designed this way.

A:  take the top off, turn upside down, unscrew the fill cap(which has the filter attached) fill with water and put back on unit. Not that hard--
