Review: It worked great until it didn’t. Kitchen flooded. - I liked that it humidified the air and cooled down a portion of my great room allowing me to read in a very comfortable atmosphere.It is fairly noisy even at low level. Relatively inexpensive to buy and operate. I added a shut off at the hose inlet and used that to shut off the water overnight. Both pump and fan were turned off and the outside faucet was just barely open. The high pressure from the outside Faucet must have overcome the shut off at the water tank in the unit. Flooded the kitchen the water leaked into the ceiling below soaked through the drywall & dropped the gooey mess on my truck. in spite of all the smoke in the air I had to leave the house open for three days to dry out. I should’ve shut the water off at the outside Faucet & made sure that the pump was turned off so I didn’t end up running it with no water. The open water tank is a problem anytime the unit is moved it sloshes over. I am going to buy a portable air conditioner. No advice given on how to best use the unit. You are on your own to figure it out. Obviously I didn’t. Do not recommend.
Review: Perfect for porches, garages, mancaves - I can’t be happier with this purchase. Works great, especially on the hot days. We put it on our porch and it cools it 15 degrees. Works better than the portacool unit we have on the back porch, which is 3 times the price and this one bit does the same thing. Depending on humidity outside, water reservoir last 6 hours before needing filled.

## Questions & Answers

**Q: Would this unit cool an approx 150sqft garage enough for guests to sleep? North Florida climate is pretty hot!**
A: It will not work in Florida or any place with humidity. Need to have a dry climate for evaporative cooler to work.

**Q: Removable filterpads? Can they be cleaned or do you purchase new ones**
A: From what I read they can they are removable, cleaned with the special agent and replaceable

**Q: Is there a safety to turn the water pump off if the water gets too low?**
A: No. There is not a safety shut off for the water pump should it run dry.  I keep mine hooked to water hose so this never happens

**Q: Can I attach a hose to it?**
A: Yes
