## 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
