Review: It’s not a HEATER - I’ve had my Air Dryer 500’s for over a year. We use them to keep humidity out of our RV 21 Feet long, and our boat to keep the interior from molding. These 500’s work great. Before using them my boat would have mildew on it every year, and we used Damp Rid in the RV. Now we just use these units. I see a lot of people writing reviews using these units as heaters. They ARE NOT HEATERS. If you want a heater, then buy a heater. Both units purchased were brand new and we have had no issues. Buy with confidence.
Review: This product is a MUST for all people with RV's! - We have had one of these for 5 years + in our RV and have now found a use for additional ones in our storage buildings. They are fantastic where there is fluctuating temperatures and humidity issues. We have told several people about this and have given some as gifts to our RV friends. It is inexpensive to run and no danger of being burnt when you touch it accidentally. Everyone who has an RV should consider this product as an essential item!

## Questions & Answers

**Q: Would this work in a small closet?  Hawaii dampness causes clothing and shoes to deteriorate.**
A: Yes, I think it would.  I have it in a safe about the size of an armoir and it drops the humidity by about 20% from ambient.  It raises the temperature about 10 degrees.  There is no guarantee, but in a small closet, I'd guess you'd see about a 10 to 15% drop in humidity and maybe a 5 degree increase in temperature.

**Q: After plugging this in for 2 hours, it does not feel warm at all. How do I know if it is working?**
A: You should definitely be able to feel warmth emanating from it. The unit should be warm. It is clearly  not working. Send it back! (But do exchange it - they work great)

**Q: We just purchase the davis instruments 1459 air-dryr 500 dryer, the instructions say to have air flow. what is the best way?**
A: We set ours on low pile carpet and it's fine.  I don't think it's critical--just a hard or semi-hard surface.  Works great to keep our boat from freezing.  We also use one in our guest house--just to keep the water from freezing and to prevent mildew.  But, we're in the Pacific Northwest and it doesn't get terribly cold here--seldom below 20 degrees.

**Q: Does this unit have a fan to blow the heat? Does it collect water somehow?**
A: No, it’s simply a mini (70 watt) heater. It works by raising the temperature slightly which lowers the relative humidity. I’ve got several and they do work as long as the space it’s used in is appropriately sized. This one would be good is an average sized closet.
