Expert: David Deal Date: 5/27/2008 Subject: Basement Humidity/moisture
Question What's your opinion on the Humidex or EZ Breathe dehumidification systems to help reduce standard summer humidity levels in a basement?
I've always used a dehumidifier with just OK results & wonder if the "exhaust fan" technology works like the manufacturers claim. ( I could build the same system for very little money).
Thanks in advance.
Answer Well, here are some issues with those type sysems. Main issue is they can create negative pressure inside your basement and that can draw in radon and other spil gases. Also, that can create 'backdrafting' in gas appliances.
In most cases, systems like that should reduce odor and humidity but at what expense? Normally, I recommend normal dehumidifiers with drainage systems so you dont have to empty buckets. One should work, if not try two.
If you can build something, try it, if its cheap enough. Just check for gas appliance exhaust backdrafting and check your radon levels as well. If issues arise, do away with it.
Also, to help dehumidifiers work over larger areas, try using a ceiling fan or other air movement. That should move humid air into the devices range and dry air out into the room.
