I suggest installing a blast gate at the back of your machine. I live in a very humid climate but have never had moisture in my machine. A blast gate beats unhooking the hose every single time and then reconnecting it to use the laser again. If you search for blast gate on the community (Search results for 'blast gate' - Glowforge Owners Forum) you will find several you can make yourself as well as some purchased ones. I made mine out of acrylic based on this design: Glowforge mounted blast gate.
