I'd like to know how introducing warm humid or rainy air affects this fans ability to dry a crawlspace. It seems it would counterproductive. Thoughts?

I agree, I have seen systems that have a computer and external sensor, to compare outside and crawl space humidity levels, to prevent the fan(s) from running if it is more humid outside.

I use mine in the cellar door to the outside and it keeps my cellar dry. Even when the springs outside squirt water in and I take on several inches of water the tjernlund underaire dries up the floor. MIKE

We have them set up to blow out. The purpose for us is to keep the air circulating to prevent mold growth in a crawl space.

There's no way to trap the humidity. When necessary I open doors and windows to ventilate, but often in the winter when it's cold and dry the warm humid air is welcome in my apartment. In the summer I don't really use the dryer much anyway. I have not had a problem with moisture but my apartment is larger and the dryer is in a relatively open area. If it is in a small, poorly ventilated space this may be an issue.

I am using in hobby greenhouse with high humidity. Don't see why vent a crawl space would be a problem

It's great during dry heat but it gets very humid. Not for cooling a whole room.

I don't know this fan is exhausting cabnetwork around a gas fireplace. No humidity involved in that situation.

In my experience, it dries within an hour. It helps to turn the fans on, too.

Not an answer, but a question...did you find a fan which is UL rated for wet locations? I'm looking for one that will be on our patio outdoors as well and can't seem to find anything here on Amazon.

The fan is not waterproof. So I would not do that unless you take it down for rainy days.

Too humid in LA for an evaporative cooler. You are better off with a fan. I lived in Canoga Park for a while...trust me when I say you DO NOT want to add moisture to the air.

The only emission noted is moisture (H2O) which has been a benefit: we used to suffer from excessive winter dryness. I added a small port to allow outside air enter the area near the heater because our home is very well sealed (normally this isn't necessary). The port can be closed; about 1 square inch. We do not need the fan on normally so the silent gentle heat provided is clean and quiet,and, keeps humidity at a comfortable level.

We found out that humidity is everything. On a dry day the output is so-so. On a humid day it is incredible! Regardless, it is a great little machine.

It really depends on the setting you put it on. This particular humidifier allows you to adjust the humidity level and it regulates itself to keep the rooms humidity consistent with the setting. We have out the humidity at 50% and the rug was damp. I suggest putting a towel in the direction the mist is blowing. Please don't let that deter you from purchasing this humidifier!! This is the only humidifier that we have found that works and works well!!! We absolutely love it!

It works just fine as long as the humidity is not too high. Much more comfortable than just a fan! I fill it with the hose when we use it on the patio, makes filling it up easy.

Just bought one. The fan does NOT run all the time. Fan always runs when compressor runs and sometimes runs when compressor is off. Fan shuts off soon after compressor does, but periodically runs so that humidity sensor can sample the room air. If air is too moist, the compressor kicks in. If not, fan turns back off. Sensible design.

The fan is powerful and should have no problem keeping the area cool, but keep in mind in high humidity it can get clogged after a month or so.

I run mine twice a day for 20 minutes and I can not tell that it actually adds any moisture into the room. I think it dissipates as fast as it emits into the air. Hope this helps you.

Thanx Don. That answers my similar concern. Many ductless mini splits run this way, short fan activity to sample air for dehumidification purposes, but it is nice to know that the fan will stay off if the humidity level stays controllled.
