De-humidifier Recommendations

Hi there.... We have done a lot of research on controlling humidity in our Airstream (we have a 30ft International). As with a lot of topics, there are many opinions, and frankly, some of them appear contradictory. Still, I do learn much from everything I read.

Notwithstanding my reading, I would like to receive some input from our Airstream Forum friends on what works best.

I see we can use disposable systems, and there are some who use small, portable units, the efficacy of which seems to be all over the spectrum.

As always, we very much appreciate the wisdom our AS family can offer.

If I am camping with hookups, I run a small ceramic space heater and AC at the same time.

I bought a cheap portable unit with wheels and a 1.5 gallon reservoir from WalMart. It improved my comfort a lot in wet weather and could collect a gallon per day easily. I didn't worry about efficiency because it acted like a 700 Watt heater when it was working although the air leaving it wasn't very warm. It is a bit noisy but the dry air is worth the noise to me. I think you need a unit with a compressor to do a good job but maybe 2 or 3 of the solid state ones scattered around would work. I'd like to hear feedback from people who have used the solid state units.

At first it seemed odd that our owner's manual would devote so much attention to the problem of high humidity. But with all the attention they give it, their suggestion is to simply open a window.

When we got into weather that fogged our windows, just cracking the kitchen window was all it took to clear the air and make it comfortable. Sometimes the best solutions are the simplest.

This is what we use.

SPT SD-31E Dehumidifier with Energy Star, 30-Pint

It works well but is a little too big for our 30FB. We got it because it is a CR Best Buy.

I would suggest looking for a physically smaller unit that you can continuously drain into your sink.

Living in FL I consider myself to be versed in dealing with humidity. I have an Eva-Dry mini 500, a peltier with ionic filter dehumidifier and a Frigiaire FAD301 30 pint specifically for the trailer interior while in storage. During the summer I run the air when using the AS as it provides dehumidification.

The first two options are really a waste. They cannot provide the drying of the interior good enough. The peltier gets about a cup every two days and the Eva-Dry is overwhelmed in the 25'. It absorbs moisture but you would need several and they would require constant maintenance to recharge. The regular compressor type, the Fridigaire FAD 310, is powerful and drops my humidity to around 38-40% easily- dimensions (12.6 x 15.8 x 20.9). It is set to drain in the sink and every few weeks I go over and empty the gray tank water (note, only humidifier water). It heats up the interior dramatically but at least it is dry heat. The only other option I know of is a desiccant type. Eva Dry has a EDV4000. It uses 350-600 watts and can collect up to 1.84 gallons a day- dimensions (18"H x 11.5"W x 7"D). The Fridigaire model is rated to pull 2X the moisture from the air compared to the Eva-Dry. Both units at full power draw about the same wattage- 600 watts. Two advantages on the Eva-Dry are sized and that you have two fan speeds. Fan speed NOT an issue if you will not be present when operating as in the case of storage and, the newer Fridiaire 30 pint with digital readout has a fan speed control. I chose to save some money and buy the older rated reliable knob-only model. It is something to consider. Your best option is compressor type first, then dessicant. The others are not realistic options.

First post here. I have had great success with using Calcium Chloride to dry out interiors. I believe it's the same ingredient that damp rid is made of(minus perfumes). I buy a 50 lb bag for less than $20 and spread about a lb or two in a 20 liter Rubbermaid tote and watch the water collect. You will have to change daily if you are going in and out, but if I'm doing that, I'm running the ac. CC keeps the humidity a little lower than 50%

De-humidifier Recommendations

I cannot recommend this dehumidifier enough: EcoSeb DD122EA-SIMPLE Desiccant Dehumidifier, 15-Pint, White, 120V https://www.amazon.com/dp/B00KHJIC04..._beiyyb7V2R6FJ

Have one for our AS, one in our bathroom at home (doesn't have an exhaust fan) and bought one for my dad for use in his motor home. It's dehumidification capabilities are amazing, relatively small and quiet.

I second this recommendation. We were down in Charleston, SC the past 2 weeks and condensation was getting out of control. We primed one of these from Amazon for our 28' FC and after the first night our problems were solved. It is big enough to get the job done well but not so big as to be in the way.

I hope someone can suggest a system that drys the air and keeps the interior dry in winter storage where the average monthly high January to April is 50-65 degrees and average monthly lows are 35-40. Lots of humidity so I want to keep the inside dry without using electricity and without any other heat. I want to use the moisture absorbent and I cannot attend the system except 60-90 days so I am needing an overflow system into the shower and kitchen sink and into the grey tank. I can build stuff and I am cheap. I am not sure the calcium chloride will work but tell me more about that please.

Have you tried DampRid? It is available at WM and can last up to six months. Doesn't need a drain.

I am aware of damp rid. I have never tried it and since it is calcium chloride I am curious about setting up that system which will work in a situation where I cannot continually monitor. I need to be able to monitor every 80 days or so . So I'm hoping someone will Have suggestions. The part I don't understand is why water doesn't collect when using damp rid, which is calcium chloride

The DampRid absorbs the water vapour in the air and eventually it is all changed to liquid. The container that hold the DampRid is sufficient in size to hold the water. Of course after all of the DampRid is used up it is no longer effective. I have used this in my boat and found that it works quite well, but of course doesn't have a lot of water vapour absorbing capacity.

For continuous de-humidification you would need to have someone replace the expended DampRid or use an electrical dehumidifier with a drain (shower?) to your grey tank that has the grey dump valve open.
