This pad absorbs moisture from the air? What about our 7% relative humidity in Arizona? We don't have any moisture in the air.

The problem here is that Amazon did not describe what pad you are talking about. PLease define so I can properly answer your question.

The vinyl, high-heating pad is tucked into a washable, fleece sleeve providing a comfortable, absorbent buffer for the moisture on your skin, that the heat may generate (perspiration).

Never had a problem with this pad in ARIZONA. Everyone should have one of these

Hi, that is exactly what we wanted it for and it works great, couldn't do without it now. No, no humidity added that we've noticed. We live in Central Vally California and with the heat in summer there is no way my husband could work out there. A Port-a-Cool is a must have for us!! Hope this helped.

The temperature is less of an issue than the moisture. It is not rated for outside use.

The air is fine. Ours hasn't been covered since it got opened, and it hasn't dried out (and we're in the desert). Not sure about the water though.

I haven't tried it.....not sure what the moisture would do to it. Sorry couldn't help.

Yes. I have been using it on a daily basis at the gym as well as running.It does not accumulate any moisture.

Humidity is rated not in degrees of any kind, but as a percentage. It is the same all over the world.

I have not had any moisture problems with the compilot, but have not used it really moist places.

We have wood floors, but have never noticed any moisture on the floor. The vents are on the side and go straight out .

I do not use the pads, they are optional, and I feel no heat coming from the unit near where the pads would go. No real heat at all coming from it, just the mist and a small "white" noise of it running.

Not breathable, it does hold moisture underneath. I can use it as I have concrete patio.

It doesn't let moisture make its way down to the the mattress.The mattress pad its self will get get wet in its top layer of material but it is waterproof. It is also not crinkly or noisy like cheap or old versions of waterproof mattress pads. When i took it out of wash a couple days ago i actually noticed how well it is holding up.

It will work better in high humidity. You get a better seal by wetting the pads.

I was not able to notice if it was a good insulator as the time of year was not very cold. I also have a -10 degree bag so it really did not allow for the pad to do its job. I would have to say that it would make a good insulator though as the main source of cushion is air, and it holds it well.

The amount of water it absorbs depends on the relative humidity surrounding it and also how long you leave it exposed. The "equilibrium moisture content" of silica gel at 90% humidity is about 35% by weight, and this product has 750 grams of silica gel, so about 260 grams of water at that relative humidity. However, at 50% relative humidity, this "EMC factor" is only about 25% and therefore can only hold about 180 grams of moisture. I have tested these indoors and outdoors in Oregon (50% and 90% relative humidities, more or less) and these numbers are roughly right. It took about 2 weeks for it to fully saturate in 90% relative humidity and probably twice that in 50% relative humidity. The rate of water adsorption slows down as it gets close to saturation. Note that at 100% relative humidity the amount of water vapor in a volume of 1000 cubic feet depends almost entirely on the temperature and is about 13 ounces at 50 degree Fahrenheit and 47 ounces at 90 degrees Fahrenheit. At 50% relative humidity, the water content would be half of that. It is probably better to look at devices like this as "moisture buffers" instead of "moisture adsorbers." If the silica gel is saturated at 90% relative humidity and you put it in a drier environment, say 50% relative humidity, it will actually release some of the trapped moisture until it reaches equilibrium again. Probably more than you wanted to know about this, but I have been studying it to see if I can find a solution for my boat while it is in storage, and I'd like to find something that doesn't need "recharging" every 2-6 weeks. By the way, it is NOT effective to "recharge" these in a gas oven because the combustion releases water vapor, making it difficult to ever get the silica gel really dry. I ended up buying an electric toaster oven to solve this problem. (Makes better toast, too!)

if you need a very absorbant pad, i find they do not have great absorbancy. they are thin. but for the purpose i use them for they are sufficient.

Mine doesn't seem to trap any moisture. I don't live in a super humid area, but we have his lots of rain an the TV seems to be bone dry in its cover.
