Dial 3078 DuraCool Cooler Pad, 29" x 144"

These work well. I have to cut them to size but it saves me money buying them in the roll.

I removed the aspen and put in two layers of this and it seems I am getting about 5 degrees cooler air from my swamper. It seems to keep my home 3 or 4 degrees cooler. This makes a huge difference in the high desert climate of Reno Nevada. I particularly like how clean it is and how easy it is to work with. Also, it's uniformity assures that all air is being humidified uniformly, whereas with aspen, there were often concentrations and gaps in the coverage. Air flow through two layers is probably a little less than with aspen, which means a little higher temp difference between discharge temp and room temp. It also means the fan runs a little quieter, which is appreciated.

This is great stuff. Not sure how it will compare to the grass pads that came with my swamp cooler, but you sure get a lot of this in their big roll of padding for the price!My only complaint (?) is that these pads are VERY THIN, compared to the grass mat pads. I'm thinking the water will just zip right thru them quickly, and there won't be much evaporation to provide cool air.Also, being thin, they don't hold well in the frame, and tend to slip down, despite the steel 'pokey' things that are supposed to hold them up. We'll see how they perform next summer. Right now, I have not run the cooler with these new pads installed (because its 39 degrees here in Las Vegas!).I may try to double up the pads to make them thicker if they don't cool as well as the grass mat pads.

Easy to cut to size & install, noticeable improvement over aspen pads. Would buy again for sure.

The mats are smashed and do not work as intended.
