Dial 3438 Mastercool Cooler Pad, 40" x 28" x 8"

Great price. Everything fit great. Terrible smell for the first several days, but going great now!

For the dry desert southwest, evaporative coolers, also called swamp coolers, are a simple and ingenious device for cooling your house. They are nothing more than a big box containing a fan and a water soaked pad. As hot dry air is drawn across the wet pad and into your house, evaporation causes rapid cooling of the air and it feels just as cold as air-conditioning, for a fraction of the cost. During the six weeks or so of late summer monsoon weather, the air becomes humid and the swamp cooler is useless. But for the rest of the hot season you will save hundreds of dollars off your cooling bill. In my area, the water is supplied by the Colorado River and deep wells. It's full of calcium and other minerals. The 8 inch thick cooler pads go in looking and weighing like corrugated cardboard, but after 3 to 5 years of use, they come out looking and feeling like concrete from all the minerals deposited on them by the evaporating water. At this point they need to be changed out. This is the third time I've had to change the pads in my coolers. This is also the third brand of cooler pads I have used and they ALL have the same slight odor for a few hours when new and first soaked with water. Smells to me like library glue from my school days. It's not all that bad and it's certainly not toxic. I suspect that the two users who gave such low ratings to these pads have never changed pads before. They'll just have to get over it, or of course there's always the option of using your air-conditioning instead, if it bothers you that much! These pads are just fine, no better and no worse than the pads I've used before. They do their job. Amazon also sells them at a better price then the local stores here in town!

Pads fit perfectly and work great just has a funny smell but I knew that was going to happen.great product.

The filters work and fit nicely.

I almost passed on ordering these, but I'm glad that I didn't, they are just what I needed. Plus they weigh more then just 1lb. what you get is two pieces no a single pad, each pad is 20" W x 23" H x 8" D. They are of good quality, And very fast delivery. It would have cost me $30.00 more if I had gone to local store.

These pads were a perfect fit for my unit. Quality is a little lightweight. I dropped 2 stars because of the 3rd party supplier. WARNING: This order was not a problem but a later purchase from them ended in a nightmare. Very expensive item was missing parts. Supplier accepted return but dinged me over a hundred dollars for restocking fee. Not only that, I had to pay return shipping charge which was over a hundred dollars. Amazon made it right and paid me for both issues. I can not recommend this supplier.

I am very pleased with this product. The odor reported by many reviewers was not a problem for me. The instructions suggested running the pump only for 24 hours and flushing the water from the cooler after this process. Yes, there was some odor for a day on so, but it was not objectionable. I flushed the water again and the odor was gone after a couple of days. My old pads did not look that bad, but the new pads absorbed water much better and cooled better. I highly recommend.

Exactly what we needed. No complaints. Packed well, good quality. Worth every penny.
