Perfect fit for my unit!
Just needed one piece of styrofoam on the side to snug it up. Perfect fit on top. Never had an evap cooler that used these pads until now. These things cool the air down maybe 15 or 20 degrees when it’s in the mid 80s easy. Would buy again for sure!

a good first season using it!
it comes in two parts that fit side by side in your swamp cooler. the directions were not thorough to me, but i watched another review which instructed me on which direction to install them. if installed backwards, the air flow is not good and thus, won’t cool off effectively. they stamped directional arrows on the sides, but it was somewhat faded and hard to read. once installed, they worked well. i did not smell a weird odor when first installed and the swamper turned on….as others smelled. overall i’m satisfied!

Finding the correct pads
Our original pads were 3 large and 1 smaller had these pads for 6 years. When we received only 2 pads I got worried but these 2 pads fit our unit perfect! Second concern was regarding the smell. Yes it did stink for about 5 hours running it, expected to sleep in our Rv but by shutting down the unit for the night it was ok the next night.

Just what I needed
I really needed these pads for my cooler. They are exactly the right size and the price was good. The package actually arrive ahead of schedule.

Cools well, stopped spitting water onto my roof
It is a little stinky at first.I thoroughly cleaned my unit, and installed this new pad. It initially smelled terrible. I thought it would last a week-ish, but that was when I could no longer tolerate the smell. I finally gave in and changed the water and put in 4-5 drops of tea tree oil in which removed the smell completely. The directions said that this does occur for a bit.Putting this in got rid of the the mildew smell that had been slowly increasing. It is probably about as efficient as the old media pad due to the tea tree oil being added. The biggest benefit was that my old pad was staining my roof near the cooler. It no longer drips onto the roof when running.
