Great Price. They are not exactly the same as the originals but I believe they are even better.

### ⭐⭐⭐⭐ a good first season using it!
*by R***L on September 29, 2024*

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!
