    Replaced my pads on my cooler with these MasterCool replacement pads. The pads work fine but there is a very bad odor in the air. Been running them for 3 days now and still just as bad as it was. After looking on line I saw many others complaining about the same problem with the MasterCool brand pads. MasterCool say to rinse the pads with water and then empty and, wash out the cooler pan (which is on the roof and already been done before installing pads) and run for several hours and the odor should go away. Well 3 days later the order has not gone away. I have replaced my pads many times over the last 18 years and never had an odor problem until now.
    Get with it MasterCool….

    I replaced with a Pad set from , item 564453 a couple years ago. Had no odor problem then. About to get another set today. Will add some Downy fabric softener and run it until automatic purge occurs. Regarding mold in Albuquerque, I would try colloidal silver (liquid) because it has no odor of its own, it kills fungi and bacteria, and the nano 20ppm pint version is cheap.

    Saw the reviews and looked for an alternative. Since it’s end of summer, no luck. Ordered and installed them. That was the end of September. The air coming in still smells like a chemical plant. I’ve hosed down the medium pads, sprayed lavender oil on them, and run them 24/7 for days. Still stinks. Can’t imagine this is healthy. Not pleased and really looking for a substitute.

  4. DV

    I have replaced the pads three times since 2013. Each time, mold develops after just a couple months use although I live in a desert climate here in Albuquerque, NM. I ‘m still trying to contact the manufacturer to inquire about the warranty but it appears they keep a very low profile. There must be a way to treat the pads to inhibit mold growth without compromising indoor air quality to justify a five year warranty..

    easy to install, was the right size. nice it comes with hardware, no instruction but if you can think you can do it

  8. Mel

    Package came in 2 days and contained everything to replace old pads. The old pads were 6 years old.

  9. zanado

    too expensive to use in West Texas where we have high winds. Feathers, leaves & dirt are blown into filter holes & clogs the filter making it useless.

    Outstanding product, easy to install, my shop is cool again, I replace these every 3 years on my MasterCool evaporative cooler.
