Over time minerals can build up in your evaporative cooler. They can accumulate from places where hard water has come into contact like the tank and water line. Unfortunately, these deposits can be harmful to your unit causing corrosion and malfunction in some of the components. That means your Port-A-Cool swamp cooler can't operate at optimal efficiency but it can also actually decrease the life of the unit.

Ensure that your evaporative cooler is cooling as effectively as possible with the MK-47 mineral treatment additive. It works with all Port-A-Cool models. It's very easy to use and will pay for itself since it will extend the life of your cooler.
