Replacement Cartridges

Which replacement cartridge(s) do you need?

As a Lakota customer, you will receive a reminder card once per year when it is time for you to replace your filter cartridge. Because not all filter elements are replaced at once, it is best to call or e-mail for instructions on which filter(s) you need. 

We encourage you to call as we are continually adding new types of media to our inventory and can advise how you may benefit from these improvements.

With over ten different media and  filter types, we can adapt to your special filtration needs.

Call 800-945-5782 or 651-645-1004.
