How Do I Take Care Of My Hot Tub Filters?

May 2015
Your hot tub filters are absolutely essential to maintaining clean water and ensuring proper performance of your hot tub. Dirty, clogged or worn-out filters will fail to trap contaminants and put a strain on your spa’s jet pumps. 
 
Your genuine Watkins® filters are designed to last 2 to 3 years. Here’s how to take care of them. 
 

Monthly


Once a month, it’s a good idea to remove your filters and spray them with a garden hose to remove any debris that may have accumulated between the folds. 


Three To Four Months


Whenever you change out the water in your hot tub, give your filters a full cleaning. Remove them from the spa and spray away any debris that has accumulated between the folds with a garden hose. 
 
Soak the filters over night in a spa filter degreaser (see package instructions for the product you’re using). After soaking the filters, spray them clean and replace. 
 
Do not use a pressure washer or dishwasher to clean your filters. 
 
Tip: You can avoid any spa down time by owning two sets of filters. Simply switch the filters to be cleaned with your other set. Then clean and store the set you’ve removed.


Two To Three Years


If you’ve maintained your cleaning schedule, your genuine Watkins filters should last up to 3 years. You may want to replace them sooner if maintenance has been sporadic or your hot tub has seen heavier than normal use. 
 
Replace your filters sooner if the filter is brown, gray or green, or if it stays dark yellow after cleaning. You should also replace filters if you notice that the pleated part becomes flat or the fiber begins to shred or fall apart. Also replace if the top or bottom of the canister has a split or crack. 
 
When it’s time to replace your filters, check with your local Caldera Spas dealer for the Watkins filters specifically designed for your spa model.
