Watkins Filter Cartridge, Tri-X Ceramic, OEM Replacement Filter, Set of 3

About $200 cheaper than the manufacturer, and the exact same product. Arrived in goid condition, packed well, and fast shipping. My husband put our old ones in the washing machine,mif you can believe that. It shredded them. There are probably still pieces of those things in his man cave washer. Lol. These fit perfectly in our Hot Springs hot tub. Way cheaper, and way less hassle than having to deal with the paper filters. These are solid, made from a ceramic-type resin of some sort. They will last for years and years, and according to the manufacturer, can be washed in the dishwasher. Not the washing machine. What we have done in the past is soak them in a 5 gallon bucket with muriatic acid. Worked great.

When we bought our Hot Springs spa the dealer gave us three ceramic filters and they work MUCH better than standard paper filters because they filter out so much smaller particles and last longer between cleanings. I bought these to replace the original filters which are maybe 4 years old. Exact fit. I'll buy again.

Best way to clean these is to get a plastic milk carton from your grocery store, place the filter on a broom stick inside the milk carton and hit it with a hose. You can really get it spinning and can watch the color change as the debris get washed and flung off the filter.

These are the best filters I've found for my HT. Maintaining them properly (monthly rinse/clean) they have lasted me about 3.5 years in a saltwater system.

Fits our hot spring spa.

I am super picky.. Quality & Durability is what I look for. If I give some thing 5 Stars it must be pretty awesome.

VERY easy to clean!

Much better than the pleated ones.
