YOU HAVE COME TO THE RIGHT PLACE!

100% GUARDIAN GENUINE REPLACEMENT FILTER CARTRIDGES.

GUARDIAN is a brand created with you in mind - manufacturing proven, quality products that are affordable for pool and spa owners.

Based in Northwest Pennsylvania since 2003, we began with a simple goal - manufacture high-quality pool & spa filter cartridges that don't cost an arm and a leg. We've maintained that goal for over 15 years, making and warehousing replacements parts for over 200 of the most popular cartridges. Our customers return because they know our products are made from the best materials and provide high performance filtration providing peace of mind that your water is crystal clear and clean.

We GUARANTEE our products with an easy 30 Day return policy and fast delivery.

Here at Guardian you can be assured that every filter comes direct from our production facility and are compatible replacements for UNICEL, PLEATCO, FILBUR and other brands.

We urge you, beware of cheap online imitations!

We know there are a lot of cheap imitation products at lower prices on the internet that pretend to be Guardian replacements, but honestly those products use cheap materials, do not provide proper filtration and have a very short lifespan costing you more time, stress and money!

Thanks for choosing Guardian. We won't let you down!
