4-Pack of Filbur FC-3741 hot tub spa filters is compatible with C-6617 PC17 spa filter models. This hot tub filter by Filbur comes in this money-saving bulk 4-pack and is made with strong, reinforced cores, antimicrobial end caps and high quality polyester filter media to ensure clear, clean water along with highly efficient filter performance. Most spa manufacturers recommend rinsing off the filter regularly and replacing it annually. It is best to have at least 2 filters on hand so that when one is being cleaned, the other one can be used in the spa. This also allows for an overnight filter soak on a filter while the other one is performing filtration duty inside the spa. Some spas also use more than one filter at a time.
