【Premium Materials】Approximately 108 x 73 mm (L x W), suitable for Intex S1 filters. The cotton filter cartridge is made of high-quality sponge. Our filter sponges are compatible with Intex S1 filters and most pool filters on the market, keeping your pool, aquarium, and spa clean. 【Cost Savings】Regularly replacing paper filter cartridges is part of routine pool maintenance, leading to higher costs and waste. Our reusable, washable filter sponges are the ideal alternative to disposable filter paper. You don't need to replace filter sponges frequently. 【Keep Water Clean and Fresh】This sponge can be directly placed over the filter inlet to effectively absorb particulate matter and sediment, improving biological filtration efficiency. It has good elasticity, strong tensile strength, fast dust removal, and a high filtration rate: with this filter, you can enjoy a safe and healthy massage spa experience. 【Friendly Reminder】These washable, reusable sponge filters can reduce your costs. For better filtration and to keep your pool clean, we recommend replacing them every one to two weeks.
