Reusable filter sponge for swimming pools and spas – S1 washable foam cartridge, high filtration capacity

【Cost Reduction】Summer is coming, and replacing paper filters is part of daily pool maintenance. Using disposable filter paper and poor-quality filter cotton will increase monthly expenses and become a headache. Compared to other filter cottons, our filter cotton is made from high-density sponge material that won't easily be damaged or dissolve, so you don't need to replace it frequently. 【Durable Material】The filter foam is made of high-quality sponge, offering high elasticity, sufficient thickness, moderate density, softness, and resistance to deformation. It is also environmentally friendly, reusable, and has a long lifespan, making it ideal for S1 type filters. 【Super Filtration Function】 The foam filter element has a high-density mesh structure, which can effectively remove 90% of leaves, weeds, hair, insects, and other floating debris from the pool, keeping the water clean and reducing bacteria, eliminating user concerns about water quality and safety. 【Strong Compatibility】 Our foam pool filter is inexpensive and long-lasting, can be cleaned and reused multiple times, and measures 11*7 cm. It is suitable for S1 type and most pool filters on the market, keeping pools, aquariums, and spas clean. 【Easy to Install】 The foam filter element requires no tools and is easy to install. It can maintain clean water quality for a long time, ensuring a wonderful summer. Note: The packaging is vacuum compressed.
