Replacement filters for inflatable pools are essential accessories for owners of Bestway VII / Intex D inflatable pools. These polyester fiber filters are resistant to high temperatures and strong acids, providing efficient filtration by removing hair, leaves, dust, sediment, and sand from your pool. They are strong and durable, resistant to high pressure and corrosion. By extending the lifespan of your equipment, these filters allow you to save money. Each set includes 6 reusable filter cartridges, which can be easily cleaned with water after use. We recommend changing your inflatable pool filter every 4 to 6 weeks for optimal performance.
