As swimming season approaches, now is the perfect time for homeowners to check their pool filters. Proper filter maintenance not only keeps water crystal clear but also helps protect expensive pool equipment and reduce long-term costs. Routine inspections and timely service help prevent these issues while keeping pools healthier and more enjoyable for families and guests.
DE Filters: Annual Cleaning Keeps Them Performing Best
DE (diatomaceous earth) filters provide excellent filtration, but routine backwashing alone cannot remove all buildup. Over time, oils, minerals, debris, and residual DE powder accumulate inside the filter grids, restricting water flow and reducing efficiency. Manufacturers recommend a yearly breakdown and deep cleaning to restore proper circulation, improve water clarity, and reduce strain on pumps and equipment. Its also a great opportunity to inspect grid condition. This preventative service helps ensure your pool stays healthy throughout the swim season.
Cartridge Filters: Replacement Is Part of Normal Care
Cartridge filters gradually wear down as the fabric media ages. Even with regular cleaning, cartridges can lose effectiveness and restrict water flow. Most pools require cartridge replacement every 18–24 months, or sooner if signs of wear such as fraying, cracking, flattening, or declining performance appear. Using higher-quality cartridges often provides better durability, improved filtration, and longer lifespan, making them a smart investment for homeowners seeking consistent water clarity and fewer maintenance headaches.
Sand Filters: Don’t Forget the Media Inside
Sand filters are known for their simplicity, but the sand itself slowly breaks down and becomes compacted, reducing its ability to capture debris. Manufacturers typically recommend replacing sand every five years to maintain proper filtration. Homeowners may also consider upgrading to glass media for improved performance and longevity, or converting to cartridge or DE filtration for enhanced water clarity.
