Pool Filters

Choosing the right pool filter is essential for keeping your pool water clean and safe. There are three main types: sand filters, cartridge filters, and diatomaceous earth (D.E.) filters. Sand filters are affordable and durable, using sand to trap debris but requiring regular backwashing, making them suitable for larger pools. Cartridge filters are more efficient, capturing smaller particles and needing less maintenance, ideal for residential pools. D.E. filters offer the best filtration by trapping the finest particles, but they require more upkeep and are typically more expensive, making them perfect for those seeking top-tier water quality. The choice depends on your pool size, maintenance preferences, and desired level of filtration.
