Sand Filters vs. Cartridge Filters

Your pool filter plays a vital role in keeping your pool water clean and safe. While chlorine sanitises bacteria, the filter is responsible for removing those contaminants. Choosing the right filter can seem daunting, but with a little guidance, you’ll find the perfect fit for your pool.

Sand Media Filters:

Reliable and Efficient

Sand media filters work by cycling water through a canister of sand or glass media. As the water flows, debris particles are trapped, leaving the water clear and clean. They’re a popular choice for larger pools because they’re easy to maintain. Simply backwash the filter for 3–5 minutes to clean it. These filters are also time-efficient, making them ideal for busy pool owners.

Cartridge Filters:

Compact and Water-Saving

Cartridge filters are crafted from spun polyester and are particularly suited for smaller pools or spas. They save water as they don’t require backwashing and are easy to replace. Although they need more frequent maintenance, their compact design makes them perfect for smaller spaces.

Factors to Consider When Choosing a Filter

The right filter depends on several factors:

Pool Size: Larger pools might benefit from the durability of sand filters, while smaller pools work well with cartridge filters.
Maintenance: If you prefer low-maintenance options, sand filters may be better. For those focused on eco-friendliness, cartridge filters conserve water.
Space: Limited installation space? Go for the compact cartridge filter.
