The Swell Pressure Filter Deluxe is our range of powerful pressurised pond filters, designed to maintain healthy water in ponds. These pressure filters use powerful UV lighting and multiple layers of filter media to remove algae, waste and chemical impurities. Suitable for a wide range of setups, these filters can be used in garden streams, fountains, waterfalls and more. The pressurised filters are designed to be continuously run by a pond pump to ensure clean and clear water all year round. Pressure filters, unlike traditional pond filters, use high-pressure filtration combined with multiple layers of filter media and UV lighting to process a large volume of water in a small space, unlike traditional box filters which often need to be as large as a bathtub. Pressure filters can also be cleaned from the top down, so the unit can be buried up to its head in the ground, keeping it out of sight. Finally, pressure filters are very easy to maintain, making them suitable for quick home repairs to keep them performing at their best for years after their warranty period.
