Expandable Aluminum Gutter Filter

Each filter measures 15 x 8.0 cm (approx. 3-inch width when expanded) and is made from rust-resistant, waterproof, weather-resistant aluminum. Weighing only a few grams per unit, the lightweight yet heavy-duty construction ensures secure fit and long-term outdoor durability. The adjustable, tool-free design allows easy compression or expansion to fit most standard downspouts — simply push into place. Ideal for UK homes with seasonal leaf fall, these filters act as a physical barrier at the downspout entrance to intercept leaves, twigs, moss, fine dirt, and airborne debris before they enter the pipe system. Regular use reduces internal pipe clogging, lowers maintenance frequency, and helps prevent overflow-related dampness or foundation water pooling.
