Introducing the Castle air filter, a revolutionary HVAC filter designed to last up to a year. This innovative filter boasts the capability to capture as much dust as 20 regular pleated filters, providing superior performance and longer-lasting filtration for your home.

Featuring a high air-flow design, the Castle air filter is equipped with an open-cell, triple-layer core with a tacky media that effectively removes 93% of the most harmful airborne particles (>5 microns) in your home. With patented filter technology utilizing 3 layers of ¼-inch open-celled foam, including a patented tacky center layer that catches dust like fly paper, Castle Filters are proudly made in the USA with US patent #10,183,249 B2.

Ranked as a MERV 8 filter, the High-Flow MERV 8 air filter effectively removes 93% of the most harmful dust particles while still allowing maximum air-flow, offering superior protection for your equipment and home.

Castle Filters are designed specifically for HVAC systems with 400% more surface area for dust and other particles to collect. The internal foam is treated with a sticky material to collect more dust while still allowing air to pass through.

Unlike pleated filters that need to be replaced about once a month, the Castle Air Filter lasts up to one year, holding up to 20 times more dust. This means the Castle filter lasts 4-12 times longer than standard filters, providing convenience and cost savings.

In addition to providing superior filtration and lasting longer, the Castle Air Filter also helps save energy with its advanced filtration technology, contributing to lower energy consumption. Moreover, it also reduces waste by eliminating the need for monthly replacements, helping to lower landfill contribution.
