Castle Filters MERV 8 HVAC Furnace Filter, 14x25x1, 1 Year Use

Introducing the Castle air filter, a revolutionary HVAC filter designed to last for up to a year. This innovative filter has the ability to capture as much dust as 20 regular pleated filters, providing high air-flow thanks to its open-cell, triple-layer core and tacky media for dust collection. In fact, it removes 93% of the most harmful airborne particles in your home (>5 microns). Treat yourself and your HVAC system to longer-lasting filtration with Castle Filters.

The patented Filter Technology used in Castle Filters involves 3 layers of ¼-inch open-celled foam, including a patented tacky center layer that catches dust like fly paper. Proudly made in the USA, Castle Filters has a US patent #10,183,249 B2.

Castle Filters' High-Flow MERV 8 air filter is designed to effectively remove 93% of the most harmful dust particles while still allowing maximum air-flow, offering superior protection for your equipment and home.

Our HVAC Filter boasts 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 allowing air to pass through.

With the Castle Air Filter, you can enjoy a filter that lasts for up to a year, holding up to 20 times more dust than a pleated filter. While pleated filters need to be replaced about once a month, the Castle Air Filter lasts for one year, making it 4-12 times longer-lasting than other filters.

By using Castle Air Filter, you can save energy with its advanced filtration technology, while also contributing to lower waste generation as it does not need to be changed every month like a standard filter.
