Castle Filters MERV 8 HVAC Furnace Filter 14x20x1 - 1 Year Supply

Introducing the innovative Castle air filter, a revolutionary HVAC filter designed to last for up to a year. This cutting-edge filter boasts the ability to collect as much dust as 20 regular pleated filters. With a high air-flow and an open-cell, triple-layer core featuring a tacky media for dust collection, it removes an impressive 93% of the most harmful airborne particles in your home (>5 microns). Treat yourself and your HVAC system to longer-lasting filtration with this game-changing filter.

Patented Filter Technology: Castle Filters utilize 3 layers of ¼-inch open-celled foam, including a patented tacky center layer that efficiently captures dust particles, much like fly paper. Proudly made in the USA, it holds a US patent #10,183,249 B2.

MERV 8: The High-Flow MERV 8 air filter is highly effective at removing 93% of the most harmful dust particles, providing superior protection for both your equipment and home while allowing maximum air-flow.

HVAC Filter: Castle Filters offer an impressive 400% more surface area for dust and other particles to collect. The internal foam is treated with a sticky material to attract more dust while still allowing air to pass through.

Lasts One Year: This furnace filter has the capacity to hold up to 20 times more dust than a pleated filter. While pleated filters typically require monthly replacement, the Castle Air Filter lasts a full year, which is 4-12 times longer than standard filters.

Save Energy and Lower Landfill Contribution: The Castle Air Filter not only helps you save energy with its advanced filtration technology, but it also contributes to generating less waste, as it does not need to be replaced every month like standard filters.
