One-Year HVAC Furnace Filter, MERV 6, 16x25x1, 1 Count

Introducing the Castle air filter, a revolutionary HVAC air filter designed to last for up to a year. Compared to 20 regular pleated filters, this new filter has the ability to collect as much dust. The open-cell, triple-layer core of the filter, enhanced with a tacky media, ensures super air-flow while effectively capturing dust. With the capability to remove most harmful airborne particles (>5 microns) in your home, it offers longer lasting filtration for both you and your HVAC system.

Castle Filters utilize patented filter technology, incorporating 3 layers of ¼-inch open-celled foam with a patented tacky center layer that attracts dust like fly paper. As an added bonus, they are proudly made in the USA under US patent# 10,183,249 B2.

With a MERV 6 rating, the Super-Flow MERV 6 air filter offers a viable alternative to traditional see-through woven fiberglass or washable filters. It provides superior protection for your equipment and home, while still allowing maximum air flow.

Castle Filters feature an AC air filter with 400% more surface area for dust and other particles to collect. The internal foam is treated with a sticky material to effectively capture more dust, while still allowing air to pass through.

In comparison to pleated filters that need to be replaced monthly, the Castle Air Filter has the capacity to hold up to 20 times more dust and lasts for one year, which is 4-12 times longer than other filters.

By using Castle’s HVAC air filter, you can save energy with its advanced filtration technology and contribute to generating less waste, as it does not need to be changed every month like a standard filter.
