Description

Patented Filter Technology: Castle Filters use 3 layers of ¼-inch open-celled foam, with a patented tacky center layer that catches dust like fly paper. Proudly made in USA - US patent #10,183,249 B2

MERV 8: The High-Flow MERV 8 air filter effectively removes 93% of the most harmful dust particles and offers superior protection of your equipment and home while still allowing maximum air-flow

HVAC Filter: Castle Filters have 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 letting the air pass through

Lasts One Year: The furnace filter holds 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 one year which is 4-12x longer than the others

Save Energy and Lower Land Fill Contribution: Castle Air Filter helps you save energy with its advanced filtration technology and also helps in generating less waste as it need not be changed every month like a standard filter

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $31 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Castle Air Filters products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
