Description

WHOLE-HOUSE HIGH-FLOW FILTRATION - This extra-large 20-inch housing holds 4.5" diameter Big Blue cartridges for whole-house, high-flow, and heavy-sediment applications, giving you greater capacity and fewer vessels at your point of entry.

HEAVY-DUTY CONSTRUCTION - Durable polypropylene sump and HFPP cap thread together with a single large closure and an EPDM O-ring; the large 1-1/2" NPT internal port passes a greater volume through the cap. No pressure-relief button on this model.

TESTED AND CERTIFIED - This housing is Tested and Certified by NSF International to NSF/ANSI Standard 42 for material and structural integrity; polypropylene housing and cap with an EPDM seal stand up to a broad range of chemicals.

CARTRIDGE COMPATIBILITY - Accepts 4.5" diameter, 20-inch "Big Blue" cartridges, so you can match the media to your water with large 1-1/2" NPT inlet and outlet connections for high-flow installs.

PRESSURE AND TEMP RATING - Rated to a maximum 90 psi and 40 to 100 degrees F for 20-inch sumps; protect against freezing to avoid cracking. Cartridge, mounting bracket, and wrench are NOT included and are sold separately.

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 $39 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 Pentek 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.
