Description

Individually wrapped, high capacity, top quality filter replacement cartridge pack for iSpring PH100, RO100 and most industry standard 10” reverse osmosis RO systems. Made in the US.

Experience clean, safe, and delicious water every time you turn on the faucet.

Sediment Water Filter: Works as the first barrier in the reverse osmosis system by removing solid particles like silt, rust and dirt from the water and reducing a significant percentage of contaminants in the water. This prevents the other filters from getting clogged with fine particles and reduces the risk of damage to the other parts of the filtration system.

Granular Activated Carbon Filter: Includes high quality carbon media that filters out impurities in the water. This protects and prolongs the lifespan of the reverse osmosis membrane.

Carbon Block Filter: Activated carbon filters trap and absorb organic chemicals and chlorine from the water. This results in the removal of odors and an improvement on the taste of the water.

Post Activated Carbon Filter: Captures any particles that may have accumulated inside the tank before pure water is delivered to the faucet. It will last up to 12 months depending on the incoming water source and personal usage.

4 pack of 10” x 2.5” replacement water filters included: 1x Sediment Filter, 1x Granular Activated Carbon Filter, 1x Carbon Block Filter, and 1x Post-Carbon Filter. All filters are made in the USA.

Note: This filter pack does NOT include an RO membrane.

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 $12 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 iSpring 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.
