Aqua-Pure AP117 Whole House 3 in x 9.8 in Replacement Cartridge

Our review of the Aqua-Pure AP117 replacement cartridge finds it best for homeowners who want a straightforward, effective whole-house filter swap without changing housings. The cartridge is a drop-in, standard 3 in diameter by 9.8 in length design intended for AP100 and compatible stainless steel housings, and the single biggest reason to buy is its combination of sediment removal and improved taste - customers consistently report cleaner water and reduced chlorine odor after installation. Installation is simple, the fit is reliable, and the construction targets both particulate and chemical taste issues.

Key Features

• Sediment reduction: The polypropylene cartridge body and internal media are designed to remove sediment down to 5 micron nominal, helping protect plumbing and fixtures from particulates.
• Chlorine taste and odor control: High quality granular activated carbon increases adsorption surface area to reduce chlorine taste and offensive odors for better drinking and cooking water.
• Drop-in compatibility: Sized at 3 in by 9.8 in, the cartridge is a direct replacement for AP100 and standard or large diameter stainless steel housings, making swaps quick and tool-light.
• Sealing reliability: Santoprene gaskets on both ends help prevent bypass of unfiltered water by providing dependable sealing within housings.
• Regulatory materials: Materials are FDA CFR-21 compliant, assuring purchasers that contact materials meet common food-contact material standards.

Who It's For

The AP117 is ideal for homeowners with municipal or treated well water who need a simple whole-house sediment and chlorine taste solution that fits existing 10 in canisters and compatible stainless housings. It suits anyone who prefers predictable maintenance intervals and values a drop-in cartridge that saves time during replacement.

Those who need ultrafine filtration, specific contaminant removal beyond chlorine and sediment (such as lead, nitrates, or microbes), or a certified contaminant reduction for a particular chemical should look at specialty cartridges or multi-stage systems instead.

Pros & Cons

Pros

• Effective sediment capture to protect downstream fixtures and appliances.
• Noticeable reduction in chlorine taste and odor thanks to granular activated carbon media.
• Easy installation and reliable fit in standard housings, with durable Santoprene gaskets preventing bypass.
• Good value for money with customers reporting long service life between changes.

Cons

• Average cartridge life is about 6 months but actual life varies with incoming water quality, so more frequent changes could be needed in heavy sediment conditions.
