OMNIFilter TO1 Carbon Whole House Replacement Filter Cartridge, 10" x 2.5", 5 Micron — Pack of 2, Carbon-Wrap Sediment & Taste Con

The Pentair OMNIFilter TO1 is a 10" carbon-wrapped replacement cartridge that removes sediment and reduces chlorine taste and odor for whole-house chlorinated water systems.

Whether you want clearer tap water for cooking, brighter-smelling showers, or reduced particles in fixtures, the OMNIFilter TO1 combines a cellulose core with a carbon outer wrap to deliver both particulate capture and taste-and-odor control in one standard 10" x 2.5" cartridge. Each filter is rated for approximately 15,000 gallons (about three months of typical household use) and comes in a convenient two-pack so a spare is on hand when it’s time to swap cartridges.

How does this cartridge reduce both sediment and chlorine taste?

The TO1 uses a dual-layer design: a cellulose core traps fine particles while an activated-carbon outer wrap adsorbs chlorine and volatile compounds that cause taste and smell problems. That combined approach lets the cartridge handle multiple common issues without needing separate sediment and carbon stages.

• 5-micron nominal particle capture for fine sediment, rust, and scale particulates.
• Activated carbon surface bonded to the cellulose for chlorine adsorption.
• Single-cartridge solution replaces two-step filtration in many setups.

Will this fit my whole-house filter housing?

TO1 cartridges are built to the standard 10" x 2.5" size and are compatible with Pentair OMNIFilter U24, U25, and U30 systems. They also fit most other manufacturers' housings that accept standard 10" cartridges, making them an easy retrofit option for many homes.

• Standard 10" length and 2.5" diameter sizing.
• Compatible with OMNIfilter U24, U25, U30 and many third-party housings.
• Simple drop-in replacement—no tooling beyond housing wrench usually required.

How long will each cartridge last and when should I replace it?

Each TO1 cartridge has an estimated capacity of 15,000 gallons, which typically corresponds to about three months under average household usage and municipal water conditions. Replace sooner if you observe reduced flow or a decline in water clarity or odor performance.

• Rated ~15,000 gallons per cartridge under typical conditions.
• Replace roughly every 3 months or when flow decreases.
• Keep the included spare cartridge ready for quick swaps.

Is this cartridge suitable for my water source?

The TO1 is engineered for use with chlorinated municipal water supplies where chlorine and particulate matter are the primary concerns. It is not formulated for untreated well water with heavy biological or iron contamination; specialized media may be needed in those cases.

• Optimized for chlorinated city water systems.
• Effective for sediment, rust particles, and chlorine-related taste and odor.
• Not designed as a replacement for specialized iron, bacteria, or heavy-metal treatment cartridges.

Who is this for? The Pentair OMNIFilter TO1 10" carbon wrap cartridge is ideal for homeowners with municipally treated water who want a straightforward, cost-effective replacement that improves tap water taste and captures fine sediment. It suits anyone using standard 10" whole-house housings—especially existing OMNIFilter U24/U25/U30 owners—who prefer a single cartridge to address both particle and chlorine-related smell or taste issues. If you need long-term heavy-duty iron removal or bacteriological filtration, consider pairing the TO1 with additional targeted cartridges or a professional water analysis to select the right media for your system.
