Kirkland Signature Water Filter Cartridges – 8-Pack for Cleaner, Better-Tasting Water
Upgrade your hydration routine with Kirkland Signature Water Filter Cartridges, an 8-pack designed to fit Brita Maxtra+ pitchers and improve water quality easily and affordably. Engineered with activated carbon and ion exchange resin media, these cartridges reduce taste- and odor-causing chlorine, chloramine, hardness minerals, and certain heavy metals—while fitting seamlessly into popular pitcher systems.
Effective Filtration for Everyday Use
These filter cartridges are tested and certified to remove or reduce contaminants including:
Chlorine and Chloramine—common municipal disinfectants that can cause bad taste and smell.
Heavy Metals such as lead, copper, cadmium, zinc, benzene, and estrone, supporting safer drinking water.
Limescale & Hardness—helps reduce mineral build-up in kettles and improves tea and coffee flavor clarity.
These cartridges meet WQA and NSF standards for contaminant reduction and are engineered to deliver consistent performance over their lifecycle
Designed for Brita Maxtra+ Compatibility & Safe Materials
Fully compatible with Brita Maxtra+ pitchers, including older models that accept standard Maxtra+ filters.
Crafted from BPA‑free plastic, ensuring safe contact with potable water while contributing to durable, leak‑free operation.
Bundled as an 8-pack, providing about 1,200 gallons (≈4,500 L) of high-quality filtered water—with each cartridge rated for approximately 40 gallons or 150 L. Replacement is recommended every two months for best results.
Taste & Quality of Water
Users consistently report that filtered water tastes neutral or “clean,” and improves the flavor of brewed beverages:
Enhanced flavor of tea and coffee due to reduced chlorine and mineral off-notes.
A Reddit user noted that compared to older PUR filters, the Kirkland filters performed at least as well in taste and compatibility
For households with municipal chlorine-treated water, users often prefer one brand over another. Kirkland filters consistently perform on par with more expensive options.
Usage Instructions & Maintenance
Setup: Soak each new filter in cold water briefly, then shake and rinse to remove trapped air and carbon dust.
Installation: Insert firmly into pitcher reservoir, ensuring proper seat for correct flow.
First Use: Discard the first one or two pitcher volumes—normal carbon particles may appear initially.
Replacement: Change every 40 gallons (~150 L) or once every two months (for average usage).
Cleaning the pitcher and replacing filters on schedule helps maintain filtration quality and prevents build-up.
Why Choose Kirkland Signature 8-Pack Filters?
Exceptional value: Kirkland Brand filters are typically priced lower than branded competitors while maintaining performance standards.
Reliability: Many users confirm compatibility and effectiveness—even across Brita and in some cases PUR filter models
Bulk convenience: An 8-pack reduces frequent repurchasing and ensures a steady filtration supply.
Trusted sourcing: Manufactured to global standards, often tested in Europe (Germany origin in some markets) for consistent quality
Possible Considerations
Compatibility: Designed exclusively for Brita Maxtra+ style pitchers. May not fit other brands or older Brita filters.
Environmental impact: While filters improve water quality, they are plastic cartridges. Recycling availability depends on local programs.
Filter lifespan: Performance may diminish if used beyond the recommended capacity or time limit.
