LifeStraw Replacement Membrane Microfilter Cartridge for Home Pitchers — Removes Bacteria, PFAS, Microplastics

LifeStraw Home replacement membrane microfilter is a drop-in cartridge that removes bacteria, parasites, microplastics, PFAS and 30+ contaminants to give your LifeStraw pitcher or dispenser consistently safer, better-tasting water.

Swap in this certified membrane microfilter to upgrade your existing LifeStraw Home pitcher or dispenser. Engineered to target microscopic biological contaminants plus persistent pollutants and microplastic fragments, the filter extends the life and effectiveness of your household filtration system while cutting single-use bottled water consumption. Each cartridge treats up to 264 gallons—roughly one year under typical family use—before replacement.

How does this filter protect against bacteria and parasites?

The membrane microfilter uses a fine physical barrier that captures bacteria and protozoan parasites without relying on chemicals. Because it mechanically removes these organisms, it reduces health risks associated with microbial contamination in municipal and non-municipal supplies.

• Physical membrane pore size designed to trap bacteria and protozoa
• Removes organisms without adding chemicals or altering mineral balance
• Compatible with LifeStraw Home pitchers and dispensers for continuous protection

Will it reduce PFAS, microplastics and other industrial contaminants?

Yes—this replacement cartridge targets a broad range of non-biological contaminants, including microplastics and certain persistent organic compounds commonly called PFAS. While no single consumer filter removes every chemical, this membrane significantly lowers many of the most concerning particles and compounds found in tap water.

• Reduces microplastics and visible particulate matter for clearer water
• Lowers levels of PFAS and other selected chemical contaminants
• Improves taste and odor by removing suspended and dissolved impurities

How long does one filter last and how do I know when to replace it?

Each LifeStraw Home membrane microfilter treats up to 264 gallons of water, which is roughly one year for typical household use. Flow rate decline, noticeable taste changes, or visible discoloration are practical signs it’s time to swap the cartridge.

• Rated lifespan: 264 gallons (approx. one year with normal use)
• Monitor flow and taste—reduced flow or off-taste signals replacement
• Easy to replace: designed as a drop-in cartridge for LifeStraw Home units

How does this cartridge help reduce single-use plastic waste?

By extending the life of your pitcher or dispenser and providing reliable filtration at home, the cartridge makes it practical to choose tap water over bottled water. That reduces plastic bottle purchases and the associated disposal footprint.

• Enables consistent, high-quality tap water that replaces bottled water needs
• One product purchase supports safe water for a child for one year through LifeStraw impact programs
• Compact, replaceable cartridges reduce packaging and waste compared with bottled water

Who is this for: Families and individuals who already own a LifeStraw Home pitcher or dispenser and want a reliable, drop-in replacement that targets biological pathogens, microplastics, and a range of chemical contaminants. It’s also suited to those seeking a practical way to improve tap water taste while cutting bottled-water waste and supporting LifeStraw’s one-for-one impact model.
