Best in Class Filters

The Water4Life filter delivers one of the most efficient flow rates and the highest level of water purification available on the market today.

The Water4LIfe™ filter uses Hollow Fiber Membrane (HFM) technology, a proven, simple, and highly efficient way to purify water without chemicals or power.

Introduced broadly into the market in the 1960s, hollow fiber membranes are widely used in water treatment and medical applications, including kidney dialysis.

Made with many U-shaped micro-tubes with semi-permeable pores, the Water4Life filter features 0.1 micron absolute pores. As the water flows through these tiny pores bacteria and protozoa are trapped, and clean water passes through.

Key Features

A Complete System

Use the filter with one bucket, in a two bucket system, at a faucet, on a bottle, or inline under the sink or a refrigerator filter line
Required adapters and different size hoses all included in the kit to address site-specific needs

Tests and Ratings

Every cartridge is individually tested to ensure quality and verify the 0.1 Micron Absolute rating
Three 3 O-rings virtually eliminate leaking around the cartridge — competitors typically have 1 or 2 O-rings

Adapters Included

Attach the universal adapter to ensure clean water from a tap or faucet, or water collected in a bottle from any water source

Eliminate Recontamination

Eliminate recontamination of clean water by using a two-bucket system to store clean water, or the included inline clamp to stop the water flow when using a water line

Easy Backflushing

Weekly backflushing is required to maintain the filter’s flow rate and efficiency
An included syringe efficiently pushes clean water through the membrane to clear it of contaminants and debris
Universal threads on the filter can also be used to fit readily-available water or soda bottles to backflush the cartridge

Available Pre-filter

High turbidity (suspended sediment in the water) damages hollow fiber membranes over time
Where turbidity is high, add a pre-filter to extend the life of the membrane
Optional pre-filter is made of reticulated carbon foam to reduce chemicals, heavy metals, and viruses and silver to prevent biofilm from forming on the carbon foam
