Water Filters You Can Trust to Get Through Anything

  • Pure Water, Anywhere: Our system removes a broad range of harmful contaminants from nearly any water source. This means you have access to clean, safe water whether you're at home, camping, or facing an emergency.
  • Off-Grid Reliability: The Clearbrook filter is an essential item for power outages, remote travel, and preparedness kits because it works without any power. You can always count on it.

How Your Gravity Water Filter Works: Effortless Purification

Our gravity-fed filtration system makes purification simple. Just pour water into the top chamber, and let gravity do the work.

The water slowly moves through our advanced nano-filtration elements, giving the filters enough time to effectively remove impurities. What you get in the lower chamber is clear, purified water—a truly reliable alternative to expensive bottled water.
