Pros & Cons

What We Like

  • True purifier — removes 99.99% of viruses, bacteria, and protozoa at 0.02 microns
  • 18,000-liter filter life provides years of clean water for a family
  • Incredibly affordable at ~$60 for virus-level purification
  • No electricity, batteries, or chemicals needed — pure gravity operation
  • Lightweight at 1.6 lbs — portable enough for bug-out bags or camping

Watch Out For

  • 9-12 L/hr flow rate is slow for larger families
  • Plastic construction feels less durable than stainless steel gravity systems
  • Does not remove chemical contaminants, heavy metals, or PFAS
  • Reservoir bag can be awkward to fill and hang without a hook
  • Must protect from freezing or hollow fiber membrane is compromised
