Filtration Efficiency

• Removes 99.999% of bacteria and parasites, and 99.99% of microplastics.
• In SGS laboratory testing, the tested OASSAY sample achieved >99.999% removal of MS2 bacteriophage, a surrogate used in virus testing. This result applies to MS2 bacteriophage under the conditions of that test and does not establish equivalent removal of all viruses in all water conditions. See our Safety and Performance Data page for the reported results.
• Improves water taste.
• Reduces organic pollutants, ammonia nitrogen, chlorine.

Flow Rate:

Filters 15–20mL/sec, depending on water quality and filter usage.

Warnings:

❗ Do NOT use with:

• Saltwater (ocean water), chemically polluted water, or water with visible oil
• Extremely turbid water — pre-settle for 30min before filtering
