BOROUX Foundation Filters have been tested by IAPMO R&T Lab NJ, an ISO/IEC 17025 recognized laboratory.

Fluoride
BOROUX Proactive Filters do effectively filter fluoride. Specially designed to block up to 99% of this concerning toxin. The BOROUX Fluoride Filters connect to the BOROUX Foundation Filters for multi-step filtration.
BOROUX Foundation Filters do not effectively filter fluoride. The test results showed that fluoride was filtered for a few gallons, but not enough to claim it’s effectively removed.
Fluoride is a particularly difficult contaminant to separate from water due to its small molecular size, electrochemical charge, and solubility.
Arsenic
We have not yet tested for arsenic.
