FAQ

Common questions answered.

How long do the filters last?

The filter lifespan will vary depending on the source water and contamination level. The recommendation for when to replace depends on several factors. For example, for filtering chlorine, the filters last for 12,000 gallons per pair. See recommendations for other contaminants.

How do the filters work?

BOROUX foundation filters work by absorbing and trapping contaminant molecules. The carbon attracts and absorbs molecules with a certain chemical charge. They stick to the carbon, like how a magnet attracts metal. The tiny pores of the carbon block are so small that they physically block and trap tiny particles. It's similar to a sieve or strainer.

What is the BOROUX filter made of?

A specialized blend of activated carbon.
