Frequently Asked Questions

How does the BOROUX legacy system work?

The BOROUX gravity-fed water filter system has one upper chamber and one lower chamber. The filters are installed in the upper chamber. Water is poured into the upper chamber, and then gravity pulls the water down through the BOROUX foundation filters and into the lower chamber. Drinking water can then be poured out from a spigot located at the base of the lower chamber.

How do the BOROUX foundation 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 legacy system made of?

foundation filters are a specialized blend of activated carbon
Chambers and spigot are 304 AISI stainless steel, which is food-grade quality and highly corrosion-resistant.
Stem Saver and hole plugs are BPA-free food-grade plastic
base ring and washers are food-grade silicone

When and how to do maintenance?

We recommend cleaning the stainless steel chambers and spigot monthly. The foundation filters should be scrubbed every 3-6 months or when you notice a slower flow rate.

Cleaning Instructions:

Remove foundation filters: Take out the filters and place them in a safe spot to avoid any damage.
Wash the Chambers: Using warm water and a mild dishwashing soap, wash the chambers, parts, and pieces by hand. Or, place the stainless steel chambers in the dishwasher.
Optional remove the spigot: If needed, detach the spigot from the lower chamber for cleaning. DO NOT use soap on the foundation filters.
Reassemble and enjoy: Once dry, reassemble your BOROUX legacy system and continue to enjoy refreshing water. Happy hydrating!
