Frequently Asked Questions
How often should I clean and replace my filters?
Clean the stainless steel chambers and spigot monthly. Scrub and re-prime Foundation Filters every 3–6 months, or sooner if flow slows. For consistent performance across varying water sources, we recommend replacing Foundation Filters about once every 12 months.
Are Proactive Fluoride Filters included with my system?
Proactive Fluoride Filters are an optional add-on. Your BOROUX system works without them, but fluoride reduction requires Proactive Fluoride Filters. Please check your order confirmation to see whether they were included with your purchase.
My filtered water tastes or smells unusual—what should I do?
A change in taste or odor can be related to the water source, mineral buildup, recent installation, filter priming, or cleaning needs. Empty the current batch, clean the system as directed, and refill. If the issue continues, please contact us with details about your water source, filter age, and setup so we can troubleshoot with you.
Can I use my BOROUX system with softened water?
We do not recommend using water that has passed through a salt-based water softener. The added salts can prematurely clog Foundation Filters and shorten their lifespan. If your home has a whole-house softener, use an unsoftened cold-water line or bypass for water going into your BOROUX system
Can I use my BOROUX system with well water?
The Boroux Foundation Black Filters are designed to reduce a broad range of contaminants typically found in municipal tap water and can also address many issues present in well water, such as heavy metals, PFAS, pharmaceuticals, pesticides, chlorine, and more. However, these filters do not remove microorganisms, fluoride, or arsenic. If fluoride reduction is important to you, there is an optional Proactive Fluoride Filter add-on available.
