💬 Additional Notes

For fluoride removal, we recommend pairing this system with the UltraStream drinking water filter, as whole house fluoride removal requires slow contact time

Most customers add an UltraStream system at the kitchen tap to improve taste, colour, and odour

Filter life depends on usage and water quality – replace every 6–12 months

Looking for other whole house filter options?

We offer a range of systems tailored to different water sources and concerns—whether you’re dealing with high sediment, iron, bacteria, or specific chemical contaminants.
