Filtration guide
Water Filtration Technologies
Not all filters are equal — and the best technology depends on what's in your water. Here's how each one works, what it removes, and when to use it.
Most comprehensive — removes 95-99% of dissolved contaminants including PFAS, lead, arsenic, and fluoride.
Most common — removes chlorine, THMs, VOCs, and taste/odor. Does NOT remove TDS, nitrate, or fluoride.
Removes hardness minerals (calcium/magnesium) via ion exchange. Does NOT filter contaminants.
Kills bacteria, viruses, and parasites with UV-C light. Does NOT remove chemicals or minerals.
Swaps target ions for harmless ones. Used for softening, nitrate, radium, and PFAS removal.
Removes virtually everything by boiling and condensing. Very slow and energy-intensive.
Prevents scale without removing hardness. Does NOT soften water or filter contaminants.
No installation needed. Uses gravity to push water through ceramic or carbon elements.
