FAQ for Our Water Filtration Products
Q: What system should I choose for city water vs well water?
A: City water often needs sediment and carbon filtration for taste and odor. Well water often requires sediment filtration and may also require UV disinfection.
Q: Whole house vs under sink, what is the difference?
A: Whole house filters water at every tap. Under-sink filters for drinking and cooking water at one sink.
Q: What does UV purification do, and when do I need it?
A: UV disinfects water by inactivating microorganisms. It is most common when well water is used or when disinfection is needed.
Q: How often do I replace cartridges, RO filters, and UV lamps?
A: Replace filters on a schedule based on usage and water quality. UV lamps are typically replaced yearly.
Q: Will filtration reduce water pressure?
A: It can if the system is undersized or the filter is clogged. Proper sizing and timely replacement help maintain flow.
