FAQs

Why do you carry multiple brands instead of just one?

No single brand is best at everything. Some specialize in reverse osmosis systems, whole house filtration, commercial equipment, or wellness technology. We help simplify the process by offering trusted, proven solutions across every category so you can choose with confidence knowing your system is built to perform.
Why do some systems cost more than others?

Pricing varies based on number of filtration stages, system capacity (GPM / output), technology (RO, UV, hydrogen, etc.), build quality and components. Most systems range widely from a few hundred dollars to several thousand depending on features and performance. Higher-end systems typically offer better purification, longer lifespan, and more advanced features
Can I mix products from different brands?

Yes in most cases, systems are modular. You can combine whole house filtration + RO system, softener + conditioner, specialty wellness products. Just ensure filter sizes, flow rates, and connections are compatible. We recommended staying in the same brand to ensure efficiency and a void warranty.
