Frequently Asked Questions
What's the difference between the residential RO systems listed here and a water softener?
Reverse osmosis removes dissolved solids, chlorine, and contaminants from your drinking water at the point of use, producing purified water for drinking and cooking. A water softener treats your whole home's water supply to remove hardness minerals like calcium and magnesium. Many households use both together: a softener for the whole house and an RO system at the kitchen tap.
How do I choose between an under-sink RO system and a whole-house filter?
Under-sink RO systems treat water at a single tap, ideal if you mainly want purified water for drinking and cooking. Whole-house filters treat all water entering your home, protecting plumbing and appliances and improving water at every fixture. If your water quality concerns extend beyond drinking water, a whole-house system paired with an RO system at the kitchen sink gives the most complete coverage.
Do these residential systems require professional installation?
Most AMPAC USA residential systems are designed for straightforward installation with basic plumbing skills, and include instructions for connecting to a standard water line. Whole-house systems and softeners involve larger connections and a drain line, so many homeowners choose professional installation for those, while under-sink RO and countertop units are commonly self-installed.
How often do residential filters and membranes need replacement?
Replacement intervals vary by system and household water usage. Pre-filters in RO systems typically need replacement every 6-12 months, RO membranes every 2-3 years, and UV lamps annually. AMPAC USA's replacement filter kits are sized to match each system so maintenance stays predictable.
Can I mix and match systems, like a softener with an RO system and a UV disinfection unit?
Yes. Softeners, RO systems, and UV disinfection units address different water quality issues and are commonly combined: a softener protects plumbing and appliances from scale, an RO system purifies drinking water, and a UV unit disinfects against bacteria and pathogens. AMPAC USA's residential product lines are designed to work together as a complete home water treatment solution.
