What does the lifetime warranty cover?+

Is installation really free?+

How long does installation take?+
Most whole-home systems are fully installed in 3–5 hours. Our certified technicians work cleanly, test everything before they leave, and haul away any packaging or old equipment.
What is a whole-home water filtration system?+
It filters water at the main point of entry, so every tap in your home — drinking, cooking, bathing, and cleaning — delivers clean, filtered water.
How does reverse osmosis work?+
RO pushes water through a semipermeable membrane that removes chlorine, heavy metals, and other impurities, producing purified water for drinking and cooking.
How often should I replace filters?+
Most systems need filter changes every 6–12 months. We'll provide a tailored schedule for your specific equipment.
What contaminants does Ascend remove?+
Chlorine, lead, heavy metals, pesticides, sediment, bacteria, and many other harmful contaminants — protecting your entire home.
Will it affect my water pressure?+
No. Our systems are sized and engineered to maintain strong, consistent pressure throughout your home.
