What to Look for in a Water Distiller

Not all distillers are created equal. Here are the key factors that separate a premium distiller from the rest, and why they matter for your family's health and your home.

Safety Certification

CSA/UL certification is required by insurance companies. Without it, a fire or flood claim involving your appliance could be denied.

Build Quality

Stainless steel throughout: boiling tank, coil, and faucet and the largest impurities drain on the market.

Reserve Capacity

More storage means you're never without water. Larger tanks ensure your family has distilled water on demand, even during peak usage.

Warranty Coverage

2-year parts and labor warrany and 15-year stainless steel warranty.

Entire waterpath is Stainless-Steel

Beginning with the solenoid fill valve to the evaporator, condensing coil, post filter cup, reserve tank, water level gauge and dispensing faucet.

Why CSA/UL Certification Matters

All electrical appliances in your home must carry recognized safety certification (CSA/UL) to remain covered under your homeowner's insurance policy. In the event of a house fire, flood, or other disaster involving an uncertified appliance, your insurance company may legally deny your claim. Precision Water Distillers are the only North American water distillers that currently meet CSA standards, giving you peace of mind that goes far beyond pure water.
