Why Woder?
Woder is all about water
We’re water-filter specialists. Our only goal is to make certain you have water filters that assure you of pure, healthy drinking water on tap.
The Woder advantage
Selective Filtration™
Woder filters have a unique technology that removes over 99.99% of contaminants while leaving in all essential minerals, which are vital to your health, including calcium, potassium, and magnesium. The unique advanced Selective Filtration™ technology has an affinity for impurities, so it attracts them, but it has no affinity for healthy minerals, so it allows them to remain. By contrast, residential filters that work with reverse osmosis filter out everything, including the minerals your body needs for good health. As far as nutrition goes, experts consider it essentially dead water.
Large capacity
The precision-ground nanoparticles have another advantage. Many more can fit in a Woder filter, and Woder lets you enjoy the benefit, instead of making the filters smaller. As a result, a Woder filter lasts a minimum of 3 years with normal use, while many ordinary filters last only 6 months to a year.

Spring-like freshness and healthfulness
Pure, healthy water that nature intended for you
All Woder filters are manufactured in the United States to the highest quality-control standards. There are many purely scientific reasons to choose a Woder water filter. But the most important reason of all is your concern about the quality of the water you and your family are drinking or, if you’re an employer, the quality of the water your employees and customers are drinking. Woder filters deliver the pure, healthy water that nature intended for you, your family, employees, and customers to drink.
Woder filters are tested by independent laboratories to ANSI standards (American National Standards Institute), so you can have complete confidence in the quality of Woder-filtered water. ENJOY TAP WATER AS PURE AND HEALTHY AS SPRING WATER 
Works for your refrigerator, too
Woder makes a special filter for your refrigerator. While refrigerator makers promote their own costly original in-fridge filters and some manufacturers even require the original filter to be installed for water to flow, a Woder filter can produce purer, healthy water for your fridge or icemaker – and last much longer than the original filter. (If you’re refrigerator won’t work without the original filter in place, just leave it there and connect your Woder filter for superior. Long-lasting results.)
Woder offers a 100% 1-year guarantee. We can do it because our filters are made to perform and last as described. If you ever experience a problem, simply contact us. We’ll either solve it or provide a complete refund. No questions asked.
