Why Apex?

Apex Water Filters is a family-owned and operated business based in Gardena, California, that manufactures the finest quality water filtration systems on the market. Although we ship our products all over the United States, we’ve managed to keep our business practices the same as they were when we opened our doors back in 1997.
When you choose an Apex water filter, you’ll get the absolute best water filter system for your needs from a company that values your business and will go above and beyond to ensure your full satisfaction. We are the number one choice for water filtration systems because:


Our products are fully compliant with the Safe Drinking Water and Toxic Enforcement Act.

Apex Water Filters complies fully with the requirements of the Safe Drinking Water and Toxic Enforcement Act of California. This law imposes strict requirements on all water filter systems sold in the state to ensure that California residents are protected from potentially toxic materials. Because we meet the standards of Proposition 65, you can be certain that the filter you purchase from us does an exceptional job at removing contaminants from drinking water.


We offer a huge selection of water filters.

With today’s innovative technologies, there are many ways that you can filter water in your home or business, and Apex Water Filters has water filter systems available to meet every need. From small counter top models for kitchens to large commercial filtration systems for office buildings, hospitals, schools and hotels, we have a filter that is perfectly geared toward your setting.


We only use the best materials.

At Apex Water Filters, we believe that the best water filters start with the best materials. That’s why we only use carbon that is certified by the National Safety Foundation and components that are approved by the U.S. Food and Drug Administration.
