    About Omnipure

    Who makes the Best Inline Water Filter in the world?  Omnipure Filter Company!  This was done by revolutionizing the water filtration industry via making the first small disposable inline carbon filter for water that tastes better.   All of their products are manufactured (over 20,000 filters per day!) in house in Caldwell, Idaho and distributed worldwide.

    OmnipureFilter Co. was established in 1970 when engineer William Reid designed and built the world’s first disposable inline water filter. His engineer son Roger eventually earned his place to lead the company since Roger developed several cutting-edge filter body designs that again revolutionized the industry. Omnipure commits daily to service and quality of their epic inline water filters.

    Water eStore carries Omnipure products for various applications.  We vet our suppliers and personally test all Omnipure products, installing them in our homes (where applicable) and monitoring their performance daily. They have earned their reputation as innovative products with top notch customer service.  

    Omnipure products are easy to install and service. We offer YouTube videos that support Omnipure products explaining how they work, how to install and service. We also offer a 100% money back guarantee if you’re not satisfied with your investment in Omnipureproducts for your family.
