5 Stages of Filtration


100% BPA Free - Here's Why

BPA (bisphenol A) is a chemical that is added to many commercial products, including food containers and hygiene products. It was first discovered in the 1890s, but chemists in the 1950s realized that it could be mixed with other compounds to produce strong and resilient plastics.

BPA is said to mimic the structure and function of the hormone estrogen. Due to its estrogen-like shape, BPA can bind to estrogen receptors and influence bodily processes, such as growth, cell repair, fetal development, energy levels, and reproduction. In addition, BPA may also interact with other hormone receptors, such as those for your thyroid, thus altering their function.

Your body is sensitive to changes in hormone levels, which is the reason why BPA’s ability to mimic estrogen is believed to affect your health.


Our High-Pressure Pump Option

Most reverse osmosis systems lose 30% to 40% of their pressure during the reverse osmosis process. We prevent this by offering the option for a non-electric permeate pump that attaches to the top of our reverse osmosis system. This pump utilizes all NSF, WQA and FDA Certified components and allows you to install the system remotely in a basement or utility room. Never replace a refrigerator filter again - by adding the high-pressure pump option, you can connect your under sink RO to your refrigerator/icemaker, allowing you to enjoy a cleaner, clearer, and better-tasting ice and water experience.

4 Reasons To Choose 

  1. The Permeate Pump makes water twice as fast as an ordinary RO
  2. The Permeate Pump makes higher quality water than an ordinary RO
  3. The Permeate Pump wastes 80% less water than any ordinary RO
  4. The Permeate Pump delivers the highest pressure at the faucet of any RO - Ideal for ice-makers that need pressure.
