Alkaline Water Filter Machine

Water is pre-filtered

Your under sink system takes in water and uses a pump to feed it through an initial filter. This process reduces the presence of sediment particles like rust and dirt while addressing chlorine odors, unpleasant tastes and more.

Reverse osmosis occurs

Once the pre-filtration step is complete, water flows to your system’s reverse osmosis chamber. This chamber houses the semipermeable RO membrane. Your water is forced forward at high pressure, and the membrane acts like a net to trap certain contaminants and filter them out of your water supply. Different systems have different degrees of accuracy at this stage; for example, the high-capacity membrane in Culligan RO systems can reduce up to 95% of substances.

Your water is filtered again

Although this step isn’t offered by all systems, a good under sink filter allows you to add specialty filtration to the overall process. For example, some Culligan systems can utilize a mineral boost cartridge that could increase your water’s pH, creating an almost limitless supply of alkaline water. You could also install Culligan’s Total Defense cartridge to address lead, mercury and certain other contaminants.

The wastewater is drained

While your water is going through the final filtration stages, your under sink system is draining waste water. This waste is created during the reverse osmosis process. Some systems are designed to waste less water, so look for high-efficiency filtration solutions that don’t drive up your water bill.

Filtered water is stored

Although some tankless reverse osmosis systems skip this step, most store your filtered water in an attached tank. That way, your cleaner, purer-tasting water is ready to go at a second’s notice.

You turn on the tap

Finally, it’s time for a drink. The system might even use one more filter time to further improve taste before the water hits your glass.
