Frequently Asked Questions related to Water Filtration
Q. What is reverse osmosis (RO)?

A. A hyper filtration process that reverses the natural tendencies of water and salt movement and forces clean water to flow through a semi-permeable membrane (0.0001 micron) by overcoming the osmotic pressure. RO systems remove substantial amounts of salts and contaminants from water, where water pressure is what forces water molecules through the membrane. Many drinking water systems or DI systems, especially in areas where water has high salt content or water quality issues, use RO membrane as one stage in the filtration process.

Q. How does an RO membrane differ from sediment and carbon filters?

A. Sediment water filters use a porous medium (e.g., polypropylene) to mechanically separate suspended particles (e.g., dirt) from water. Carbon filters/cartridges will adsorb some chemicals (e.g., organic compounds, chlorine). Carbon block filters will also serve as sediment filters. An RO membrane is a semipermeable membrane that removes an extremely high percentage of dissolved salts from tap water. Normally, an RO system will have sediment and carbon filters before the RO membrane and a carbon filter as a post filter.

Q. How is RO water compared to bottled water?

A. Bottling plants use the same technology, reverse osmosis (RO) filtration, to purify water. Some bottling plants add selected minerals to water for improving the taste. Similarly, some RO systems have alkaline filters added for the same reason: improve taste and raise pH.  In bottling plant minerals are injected in water using metering pumps and plastic bottles are used as containers for water. Some of them add ozone to water for long term shelf storage. Alkaline filters normally start effective and their effectiveness reduce with time, thus routine replacement is needed similar to other filters.

Q. Is it easy to install the RO System or another filtration system?

A. If you can follow instructions, you will be able to follow the Installation Manual that comes with the product. Technical support is available. A handyman or plumber will be able to install the system in less than an hour.

Q. If I move, can I remove the filtration system to take with me?

A. Our systems are easy to uninstall. There is no need to completely uninstall; just take off the water inlet tubing, close out the water inlet shut off valve, and take off the whole system in 5 minutes. It is wise to leave the faucet in place for others to use. You can order a new faucet, feed valve and drain clamp for use in your new residence.
