Reverse Osmosis FAQs

What is reverse osmosis and why is it used for water purification?
Reverse osmosis is a process that uses a special membrane to remove impurities and contaminants from water. It is commonly used for water purification because it effectively removes harmful substances, providing clean and safe drinking water.

Reverse osmosis is considered one of the most effective water filtration methods available. It can remove a wide range of contaminants, including heavy metals, bacteria, viruses, and chemicals. Other filtration methods may not be as thorough in removing these impurities.

Reverse osmosis systems do produce some wastewater as part of the purification process.

However, newer systems are designed to be more efficient and minimize water waste.

The amount of wastewater produced will vary depending on the specific system and water conditions.

Reverse osmosis does remove minerals from water, including beneficial ones like calcium and magnesium.

While this may not be an issue for most people, some prefer to add minerals back into the water for taste or health reasons.

There are remineralization options available for those who want to add minerals back into their purified water.

It is recommended to test the quality of your reverse osmosis water at least once a year.

This will help ensure that the system is functioning properly and effectively removing contaminants.

Our experts can provide guidance on testing frequency based on your specific water conditions and usage.
