Reverse osmosis (RO) water filtration is a purely mechanical filter process that adds no chemicals to the water. The incoming water is placed under pressure and forced through a semi-permeable filter with tiny pores. The contaminants are left behind on the surface of the filter membrane, and the water that passes through is virtually pure. In this article, we will take a closer look at RO filter systems to help you make informed choices.

Is a RO Filter System Affordable?

Reverse osmosis is an effective filtration system, but it’s more expensive than some other options on the market, and this makes it a less attractive proposition for many people. But, in most cases, we are talking about whole-house systems that can cost a lot of money. These systems supply virtually pure water to every fixture in the home, which is an amazing experience for those with the budget to install them. A more realistic option for most people is a point-of-use system.

What is a RO Point-of-Use System?

As the name suggests, this is a reverse osmosis filter that is installed at a single location. The usual position is at the kitchen sink, and a dedicated faucet is installed. The kitchen is a great location because the filtered water can be decanted into a pitcher for the refrigerator. Pans can be filled with RO water for cooking and washing vegetables and fruit using this water is very sanitary.

Is RO Water Convenient?

Yes, but there is a caveat. Forcing water through the semi-permeable membrane takes time, and an on-demand system is not practical. To solve this problem, the RO filter system uses a water storage tank that keeps the water clean until it’s needed. These systems have low maintenance requirements, but regular membrane filter changes are required.

Do I Need Any Other Filtration Systems?

The RO filtration system is effective, it removes many contaminants, but other systems are required. Some of these filters are built into the RO filter system. A pre-filter removes sand, sediment, and grit that can damage sensitive components. A granular activated charcoal (GAC) filter removes chlorine that can damage the filter membrane. The RO filter is next-in-line, and this is followed by a final GAC filter stage to polish the water for drinking and cooking.

Do I Need a Water Softener Too?

Yes, if you receive a supply of hard water, you’re not alone. Approximately 85% of the nation has the same problem in variable degrees of hardness. Hard water contains elevated levels of dissolved mineral content, which can cause a number of problems in the home. This includes the formation of scale that can damage water using appliances, including the RO water filtration system. For this reason, many people install a water softener and then add other systems to remove specific contaminants. The best way to determine your filtration needs is to carry out water testing.
