How To Compare Reverse Osmosis Systems

It can be difficult to compare different options because most reverse osmosis systems that are under-sink look similar. All RO systems have the same basic principles. To remove nearly all impurities, the water goes through several filters and an RO membrane. The quality of the membrane and filters can make a huge difference in the performance and taste of the system.

When comparing different RO systems, make sure to check the filter life, a number of stages, and presence of a mineral filter. These are the top features to consider when looking for the best reverse osmosis system in your home. At least five stages should be included in the most basic RO system. These are:

3 pre-filters: Typically, there is one sediment filter and 2 carbon filters. These filters remove organic chemicals and chlorine. They protect the RO membrane against damage and clogging. RO membrane The membrane is the heart of the system. It is responsible for removing the most difficult contaminants, such as heavy metals and dissolved salts.

The post-filter Polishes water before it leaves the faucet. It removes any odors or tastes. Non-mineralized water comes out of a faucet that has five stages. The membrane has removed all minerals, even the good ones.

The Filter Life is one of the best indicators for filter quality.

Water purification systems that are less expensive than premium RO systems can often be just as effective at purifying water as those with higher quality filters. However, you will need to replace the filters more often, usually every 3-6 months.

The membrane will need to be replaced every 1-2 years.

This makes maintenance more difficult and also increases the cost of the system over time. However, filters in higher-end systems can last for up to one year. The membrane can be used for up to 2 years, and some RO systems can last up to 5 years. It’s not worth it to spend more upfront on a high-quality RO system if you don’t need to replace filters every few months.

DAILY CAPACITY

The amount of water that each RO system produces per day is another important aspect to consider when comparing them. This is the daily water production, expressed in gallons per hour (GPD). The average RO system produces 70-100 gallons per day. This is enough to supply most families, even large ones. You will need RO water to do more than drinking.

WATER EFFICIENCY

All reverse osmosis water systems produce wastewater. The RO membrane has accumulated contaminants in the drain water. The membrane will eventually stop working if it isn’t flushed regularly. Some RO systems, however, waste far more water than is needed. Backpressure is often the reason. The tank is pressurized so water can’t get in. This is especially true as the tank fills up. Some of the water is drained down the drain.

The water wastage ratio for most RO systems is 3:1. This means that for every gallon of purified water, 3 gallons must be drained. Spend a little more to get a high-efficiency system that has a lower wastage ratio, such as 2:1 or 1:1. Low-wastage systems may include integrated permeate pumps that help water overcome back pressure and ensure more goes into the tank. You can add a permeate to your RO system or a booster pump to any RO system. Don’t worry if you don’t have one. It’s possible to get it later.

BUILD QUALITY

Consider the quality of the RO system’s build. It is difficult to assess the build quality of an RO system before it has been purchased. Make sure you check the warranty length and read customer reviews.

RO systems made with high-quality components usually have a longer warranty. RO systems that are less expensive often come with a 1-year guarantee. They might not last as long.

Read customer reviews to find out how well different components have held up. Some RO systems have customers who claim they had to purchase their own parts to replace those supplied by the manufacturer.
