Comparing different options can be difficult because many reverse osmosis systems that are under-sink appear similar. All RO systems follow the same basic principles. The water is passed through multiple filters and an RO membrane to remove almost all impurities. The membrane quality and filter can have a significant impact on the system’s performance and taste.
Compare the life of different RO systems. Also, check for the number of stages and the presence of mineral filters. These are the most important features to look at when searching for the best reverse osmosis system for your home. The most basic RO system should include at least five stages. These are:
Three pre-filters: There are usually one sediment filter and two carbon filters. These filters remove organic chemicals as well as chlorine. These filters protect the RO membrane from damage and clogging. RO membrane This membrane is the heartbeat of the system. It removes the most challenging contaminants such as heavy metals, dissolved salts, and other harmful substances.
The post-filter polishes water before it leaves your faucet. It removes unpleasant tastes and odors. A faucet with five stages produces non-mineralized water. The membrane has eliminated all minerals, even good ones.
The filter life is one of the most reliable indicators of filter quality.
Water purification systems less expensive than premium RO systems are often just as effective in purifying water. You will need to change the filters more frequently, usually every 3 to 6 months.
Every 1-2 years, the membrane must be replaced.
This makes maintenance more challenging and increases the overall cost of the system. Filters in higher-end systems may last up to one year. Some RO systems can last for as long as 5 years. The membrane can last for 2 years. If you don’t have to replace filters every few years, it’s not worth spending more on an RO system.
DAILY CAPACITY
Another important factor to compare is the amount of water each RO system produces daily. This is the daily water output in gallons per day (GPD). An average RO system can produce 70-100 gallons of water per day. This is sufficient to provide water for most families, even large ones. RO water is required to do more than just drinking.
WATER EFFICIENCY
Reverse osmosis water systems all produce wastewater. The RO membrane has accumulated pollutants in the drain water. If the membrane is not flushed frequently, it will eventually fail to function. However, some RO systems waste far more water than is necessary. Sometimes backpressure is the cause. The tank is kept under pressure so that water cannot get inside. This is particularly true when the tank fills up. The drain will take some of the water out.
Most RO systems have a water loss ratio of 3:1. This means that 3 gallons of purified water must be drained for each gallon. You can spend a little more for a high-efficiency system with a lower waste ratio such as 1:1 or 2:1. Low-wastage systems might include an integrated permeate pump that helps water overcome the pressure and ensures more goes into the tank. A permeate can be added to an RO system, or a booster pump can be added to any RO system. If you don’t already have one, don’t be discouraged. It is possible to get it later.
BUILD QUALITY
The quality of the RO system’s construction is important. Before an RO system is purchased, it’s difficult to determine its build quality. You should verify the warranty length and review customer comments.
RO systems that are made from high-quality components often have a longer warranty. RO systems that cost less often have a 1-year warranty. They may not last as long.
Check out customer reviews to see how components have performed. Some RO systems are so popular that customers claim they had to buy their own parts in order to replace the ones supplied by the manufacturer.
