- Water tastes and looks excellent (and has no odor)
- 3 gallon storage tank so water is always ready when you need it
- Quieter than competitors’ five-stage models
- Removes many heavy metals, cysts, and other known impurities
- Good value for the money
- Instruction manual is unhelpful and at times incorrect
This 5 Stage Reverse Osmosis Water Filter System is made by Crystal Clear, a company that specializes in water filtration systems for homes and businesses. This system is installed underneath the countertop, in the space below the sink. It attaches to the water supply piping then runs that water through a five-step series of reverse osmosis and several various filters.
The water is then routed to a storage tank, which can hold up to three gallons at one time for immediately available water. Excess water is always created through the reverse osmosis process, so there is a second tube that takes waste water and runs it down the return drain, with the rest of the water that goes down the sink.
Unlike some other reverse osmosis systems, the 5 Stage Reverse Osmosis Water Filter System from Crystal Clear does include an automatic shutoff valve. Once the 3-gallon storage tank is full, the valve will disconnect the system from the water supply so that no excess water is drained off without reason. There is still waste water produced, but not as much was with other systems.
In terms of water quality, clarity, and taste (which is the reason most people buy such a product), this 5-stage filter gets very good reviews from customers. The manufacturer states that it is designed to remove sediment, rust and other particles, dissolved solids (including a number of heavy metals such as barium, lead, mercury, chromium, and cadmium), chlorine, organic impurities, and organic cysts (including cryptosporidium, which can cause diarrhea). This system also removes fluoride, which many other systems do not do.
The only major complaint that owners have with the 5 Stage Reverse Osmosis Water Filter System by Crystal Clear is that it is difficult to install. The manual that comes with the product is unclear and at times incomplete. At other times, the manual provides instructions for a different model, and so the instructions do not apply. Users report having to search online for instructions, and in some cases have hired a plumber to install the system for them after much frustration.
However, once installed, Crystal Clear’s 5 Stage Reverse Osmosis Water Filter System gets very high marks from users. It is also quieter than some 5-stage filtration systems, which is an added advantage.
Bottom line: This 5-stage under-the-sink Reverse Osmosis Water Filter System from Crystal Clear does an excellent job of improving water quality and removing harmful contaminants. It features an 3-gallon storage tank and an attractive sink-top faucet dispenser, separate from the primary kitchen faucet. Though it comes with poor instructions, once it is installed owners report years of consistent performance and great pleasure with the water quality.
