The Watts Premier RO-Pure Reverse Osmosis System is a 4-step reverse osmosis system designed to fit under your sink. The first step in the system is a 5 micron sediment filter. This filter is intended to trap small particles that may be found in tap water like dirt or rust. The second component of the system is a 5 micron carbon block filter. This second filter is intended to trap certain chemicals that may be found in tap water like chlorine. The third component of the system is the reverse osmosis membrane. As with other reverse osmosis filters, water is forced through the membrane, trapping many contaminants ranging from microorganisms to chemicals. Since reverse osmosis can be a slow process, the system also has a storage tank to collect filtered water before you are ready to use it. The final step is a second carbon filter, designed to remove any remaining impurities from water that has been sitting in the storage tank.
Price: $180 on Amazon
Replacement filters cost: $53 for an annual pack on Amazon
Upkeep: Filters should be replaced ever 6 or 12 months, but the RO membrane lasts between 2-5 years
Protection: As with most reverse osmosis filters, the Watts Premier RO-Pure Reverse Osmosis System is very comprehensive for purifying tap water. It includes most purifying strategies you might be looking for, including a sediment filter, activated carbon filter, and a reverse osmosis filter.
Pros: As with other RO systems, many people prefer the taste of their water after filtration with this system. Additionally, as with many RO systems, the Watts Premier RO-Pure Reverse Osmosis System has a high rating at removing a variety of contaminants including bacterial cysts, arsenic, lead, fluoride, and other chemicals. However, one advantage of this system over other RO systems is its filter design. Each of its four filtration components snap in separately to the system, allowing for easy removal and replacement. Because some of these filters will need to be replaced every 6 months, the ability to quickly and easily replace them yourself can be very beneficial.
Cons: Additionally, many customers have noticed leaks in their system, which may be due to improper installation.
In comparison to other RO systems, the installation and filter replacement is much simpler, though improper installation can lead to leaks.
