The iSpring RCB3P is a top-of-the-line reverse osmosis water filtration system that is perfect for commercial applications. The system features three high efficiency 100gpd reverse osmosis membranes that produce up to 300 gallons of filtered water per day. The unique combination of quality reverse osmosis membranes results in top-of-the-line performance rates for removing chlorine, hardness, heavy metals, toxins, and a long list of other water impurities. The system also features a built in booster pump and pressure gauge. A booster pump takes the incoming water pressure and brings it up to the optimal level for the reverse osmosis process. This not only increases the system's production rate, but it also maximizes the efficiency in terms of drain to pure water ratio. By monitoring a drop in pressure on the gauge, you can determine when the system's pre filters are due for a change. Compared to the industry standard 10" filters, the RCB3P's 20" oversized pre filters have the capacity to trap twice as many contaminants. This allows the system to be used heavily in commercial environments without needing to change the filters as frequently.


The iSpring RCB3P is a high capacity reverse osmosis water filtration system that removes up to 99% of over 1,000 contaminants and hardness, including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, asbestos, calcium, sodium and more. The system has a freestanding stainless steel frame and metal hanging bracket that makes installation and filter changes easier while adding a protective buffer for your system. Super-efficient RO membranes combine to provide up to 300 gallons of purified reverse osmosis water daily. The built in booster pump increases the production of purified water by raising the water pressure. The system is compatible with 11 or 20 gallon iSpring storage tank (tank not included). The iSpring RCB3P is great for light commercial use in restaurants, salons, labs, and offices all benefit in their own ways from high quality RO water.


Overall, user sentiment is positive, with 76% of reviewers giving the product a five-star rating. However, 5% of reviewers give it a one-star rating, so there is some room for improvement.


According to user reviews, the iSpring RCB3P is an excellent reverse osmosis filtration system that provides clean, fresh-tasting water for residential and light commercial usage. It is easy to install and operate, and has a compact design that takes up little counter space. The unit comes with a booster pump and pressure gauge for increased performance, and can remove up to 99% of contaminants from water, including lead, chlorine, and fluoride.
