    Can this unit be installed outside I live in Florida and there's not a lot of room to put this anywhere else

    Answer This Question

    Hello Valued Customer. According to APEC’s installation guidelines, whole‑house filtration systems such as the CB3‑SED‑KDF‑CAB20‑BB should be installed in a location that is protected from direct sunlight, excessive heat, freezing temperatures, and weather exposure. While the system may be placed outdoors, it must be installed in a sheltered area—such as under a covered patio, inside a weather‑proof enclosure, or within another protective structure—to prevent UV damage, housing degradation, and performance issues. Best Regards, APEC Customer Support

    By|Apr 15, 2026

      Hello, Thank you for reaching out. This unit is designed for indoor installation or in a sheltered location. It is not recommended to install the system outdoors, even in Florida, as exposure to direct sunlight, rain, and temperature extremes can damage the housings and components, and may void the warranty. If space is limited, we suggest considering installation in a garage, utility room, or within a protective enclosure that shields the system from the elements while still allowing proper ventilation and access for maintenance. Best regards, Aisle A. APEC Customer Service

        DOES THIS FILTER CONTROL MANGANESE
        ByOct 12, 2024

        Answer This Question

        Dear Mike, This is a very high quality filter setup designed for sediment, chlorine and chemicals. and general heavy metals reduction. However, if manganese levels are moderate to higher than normal or if water quality is unique, it is recommended to install a backwashing heavy duty tank systems like our Iron-Hydro system below for manganese, iron, and hydrogen sulfide removal. https://www.homedepot.com/p/APEC-Water-Systems-APEC-Water-IRON-HYDRO-15-FG-Whole-House-Water-Filter-System-For-Hydrogen-Sulfide-and-Manganese-IRON-HYDRO-15-FG/326656218 Best Regards, Ken APEC Customer Service

            Does this system remove uranium?
            BySep 23, 2022
            1 Answer | 
            Answer This Question

            This system does not remove uranium from the water. You would need an under sink reverse osmosis drinking water system to remove Uranium.

                Why is the flow rate for this system so low? Other systems of this type put out 12-15 gallons per minute. This one is rated at 1.6 gallons. Please explain that to me. Thanks.
                ByFeb 8, 2020

                Answer This Question

                Hello, from the manufacturer, the best level of filtration will happen at a flow rate of 1.6 gallons per minute. If you were to go over that rate, it wouldn't lower your water pressure in the home, but it wouldn't filter as effectively. The more contact time with the filter, the better removal of the contaminants. If you need further assistance, feel free to contact us directly by calling 1-800-880-4808 or e-mailing us at info@apecwater.com. We are in the office from Monday-Friday from 8:00am-5:30pm PST.

                  Great whole house combo
                  Just had this installed along with a pre-sediment spin down and a bypass system. I also encourage you to include a bypass system and a pre-sediment filter. We are on a community well and the water has some sediment and scale. I love how easy this is to maintain and tweak the different filters with what ever filters I would like to suit our needs from our well. Highly recommend this!

                    Had to have a plumber install it, but for our needs it was worth it.

                      This seems to be working
                      This seems to be working well. I was surprised at the a tent of costs for the plumbing fixtures and pressure gauges. This was a substantial increase in the overall costs for installing my system

                        Good enough with out the salt issues systems
                        So far so good, The system works well, water tastes good. Wonder how long the water has to run to clean the new filters? And I also wonder if anyone here knows if softness hard water a little. Some?
                        by
                          The water filter is working well. There is no chlorine smell any more in the water. The water pressure in the whole house also seem to be pretty good.
