Questions & Answers

What part of the product are you picking a color for

Answer This Question

Hello, Thank you for your question. The color option previously referred to the faucet finish included with the ROES-50 system. We have since standardized this model, and the ROES-50 now comes with a brushed nickel faucet as the default option, so there is no longer a color selection available. The brushed nickel finish offers a clean, modern look that complements most kitchen styles and décor. Best regards, Aisle A. APEC Customer Service

      I have a private well with low water pressure. What do I need to change arsenic 3 to 5? Also need a sediment filter if this doesn't have one. Thanks!
      BySep 22, 2026
      1 Answer | 
      Answer This Question

      Dear valued customer, The ROES-50 includes a sediment filter, two carbon pre-filters, an RO membrane, and a polishing carbon filter. While RO systems are generally effective at reducing arsenic, the performance can vary depending on whether arsenic is present as As III or As V. Because oxidation methods and treatment recommendations depend on your specific well water chemistry, we recommend consulting a local water treatment professional familiar with your water test results for the best solution. Best regards, Apec Customer Support

        Does this system then return minerals into the water
        BySep 16, 2026
        1 Answer | 
        Answer This Question

        Hello, Thank you for your inquiry. The ROES-50 does not include a remineralization filter, so it does not add mineral back into the water after the reverse osmosis filtration process. If you are looking for a system that adds mineral back into the purified water, the ROES-PH75 includes a remineralization stage designed for that purpose. If you prefer the ROES-50, you can still add a remineralization filter as an upgrade to achieve a similar effect. If you would like assistance selecting or installing a remineralization filter, please feel free to contact us directly at 800-880-4808, Monday through Friday, 8:00 AM to 5:00 PM Pacific Time. Our team will be happy to provide guidance and assist you with the installation. Best regards, Aisle A. APEC Customer Service

            Does this system clean itself by running water through itself when not used for a certain amount of time, and does it clean itself after every use? if so how often and how much water it uses?

            Answer This Question

            Dear valued customer, The APEC ROES-50 does not have an automatic self-cleaning or automatic membrane flush feature. It is a traditional tank-style reverse osmosis system that operates only when water is being produced and when the storage tank needs refilling, Best regards, Apec Customer Support

              Dear valued customer, We recommend that the pre filters be replaced on average every 6 to 12 months and the stages 4 and 5 to be replaced on average every 2 to 4 years all depending on water quality and usage. Best regards, Apec customer service

                I want to change the faucet to an oil rubbed bronze faucet. There are many aftermarket choices, but I'm worried about compatability. What do I need to change the faucet, just a different faucet, or a new faucet with certain hoses and clips I'll need?
                ByAug 9, 2026

                Answer This Question

                Hello, Thank you for your inquiry. You may use a faucet of your choice. We recommend verifying that the faucet is compatible with a reverse osmosis (RO) system and is lead-free before installation. Depending on the RO system you purchase, the outlet connection will typically require either 1/4-inch or 3/8-inch tubing, so please ensure the faucet you select matches the appropriate connection size.

                  Will leak in 2 years
                  Add us to all the other leaks being reported. Same exact thing, 27 months in, the housing cracked causing a leak. Contacted APEC, they say you need to replace the cracked part for $28 but it’s out of stock for at least 2 weeks and if you add filters to get over $50, you get free shipping! Gee nothing better than an upsell on an obviously defective design that you can’t even fix for weeks. We said no thanks and promptly purchased a new system from Home Master. Still made in the USA but offers a 5 year warranty. We won’t buy APEC again, far too many people having the exact same leak around the same time frame.

                    Cracked housing cap defect
                    This will only last about 2 years. The housing caps develop hairline cracks quite easily which cause leaking issues. Mine developed cracks on both slides of the inside housing capes on ALL 3 CAPS. This caused massive leaking issues every few months. Finally got in contact with customer service for APEC that said this was a rare issue but after seeing insane amounts of reviews with the same issue it doesn't seem so rare. The part was $35 for them to send new housing caps. Then $19 for shipping which is crazy. I wouldn't recommend. Water tastes good but all the leaking issues I've had i wouldn't suggest this unit.

                      Another Victim of Leaking
                      Add me to the long list of victims of leaking cracked housings that have had their cabinets saturated with water. I was lucky to have opened the cabinet door and discovered the leakage before it permanently warped the floor and sides. It stained the wood and began developing mold. ALL 3 HOUSINGS HAVE CRACKS ON BOTH SIDES! Pics included with this review. I can only guess that the worst one was the worst leak. Too jagged and inconsistent to be seams. These are all at points that could not have been caused by the homeowners. Water pressure has been regulated, so not an excuse. Leak detection is a priority from now on. I'm sure that this will be replied to with the general AI response(s) that others have been.

                        2.5 years in and all 3 filter heads are cracked
                        We purchased this system in 2023 and it does a great job at cleaning the water. However, when replacing the filters I noticed all 3 plastic filter heads were cracked. This is not covered under warranty at this point even though it’s under 3 years old and there is a cost to replace. I am modifying this system to use Stainless Steel housings to replace the 3 plastic ones that are provided. I was really hoping that this system would last longer than 3 years. Just be aware that if you buy this, it’s highly possible you will need to check the housings carefully at each filter change to make sure they are not cracking. A flood in my friends kitchen happened when they were away for the weekend. $40K in damage and a lot of personal items lost. I can’t risk it with this system so I’m building my own.

                          Watch out for leaks down the road!
                          It was great until it wasn't! After one year the upper filter housing on #1 filter spontaneously just cracked internally. It leaked water all over my kitchen. I had to buy a new filter housing & completely disassemble the whole filter assembly to replace. It was not a fun job at all. Terrible quality of the filter housing.

                            Not great.
                            Bought and installed this unit (APEC ROES-50) 2 yrs ago. So far it’s been great. It just started leaking though out of nowhere… upon taking it apart I found the filter housings are cracked on the inside where the fittings link each filter housing together!!! So now I will have to replace the whole unit.

                              I had a previous 3 stage RO system that was 21+ yrs old and needed to be replaced when I remodeled my kitchen! Super easy install, including adding a Tee fitting for the fridge/freezer from HD! I’ve only had the system for a little over a week but the family loves the water and saves me $$$ and the environment not buying plastic bottles! Zero leaks so far! I recommend this system 💯

                                I have a old RCC7 system since 2013 and recently it got leaking from the filter housing cap. After I called Ispring support, Sean was so nice that he sent brand new system (without the tank) to my house. Now the whole system is working again. I strong recommend this RO filter system from ISPRING. I really appreciate Sean help! Mark
