APEC WATERSystems Ultimate RO-Hi Top Tier Supreme Certified High Output Fast Flow Ultra Safe Reverse Osmosis Drinking Water Filter System

Working like a Champ for 7 months now, Great tasting water and easy to Install. Used some Nicer fittings from John Guest for piece of mind and T Split for Ice maker. Faucet works and we get clean great tasting water. Had Issue with first system and had to return to Amazon as Company does not warranty Amazon Warehouse (OpenBox) items.

Excellent water flow and taste of water

Very happy with it😊 it’s worth the money!

I received this reverse osmosis system about three months ago and it was a pretty simple install. I was able to complete it in over one day and over the next few days I was able to tweak the system just how I liked it. During this time I was able to run the system to the countertop faucet that's included as well as routing to the fridge as a separate line. The quality of water from what I went from is pretty amazing. I went from around 150 parts per million to a consistent one to seven parts per million even after sitting for a few days. I would buy this product again in a heartbeat.

Overall, I am very pleased with this system. After flushing 3 times, it reduced the reading on our TDS meter from 58 PPM to 1 PPM. I also noticed an improvement in taste compared to the refrigerator filter. It seems that there may be a very subtle difference in water texture...perhaps a little more slippery, but I haven't identified the exact difference.The engineers for Hydroviv actually recommended APEC as a preferred system, even though they are considered competitors.Customer service was excellent and timely.The speed of the flow was worth the extra cost to us. The flow rate is definitely faster than the refrigerator. It will make using filtered water for cooking a breeze. I have used reverse osmosis systems that seem to take forever to fill a cup of water. That is not the case at all with this system.Installation was not easy, but it is manageable if you have someone in the household with maintenance experience. The manual was OK, but could use some improvement (with concise wording in some sections, more detail in other sections, and improved grammar and wording for clarity). The color picture that showed an overview of the entire setup was very helpful. A hole needs to be drilled in a pipe under the sink for drainage in an ideal spot to prevent noise. Also, there would need to be a hole in the counter top or sink for the faucet. We had an existing hole with a diameter of 1.5 inches, which just barely worked for the faucet. Anything larger would not have worked without some sort of creative adapter and a larger washer to reduce the hole diameter. We also made the mistake of not tightening the filters enough (the manual said not to overtighten). This made a mess on the first trial. I cannot comment on ease of filter change yet since we are not due for one. Under a cabinet, it definitely seems like a tray would be needed to collect spilled water if it is mounted. Otherwise, in our case, there is enough give in the tubing to pull the system out for a filter change.The cost of filter changes at this time would be $40.95 to $52 annually for stages 1, 2, and 3. Water with high sediment may need to be changed more frequently. I was told that noticing the water flow slow down and seeing buildup in the filter would indicate a need for a filter change to prevent damage to the RO membrane. These are sediment and carbon block filters.Stage 4 replacement is $78.95 to $98.95 every 3 to 5 years. I was told that using a TDS meter to see if the water quality has changed would indicate a need for this filter change. This is the actual RO membrane that makes the system work by filtering larger particles than the tiny holes in the membrane. Stage 5 replacement is $20.95 to $26.99 every 3 to 5 years. This filter improves taste and reduces chlorine. Well water would need more frequent changes (2 to 4 years?) if the sediments are higher.Overall, I am extremely happy with this system so far. I hope this is helpful.

I have purchased and installed two of these RO-HI systems now.GOOD:I chose APEC because they also sell commercial systems, which makes them seem more knowledgeable and trustworthy than the many, many scammy RO companies that just rebrand systems and exaggerate the necessity for RO.APEC claims, though without giving any supporting evidence, that their RO membrane only needs to be replaced every 3-5 years, where all other RO companies say 1-2 years. This should save money in the long term. I wish they shared some details explaining why their schedule is somehow different than everyone else's.The faucet is really nice (but only has a 1/4" inlet).BAD:The 3 filter housings arrived dirty, like the factory worker had just finished mulching their garden and put their dirty hands inside the housings, leaving small and large pieces of dirt and stuff in them. Definitely not sterile nor sanitary. The filters themselves came in bags, but 2 of the 3 bags had holes in them.Even though this is advertised as a 3/8" system for high flow, the faucet is the same 1/4" one that all the other RO systems come with. You'll notice the kit includes a 1/4" to 3/8" adapter for that purpose. APEC claims connecting a 3/8 tube to a 1/4" faucet still improves flow, but it's obvious to everyone that they are intentionally misleading customers and ought to be absolutely clear about that up front. Why not just include a true 3/8" faucet?Their customer support is not going to impress - I emailed them some simple questions several days ago and haven't heard back.They have partner companies that sell rebranded APEC systems under a different name. Their systems and their website are obvious duplicates. Those companies claim the usual 1-2 year RO replacement schedule, which is odd since the systems look identical and APEC claims 3-5 years.The manual repeats itself in some places, and claims the input line connection comes with metal pieces, but the pieces I actually received are plastic.PERSONAL RECOMMENDATIONS:I recommend you buy an extra 1/4" quarter-turn shut-off valve and install it on your red input tube. That lets you turn off the water much quicker than their included needle valve, which requires many turns to close.I also recommend considering adding a permeate pump, which increases the outgoing water pressure, which increases the amount of water that gets stored in the tank. It also reduces the amount of waste water produced. The main downside to the permeate pump is that it makes thump noises until the tank is full, so not ideal for a quiet environment.Buy and install the little blue locking clips to every connection. They definitely help prevent leaks, though not 100%, so I think it's pretty poor that APEC doesn't include those automatically.You should get a battery powered leak alarm, which beeps loudly when it gets wet. Put one under your RO system because there are so many connections that can pop off or leak. I've seen several leaks on my first one, including one that happened 12 months later when I replaced the filters and a random tube started squirting because the new air bubbles caused bucking in the lines.You can also get an automatic, battery-free, leak shut-off valve that goes inline on your 1/4" input tubing. When it gets wet, it slams its built-in valve closed like a mouse trap, stopping your leak before it causes more damage.
