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

Extremely happy with system
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 bought two units, one for my family and the other for my daughters family. I had a GE smart water system for over 10 years and replaced it with APEC – RO-Hi Supreme system. It is working fine. It was installed few weeks ago. It is too early to rate accurately. So far working well.It is an obligation and responsibility to support a product which meets or exceed the expectations.

Long story short, it is all hooked up and it works – but it came with a broken fitting and the company’s solution is for me to take it all down, and send it back to amazon and order another one!I just found a compatible part and ordered it myself.We bought this as R.O. is the only feasible way to remove salt from water, and our well water is pretty salty (nearly 3%!).In taste tests, this water tastes better than the drinking water we’ve been buying at the store.
