APEC Water Systems FILTER-SET-CTOP APEC Water Countertop Reverse Osmosis Replacement Filter Set

A little unintuitive, if you're new to RO. Produces excellent water, though we measured and found we needed to put the RO water through an ionizer to meet our expectations. We have it located in a utility room sink, so it's out of the kitchen, which is perfect--nothing on the counter--then we put the water in the crock we had bought for the bottled water we no longer need. It handled the increase in TDS that has come with the California drought with no problems.

I have owned two APEC countertop systems replacing the filters on several occasions. The quality of the water is very good and changing the filters is pretty simple (instructions included). A few previous buyers wrote reviews recommending running water thru the #1 & #2 (carbon) filters before hooking them up to the final filters, #3 & #4.I tried this today with the replacement filters I just received and believe this is a great idea that probably will increase the efficiency and longevity of the system. It took a few minutes and flushed out a surprising amount of black sediment. After it ran clear I hooked it up and was good to go.Our household water is potable but when it comes to water for drinking, coffee, and ice this system provides a crystal clear product. We fill two 1 gallon containers as needed. It takes about 20 minutes to make a gallon.

Maybe the price is a bit higher. Overall good.

I've been ordering these for years without problems but I am downvoting to warn of a new problem:The plastic output line tube included with my latest order (October 2024) came with a disgusting, acidic, acrid plastic smell to it resembling that of a Sharpie marker. It infused the smell into the output water itself. It did not smell safe to drink. I realized that it was the output tube, not the filters, when I sniffed the outside of the tube and noticed the tube itself smelled the same. My old output line has always smelled perfectly fine, so I swapped back to it.So, SAVE YOUR OLD OUTPUT TUBE.I am calling APEC to warn them that something may have gone wrong with their manufacturing.

I own the APEC countertop filter. It was about time that I needed to replace these two filters. It was really easy to swap out the old filters with new ones. I was a bit worried about replacing them, but I love it how SIMPLE it was for me to install these. After running it for a bit until the water was clear, it measured at 8-10 PPM. I personally did not have any change in slower drip as other review mentioned.

What you are not told is how to make sure you rinse the new filters before installing. If you do not, you will push all the charcoal dust into the system, making the filter less efficient, and greatly slowing the flow of water through the system. When you get the new charcoal filter, disconnect the line in from the first line of defense, the sediment filter. Look at the new filter, and find the arrow that shows direction of water. Connect the line in from the faucet to the inlet side of the new charcoal filter. Point the outlet for that filter into the sink, and run the water for at least one minute. You will see why as soon as you turn on the water, as what comes out will be black. Run until the water is clear, probably at least one gallon. Then connect everything and you are ready to go.

Before I purchase these replacement filters. My waste water drain is not a flow smoothly anymore, and the filtered water flows slower that when I first purchased it. The installation process is super easy, I was able to complete it within 10 min, then you need to let it run for 15 mins. Afterward, the improvement is very noticeable, the waste water now flow very smoothly, and the filtered water come out much faster. You definitely need to replace your filter every 6 month. Go my fellow hydrohomies!

I really like this water filtration system. Water tastes so much better after filtration and it brings the particular matter to almost zero.
