If you want pure and great-tasting H2O everywhere you go the APEC RO-CTOP reverse osmosis drinking water system might be just what you are looking for.
The portable countertop unit is compatible with most standard faucets – pull-out, sprayer and special designer faucets won’t work – and makes use of a 4-stage filtration process to reduce up to 99% of arsenic, chromium-3 and 6, copper, fluoride, lead and dozens of other potential water contaminants.
Required water pressure: 35 to 90 psi, although below 40 psi an additional pump is recommended.
Max TDS: 2000 ppm
For better looks, the RO-CTOP is available with an aluminum case which makes a lot of sense considering that it will sit on your countertop all day.
The main reason for buying a countertop RO system instead of a regular under sink unit is that no installation is required. You just plug & play, or drink we should say.
This makes the RO-CTOP great for renters that can’t make any permanent changes to the plumbing system or where there is not enough space for a large holding tank.
But like we said, keep in mind that although the system comes with adapters it only works with standard faucets with a removable aerator.
We also like that the RO-CTOP is compact and lightweight (about 7 lbs) for high portability. Do you like to travel?
Other than that, the system uses long lasting filters Made in USA and comes with a 1-year limited manufacturer warranty.
The APEC RO-CTOP literally hooks up in minutes.
All you have to do then is flush the membrane and filters for 10-15 minutes before first use and you are good to go.
Quick connect fittings allow for fast filter changes. Here is how:
Tip: Replace one filter at a time to avoid mix-ups.
How often do filters need to be replaced?
By the way, filters and membrane have the industry standard size of 10”, meaning that they can be replaced by cheaper off-brand models if need be.
About Membrane Replacements
The safest method to determine the condition of an RO membrane is by measuring output water TDS a.k.a. total dissolved solids (using a TDS meter).
If the permeate reads 3 to 10 percent of the feed water TDS, the membrane is working well. As soon as the TDS creeps up to more than 15% replacement is due.

Our main issue with the APEC RO-CTOP is that the tubing to and from the filters/system is prone to leaking. For some users it simply cracked after weeks of use, while for others it burst open or blew off. An easy fix is to visit your local hardware store and buy a suitable replacement.
Above that, the system is a bit too pricey for our liking, especially considering that it was only certified against NSF standard 42 and that’s it.
Lastly, before buying this product you should remember that the filtration is not the fastest. Reverse osmosis purification is very thorough and takes time especially with lower feed water pressure.
If money is not an issue we see no reason not to invest your money in the APEC RO-CTOP portable countertop reverse osmosis system. It’s easy to install and maintain, it’s great for on the go and small apartments, and it provides highly pure water – the majority of users compliment the pristine taste. 5 stars!
