Customer Review Analysis

We analyzed various e-commerce websites and online forums to try and understand what customers think of the APEC Portable Counter Top RO system.

Buyers have given very high ratings on their reviews and seem more than happy with their purchase. They have complimented the flavor of water, ease of installation, and think it’s great value for money.

It takes just a few seconds to set it up and can be done by anyone. The compact design and aluminum case make it look stylish on your kitchen counter.

The four staged filtration process does a rigorous job in cleaning so the output is pure, crisp, drinkable water. When bought with an additional calcium carbonate filter, the purified water has a better taste and is healthier.

One tiny problem with the design is the absence of a storage tank.

So if your feed water has a low output pressure, it will take ages to fill a jar every time you need it. But there’s absolutely no issue if the feed water pressure is good enough.

Overall, for such a pocket-friendly price tag, this RO water filter is a great buy.
