What Customers Are Saying

The water filtration system provides great-tasting, clean drinking water with significantly reduced total dissolved solids compared to previous systems or tap water. Many users report the system is easy to install and produces increased water volume and pressure, allowing for faster filling of containers and better performance with ice makers. While some noted a slight noise from the pump, most found it to be minimal and not disruptive. The system is also appreciated for its ability to work well with low water pressure environments.

No Bottle Water Needed

Would Recommend

I have a well but where I live, even with city water, there is a non toxic bacteria that at times gives the water an odor, especially when it's heated. It goes away after a bit when it "breathes" but the taste of my coffee just wasn't good. I put a reverse osmosis system in my house several years ago and now everybody raves about the quality of my water. When my daughter moved into her new (to her) house I wanted a system for her for the same reason. And as expected, the water now tastes good. B...

My new RO system

I had an APEC RO system in my previous home and was pleased with it. I just moved to a rural area with my own well. I was so glad APEC made a system that would work for my new home.

Used to be a fan

I had previously written a review of my 12 year old product. Well, we had a failed water pressure regulator and apparently one of the tubes ruptured causing a flood. I'm not blaming APEC at all. I purchased a new system and upgraded to the stainless steel UV kit. It came pre-installed so I was all set, right? Wrong. The UV kit had an improperly installed o-ring and developed a leak after about 4 months. It came suddenly without warning. It ended up causing severe damage to our wood floors, whic...

Very pleased...

...with my new kitchen under-sink reverse osmosis system. I purchased it to replace the similar system that I paid someone to install 20 years ago. I installed it myself this time, and I'm so glad I opted for the higher flow-rate option. Everything arrived quickly in one big box.

Great reverse osmosis

I have been installed this type of reserve osmosis in my NY home for more than 12 years without any problems. I left it when when I moved to NJ. I bought the same system. It is working for 4 years efficiently. I recommended this product.
