The APEC Top Tier 5-Stage Reverse Osmosis system delivers on it's most important function - clean, good tasting water, and it does it at great value. This is a six month review. This 5-stage system includes 1 pre-filter, 2 particulate filters, and 2 micro filters. This gives it large capacity for cleaning silty water, while providing a

"You have one on every floor?" Yes. I have three APEC RO filters, and I love them all. Let me explain:

Where I live, we have "city water", but that's really a community well. The water here is EXTREMELY hard. The last time I had it tested to size out a water softener, I was hovering around 30 grains per gallon (that's about

Purchased this from the Amazon Warehouse, so it was a very good deal for a solid system. I installed the components in cheap plastic tubs (with an alarm), in case of leaks. After 3 years of continuous use everything is dry, and that includes annual filter changes and the addition of an Aquatec ERP-500 Permeate Pump. I only wish I had

I learned about reverse osmosis water from a girlfriend who later dumped me. She’s gone, but I still have the RO water. I win.

Although I knocked some stars off for the installation being complicated, that’s really not fair because I didn’t install it. I had a plumber put it in. But I saw enough to know that there is no

I am a 60+ year old female, with an arthritic right hand in a 1931 bungalow home. Anyone who owns an old home knows there will always be the unexpected lurking when working on the house - so I went into this project anticipating a few hiccups. Since I was going to be working in the kitchen, I decided it would be a good time to put in a

So far so good but I tested the PH in the filtered water and it showed 5!!! Not what I was expecting. I ordered this system because it supossedly adds minerals back into the water. Has anyone else have the same issue and how was it resolved? thank you.
Update: Almost 2 months later and the PH is still at 5, a bright orange color

Dislikes:

1) The package was kind of heavy. I had to grunt a bit when picking it up. (Hey, I had to find SOMETHING!)

But I'm pretty critical, so I'll update this review if I find any more gripes. I guess I should include I almost wet my pants when I heard a loud snap when installing the RO membrane cartridge in

It all went together exactly like the installation directions, which were clear and easy to understand. My wife is a picky water drinker and her choice of water is Nestle's pure life. She dislikes some of the more expensive cliche' waters so I had some reservations about purchasing a system only to have her not like it, but for the price

We love this filter system because it was easy to install, it's invisible under the sink, and it filters the chlorine taste out of our water. We've bought new filters for it many times in the three years that we've had it. The one disappointing thing about it is that the flow rate falls off pretty quickly with time. We're in San

I have wanted an RO system for awhile and this seemed the best for a reasonable price. Great water filtration, very fast faucet flow, great water conservation for RO, and easy to install.

I should start out saying that I am very picky about my water. I purchased a home a few years ago and had been using a Brita filter just to get by. It was OK. Much better than tap.

I'm rating this 5 stars because the unit is as good as you could get for the money. Granted, for more money you could have more expensive fittings, etc, but they are really not necessary unless you are going to be constantly moving and reassembling.

This is a best quality system. I order 2 system from them in one moth. One of them has problem with the tank, the support team call me 2 hours after I was send the email, and the replace tank came three days after. Excellent tech support, and good price. Extra filters will save for another year. Fast delivery, Very easy installation.

This has been a no-problem filter. Once you get the system installed, it's a piece of cake to do filter changes. Just remember to turn off the water first! The RC-EZ-3 filter will also fit this housing, and costs less, but it does not offer the performance of the EZ-4. I've been sticking with this model. Very happy with performance.

We bought this system back in 2013, after a Kenmore system we had for only a few years became too expensive to use anymore. We paid way more for the Kenmore system, so I thought this one was too good to be true. But, we tried it out. It has been AMAZING!

After watching a youtube video and scanning the instructions, I tackled the under-sink install.

Let's start right in on the existing negative reviews. First, the majority complain this filter does not reduce Total Dissolved Solids. That is in fact correct. It is NOT designed to reduce TDS.

The nice thing about a Whirlpool filter is, it handles sediment very well. However, as they age, you'll need to replace your filters regularly. This is easiest when you always have a filter on-hand; buying these in a two-pack ensures you always have one when it's time to change your filter. It's quite simple: each time you use the last

I have used one of theses filters for several months before ordering replacements. I was able to rinse it out and keep using it as it got clogged up. My water is laden with silt, iron and lime and the filter does a good job cleaning it up. It starts leaking when it's clogged up. Then you can either replace it or rinse and reuse it.

The unit is quite stylish, perhaps too stylish to be hidden under the sink. The compact nature of the unit makes for reducing space needed to install. Mostly uses vertical space, the horizontal footprint is quite small for what it does.

First off, I live in an area with very poor water quality. The water is poor in terms of hardness and overall TDS. These are the two primary attributes that affect taste and can easily be measured.
