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

"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

A lot of good descriptive reviews here, I'll add mine here but will focus on my perspective as someone living in Israel.

Israel is an arid country which in recent years made a big transition to desalination. The national water company (called "Mekorot") is using >50% desalinated water from the Mediterranean Sea

We have a well in our new house that has elevated arsenic (0.020) and radon (15,700). The radon is really high, the arsenic is twice the acceptable limit.

We installed this unit and had a arsenic and radon test done after the install. Our arsenic went from 0.020 to 0.0001. Well less than the 0.010 acceptable limit. Most

Just installed so this is based on first impressions. Will update with longer term review.

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.

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

Best filters ever, this is a high technology product and well worth the cost, when you compare side by side a used Filtrete and a new one you can see the difference (and health wise not breathing all that contamination captured by the Filtrete).

While I do like Filtrite filters, the "smart" filter is anything but. The app reports they need replaced whether they do or not. They only track time not use or airflow. There's no way to reset a filter that doesn't need changed. The MAC is permanently linked to your account, so you can't even delete and re-add it. The circuit doesn't

No way this 2-pk is the same genuine Filtrete MPR 2200 I bought at Lowes. It is flimsy and the gauze material has visible holes in the medium. Additionally, there are so many discrepancies in packaging, product, and even the copy on the filter. The genuine Filtrete uses "TM" and the fake came with a registered mark.

Unfortunately, these filters restricted airflow. I read several articles on best air filters, most stated getting filters with high MERV ratings.

I had hoped to find a quality filter at less than 3M pricing...Nordic Pure is not it.

They really market their MERV ratings, but there is more to it than that...the filters have 1/4 (ONE QUARTER) the filter area as compared to a 3M 2200 filter. (Nordic Pure has 25 'pleats', the 3M over 100 pleats.) Why is this an issue? As

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.

Hello. I think this product is probably great, and I wouldn't review it this way if they allowed me to return it.

Don't get it confused for reverse osmosis. This won't cleanse the water. It specifies this in the instructions too. It's meant to reduce the bad stuff in tap water and improve taste.

Pros:

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. Says so right in the ad, and right on the packaging and instructions. Only Reverse Osmosis reduces TDS. Match your expectations to the product

High level package, definitely goes beyond my expectations. I feel that this is a detail oriented brand. The accessories are complete and the installation was quite simple.

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.

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.
