very good water filter system

I live in central Florida and the water here is horribly hard and tastes terrible.  I have owned this system before and was very happy with it's performance so when I built a new home I purchased the same system.  Lime deposits are virtually eliminated and the filtered water is refreshing and has little or no taste the way pure water is suppose to taste.  Installation can be easy but the manufacturer only supplys connecting hardware for one type of connection so you may have to buy hardware as I did to install it under the sink into the existing water supply.  I found all the hardware I needed at the Home Depot so it didn't take anything special.  I installed this system to city water, I can not say how it would perform with well water.

I am extremely happy with this filtering system.  I am a woman, and installed this system two weeks ago by myself.  The installation instructions were pretty good but could be a little more clearly written. The diagrams were excellent and showed exactly how everything connects together.  One reviewer suggested mounting the filter canisters on wood and attach to the cabinet with a drawer slide.  I actually bought the slide to do this, then realized it really wasn't necessary and would just take up a lot more room in an already confined space.  After installation I spent about an hour stopping leaks - all due to my not tightening things enough - most specifically the connection to the holding tank.  The most stressful aspect was cutting the hole in my brand new stainless steel sink for the faucet.  I bought a metal punch, and a brand new drill bit and had no problem.  The water pressure from the faucet is excellent, the water tastes great, and best of all, I don't have to lug water jugs to the health food store for water anymore.  It is worth having the bigger tank to get better water flow so don't skimp on this.  I highly recommend this system!

AQ-5300.56 Under Counter Water Filter System was easy to install. Connection fittings are better than other similar products that were reviewed. Instructions were adequate, although slightly vague on faucet installation. Whole system was up and running producing clean, clear, excellent tasting drinking water in less than thirty minutes. Water flow was also excellent, which was one of the primary reasons that this product was selected and purchased. Filter replacement cost is less than other comparable products. I researched other filter systems for several months before settling on this AQ product. Based on preliminary experience, I anticipate good service from this product. Unless something unexpected comes up, I would highly recommend this filter system.

This is a great RO filtration system! I did quite a bit of research before purchasing. Besides being a great system I like that the company is a small business. They have excellent customer service! I always try to shop small when I can. I highly recommend this iSpring RO system! Great tasting water will be flowing your way!

The quality of the filters and the supplied faucet looks excelent. It even included the brass fitting for the water supply line that is not always the case in comparable product. The water tastes very good now at home and it is very convenient to open the faucet and get filtered water. The water flow is ok (maybe a tad too slow), but I guess that is as good as you can get if you don't have a unit with a storage tank..Very satisfied and would recommend this to others.

These are the best filters I have used at this level, these won't filter out the cycts, and microbes that can make you sick, but it does an excellent job of making local potable water taste like a clean pure water.  I bought for work as our systems are old and piping is not great, when we fill up a gallon of water for coffee, it looks a little off yellow-clear, when that same water is run though this, its crystal clear.
Again not going to work for river/stale or unsafe non-potable water, but for cleaning your local water it's well worth the money and saves you a ton over bottled.

We have used these for years and our water is great.  Our community water is drawn from the river in the summer and can be pretty nasty but our filtering system gives us great tasting water,

I have used these filters several times. The system and filters do a great job of cleaning our water.
I reordered these filters and as always they arrived on time and work very well.

This system installed easily with the supplied fittings and has functioned perfectly over the past few months.  The twist-lock system makes replacing filters very easy.  I have not noticed a drop in pressure as a result of installing the filter.  I can't tell if it's actually doing anything (water seems to taste the same?) but then again, I can't tell the difference with Brita/PUR filters either.

I have been using this unit for about 3 years and have had no problems. The water tastes good, but don't expect it to taste as good as a reverse osmosis system, its not. This type of system is suppose to be healthier for you than the reverse osmosis system, only time will tell. Its alot cheaper to keep using and is much more compact. The facet is of good quality and the only thing you should have to do is change the filters every 6 months.

The filter was fairly easy to install.  I have had it for about 4 months now with zero issues.  The quality of the water is amazing.  I am very glad I went with this purchase as it was well worth the money.  They have a customer service line that picked up on the first ring and helped me with a few questions I had.  Highly recommend this product.

I installed this system in my original 1939 kitchen. As I live in the desert in southern Arizona, I ported the waste water out to the garden rather than down the drain, so I can't speak to how well it connects to the drain. However it does a nice job pushing the waste water through about 30 feet of 1/4 inch tubing out to my mesquite tree.

Pros:
STURDY CONSTRUCTION. Everything feels solid, not cheap China-built garbage you might get with other systems. That was really my main reason for buying this system: I wanted it to last.
VERY HELPFUL DIRECTIONS. The directions were probably the best installation manual I've ever read. I felt confident drilling a hole in my 76-year-old ceramic tile countertop with these instructions. They told me everything I needed to know. The hole worked out great. My faucet looks like a professional install.
MADE IN USA, DOMESTIC TECH SUPPORT. I did have a leak when I first installed it, but it was easily resolved by a quick call to tech support.
VERSATILITY. The filters can be hung on the side of the cabinet, as I did, or just sit on their own in the cabinet. They don't even have to be upright, so they can accommodate lots of different kitchens. Likewise, the four-gallon storage tank can sit upright or on its side. The storage tank, filter unit and faucet don't even have to be in the same cabinet. In my photos you can see I needed to put the tank in one cabinet, the filters under the sink and the faucet in that little right cabinet. No prob. Just drill a few holes and run the tubing. I've never had an RO filter before, so this may be true of all systems, I don't know.
STANDARD FILTER SIZES. They use standard sizes for filters so you don't have to buy their filters. Some other companies have special sizing such that you have to buy their replacement filters and then they gauge you on filter pricing. I will be buying their filters but it's nice to know I don't have to.

CONS:
I haven't found one yet. I have a TDS meter. It's 326 before and 27 after. I'm happy. I've only had the system six weeks but it's a great buy for the money so far!

Full disclosure: Apec has offered me some free filters to write this review. That said, everything in here is my honest opinion. I am really happy with this system, and I'm glad I didn't take my neighbor's advice and buy Costco's system, which is not nearly as solid as this one. Would I have written this review without the Apec offer? No, I'm too busy. Honestly, who has time to write Amazon reviews? But everything here is my own opinion.

I live in Santa Clarita and the water up here is horrible.  My brother recommended this water filter system and I couldn't be happier.  The water tastes so good that I bring a large container to work and drink it all day rather than using the filtered water at the office.  I am very pleased with this system.

Very easy to install.  Water tastes very good, very clear.  A great option to the expensive name brand filters.

This filter system was very easy to install. I watched the video on YouTube and that made the install painless. The instructions that come with this system are very vague and not helpful. I have well water and now with this system I can actually drink the water. No more bottled water! The price for this system is very reasonable and the replacement filters are reasonable too.

this is the easy system to keep your water fresh and pure for the whole house.  there are other brands of filters out there to purchase, over the years I have found the 3M to be the best.  I check and replace every year and I use a water softner loop so I do not treat the out side.
we are a family of 2 adults and this does last us a year, easy to install not out of sight.
Arizona in our area has very hard and mineral rich water this unit has solved our problem with out salts
