12 best reverse osmoses

Product description

As America's favorite brand of reverse osmosis systems, and backed by iSpring’s industry-leading customer support, the RCC7AK is unequaled in quality, performance, and durability. The system consists of 6-stage, layered filtration built around precision reverse osmosis (RO) technology that removes over 1000 different kinds of contaminants in order to provide the best home drinking water filtration available. Unlike some other systems, the combination of both GAC and CTO filters in the 2nd and 3rd stages provides extra layers of protection against harmful chemicals than CTO alone. It features a 75 gallon-per-day capacity RO membrane, which is larger than most in its class and provides the capacity to economically handle the drinking water needs of even a large family.



After flowing through the initial 5 stages of the iSpring RCC7 line of Reverse Osmosis filtering products, the RCC7AK model adds another Alkaline Remineralization (AK) stage. This stage is designed to restore the natural alkalinity and mineral balance of the water. The RO process effectively generates pure water but it also removes a few helpful minerals in the process. The red mineral stone portion of the AK filter adds back healthy minerals including not just calcium, but also other beneficial minerals, like magnesium, that other systems don't. The calcite portion of the filter neutralizes the pH of the RO water. And the water tastes better too. Because RO water is so pure, some people may find it tastes unnatural. Many people prefer the more natural taste that comes from the presence of some minerals in the water. Remineralization restores just the right proportion of healthy minerals.

Designed for do-it-yourself installation by most users, the entire system fits nicely under a standard kitchen sink. Installation is straightforward and all parts necessary for installation are included. You are guided by clear, well organized written instructions, instructional videos and access to iSpring’s unparalleled technical support. The system is quiet and low maintenance with no moving parts. Replacement filters are standard sized and sold at factory direct pricing. A lead-free, solid brass faucet with brushed nickel finish is included with the system and is usually mounted on the counter as the primary source of drinking water, but output lines can also be connected to your ice maker, coffee maker, etc. The whole system is backed by a 1-year money-back guarantee, a 1-year manufacturer warranty and iSpring's unique lifetime technical support provided right here in the USA in Alpharetta Georgia. With the iSpring RCC7AK, enjoy crisp-tasting, bottled quality water, every day, right in your home.

• BENEFITS: The iSpring RCC7AK water softener includes an additional sixth stage - an Alkaline Remineralization filter which restores healthy minerals and produces a balanced alkalinity, which gives your water a more natural taste than regular 5 stage RO water filter; the RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below

Reinforced Transparent 1st Stage Housing

Provides an easy way to visually inspect the sediment filter and view the contaminants being removed from your water. With the transparent housing you will know it is time for a filter change before a problem occurs.

Finest Micron, Layered Protection

The advantage of having both 5-micron GAC & CTO filters is that loose carbon (GAC, KDF) is better at trapping large contaminants, leaving only smaller ones to the CTO carbon block filter. This allows the CTO filter and RO membrane to function at their maximum efficiency and last longer.

Leak-Free System & Online Supporting Videos

Push to connect fittings and color coordinated tubings simplify the installation process and prevent leaking. We know that high percentage of our customers prefer Do-it-yourself installation. We are investing in video production and aftermarket platform to provide our customers the resources needed to have successful installation and maintenance.

User questions & answers

Question:	How big is the system? How much space do we need in the under-sink cabinet
Answer:	tank is 15x11 and filters are 15x17 I have mine mounted on wall in garage. takes up a lot of space for under the sink
Question:	How much does a single set of stage 1-3 filters cost? Where can we purchase them
Answer:	$32.30 for one whole set or $50.00 for 2 sets.https://www.amazon.com/APEC-Water-FILTER-SET-ES-Standard-Pre-Filter/dp/B00I11HUGW/ref=sr_1_1?srs=9433327011&ie=UTF8&qid=1470691669&sr=8-1&keywords=apec+filter-set-eshttps://www.amazon.com/APEC-Water-Systems-FILTER-SET-ESX2-Replacement/dp/B00SSA7OBM/ref=sr_1_2?srs=9433327011&ie=UTF8&qid=1470691669&sr=8-2&keywords=apec+filter-set-es
Question:	Does this filter remove hormones
Answer:	The answer "ROES-50 system uses a high quality, .0001 micron Reverse Osmosis membrane and 3 carbon filters so it is designed to remove high levels of hormones and pharmaceutical drugs from water" is troublesome. Terms like "high quality" and "high levels" are arbitrary, and it's a safe bet people don't want arbitrary amounts of contaminants removed.
Question:	Hi apec, i see your offshore imitator is offering transparent 1st stage filter housings, why don't you offer one as well
Answer:	I bought the ROES-50 RO system in January 2016 and for the most part it has been great. Bought the pump to go with it as well as an auxiliary accumulator tank to use in addition to the smaller bladder tank that comes with the system so we can draw a couple of gallons of RO water at near full pressure at one go (set to 60 psi), and have the output plumbed to the sink faucet and two refrigerators with ice makers and water dispensers. I say all of this to say that I change the filters quite a bit and that it would be nice to be able to see the condition of the filters without having to shut off the supply from the house plumbing, and shut off both of the pressure tank valves as well as the system backfeed valve I installed just to get a look at the filters. I have a well and have two of the "dreaded" clear Whirlpool whole home water filter units, one at point of entry before the well bladder tank, and one after my water softener system and before my UV sterilizer, both of which have been in service for 18 years without issue. Everything is installed in my utility room on the wall for easy access, and I replace the O-rings in the filter housings about every third filter change and wash the housings out with a bleach solution, rinse them well and lubricate the O-rings with silicone grease when installing new filters every time I change a filter, and never ever tighten any of them tighter than hand tight unless there is a drip, but I can't recall there ever being one. I don't understand why people have filter housings break unless they are being over tightened, installed in a harsh environment exposed to the elements, or somewhere where they are subject to being hit with things and getting damaged physically, or in direct sunlight and subjected to UV radiation. Therefore I wish there was an option to purchase clear housings for the ROES-50 filters in order to make proper maintenance as easy as the rest of my system, because other than that, the only complaint I have with the ROES-50 is that the white bladder tank that came with it leaks air and I have to repressurize it about every six months. The larger blue auxiliary tank I bought has yet to need to be repressurized.

User questions & answers

Question:	How much water does the system use to flush all the contaminants. My present system uses 3/4 of a gallon to produce 1 gallon of clean water
Answer:	well you could filter salt water with it, but it still wouldn't be potable to humans =)
Question:	Is it possible to add uv light to this system? how much would it cost
Answer:	You'll have to go on the data sheet from the manufacturer on the filter fiber diameter since no consumer can reasonably measure the filter tube diameters. And you'll have to do research on bad virus sizes to determine if those viruses will be blocked. But I'll say as a consumer of this filter over twelve days on the trail, serving 4 people (48 people-days) on the AT, no gastro-issues. And the filtering flow rate is amazingly fast.
Question:	Does this system come with a faucet or must that be ordered additionally
Answer:	Everything that you see illustrated. There are two reservoirs, the filter and the hose. The only thing not included is the optional carbon filter which isn't neccessary. If you do opt to purchase the carbon filter, keep in mind that it slows down the filtration time drastically.
Question:	how much room does it take up under the counter
Answer:	No, but it is surprisingly very long compared to others that I have seen.

User questions & answers

Question:	Does it require professional installation? I have no idea what goes on under my sink
Answer:	The system is packaged with the idea of do it yourself so you don't have to get professional help. Many of our customers were able to install it themselves by following the very comprehensive installation manual that we include in the package. We even have a video on youtube that shows how to install our system step by step. However, if you are not comfortable installing the system, any local plumber should have no trouble installing it for you in an hour or so at most.
Question:	Can I hook it up to the ice maker on my fridge and use the included water faucet
Answer:	Our system can be hooked up to the ice-maker on the fridge with proper connections. It can either be tee off so that it sends water to both the included faucet and the ice-maker or to the ice-maker or our included faucet by itself.
Question:	How often do the filters need replacing and what is the cost
Answer:	I use a 1-3-5 year schedule and my filter works as well now as the day I installed it: * Every year I replace the first three stages or the large vertical filters @$30-$50 if purchased separately * Every three years I replace the fifth stage filter, horizontal filter on the top @$20-$30 if purchased separately * Every five years I replace the fourth stage reverse osmosis filter @$30-$40 if purchased separately You can usually get a discount and get all five stages for @$125-$135. If you try to save money and not replace your filters as scheduled, you will probably foul up the stages behind it even faster. For example, if you try to save money by not replacing the first three filter stages you will end up having to replace stages four and five way more often. Which is actually a more expensive scenario. I hope this helps you make a smart purchase or helps with your maintenance!
Question:	It says in the description that the unit removes flouride. Has anyone had a chance to measure the flouride levels in their water after filtering
Answer:	The System is tested under the Water Quality Association to remove fluoride at 97.7% and the membrane itself was tested by the manufacturer Dow Filmtec to remove at a range of 90 to 97%

We rely on clean water to remain healthy and hydrated, and water filtration systems provide peace of mind to homeowners so they can trust the water coming out of their faucet.

Space-Saving Design

It’s time to take back your kitchen. The area under your sink is a useful place to store household items, and our under sink filtration system’s small footprint allows you more storage options than any other under sink filtration unit available.

UltraEase Filters: Insert. Twist. That's It.

The UltraEase Filter Replacement requires a simple quarter turn of the wrist to release the old filter and replace it with a new one. You never have to touch a dirty filter or turn off your water supply, so changing your filter is a breeze.

6-Month Filter Life

Most water filters need to be changed every 2-3 months. Our systems are an entirely different story. The EZ-Change Indicator Light will let you know when it's time to change filters, so you always have the cleanest water available.

Why should you choose Waterdrop G2 P600 Reverse Osmosis Water Filtration System?

The G2 P600 RO system has superior filtration. Two composite filters reduce most contaminants.

With a fast and stable water flow rate of 600 GPD, this system will fill a cup with water in 8 seconds.

The G2 P600 reverse osmosis system produces less waste water, dispensing 2 cups of pure water will produce only 1 cup of waste water.

This smart RO system has filter life indicators, which will remind you to replace the filter in time, so that your water stays fresh.

Why do you need a reverse osmosis system?

Your drinking water may be contaminated by an unclean water source or tap water. Drinking unclean water for a long time will affect your skin, digestive system, teeth, nervous system, etc.

The RO membrane has a pore diameter of 0.0001 μm, which does not allow large molecules or ions to pass through. Therefore, it reduces most contaminants in water.

*An electrical outlet is required to operate the RO system.

*If you are using well water, we recommend applying a pre-filter (5-10 μm).

*Placing this RO after a salt-based water softener may affect the taste (reduction rate 90%).

*We do not recommend connecting tankless RO to a refrigerator or ice maker.

Most contaminant reduction

Composite filters can reduce most contaminants in water, such as TDS, salt, nitrates, PFAS, fluoride, and heavy metals. The G2 P600 RO system delivers more effective filtration. Every sip is a burst of pure freshness.

600 GPD fast and stable water flow rate

You will get a cup of water in 8 seconds, which is 12x more efficient than traditional reverse osmosis systems.

2:1 low drain ratio

Dispensing 2 cups of pure water will produce only 1 cup of waste water. Compared to traditional RO water purifiers with a water tank, the G2 P600 reverse osmosis system saves 600% more water.

Premium faucet

This RO system also comes with a lead-free brushed nickel faucet. If there is no hole in your kitchen sink or countertop, you have to drill a hole or use the hole for the soap dispenser.

User questions & answers

Question:	Height required for installation
Answer:	Hello Coco LeRoux,As James M Groen previously commented, we would not recommended using a UV filter alone without another form of filtration preceding it since microorganisms can be shielded by other water contaminants. Kindest Regards,Alicia iSpring Water Systems | (678) 261-7611 M-F 9-5 EST
Question:	Does it make sence to upgrade this system with deionization filter when it has alkaline filter
Answer:	Smart Flow Sensor Switch powers on/off UV light automatically by water flow, so it must be installed after the storage tank where water flow is high enough, if you install it before the storage tank the water flow will be to slow for the Sensor Switch to turn the light on.
Question:	Is there an indicator that tells you when the filters need replacing, or do you guess ~6 months for uv light and the ph cartridge & 12 for membrane
Answer:	TWS is more powerful than ows. 55w compare to 40W. We normally suggest our customer install the OWS unit horizontally. Cause vertically installation might need extra support if the pipe is plastic. But that was not a problem for TWS system.
Question:	how many gallons of water is wasted to make 1 gallon of filtered water
Answer:	As long as you protect it from freezing, it has to be plugged in, we have it installed inside. We are on a well, have a sediment filter, a carbon filter then the UV water purifier installed in the same line. Going to get a test kit and test the water for bacteria and see how well it does.
