Under-Sink & Countertop Filtration Reviews Archives

Reverse osmosis filtration purifies municipal tap water far beyond what city systems do. It removes all sorts of contaminants, from plastics to bacteria to toxins. Reverse osmosis systems are durable and need very little maintenance. They are easy to maintain, so you may not even need a plumber to install one for you. Let’s take a look at three of the best reverse osmosis water filters on the market to see which is the best for you.

iSpring RCC7AK 6-Stage Residential Under-Sink Reverse Osmosis Water Filter System w/ Alkaline Re-mineralization-WQA Gold Seal Certified, 75 GPD

iSpring RCC7AK

iSpring RCC7AK

What makes the iSpring RCC7AK special? Not only does it purify your drinking water, it gives it a tasty flavor. After the 5-step cleaning process is complete, it puts the water through a 6th step, a re-mineralization filter.

This alkaline filter uses the mineral calcite and red mineral stones to add calcium, magnesium, sodium, and potassium to the purified water. Your water will taste like natural spring water and have a better pH balance for your health. Normally, the reverse osmosis process makes water a little acidic, but this 6th stage filter turns it neutral.

Besides the great flavor, the RCC7AK systemgets rid of up to 99% of over a thousand pollutants. That means you won’t need to worry about drinking or preparing food with poisons like chlorine, fluoride, lead, arsenic, pesticides, viruses, bacteria, sulfur, and plastic derivatives. Unfortunately, these toxins do appear in small amounts in municipal drinking water, so it’s a really good idea to have a trustworthy filter.

iSpring has the RCC7 Water Quality Association (WQA) Gold Seal certification because their filters have passed rigorous and detailed testing. The RCC7AK passes the National Science Foundation (NSF) highest standards for reverse osmosis filters. Each part of the filter that comes in contact with the water isfood-grade certified. They even include an elegant new water faucet in the box in case your current one has a buildup of contaminants inside it.

One thing you will have to do to maintain your RCC7AK is change the individual filters of your system. The 1st stage is transparent so it’s easy to see when it’s time to swap it for a new one. iSpring says you may need to replace the first three stages of filters every three to six months.

The 4th stage is the reverse osmosis membrane, and that may need to be changed every two years. The 5th stage should last about a year, but the alkaline filter, the 6th stage, should be changed about every 3 to 6 months.

Besides linking the RCC7AK to your faucet, you can run output lines to your refrigerator’s ice maker and your coffee maker. This system can output 75 gallons per day so you and your family have plenty of clean water at home.

More features of the iSpring RCC7AK Reverse Osmosis Water Filter System:

  • iSpring offers a 1-year money-back guarantee as well as a 1-year warranty plus lifetime tech support
  • Holds up to 2.5 gallons of water ready at a time in the 3.2-gallon pressurized tank
  • Comes with lead-free European-style Brushed Nickel Faucet, complete filter pack, tubing, wrenches for installation, feed water adapter for both 1/2″ NPT & 3/8″ COMP, drain saddle, spare fittings and O rings, and user manual

 

iSpring RCC7AK-UV 7-Stage Residential Under-Sink Reverse Osmosis Water Filter System w/ Alkaline Re-mineralization Filter and UV Sterilizer – WQA Gold Seal Certified, 75 GPD

iSpring RCC7AK-UV

iSpring RCC7AK-UV

The iSpring RCC7AK-UV adds a 7th stage, an ultraviolet sterilizer, to the 6 stages present on the RCC7AK. The UV sterilizer eliminates whatever small amount of microorganisms that might still be in the water after the regular filtration process. It kills any leftover viruses, bacteria, and parasites like giardia. This is especially helpful if your water comes from a well.

The 11-watt UV light turns on and off with the water flow. This makes the UV bulb last longer and puts less strain on your electric bill. But don’t worry that adding a sterilizer makes this filter hard to install—it doesn’t. The RCC7AK-UV is just as easy to set up as the RCC7AK described above.

It comes with iSpring’s WQA Gold Seal Certified reverse osmosis filters, plus the alkaline stage that balances the pH and adds a pleasant flavor to the water you drink. It can process up to 75 gallons of water per day.

  • Holds up to 2.5 gallons of water ready at a time
  • Comes with lead-free European-style Brushed Nickel Faucet, complete filter pack, tubing, wrenches for installation, feed water adapter for both 1/2″ NPT & 3/8″ COMP, drain saddle, spare fittings and O rings, and user manual

 

iSpring RCC1UP-AK 7-Stage Residential Under-Sink Reverse Osmosis Water Filter System w/ Booster Pump, Alkaline Re-mineralization Filter, and UV Sterilizer

iSpring RCC1UP-AK

iSpring RCC1UP-AK

What sets the RCC1UP-AK apart from the other two iSpring reverse osmosis filters described above? Pressure. The RCC1UP-AK has a booster pump that raises the pressure of incoming household water so that it can be cleaned efficiently by the system. If your home has water pressure below 45psi, this may be the perfect filter for you.

Besides the booster pump and iSpring’s WQA-certified 5-stage water purification system, the RCC1UP-AK includes the 6th stage re-mineralization filter and the 7th stage UV filter. The re-mineralization from calcite and red mineral stones adds flavor and alkalinity to the purified water. The UV filter kills off any remaining parasites, bacteria, and viruses with a ultraviolet light that turns on and off with water flow.

If your home is supplied by well water, this may be the best reverse osmosis system for your household. Not only can you link it to a kitchen faucet, you can run lines to your refrigerator’s icemaker and even your coffee maker.

  • iSpring offers a 1-year money-back guarantee as well as a 1-year warranty plus lifetime tech support
  • Holds up to 2.5 gallons of water ready at a time
  • Comes with European-style Brushed Nickel Faucet, complete filter pack, tubing, wrenches for installation, feed water adapter for both 1/2″ NPT & 3/8″ COMP, drain saddle, spare fittings and O rings, and user manual

 

Recommendation

If you have low water pressure (under 45psi) from a well or municipal supply, consider getting the iSpring RCC1UP-AK. Its booster pump raises water pressure so the filter system works at top efficiency. It has a re-mineralization filter to add flavor and reduce acidity, as well as a UV filter to remove any remaining microorganisms.

If you have good water pressure and want the added security of a UV filter to eliminate any bacteria, viruses, or parasites left in the filtered water, take a look at the RCC7AK-UV. It adds minerals back into the purified water so it tastes better than regular filtered water.

If you don’t need the added protection of a UV filter, but still want pH neutral filtered water with a pleasant taste, consider purchasing the iSpring RCC7AK.

What if you could have all the pure water you could drink all day long without having to pay for bottles? Forget those pitchers and sink adapters with filters. They’re good, but there is something even better. Reverse osmosis filtration cleans tap water well beyond what municipal systems can do. It removes all sorts of contaminants that some of these smaller filters can’t. Reverse osmosis systems last for years, don’tneed much maintenance, and are easy to install by non-professionals. Let’s take a look at two of the best filters on the market to see which is the best for you.

iSpring RCC7

iSpring RCC7P

iSpring RCC7 5-Stage Residential Under Sink Reverse Osmosis Water Filter System – WQA Gold Seal Certified, 75 GPD

When you see the abbreviation “GPD,” that’s gallons per day. Imagine how many pitcher filters or bottles of spring water you’d have to buy to arrive at 75 gallons per day. Those little faucet-mounted filters can’t keep up with the iSpring RCC7.

The RCC7 eliminates up to 99% of more than one thousand pollutants. That means you won’t need to worry about drinking or preparing food with poisons like chlorine, fluoride, lead, arsenic, pesticides, viruses, bacteria, sulfur, and plastic derivatives.

If you aren’t sure if you can trust their claims, just know that iSpring has achieved the RCC7 Water Quality Association (WQA) Gold Seal certification after rigorous testing. The RCC7 passes the National Science Foundation (NSF) high standards for reverse osmosis filters. The filter’s parts are all food-grade, and the filter itself is built in the USA. They even include a new water faucet in the box in case your old one has a buildup of contaminants inside it.

You can easily keep an eye on the status of your filter because the 1st stage is transparent. That also makes it kind of pretty, so it’s too bad you’ll be installing it underneath your sink. In fact, you can set it up yourself without a plumber—it’s that easy. Besides linking it to your faucet, you can run output lines to your refrigerator’s ice maker and your coffee maker. Just check first to see if you need additional supplies.

More features of the iSpring RCC7 Reverse Osmosis Water Filter System:

  • iSpring offers a 1-year money-back guarantee as well as a 1-year warranty on the RCC7 plus lifetime tech support
  • Comes with European-style Brushed Nickel Faucet, complete filter pack, tubing, wrenches for installation, feed water adapter for both 1/2″ NPT & 3/8″ COMP, drain saddle, spare fittings and O rings, and user manual

 

iSpring RCC7P 5-Stage Residential Under-Sink Reverse Osmosis Water Filter System w/ Booster Pump – WQA Gold Seal Certified, 75 GPD

Now why would you prefer the iSpring RCC7P over the RCC7? Think of the “P” as standing for “pressure.” The RCC7P is perfect for when you have low incoming water pressure. It boosts the water pressure high enough that you can make full use of a reverse osmosis water filter. It also has the side effect of increasing the speed at which the filter purifies water.

Just like the RCC7, the RCC7P gets rid of more than a thousand pollutants, from manmade chemicals to naturally-occurring minerals that are poisonous to humans. It has the WQA Gold Seal for quality, safety, and durability. This Gold Seal is not easy to come by. Companies that get this rating on their products have done intense testing on them over time.

More features of the iSpring RCC7P Reverse Osmosis Water Filter System:

  • iSpring offers a 1-year money-back guarantee as well as a 1-year warranty on the RCC7 plus lifetime tech support
  • Holds up to 2.5 gallons of water ready at a time
  • Comes with European-style Brushed Nickel Faucet, complete filter pack, tubing, wrenches for installation, feed water adapter for both 1/2″ NPT & 3/8″ COMP, drain saddle, spare fittings and O rings, and user manual

 

Recommendation

The choice between these two filters is simply a matter of knowing how much water pressure your home has. If you’re at the low end of typical residential water pressure, say around 30 to 40psi, consider getting the iSpring RCC7P. It increases the water pressure so that the filter works effectively.

Otherwise, if you have normal municipal water pressure entering your home, the iSpring RCC7 will work well for you.
