User Rating: 3 ( 16 votes)

The Krystal Pure whole house filters are stand-alone. This means that they can be used without requiring any other system, but they can also be combined with a softener, for a complete protection against tap water contaminants and hard water deposits. These systems require neither salt nor potassium, meaning that they are completely maintenance free. With their aid, you will keep dangerous water contaminants at bay, while also extending the life of other water systems such as the water softener or a reverse osmosis water filter.

A lot of people choose to combine whole house systems with reverse osmosis systems in order to obtain a more pure drinking water, although there are those who say that the R/O systems are outdated as they also remove good minerals along with dangerous contaminants. At Krystal Pure, there are two main filters to choose from: the KC10 system and the KC15 system. Both systems feature 25 GPM valves which deliver high flow rates, making these systems suitable even for very large estates. They also feature a space saving design, being able to fit in any 10 in.² space. This gives them quite an edge over the competition. For example, the Aquasana whole house filters support a 7 GPM flow rate, while the Pelican systems support a maximum flow rate of 15 GPM. Let’s see what other advantages they come with. Aside from the whole house systems, which are reasonably efficient, Krystal Pure also has some amazing water softeners that are worth checking out.

Krystal Pure Filter

General features

Both the K10 and the K15 use an innovative 17 stage filtration system which delivers clean water to every faucet in your home. Not only do they reduce the number of chemicals that you ingest by drinking tap water, but they also reduce the risks of absorbing chemicals through the skin during showers and baths, as well as the risk of inhaling chemicals produced by heated or agitated tap water. The systems come with Water Miser Rejuvenator valves which renew and refreshes all the filtration media. Thus, without requiring any maintenance on your part, the filtration media of a Krystal Pure system could last up to 10 years.

These systems also come with free source select valves. This is something that we have not seen at other whole house systems, despite the fact that it is a very useful feature. Basically, the valve allows you to choose whether you wish to use purified water or regular municipal water. After all, what is the point of using it when you want to water your plants or wash your driveway? Both systems come with a 15-year warranty for the tank, a 5-year warranty for the valve, and a 1-year limited warranty for parts and in-home labor. The warranty is pretty standard for whole house systems. However, some filters like the Culligan come with a lifetime tank warranty. Their tanks are so resistant that they can even be placed outdoors, being able to withstand hard weather conditions without experiencing rust and corrosion. Nevertheless, if you don’t plan on installing the system outdoors, a 15-year tank warranty will do just fine.

Technical specifications

As we already mentioned, the Krystal Pure whole house systems feature great valves that can support a flow rate of maximum 25 GPM. They each require a 10 in.² installation space. This makes them very small and compact, compared to similar systems on the market. They adapt to up to 1.25 plumbing pipes and fixtures. Despite being quite small, they each encompass a total of 1.5 Cu. Ft. of filtration media.

Krystal Pure Whole House Water Softeners

The softeners are perhaps the most efficient softeners that you can find on the market nowadays. They are certified by the WQA and they come with numerous advantages. First of all, they are sodium free, meaning that they only use salt or a salt substitute (potassium). They feature a two tank design which reduces the problem of salt-blocking. They also have a variable reserve which maximizes water and salt efficiency. The high flow engineering systems used by these water softeners meet 99% of the water usage needs of most large homes. Moreover, they are only 11″ wide, so they take very little floor space.  There are 4 main softeners to choose from, KS64He, KS15He, KS10, and KS5.

KS64HE WS System

This system has the largest capacity, namely 64,000 grain. This makes this softener ideal for very large estates. It can support peak flow rates of 19.5 GPM3 and it fits 3/4″ – 1 1/4″ plumbing fixtures. This system uses an innovative DURAEX resin which is covered by a great warranty of up to 25x’s longer than most competitors. Just like the whole house systems, it also uses a free source select valve which allows you to choose whether you wish to use softened water or normal tap water. It has a great UltraFresh feature which rinses away stale water during the times when little water is used, thus ensuring fresh water at all times. It comes with a 25-year resin, body, and tank replacement warranty and a one-year labor warranty.

KS15HE WS System

This system is identical to the previously mentioned water softener, the only differences lying in its capacity and its warranty. This system has a 50,000-grain capacity, being ideal for big homes. It is covered by a 20-year limited warranty, a 15-year resin replacement warranty, and a one-year labor warranty.

KS10 WS System

This water softener has a 42,000-grain capacity. Unlike the two softeners mentioned above, this system lacks the UltraFresh feature which rinses away stale water. It is covered by a 15-year limited warranty, a 10-year resin replacement warranty, and a one-year labor warranty.

KS5 WS System

Recommended for smaller homes, this softener has a 30,000-grain capacity. It lacks the UltraFresh feature of the previous softeners, as well as the free source select valve. It can be great for apartments of for very small homes. It is covered by a 10-year limited warranty, a 5-year resin replacement warranty, and a 1-year labor warranty.
