How to Read the Chart Above

Price.  Current prices listed online for these whole house water filters.  Prices are subject to change.

Estimated Media Life.  Media is the filtration medium used - typically a charcoal-based carbon along with other high-grade filtration options.  The life of it can vary dependent upon factors such as the combination of media used, the grade of the media, and its source.  To have a long-lasting media life, it is typical to combine charcoal-based products with bacteria-inhibiting media such as KDF-55 to ensure the safety of the water.

What's Replaced.  Some companies recommend changing out the entire main tank of a system to change the filtration media, and others only require you to empty it and refill it.  This is a consumer preference.  A high-quality tank will last much longer than the media life.

Media.  The media is the filtration media used.  As mentioned above, it is usually a carbon-based media used in conjunction with a bacterial-inhibiting media to ensure safe and healthy water.

Certifications.  Much like you see an electronic device with a certain certification, such as UL for example, water filtration systems can also have certifications. Typically the certification is from the WQA (Water Quality Association), ANSI/NSF, or UL.  Media can be certified, as well as the entire system.  Individual parts such as the tank, pre-filter, fittings and others parts can also be individually certified.  Don't be fooled by a system that is certified and think that provides you a good warranty or satisfaction guarantee.  While the system may be certified as a whole, that usually lends itself to a shorter warranty and guarantee.  Certifying an entire system is costly and those costs are passed on to the consumer.  

Pounds of Filtration Media Included.  We like to include this measurement on our charts because some companies like to talk about the expensive media used, but then only include a tiny amount, barely enough to make a measurable difference.  

GPM (Gallons/Minute Rating).  GPM is important because you need a healthy flow to achieve adequate water flow in your home.  A good system will not impact your GPM rating at all.  That's why it's so important to choose a system that meets or exceeds the flow rate you have in your home.  You don't want to negatively impact the pressure in your home.  Our PurHome X-1000 is a high capacity whole house water filtration system that will not impact your flow rate for homes even as large as 5,000-6,000 square feet.  If you're not sure of the appropriate sizing, just ask.

Warranty.  Pay careful attention to the warranty of your system.  Tanks and all components should be warranted for a material amount of time.  10 years is the gold standard.  This means that if you should experience a leak or other problem not caused by your plumbing connections, it will be covered and you can get a replacement.

Pre-filter.  Pre-filters, or often times called sediment filters, are designed to filter sediment from the water before it flows into the main filtration tank.  You can see a picture of the pre-filter in the picture at the very top of this page.  The blue canister on the hanging from the left side is the pre-filter. Some systems do not have a pre-filter at all, which will significantly decrease the life of the media.  Pre-filters vary in their micron rating.  The smaller the micron rating, the more particulate the filter will prevent from going in to the main tank.  So, a .35 micron rated filter will filter more than a 5 micron rated filter, but it can also clog up faster.  For a high capacity filter, a 5 micron filter strikes the right balance between fine filtration and adequate flow rates.

Gallon Capacity.  This is a rating on the media capacity.  It is a close approximation to the media life, based on average gallons per water used in an American home.

Inhibits Bacterial Growth.  As mentioned above, it is necessary to couple carbon-based media with a bacterial-inhibiting media to prevent bacterial growth in the water.  That's why small filters such as Brita or manufacture-brand fridge filters only have a very short lifespan, because there is no bacterial-inhibting media used. For whole house water fiters, it would not be feasible to be changing out the media that often.  Therefore, always insist on a system that uses a bacterial-inhibiting media such as KDF-55.

Reduces Chlorine, Chloramines, VOCs, SOCs, Lead, and Other Heavy Metals.  These are the primary problems with municipal water quality.  Reducing or eliminating these are essential to healthy water.  While chlorine is relatively easy to remove with a simple carbon-based media, chloramines (a combo of chlorine and ammonia) are not easy to remove without a specialized media designed to remove it specifically.  Since more and more water municipalities are disinfecting their water with chloramines, it is imperative to have a filtration media to remove them.  Lead and other heavy metals also require specialized media to remove. Note that most whole house systems do not remove all of the fluoride.  Full fluoride filtration is best removed at the drinking water level. 

Electricity and Backwash Required.  With well water filtration systems, it is very common to require electricity for a backwashing valve.  This is how the system self-cleanses daily to ensure the waste water remnants are removed from the system. However, in city water filtration, it is unnecessary.  In a well-designed city water filtration system, the water will flow in a upward flow.  This ensures that the media does not create channeling.  Channeling occurs when water flows down through it and takes the path of least resistance.  Since the water is always taking the same path, it does have good surface coverage with all the media.  The media will wear out quickly and be less effective.

Performance Guarantee.  A performance guarantee is just that: will the system perform as advertised and for how long does the company guarantee it?  At PuriTeam, our PurHome whole house city water filtration systems are guaranteed for 10 years, and in some cases, even longer.  What this means is that if for some reason your water is not being effectively filtered after say, 7 years of a 10 year guarantee, you would be entitled to a 30% discount off of new media.  A guarantee like this is hard to come by.

Licensed Plumber Required for Warranty.  Pay careful attention if you're a do-it-yourselfer.  Many companies will require you to prove the system was intalled by a licensed plumber in order to honor their guarantee.  At PuriTeam, we know there are many customers who like to install the system on their own.  We don't think this should invalidate a warranty.  As long as the system installation follows our provided instructions, we honor our guarantee whether a plumber installed it or not.

Satisfaction Guarantee.  Let's face it, the cost of a whole house water filter is not inexpensive and we feel your purchase should be backed up by a super satisfaction guarantee in the event that you're not happy with its performance.  Our six-month satisfaction guarantee is unparalleled in the industry.  When we say we stand behind our products, we mean it. 


Among the many options for a whole house water filter system for a large-sized home, the PurHome X-1000 is the clear choice. With the combination of a guaranteed media life of 10 years, and a 10 year system warranty, and the best filtration media available on the market today the PurHome X-1000 can’t be beat. Not only does the PurHome X-1000 come with a ten year warranty, but a performance guarantee for 10 years (a pro-rated performance guarantee). There is also a six-month satisfaction guarantee - if not satisfied after installing, you can return it for up to 6 months from purchase date.

With NSF certified material and components, the PurHome X-1000 is one of the highest-quality whole house water filtration systems available. The X-1000 has a million gallons capacity, which far exceeds the competition.

The PurHome X-1000 also uses over 90 pounds of total media, including NSF-Certified KDF-55 media, bitiminous carbon, coconut shell carbon and centaur carbon, which removes chlorine at rate over 99%, as well as removes heavy metals like lead, mercury, copper, nickel, chromium, and other dissolved metals, and extends the life of the carbon stage.  Insist on KDF-55 media for the most effective filtration money can buy.  The PurHome X-1000 also incorporates three different types of carbon-based medias for Chloramines and VOC removal. This filtering combination provides long lasting and effective filtration.

It is the only filter that effectively filters out the major contaminants from city water at an affordable price.  For example, many of the other filters will not remove chloramines, which are potentially dangerous additives used to disinfect water. Chloramines are a combination of chlorine with ammonia.  The effects of chloramines have not been widely studied yet, but it is considered no less dangerous than chlorine to your health. The PurHome X-1000 whole house water filtration system effectively removes chloramines from your water.

The PurHome X-1000 requires no electricity supply and does not produce wastewater (i.e. backwashing) like other filtration systems. This whole house water filtration system is environmentally-friendly and will not raise the price of your electricity bill.  Not only this, but installation is basic for a plumber or a handy homeowner with plumbing knowledge.
