When you’re considering a whole house carbon water filter you’ll want to familiarize yourself with the following criteria. These are the same criteria we used to compile the filters listed above, so it’s worth educating yourself before you go out and spend significant money on a system.
Whenever you purchase a water filtration system, the first thing to do is get your water tested for contaminants. This will give you a precise reading of what it is that you are facing in your home’s water supply, and allow you to tailor your filter purchase to remove these contaminants.
If your water is sourced from a private well, then the only real choice is to get it professionally tested to find out which contaminants are present. This will typically run you between $100 and $500, but you’ll get precise readings of contaminant quantities present.
You could also opt for a home well water test kit, which will give you a more general idea of contamination (heavy metals, water hardness, bacteria, etc.), but the results may be lackluster.
For municipally sourced water, you can count on water quality reports. These reports are mandatory for public water utilities to create and provide for free. They list all the contaminants detected in a water supply. Additionally, there is the EPA’s and the EWG’s Tap Water Database which both archive water quality reports and make them available online.
A professional water testing is still recommended in this scenario, however, as it will give you precise contaminant readings also taking into account contamination that might happen while the water travels from the utility to your home.
The NSF is an independent organization that conducts testing and certifications on several consumer products including water filtration systems. Whole house systems with NSF testing/certifications are somewhat rare, but if you do find one, you can be sure you’re getting the contaminant removal level advertised by the manufacturer.
Several whole house carbon water filters come with a standard 42 NSF rating, which is the standard for a filter’s ability to remove chlorine and particulate matter. The PIONEER is NSF standard 53 certified to remove lead.
The water flow rate is a measure of the flow capacity that a filter system can provide. In other words, it measures the total quantity of water a system can filter at one time. For a whole house filter system where all of the home’s water supply will flow through the filter, it’s important to make sure the flow rate is sufficient to accommodate your usage.
Flow rate is typically measured in gallons per minute (gpm), but manufacturers will typically also include the number of bathrooms a system is capable of providing.
For a large house with 4 to 6 bathrooms, you’ll need at least 10 to 15 gpm. If you opt for a system with a flow rate that’s too low, you’ll have pressure issues when running different outlets simultaneously. On the other hand, if your purchase a system with a flow rate above your requirements, you’ll be adding an unnecessary cost.
Whole house carbon water filter systems are more complex to install than smaller under sink systems, but that doesn’t necessarily mean you can’t install one yourself. Most systems can be installed on your own provided you have basic DIY skills and a little plumbing knowledge. Also, manufacturers typically include the necessary bypass valves and fixtures as well as detailed installation instructions.
If you feel like installing a whole house system is beyond your skill level, then hiring a plumber to complete the installation for you is always an option.
When it comes to maintenance, all that’s generally required is occasional carbon filter cartridge changes for cartridge-based systems. Typically, cartridges must be changed every 6 to 12 months.
Whole house systems must be installed where your main water line enters your home. As such, you’ll need enough space to install the system at that point.
One advantage cartridge-based systems have over tank-based systems is that the space required for installation is significantly less.
If you’re considering a large purchase like a whole house water filter, then budget will likely be a major consideration. While whole house carbon filters aren’t cheap, they tend to have long lifespans and capacities, so will provide a lot of value over time.
If you’re considering a whole house filter, you should be aware of the cost differences between cartridge-based systems and tank-based systems.
Cartridge-based systems have lower up-front costs, but as they require frequent filter replacements, the costs will add up significantly over time. Tank-based systems, on the other hand, have higher up-front costs, but as the tank has a longer lifespan and greater capacity, the costs tend to average lower in the long run.
Another significant consideration when looking at whole house carbon filter systems is the product warranty and/or money-back guarantee. As a system of this type is going to set you back at least several hundred dollars, it’s worth shopping around for a system with a solid warranty and money-back guarantee.
More on Whole House Carbon Water Filters
A whole house carbon water filter is simply a point-of-entry water filter with some form of carbon filter media as part of the filtration process. These filters often feature other filter stages with different filter media, and can either be cartridge-based or tank-based systems.
Being a whole house system, these filters will remove contaminants from all of the water flowing into your home.
Whole house activated carbon filters use a process known as adsorption to remove chlorine/chloramine, disinfection byproducts, pesticides, and all kinds of organic chemicals from your water supply. Carbon filters are also good at removing certain metals.
They are ideal for filtering water from a municipal supply, as they excel at removing water disinfectants, which are very commonly used in the water treatment process.
Activated carbon is carbon that has been treated to make it highly porous. It is produced by placing a carbonaceous source material like bamboo, coconut husk, wood, etc., in a tank without oxygen and then subjecting it to extremely high temperatures. After this, it’s exposed to various chemicals like argon or nitrogen, and then once again superheated in a tank.
Activated carbon can also be produced through a chemical process in which dehydrating agents like phosphoric acid are applied to break down the bonds binding the cellulose chains together. Then heat is applied to carbonize the material before its washed to remove any remaining dehydrating agent residue.
At this point, the carbon becomes exceptionally porous, and its adsorptive surface is vastly increased. It can readily adsorb a wide variety of organic and some non-organic contaminants.
When unfiltered water flows past activated carbon in a filter, contaminants are effectively ‘pulled’ into the tiny pores, trapping them and removing them from your water.
Catalytic activated carbon is the next step above regular activated carbon. It’s enhanced through a chemical process that renders the surface more absorbent to contaminants that can’t be adsorbed by regular activated carbon. This carbon type can remove chloramine as well as hydrogen sulfide – contaminants that can’t be readily removed by normal activated carbon.
When it comes to whole house activated carbon water filters, there are several different forms to be aware of.
Whole home granular activated carbon filters are made using carbon that has been ground up into small pellets. This filter type, by its loose design, allows for a greater flow rate but is not as effective as the other type described below. As the feed water has less contact time with the carbon, there is less opportunity for the carbon to adsorb contaminants.
This tradeoff is a consideration when shopping for a whole house carbon filter. For larger homes with multiple bathrooms, granular activated carbon filters can be the preferred option due to their superior flow rate.
The other major filter type is carbon block filters. These filters are made from ground up activated carbon that is then bound together using a food-grade binder.
Carbon block filters are significantly more effective at removing water contaminants but offer a lower flow rate than their granular counterparts.
As mentioned previously, catalytic carbon whole house water filters are enhanced versions of typical activated carbon. They are available in both granular and block forms, although the block form is more common.
Carbon filtration is the most cost-effective method for removing chlorine and chloramine from your water. This makes it an ideal choice for treating municipally-sourced water which is often treated with these chemicals.
Carbon filtration will also remove a variety of other contaminants like pesticides, herbicides, disinfection byproducts, hydrogen sulfide, VOCs, lead, and many more. It also excels at improving the taste and aesthetics of water, which is why carbon filter stages are so often included as a component of other multi-stage water filters.
