How Whole House Water Filter Systems Work

The most convenient and cost-effective way to filter water for your entire home is to install a water filter whole house system.

While whole house water filtration systems can be more expensive than those for a single point of use, you only need one. Plus, you can then feel secure about drinking the water from any cold water tap in your home.

How Whole House Water Filter Systems Work

The system is installed on the main water line coming into the house before it divides. Therefore, filtered/treated water goes to the water heater and to all water taps.

A water filter whole house system will have from one to five filters. The more filters and the smaller the particles they remove, the better the filtration will be. If there are multiple filters,

it is common, to begin with a large filter, often a 5-micron filter, to remove sediment. Then, a .5-1.0 micron filter removes smaller sediment and elements such as lead or mercury.

An iron filter will remove iron typically found in water supplies. This is ferric iron which is basically rust. It’s larger, and most of it will be removed with a sediment filter. The iron-type that requires an iron exchange filter is called ferrous iron and consists of dissolved iron.

The next stage is often a carbon filter that will remove most chemical contaminants.

There is a long list of pollutants carbon is effective against. Keep in mind that your water supply might have some of these but certainly not all of them.

They include acetic acid, acetone, benzene, chloromine, chloroform, detergents, dyes, gasoline, herbicides, insecticides, ketones, methyl-based chemicals, pesticides, propyl acetate, solvents, toluene, xylene and many more.

Many organic contaminants are removed as well, when present in the incoming water supply.

These include 2 and 4-D, alachlor, aldicarb, bromoform, e-coli, microbial cysts and many others. The better water filter whole house systems will remove most or all of these.

How to Choose your Whole House Water Filtration System

There are several key factors to consider as you choose the best home water filter for your house.

Flow Rate: Each whole house filter system has a unique flow rate, the number of gallons they can treat per minute. On the market, you’ll find models with flow rates from 12-40 GPM, or gallons per minute.

The larger your household is, the higher your flow rate will need to be. If showers are being taken while laundry is running, and someone else is washing the car, you’re going to need a system on the high end of the spectrum.

Keep in mind that the water filter whole house system needs to filter enough water for both hot and cold purposes.

Number and Size of the Filters: By size, we don’t mean the dimensions of the filter but the size of the particles it will remove.

The more stages and the smaller the contaminants are that can be removed, the cleaner your water will be.

It might be very helpful to know your water’s condition so that you know how much it needs to be filtered. Request a copy of the Consumer Confidence Report from your local water utility.

If you have a well, review the test information on file with the local building code office. If it isn’t current, consider having your water tested. You can find a state-certified tester by contacting the EPA’s Safe Drinking Water Hotline at 800-426-4791.

Filter Life: Filters are rated for a certain number of gallons passing through them. If you receive a water bill, you should be able to see how many gallons per month flow into your home.

Capacities for filters range from 40,000 gallons to 150,000 gallons before they need to be changed. The relative condition of the incoming water will also affect filter life, but the numbers are general guidelines. This number will sometimes be consistent with flow rate, with filters for units with a higher GPM flow rate also being able to filter more water during its lifetime. Using a high-capacity filter is probably the most cost-effective choice.
