How to select the right whole house filter for your home

Your water carries with it a story; where it came from, what it was treated with, and where it’s going all act as a three-part narrative to the tale of what’s in your water. Sometimes the story has a happy ending, and sometimes it’s told like an epic, with twists and turns along its journey to your home.

For example, municipalities treat your water with chlorine or chloramines in order to disinfect and kill germs that may be present before it ends up at your tap. But it’s often the case that even after being disinfected, contaminants can enter your water on its way from the city water treatment plant to your home. And that issue isn’t limited to your municipality. Even private or shared well water can carry unknown contaminants from the groundwater to your glass. This can include contaminants like fluoride, cysts, lead, mercury, herbicides, pesticides, industrial solvents and more. These contaminants can have nasty side effects, ranging from an undesirable color taste and odor to serious health issues.

Most people only consider the risks of drinking unfiltered water — but what about the water that’s already been filtered? Sometimes it’s important to take a step back and consider the water we shower in, wash our pets in, clean our clothes with, and what goes into our family’s food and drinks.

At Aquasana, we’re passionate about contaminant reduction and providing healthy water throughout the entire home.

Different Types of Water Treatments

Before choosing a whole house water filtration system, you need to find out how your water is treated. We offer four different whole home systems specifically tailored to the type of water in your home, whether it’s municipal water treated with chlorine/chloramines, or untreated well water.

Chlorine Treated Water

If your water supplier treats your water with chlorine, you should be able to both smell and taste it. Chlorine can be harsh on skin and hair, causing WhyAquasana_Feature-2everything from dry skin to split ends. Bright colors could also be a casualty when your favorite clothes meet chlorine-treated water in the washing machine.

Chloramine Treated Water

Chloramines put their own signature on your belongings. Though it’s not as harsh or as noticeable as chlorine, it is still an aggressive disinfectant that sticks around a lot longer. While this prolongs the amount of time your water remains disinfected, it also makes filtering more difficult. Another concern about chloramines is their potential effect on lead or copper pipes. The CDC states, “Chloramine can change the chemical properties of the water, which can affect lead and copper pipes.” While the CDC insists that this is not an issue because lead and copper are strictly regulated, we know that the EPA has struggled to contend with lead in recent years.

Well Water

Private well water should always be filtered, as it is not treated municipally. Well water is at risk of contamination from bacteria, viruses and other organic compounds. Naturally-occurring chemicals such as arsenic or radon can make their way into private water supplies, as well as pesticides used on local land. The CDC reminds well owners that they are responsible for ensuring that their water is safe from contaminants. Contaminated well water can cause everything from stomach issues to reproductive problems and neurological disorders. With our most vulnerable population— children, the elderly and the ill— there is an even greater risk of exposure.

To find out how your water is treated, review a copy of your Consumer Confidence Report online.

Consumer Confidence Report

The EPA requires water suppliers to distribute a Consumer Confidence Report (CCR) or an annual Drinking Water Quality Report. You should receive this report by July 1st each year. Some cities even publish their water quality report in their semi-annual magazines. Within the report, you’ll see just how your water is treated. You’ll also be notified if there are any specific concerns regarding your area.

You can access your water quality report year-round by visiting your city’s official website. For example, residents of Austin, Texas would visit

If you’re still unsure of how to access your CCR, check out this interactive map on the EPA’s website. While not all water suppliers have provided a direct link, you can type in your zip code and find out exactly who your water supplier is and how to contact them.
