How to Choose a Home Water Filter

If you’re considering installing a whole house water filtration system for your home, there are several considerations to keep in mind. Keep reading to learn the benefits of a water filtration system and tips for finding the right one for your home.

Why Whole House Water Filters?

Whole house water filtration systems treat all the water flowing into your home. These systems — also known as point-of-entry (POE) systems — connect to your home’s main water supply, meaning all your faucets, showers, washing machines, and other water-using appliances dispense filtered water.

Point-of-entry systems are different from point-of-use (POU) systems, which include products like shower filters and undersink and countertop filters. Wherever you install a point-of-use system, it only treats water in that specific location, not the entire home. With a point-of-entry system, you can rest easy knowing you’re getting a one-stop solution for all your water needs.

Tips to Choose the Best Whole House Water Filter

Getting a whole house water filtration system is an investment, so you want to ensure that you’re getting the right one for your home. Here are some tips to help you narrow down your choices.

Consider the Filter Size You Need for Your Home

Many whole water filtration systems are sized based on the number of bathrooms in your home. Some filtration systems are designed to accommodate homes with 1-3 bathrooms, while others are built to treat homes with 4-6 bathrooms. Knowing the number of bathrooms in your home is usually a quick, easy way to help narrow down your choices and determine the best size for your house.

Find Out the Flow Rate of Your Faucets and Dispensers

Flow rate is the amount of water able to flow through your water dispensers such as faucets, showers, dishwashers, and toilets. It’s important to know the flow rate of your dispensers because if it’s lower than the water filter’s flow rate, there’s a chance of leaking and burst hoses. On the other hand, if the flow rate is higher than the water filter’s flow rate, the water flow may be too weak, potentially causing choking due to air filling.

You can calculate the flow rate of your dispensers by yourself, but if you schedule a free in-home water consultation, a home water expert will ensure your filtration system meets your home’s requirements.

Determine the Purpose for Filtration

Every home is different, especially when it comes to water problems. Your house’s water supply may come from a well, which can present challenges such as water hardness due to groundwater flowing through or over limestone. Or perhaps you get water from your city’s supply, which can be brimming with chlorine that causes your water to taste and smell foul.

These are just some examples of why you may need a whole house water filtration system. Take time to examine your water supply and see if you come across any of these common water issues:

  • Discolored, orange, or red water and staining
  • Blue or green staining
  • Sediment or debris, including salts, soil, and micro rocks
  • Rotten egg smell
  • Metallic taste
  • Yellow staining on kitchenware
  • Clogged pipelines
  • Rusting faucets
  • Patches on bathroom and toilet floors

Seller and Manufacturer Credibility

Whenever you’re looking for a whole house water filtration system, ensure that it’s certified by the National Sanitation Foundation (NSF). When you purchase an NSF-certified product, it means:

  • Only FDA-approved raw materials were used to make it
  • It passed numerous tests for material safety, design, construction, and performance
  • Harmful chemicals won’t contaminate your water

You should also look into the sellers’ and manufacturers’ shipping, services, and warranty. Pentair provides free shipping over $49, a comprehensive system warranty, and a money-back guarantee. We also offer white glove service and our Water Shield Autoship Program, so you can take the worry out of maintaining your water treatment system.

What Kind of Water Filtration System Do I Need?

There are many different types of water filters for your home. Many whole house water systems are designed to reduce up to 97% of chlorine in your water supply. Water softeners can reduce moderate to very hard water to help lessen scale buildup and extend the lifespan of your appliances. Additionally, UV systems may provide fast-acting disinfection without using harmful chemicals. With all these options at your disposal, it can be difficult to know how to choose the best water filter for your home.

The best and easiest way to determine the type of whole house water filtration system you need is to purchase a home water testing kit. It tests for common contaminants found in water, such as chloride, total iron, manganese, water hardness, copper, and more. Our 16-Point Rapid Water Test gives you a clear snapshot of what’s in your water, so you can get the right solution for your home.
