Do I Need a Whole-House Water Filter?

If you’ve ever noticed an “off” taste in your tap water or a line of soap scum in your tub, you may have wondered if you need a water purification system. There are several different systems that can remove contaminants from tap water, and one of them is a whole-house filter. Read on for more information on how to know if you need one.

What Is a Whole-House Water Filter?

Awhole-house filtration system is installed at the point of entry where water from your well or municipal source comes into your home. The filter removes impurities from the water before it reaches your faucets, dishwasher, ice maker, and washing machine. Installing a whole-house filter eliminates the need for point-of-use filters at all the faucets in your home.


A whole-house filtration system can offer several benefits:

  • Improving the taste and smell of tap water
  • Removing chlorine and other chemicals
  • Protecting pipes and appliances from mineral buildup

If you still aren’t sure whether you need a whole-house water filter, think about your answers to the following questions:

Does My Home’s Water Taste and Smell Bad?

While your water is likely safe to drink (all tap water must meet federal safety standards), there are still several things that can cause it to have a bad smell or taste:

  • Sediment
  • Chlorine and other treatment chemicals
  • Dissolved metals such as lead and nickel
  • Minerals

If you don’t like the taste of your home’s water, you could pay for bottled water or get a drinking water purification system. However, a whole-house filter is often the most cost-effective choice.

Are Clothes and Dishes Hard to Wash?

It can be extremely frustrating when you pull your clothes out of the dryer only to see that all the colors are dull and the whites are closer to grey. Or maybe you’ve noticed that your dishes come out of your dishwasher with an unattractive film on them. One of the things that can cause these issues is the presence of iron and/or minerals in your water (known as “hard water”). It's impractical to try to install point-of-use water filters at your home’s dishwasher, washing machine, and shower faucets. The easiest solution is to get a whole-house filter that eliminates those mineral and metal contaminants before the water touches your dishes and clothes.

Do My Sinks and Tubs Have Soap Scum?

Are there noticeable lines of dingy soap scum around your tubs and sinks? The most likely cause is hard water. The minerals in hard water, particularly calcium and magnesium, fight against cleaners and soaps. This means that soap residue doesn’t easily wash away. Hard water can also make it difficult to get a good lather with laundry detergent, body wash, and shampoo. If your home already has a water softener, a whole-house filtration system can improve the quality of your water even more.
