Is a Pre-filter Needed With a Water Softener?

Is a pre-filter needed with a water softener?

Perhaps you own a water softener, but are wondering if a pre-filter should be installed before your softener? Or perhaps you’re considering installing a water softener but want to get it right from the get go?

Depending on the quality of water coming into your home—a pre-filter may indeed be what you need!

Have You had Your Water Tested?

My first suggestion would be to get your water tested. Water can be tricky and the best wayDeluxe Field Test Kit 2404 to figure out what you need to do is to have a water analysis conducted on your water by a local water treatment professional.

Sometimes people shy away from a “water test” because they worry that a salesman is going to put undue pressure on them to purchase. The truth is, if a company offers a “free water test” then it should be exactly that—a free water test with no strings attached. If a water professional puts pressure on and makes you feel uncomfortable, then kindly say “good bye”. Hopefully you’ll find a water treatment professional whom you trust and feel comfortable doing business with, because a WATER TEST is your absolute best way to know what’s in your water—and subsequently, get the best assessment on what  equipment is needed to give you the clean, good water you seek!

Why Prefilters are a Great Companion to Water Softeners

A prefilter is often highly recommended with the installation a whole-house water softener system. This isn’t because a water softener can’t do a good job, but simply because there may be contaminants in your water that a water softener isn’t made to remove.

Potential Reasons For a Prefilter

Perfect Combination for Outstanding Water in the HomeDIRT, SEDIMENT AND SAND IN WATER

If the water entering your home looks milky, hazy or cloudy, you may have dirt, sand, sediment, clay, silt, industrial waste, or other organic substances in your water. A whole-house prefilter can play an important role in preventing dirt, sand and other large particles from entering your home’s water supply and potentially damaging the fine moving parts and the water softening media inside your water softener.  A prefilter will also protect the appliances and fixtures in your home.


If you’ve seen red staining in your sink or tub, this may be an indication of high iron content in your water. Colors or staining in water can also come from galvanized iron, steel, or cast iron pipes in a home. Manganese often accompanies iron and results in dark brown or black staining. Since softeners are not designed to address undissolved iron and manganese, a whole-house particle filter is good solution for reducing and/or eliminating insoluble iron and manganese. Again, this particle filter can also serve as a barrier protecting your water softener/conditioner from clogging and thus extending the life of your unit.

These are just a couple of reasons why a prefilter may be recommended. After your water test is complete, discuss all possible options with your water treatment professional.

  • Vinegar is a fab descaler, I use neat and also use a 50/50 mix with water in an old spray boltte to clean the bath sink and shower. White vinegar doesn’t smell so much but is much more expensive and the smell doesn’t linger long. Also no worry about getting chemicals on skin as with cleaning products especially in the bath and sink.It’s also great for the windows in this form, old newspaper and they’re gleaming.I do use bleach but again I use an old spray boltte, 1 tablespoon in 500 mls of water and is great as a kitchen spray, I always spray the insides of cups and mugs before they go in the dishwasher.Washing up liquid is the only other cleaning product I use and that’s it!! AND i am a bit of a clean freak and these 3 things do the job just fine.Great blog!!

  • I don’t think it can hurt to have a pre-filter on for the water softener. It is really important to have clean water. I don’t think anyone out there wants to have water that is full of chemicals or diseases. If you think it is a good idea to get a filter, don’t hesitate. I think you should, at least, get your water tested like you said.
