How to choose a water treatment system in Sioux City

When looking for a water treatment system, first determine what contaminants, tastes or smells you’d like to remove from your water. Once you know your goal, you can narrow your search down to the types of water treatment systems in Sioux City that work for you:

  • Whole house water filters treat all your water as it enters your home. Whole house systems work well for homes with hard water, but they can treat for multiple contaminants. The alternative is point-of-use systems, which treat water only at the point where the filter is installed.
  • Activated carbon filters use small, porous carbon particles to trap contaminants as water passes through. These filters are particularly effective at removing the taste of chlorine.
  • Ultraviolet disinfection uses UV radiation to kill microorganisms, such as viruses and bacteria. UV systems are a good choice for those with compromised immune systems who are concerned about illness.
  • Water distillation purifies water by boiling it to separate the vapor from the contaminants. While distillation is highly effective for removing germs that can cause illness, it also removes beneficial minerals.
  • Reverse osmosis water filtration works by pushing tap water through a semipermeable membrane to remove particles. RO water filtration is popular for improving the taste of water while filtering out viruses and bacteria. It also removes metal ions.
  • Salt water softeners use an ion exchange process to remove excess minerals from your water. They typically apply to the whole house and can help with hard water deposits and soap scum.
  • Salt-free water softeners, sometimes called water conditioners, modify minerals so that they do not adhere to pipes or cause other problems associated with hard water. Salt-free softeners might appeal to those looking for a more eco-friendly solution to hard water.

In addition to these products, Sioux City water treatment companies also offer installation, maintenance and repair. Most also provide free in-home water analysis to identify your problems.

Before choosing a company, look online for customer reviews. Then, make sure its products come with warranties, and ask about money-back guarantees, especially if you have not tried home water treatment before.

How much does a water filtration system cost in Sioux City?

In Sioux City, water filtration systems cost between $800 and $1,300, including installation. The price of water treatment varies, depending on the number and type of filters you need and how much of the house you want treated. For example, a whole house water treatment system costs more than point-of-use filters.

Certain types of water treatment systems, like salt-based water softeners and reverse osmosis systems, use extra water and could cause an increase in your water bill. While salt-free water softeners tend to cost more initially, they use less water than salt-based models.

Some Sioux City water treatment companies offer discounts and financing to help you afford equipment and replacement filters. Some products may be available for rent, as well.

Sioux City water softener and treatment system FAQ

Are permits required in Sioux City to install a water treatment system?

Point of use filters typically do not require permits, but Sioux City might require a plumbing permit to install water softener systems if you’re altering water lines. If you are reconfiguring any plumbing in your home to add water treatment components, contact the city to confirm whether a permit is necessary.

How do I choose a water softener?

When choosing a water softener, decide if you prefer salt-based or salt-free systems. Salt-based ion exchange systems typically use more water but cost less upfront than salt-free systems. On the other hand, salt-free systems are a more eco-friendly option.

How long does a whole house water filter last?

Whole house water filtration systems last about 10 - 15 years, but individual filters, cartridges and tanks require regular changing, cleaning or recharging. The frequency of this service depends on your equipment choices, so talk to your water treatment company about how often you should change these parts.

How much is a filtration system for well water in Sioux City?

The average cost in Sioux City is about $800 - $1,300 for a whole house water filtration system that removes sediment from well water. Expect costs to increase if you’re looking for other additional features, such as a water softener.

What do water filters remove?

Water filters come in a variety of types that target different contaminants. Reverse osmosis filtration removes chlorine and microorganisms. Activated carbon filters are effective at removing chlorine and particles but not minerals. Water softeners remove minerals but not viruses and bacteria.
