When choosing a water filtration system for your home, there are many factors to consider. As you research different companies to help with water filtration, you want to find a company with your family’s best interest at heart. Water filtration companies like Culligan Water get business often because they are a recognizable name. But as the market has grown and families have changed, their business practices have stayed the same. There are even better options available. ONIT Home offers a water filtration system with your family’s needs and security in mind.

Who Is ONIT Home?

ONIT Home is a Texas-based company that specializes in simplifying home services for families. You don’t have to worry about making complicated home decisions on your own. As our name implies, when something happens to your home and you need help, we’re ONIT! ONIT Home offers smart security, solar energy, water filtration, insurance, and more. With our total home options, affordable pricing, and maintenance plans, ONIT Home water filtration is the best choice because we serve the modern family where they are and give them the safest water possible. ONIT Home is focused on the security of your home and family as a whole, not just the water system. Your home’s safety, energy, water, insurance, and more are important to us.

Who Is Culligan Water?

Culligan Water is a water treatment company based out of Illinois that provides many water-related services. They serve both residential and commercial properties. They offer water testing, water filtration, bottled water delivery, well water treatment, and more. However, as families’ needs have changed over the years, Culligan Water has not updated or changed its business plan. This means that they do not have the best pricing or overall systems in the business anymore. Culligan Water has been around for 85 years and offers a variety of water services, but no overall home care, and no maintenance or insurance plans.

Comparing ONIT Home and Culligan Water

There are many similarities and differences in what ONIT Home and Culligan Water offer in their water filtration departments. Both Culligan Water and ONIT Home provide services for residential areas and commercial areas alike. The services that both companies provide are:

  • Whole-home water filtration
  • Hard water conditioning
  • Reverse osmosis options
  • Free home water tests
  • Professional installation

However, there are many features that ONIT Home offers that Culligan Water does not have, such as:

  • UV water purification

  • Affordable pricing
  • A 10-year included warranty

UV Purification

ONIT Home provides UV Water Filtration that specializes in taking bacteria out of the water that you drink. UV Light Water Purification removes viruses, microorganisms, and bacteria from drinking water. ONIT Home is dedicated to providing the best and safest water purification options for homes and families as they grow. Providing bacteria-free drinking water is critical to keeping your family healthy.

The UV rays in this process attack microorganisms and destroy their DNA, ensuring that they do not come back or regenerate. Using UV Light Water Purification also ensures that your water is cleaned without any chemical additives, so your water remains in its purest form. You can learn more about the specifics of how our UV Light Water Purification system works here. Culligan Water does not use UV Light Water Purification systems.


While both ONIT Home and Culligan Water offer home installations, ONIT Home guarantees fast and free home installation. In less than 24 hours from your phone call and quote, your system can be installed, giving you clean water the very next day. Unlike Culligan Water, ONIT Home includes the installation parts in the pricing, so you don’t have to spend any extra money.

Water Tests

Both ONIT Home and Culligan Water offer free water testing. This is when the company comes into your home, gathers water samples from various places, and tests them. These tests look for harmful chemicals or minerals that may be hiding in your water. These chemicals and minerals can cause buildup in drains, streaks on dishes, and in extreme cases, health issues. Water testing is an important initial step in any water filtration system.

Warranty and Maintenance Packages

ONIT Home’s water filtration systems have a ten-year warranty. There are also affordable maintenance options available, so you can protect your investment. This means that twice a year, a representative from ONIT Home will come to your home to check on your system. We will repair any damage and care for your equipment, guaranteeing a longer lifespan for your water filtration system.

With a ten-year warranty and affordable maintenance package, owning your top-of-the-line water filtration system is hassle-free. The ten-year warranty covers all labor costs and replacement parts, so there will be no surprising fees later on down the line.


Unlike Culligan Water, ONIT Home offers Smart Choice Financing. This means that you can pay your bill gradually over time rather than breaking the bank upfront. The rates for ONIT Home are also more affordable than Culligan Water’s rates. This is because we understand that the needs of every family are different. Your financing for your new home water filtration system can be as low as fifteen dollars a month.

Over-The-Phone Quotes

ONIT Home guarantees our final price on the phone when you call to request a quote. Culligan Water does not even offer quotes over the phone, but we understand the complexity of family schedules. You can get that quote over the phone, and the final price on that phone call will be guaranteed. ONIT Home prioritizes families and their needs.
