Water Filtration Systems
Improve your health with a whole home water filtration system
- Ditch bottled waters by removing contaminants from your drinking water
- Avoid health risks – remove chemicals and hardness from your bath water
- Reduce wear and tear on your plumbing and appliances
Clean, fresh water for every home.
Tap water is the most accessible source of water in our homes, and we use it for everything without pausing to consider its quality. But the reality is, tap water often contains minerals, and other contaminants. Hard water, a common irritant for homeowners across the country, contains minerals that can even damage our plumbing appliances, creating costly expenses in your home. Unfortunately, a city's most often solution for purifying our water is with chlorine - adding more chemicals in the water to make it safe to drink. You can efficiently fight against contaminants and chemicals in water with a comprehensive water test that identifies what's lurking in your water. Learn more about how you can get a free water test from ONIT today.

“When I called ONIT Water I was genuinely amazed at how helpful they were. Even though it became clear within minutes of the call that I was asking about a service they didn't even provide, Brad stayed on the phone with me for another 30 minutes just to help me find my own solution. He didn't try to sell me anything; he was just kind, transparent, and extremely helpful through and through. I don't think I've ever written a review for a company before, but they definitely earned my future business should I ever need their services. ONIT just REALLY want's everyone to have clean water, full stop.”
“Brock was my rep he was very knowledgeable and professional. The info he shared was so educational And I’m so happy I made the investment to get the water conditioning system installed. I love the results and the pure and gentle cleaning products as well. Totally a good investment!”
“Our home inspection company offered us a free water test and since we were new to the area we thought it would be a great idea just to see the results. Brock was our representative and he was awesome! He was very knowledgeable and personable! It was an exciting experience almost like a science experiment but it was also scary to hear that there are acceptable levels of toxic chemicals allowed to be in the water we use everyday! It was a no brainer for us to invest in the water filtration system and we love!!! It has saved us so much money and it has done wonders for our skin and hair! I would highly recommend you setting up an appointment to allow Brock to come perform a water test at your home! You would be surprised!”
“The new water system has made my hair and skin softer and healthier! I use less product and I am saving money. A great company and product.”

What's floating in our water supplies? Contaminants commonly found in our waterways.
Surface water from freshwater sources accounts for more than 60 percent of the water delivered to American homes. And according to surveys on national water quality from the U.S. Environmental Protection Agency, nearly half of our rivers and streams and more than one-third of our lakes are polluted and unfit for swimming, fishing, and drinking.

Bromine
This is a chemical disinfectant. High levels in your water lead to throat and eye irritation.
Chlorine
This is found in most city water, as it’s used as a disinfectant during the water treatment process. However, too much chlorine in your water leads to asthma and breathing problems. There are also negative effects if chlorine is combined with other chemicals present in your water. For example, if bromine and chlorine combine, it leads to the chemical creation called trihalomethanes. Ingesting this through your water is linked to cancer.
Nitrates
This chemical enters our water through runoff from septic tanks, sewers, and fertilizers. This can cause thyroid complications of infant blue baby syndrome.
Water Hardness
This affects your skin, hair, and can shorten the lifespan of your appliances. We can test this by adding a solution to your tap water. This solution will respond to the hardness of water through a color change. If water turns pink, then the water is hard. If water turns blue, your water is soft. Hard water can affect your skin, hair, and shorten the lifespan of your appliances.
Precipitate Test
This tests just how hard your water is! For this, we take multiple samples from your home water sources and compare it to our filtered water. We then add a solution that draws out sediment, water impurities, and particulate matter from suspension to be visible. This way you can see exactly what’s in your water sources.
Chromium Test
This is a Nitrate chemical deposited from steel through erosion. Health effects include allergic contact dermatitis or lung cancer.
Heavy Metals Test
We test for heavy metals including lead, mercury, cadmium, and cobalt. Heavy metals attract bacteria, further leading to liver or kidney damage.
Soap Shaker Test
Our final test is seeing how much soap is necessary for your tap water, based on the hardness or softness. Hard water requires more soap to be used, causing you to spend more money every year.

-
Blackcat Resin. Establishes higher capacity to remove iron and hard materials.
The system enhances its overall capabilities by using a catalytic carbon filter instead of the standard coconut shell carbon filter. This guarantees a reduction in chloramine particles, a disinfectant made of ammonia and chlorine that shouldn’t be in our water supply. The system holds a higher capacity for chlorine reduction and can reduce the presence of THMs, VOCs, and Hydrogen Sulfide (rotten egg smell).
The Ranger Series uses a Bacteriostat 55 to aid in chlorine reduction and prevent bacterial growth in the media bed.
