What Contaminants Can Water Treatment Systems Remove?
It’s practically impossible for just one water filter to remove all of the contaminants in water. For a water treatment system to produce safe drinking water, it’d need to use several filtration methods. The water treatment experts at RainSoft® of NE Iowa give you an overview of the different filter types and the contaminants they can remove below.

Physical Filters
Most filtration systems will use some kind of physical filter to remove dirt, silt, sand, and other sediments.
Active or Chemical Filters
A standard water filtration system will then need to rely on a chemical filter to remove the smaller particles that passed through the physical filter. The term is a bit misleading though—chemical filters don’t introduce chemicals to treat the water. Rather, they’ve been treated to trigger a reaction in chemicals and other contaminants, making it easier to physically trap and separate them from water.
Carbon Filters
The Environmental Protection Agency estimates that a fifth of the country’s water supply contains VOCs, which can pose a health risk depending on the amount present. VOCs are not normally found in bodies of water—traces of VOCs indicates that the water source has been contaminated by residential and commercial products, like gasoline, solvents, cleaners and degreasers, paints, inks and dyes, and pesticides. Carbon filters are quite effective in removing VOCs from water.
Oxidizing Filters
It’s not uncommon to find traces of chlorine in tap water, given that most municipal water treatment plants use it to disinfect the local water supply. If tap water tastes or smells bad, it might have traces of chlorine. Aside from organic compounds, granular activated carbon filters can also trap chlorine.
If you’re having trouble picking a water treatment system, consult one of your local water purification equipment providers.

Our Testimonials
We live a considerable distance away from the city where Rain Soft is located but have never had any problems with the system itself. We were proud to recommend it to our son when he brought the place from us. He has no problems as of this date. Thank you for your service!
Rainsoft is a great product that comes with great service. We feel it was an investment, but we feel it was worth it. We have the Ultrefiner Drinking Water System that we use for all of of water bottles on the go - they stay clean - no yellow or pink film…. The Water Conditioning System is efficient and we used about 6 bags of salt in the last year - active family of 2 with family stopping in. Would highly recommend Rainsoft.
We have been with Rain soft since 1999. We recently purchased a new softener and decided to stay with Rain soft because of their excellent service and quality of product. We have had the reverse osmosis system since the beginning and have also added the chlorine removal tank. We enjoy having the quality water that our system provides us with. Thanks to rain soft. Brent and Carla Whitlock.
Will make this short. Had some problem with our water softener. Had water on the floor. It would make all kinds of noise and the our water softness was inconsistent. Lucas came and took the time to fix it right! Our water softener has never worked this well. Be sure to let Lucas know much we appreciated his work!!
RainSoft has delivered excellent service and products since we installed a whole house water system more than 20 years ago. We recently replaced our refrigerator and RainSoft came the next day to connect the new water line for our ice/water. Prompt and friendly service!
Blake was awesome and the warranty on the products is very good. Blake took the time to replace all potential problem parts in the system at no additional charge. Living in the country with well water is hard on the system but I don’t know what I would do without it. Blake also had some extra bags of salt on hand to save us a trip. Very professional and obviously took pride in doing things right!
