There’s a lot more in your water than just hydrogen and oxygen. From chemicals to minerals to bacteria, the tap water in your home could potentially contain unwanted substances.

There are various ways to clean your water with different kinds of water filtration systems. Let’s take a look at what’s best for certain areas of your house as well as the price ranges of the different options available. The benefits of water filtration extend beyond drinking water.

Whole-House Water Filters

Chlorine is added to public drinking water to kill bacteria, but studies have shown that prolonged exposure to chlorine itself can have harmful effects on humans. Since it’s already in the water when it reaches your home, it’s up to you to get rid of it and other contaminants before they reach your body. Whole-house water filters catch the water at the point of entry before it reaches your pipes. They range in price from a DIY basic filter around $50 up to $1,000 and can reduce the harmful effects of chlorine and other chemicals, as well as removing particles that can cause build up in your pipes across your entire home.

Water Softeners

Water softeners are a way to treat “hard water,” which is water filled with minerals such as calcium and magnesium. Hard water can cause these minerals to build up not only in pipes but also in water heaters, coffee machines, dish washers, etc. Water softeners will allow these appliances to last longer and will improve their efficiency. Soap and detergents work better with soft water. They are typically beneficial if your home uses well water. Water softeners range in price from a couple hundred dollars up to about $600.

UV Water Purification Systems

UV water filters use ultraviolet light to purify water, which is the same technology used by many bottled water companies. The ultraviolet lamp creates short-wave radiation that kills bacteria and viruses. This is another great option if you use well water since UV purifiers do a great job without having to add chlorine. These can be picked up for about $400.

Reverse Osmosis Filters

Reverse osmosis filters are installed under your sink and cut down on contaminants such as lead, arsenic and ammonia and chemicals like fluoride and chlorine. These run for about $150 a piece.
