Are Reverse Osmosis Water Filters a Good Choice for Your Home?

Although reverse osmosis water filters are a common household filtration device today, they weren’t originally created for the home. Originally, this type of filtration device was designed for industrial and commercial usage. Reverse osmosis water filters have been used successfully in commercial applications,especially in removing salt from salt water.

Reverse osmosis water filter systems work with large amounts of water. This fact makes it a good fit for industrial and commercial usage but not a good choice for your home. Reverse osmosis systems use a semi-permeable membrane to separate contaminants from water. Water can pass through the membrane but contaminants cannot. When different contaminants are caught by the membrane, water pushes any impurities found on the membrane in the opposite direction than the purified water flows.

Reverse osmosis water filters use a larger amount of water than any other water filtration system. This design of water filter wastes three gallons of water as it purifies one gallon of water. The filter uses technology called back flushing. This is when water is used to flush out contaminants. Only 5 to 15% of the water that is actually used comes into your home. The rest is used in the filtration process.

The main reason that a reverse osmosis water filter isn’t a good choice for your home is that it doesn’t remove all contaminants. This type of device is only designed to remove contaminants that are the same size or bigger than the water molecule. Unfortunately, some of the most deadly contaminants like pesticides, bacteria, and chlorine are lighter than water.

Reverse osmosis water filters also remove healthy minerals that can be found in your drinking water. The process of purifying the water strips away trace minerals that benefit you and your family’s health. This process can be more harmful than the condition of the water before it was treated by a reverse water filter because when the water is demineralized, it opens the door for contaminants to attack your body. Some health risks if this approach to water purification is used could include cancer, neurodegenerative disease, and much more.

Reverse osmosis water filters advertise that they are great devices for residential use. This isn’t true. There are wide varieties of filtration devices that work better than reverse osmosis water filters. For example, ion exchange filters soften hard water. They can also remove more lead than reverse osmosis filters can. Ultraviolet radiation treatment kills more bacteria and microorganisms. Of all of these approaches to water filtration, the one that is the most efficient, however, is a carbon water filter.

Carbon filter devices are becoming more popular because they are efficient, easy to install and maintain, and economical. There are different types of carbon water filters that are designed to attach to your water supply entrance or kitchen faucets or even be used as a portable water pitcher filter.

With a carbon water filter, the healthy minerals are not removed from the water. Aquasana has filters for every area in your home that you could need.
