Water is necessary for cooking, cleaning, bathing, and drinking. To be certain the water from your tap is safe, have a professional test your water. With a clear idea of any contaminants, you can make an informed decision about the home water filter that will best meet your needs.
Home Water Filters Serve Different Purposes
Order a water test to learn about any contaminants since home water filters are designed to filter out specific materials. For example, one type of filter may be great at removing dirt and debris, but it may not filter out bacteria or viruses.
The following list describes the most common home water filters used today.
Activated Carbon Home Water Filter
Activated carbon filters are the most popular type of home water filter available. These types of filters are small, simple to use, inexpensive, and easy to replace. Activated carbon filters effectively remove most contaminants except for limescale, nitrates, fluoride, sodium, and microbes.
Activated carbon filters work by using the molecular structure of charcoal. The various ridges and pores throughout the charcoal trap contaminants. This process is called absorption and is why charcoal filters need to be replaced often to remain effective.
Distillation as a Water Purification Option
The idea behind this method of filtering water is that water vapor carries little to no contaminants. The water vapor becomes trapped within a separate container to be condensed back into drinking water.
Water boils at lower temperatures than most contaminants. This means that contaminants will stay in the original container while your water is filtered and stored elsewhere. There are some contaminants that boil before water does, so some chemicals do transfer into the filtered water. The distillation method will also filter out most of the healthy vitamins and minerals in your water.
Instead of just using one method of filtering, reverse osmosis filters utilize five or more types of filters in one device. The first filter acts to block out larger detritus like debris and rust. This is usually followed by two carbon filters of differing densities to capture contaminants. The fourth is the reverse osmosis filter, a membrane that blocks anything small enough to make it through the previous filters. The final filter, most often a UV light, is meant to destroy any bacteria or living organisms.
