What kind of water-filter do I need?

To remove contaminants most household systems, utilize a combination of carbon and a fine filter. Contaminants become trapped on the surface or in the holes of the filter, passing the clean water through to the tap. Typically, the water going into Reverse Osmosis systems will be pretreated by these filters before being irradiated with UV.

When choosing the best water filter to suit your needs, determine your needs and desired outcome.
For example, is it to remove the chlorine taste, filter out heavy metals, or screen out silt?
To meet the varied needs of the typical consumer, a variety of affordable filters are made. These include refrigerator filters, faucet mounted filters, pitchers, under sink filters, and showerhead filters.

It’s important to understand not all filters are equivalent in form or functionality, however there are standard ratings across all certified water filters, and that will help you choose which filter may be best for you.
