Water Filtration Systems Pros and Cons

Water Filtration Systems Pros and Cons

Each type of water filtration system comes with its own unique pros and cons. Susan Brady broke down some popular filtration systems to help us have a better understanding of which option might be best. 

Reverse Osmosis Filter

This type of filter works by filtering water through a semipermeable membrane. It is an effective method for removing many toxic minerals, chemicals, pesticides and radioactive particles from drinking water. However, this type of filtering also removes many beneficial minerals from the water and can lower the pH. Critics claim that drinking de-mineralized water may increase the risk of osteoporosis, joint conditions and cardiovascular disease. Many companies now sell re-mineralization filters that put minerals back in and raise the pH. You can also restructure the water with trace elements through small amounts of unprocessed salt or by adding liquid minerals to the water.

Granular Carbon and Carbon Block Filters

As per Dr. Mercola: These are the most common types of counter top and under counter water filters.

Granular carbon filters and carbon block systems perform the same process of contaminant removal, adsorption, which is the chemical or physical bond of a contaminant to the surface of the filter media.

Granular activated carbon is recognized by the EPA as the best available technology for the removal of organic chemicals like herbicides, pesticides and industrial chemicals. However, one of the downfalls of granular carbon filters is that the loose material inside can channel–the water creates pathways through the carbon material, escaping filtering.

Carbon block filters offer the same superior filtering ability but are compressed with the carbon medium in a solid form. This eliminates channeling and gives the ability to precisely combine multiple media in a sub-micron filter cartridge. By combining different media, the ability to selectively remove a wide range of contaminants can be achieved. Carbon filters leave in all the minerals, including the highly toxic and radioactive ones.

Alkaline Water Ionizers

Alkaline ionized water is created by water ionizers in a process called water electrolysis. This process occurs inside the electrolysis chamber of the water ionizer machine. Through this process, the water gains more active hydrogen molecules allowing it to act as a strong and effective antioxidant. Proponents of alkaline ionized water claim that this type of water provides a number of important health benefits, as well as better hydration.

There are some research studies to support health benefits such as improving blood sugar control in diabetics and slowing the growth of tumors.

However, critics suggest that alkaline ionizers do not adequately filter your water and can actually increase the pH up to 12 or 13, which isn’t healthy either.

What do you think about Kangen ionized water?

Here is what consumer reports says about Kangen.
