Are faucet water filters worth it?

The short answer is yes as long as you buy the best one! Water filters serve as a middle ground between contaminated and fresh, pure water. And you’re probably already well aware of the detrimental effects harsh chemicals when consumed can have on your overall health, so getting a water filter especially since they’re highly affordable is a wise and healthy addition to your kitchen.

Should you filter tap water?

Tap water is generally safe to drink, but not free from contaminants and impurities that may affect your long-term health. By adding a filter to your faucet, you also gain instant access to odorless water, and save bucketloads of cash spent on buying plastic bottles.

What chemicals are added to tap water?

Lead is found in large traces in tap water, and tends to leach from lead pipes and plumbing fixtures. It can cause adverse health effects in adults, and neurological and behavioral problems in children. Other chemicals detected in tap water are arsenic, nitrates, atrazine, and pathogens such as viruses, bacteria and parasites.

Tap water in certain areas may also contain radioactive elements naturally, and exposure can cause cancer or kidney failure. Unused medicines when flushed down the toilet can also make their way to the environment, and gradually to your stream of tap water.
