There’s no need to tiptoe around your tap—your drinking water is probably safe as it is. Although tap water can contain contaminants, the amounts are usually small and not harmful. That’s because public water systems are required by law to curb these contaminants. Still, you may be among those who choose to fill up with filtered water. Filtering can improve water’s taste and cut extra contaminants.

Many kinds of filters are available. Some attach to the faucet and filter water as it pours through the tap. Some are fitted under the sink, while others are installed where the water line enters the house. Portable pitchers that filter water are another option.

How Filters Work
Water filters work in different ways. Here are some varieties of water filtration systems:

• Carbon filters absorb natural elements in water that can cause a bad taste or smell. They may remove pesticides and chlorine but not lead, copper, and other metals.
• Ion exchange filters soften water and remove metals and minerals.
• Distillation boils water and condenses it to remove bacteria, viruses, and metals. However, it can leave behind pesticides and some other contaminants.
• Reverse osmosis generally cleans out more contaminants than other methods. These units can remove viruses, bacteria, sodium, and other elements. But the price tag may dampen your enthusiasm.

Most filters in portable pitchers work using ion exchange and carbon filters. Unfortunately, no single water filter can remove all kinds of impurities.

What to Know Before You Buy
A product’s claims can be a lot to swallow. If you’re shopping for a water filter, read the product label carefully so you know what you are buying.

Many, but not all, water filters remove Cryptosporidium, a parasite found in lakes and rivers that can cause diarrhea, nausea, and stomach cramps. It can even be deadly to people with weak immune systems. National Sanitation Foundation (NSF) International tests filters to see if they remove this bug. Look for filters marked with the NSF trademark and the words “cyst reduction” or “cyst removal.”

If you buy a filtration unit, change the filter as often as the label says. Otherwise, germs and other contaminants can build up in filters. Consider wearing gloves when changing filters, and wash your hands afterward. If you have a weak immune system, ask someone else to swap filters for you.

Protect your drinking water by recycling used motor oil, even if it’s just a pint. If you let it drain in a sewer or toss it in the trash, it can leak into water sources.
