Filters That Remove PFOS So Your Home Drinking Water Is Safer

There is growing concern over the quality of the water supply due to the amount of chemicals that are released into the environment each year. PFOS, or perfluorooctane sulfonate, is one chemical causing concern. It is released from industrial and military sources. It also enters the environment from food packaging materials, fabrics, and carpeting. This chemical, along with many others, is being found in many water supplies and in the blood of people tested for it. Methods are being tested to find ways to remove it from the water since common municipal treatments aren't very effective. Here are some ways to purify water to get rid of PFOS so you can feel more confident about the water you drink.

Reverse Osmosis System For Your Sink

Reverse osmosis systems are found to be effective at removing this chemical, along with many other contaminants. The drawback of reverse osmosis is that it is an expensive water treatment and it wastes a lot of water. It is most practical for treating water at the point of use such as on home faucets and in commercial water dispensing machines.

A reverse osmosis machine forces water through a membrane. The membrane allows water molecules to pass through, but it blocks PFOS and other contaminants. If you want to treat water in your home, you can install a reverse osmosis system under your kitchen sink so it is out of sight.

Ion-Exchange Filters With Activated Carbon

You can attach an ion-exchange filter to your kitchen sink, too. It can be hooked onto the end of your faucet so the water you use for drinking and cooking your meals is free from many chemicals, heavy metals, and organisms. If you want to buy a countertop water filter, check that the filter is certified to remove PFOS. Any quality filter you buy lists the contaminates it is capable of removing. You can also check for third-party verification that testing has been done and found the filters effective.

To keep the filters in good working order, you must change the filters according to the manufacturer's directions. Activated carbon filters are often added to ion-exchange and reverse osmosis filters to remove odors and bad taste from water. Bituminous carbon and coconut shell carbon filters have also been found to reduce the levels of PFOS in water.

Granular activated carbon can also be used on a much wider scale to treat municipal water supplies as well as wastewater. You can test the water from your tap to determine the state of your municipal or well water supply. You may also be able to obtain water testing reports from your water company or city. Installing your own water filter or PFOS treatment system may give you the most peace of mind since it will ensure you'll have the purest water possible for drinking and cooking.
