Does reverse osmosis remove pharmaceuticals from water? The answer to that questions depends. And even if it does, is it still ideal for home use?
A reverse osmosis system alone will not remove pharmaceuticals from water. These systems place water under pressure to a semi permeable membrane with a fine pore structure. And since pharmaceuticals are molecularly smaller than water is, they are allowed to pass through the membrane along with some of the water.
However, when used with a quality carbon filter, most prescription drugs can be removed from water. An activated carbon filter gives these contaminants a charge so they are absorbed and removed.
But even if a reverse osmosis system does remove pharmaceuticals from water, should you really be using them in your home, especially for drinking purposes?
The biggest problem with reverse osmosis systems is the fact they they remove all the healthy and beneficial minerals that our body needs on a regular basis. Minerals like iron, calcium, sodium, magnesium, and potassium are all naturally found in water.
Many experts are now saying that drinking demineralized water over the long run can increase your risk of mineral deficiencies and even cancer. Since demineralized water is more acidic than alkaline, minerals have to be pulled from your teeth and bones to neutralize the fluid. This also increases free radical production in your body, which leaves you more prone to cancer.
So is using a reverse osmosis system the best way necessarily to remove pharmaceuticals from water? Probably not....
You're better off using a multi-stage filter that's effective at removing synthetic and volatile organic chemicals (SOCs) and (VOCs) while keeping trace minerals in the water. These are the general categories that most prescription drugs fall under.
If you're looking for a quality home filter system at a very affordable price, then I suggest getting the system my family and I use in our home. It filters out more than 99% of most contaminants (including prescription drugs) and it only costs 0. And with factoring in the replacement filter cost and how long each lasts, it only costs 9 cents to filter a whole gallon of tap water. But what's most important is that we know it's safe and healthy to drink.
