Is there really plastic in my water? A co-worker has a lamp on her desk that she says kills germs. I looked into getting one, but they’re expensive! Is it worth the splurge?

Q:

I got concerned when I read that most of the water we drink contains tiny plastic particles. Is that dangerous for my health, and is there anything I can do to reduce my exposure?

A:

Since tiny plastic particles in our water, called microplastics, have only become an issue in the past few decades, there’s not much conclusive research on the long-term effects of consuming them. But to be safe, it’s best to try and avoid the microscopic particles, which are found in 94% of bottled and tap water, whenever possible. Some studies suggest that the plastics may impact our health by causing metabolic issues, disrupting hormone balance and weakening immunity. Thankfully, using a filter can ensure that your drinking water is free of any of these particles and is safe for your health.

I suggest opting for a membrane filter pitcher, like LifeStraw Home (LifeStraw.com), or a carbon filter, like FloWater faucet filter (DrinkFlo Water.com). These filters are the most effective at removing the majority of impurities, including microplastics, from drinking water. Plus, they’re easy to use, and they can last two to three months before a replacement is needed. Bonus: These types of water filters will also remove pesticides, bacteria and parasites that can be harmful to your health.

You may also be exposed to microplastics from plastic food-storage containers. In fact, Irish researchers have found that when heated, these containers can leach thousands of microplastic particles into your food. But it’s easy to limit your exposure to those particles: Simply avoid microwaving plastic, store food in glass or silicone containers and purchase salad dressings and sauces in glass bottles instead of plastic.

QAWhile these germ-killing lamps have become increasingly popular, I don’t recommend them. They’re touted for eliminating bacteria and viruses, thanks to the ultraviolet radiation they give off, but the lamps that are commercially available don’t actually produce enough radiation to kill the germs—and stronger lamps can damage skin.

A better option that will save you some money too: Stock up on alcohol wipes or a disinfectant containing the antibacterial compound ammonium chloride (it’ll include this ingredient on the label), like Lysol Disinfecting Wipes. This means the wipes are study-proven to kill illness-causing bugs. You can use them to clean high-touch areas and items, like doorknobs, phones and stair railings—a practice I advise doing throughout the day during sick season.
