Are Plastic Water Filter Pitchers Ok to Use?

Making sure your drinking water is healthy and safe

Water filter pitchers are a commonplace household item that almost everyone has. These handy devices magically turn our tap water into crisp, fresh mountain spring water. Okay, that may be a slight exaggeration, but it does make it taste better! Since many water filter pitchers are made from plastic, we decided to take a look at how healthy and safe they are when compared to alternatives such as tap water and bottled water. Let's dive in!

First, to better understand the use and necessity of water filter pitchers, we need to understand their purpose. The main use for most at-home water filters is to change and enhance the taste, color, and smell of drinking water, thereby improving the water's aesthetic effects (1, 2). The EPA has established both primary and secondary National Drinking Water Regulations meant to protect the public against consumption of drinking water contaminants that pose a risk to human health (2). Primary Standards are federally-enforced mandatory water quality standards, while Secondary Standards are non-mandatory water quality standards established as a guideline to assist public water systems in managing the aesthetic considerations for drinking water like taste, color, and odor (2). In some households, however, water filters are a necessity. Water from wells, older pipes, and other external factors can negatively impact water quality even with EPA regulations in place.

So, What Do Water Pitchers Filter Out?

When looking at different water filter pitchers, it is important to check their certifications. Certification is important because it shows the product has been verified by an independent third party to do what it says it does (3). Most commercial plastic water filter pitchers are certified by either the NSF/ANSI (National Sanitation Foundation/American National Standards Institute), the WQA (Water Quality Association), or both (4). However, even among certain certifications there are different standards they can be certified with. For example, water filters certified by NSF/ANSI can be either standard 42 or standard 53 (3, 5). NSF/ANSI standard 42 focuses on the aesthetic effects of drinking water treatment and establishes minimum requirements for systems designed to reduce non-health-related contaminants (5). NSF/ANSI standard 53 focuses on the health effects of drinking water treatment and establishes minimum requirements for systems designed to reduce specific health-related contaminants (5). NSF/ANSI standard 42 reduces contaminants like chlorine, taste and odor issues, chloramine, particulates, iron, manganese, zinc, and total dissolved solids (TDS) in drinking water, whereas NSF/ANSI standard 53 reduces contaminants like heavy metals (lead, arsenic, cadmium, chromium, copper, mercury, and selenium), cryptosporidium, giardia, inorganic compounds, and volatile organic compounds (VOCs) in water (3, 5). Since PFOA/PFOS--fluorinated organic chemicals that are part of a larger group of chemicals known as PFAS--are also a concern for people, the NSF has a P473 standard for that as well (19, 20, 21, 22).

Table created from information from [3], [5], and [21].

If you are looking for filters that can remove specific contaminants in your drinking water, make sure to check the product's NSF/ANSI standard certification beforehand. While most water filter pitchers are able to remove contaminants that affect the taste of water like chlorine, zinc, and hydrogen sulfide, not all are able to filter out contaminants like heavy metals and VOCs (8). Because of this, it's important to know what's in your water. You can check your community water system quality reports at the EPA Federal Reports site here, which also shows you potential water system violations. If your drinking water contains serious contaminants like lead or other heavy metals, it's advised to install a more comprehensive filtration system in your house or apartment (8).

Are Plastic Water Pitchers Bad?

Most water filter pitchers are made out of hard clear plastic, and popular brands advertise that their pitchers are BPA free. For example, according to Brita, their pitcher lids and filter housings are made out of polypropylene plastic, the reservoirs and pitchers are made from either NAS (a styrene based plastic) or SAN (styrene acrylonitrile), and all are tested by the NSF for material safety (12). However, there have been several studies that show that many hard clear plastics, including BPA replacements, do release estrogenic chemicals (23, 24, 25, 26). Plastics and endocrine disruption are still being studied, so erring on the side of safety, here are a couple of suggestions to help you properly take care of your water filter pitcher.

Tips for properly taking care of plastic water filters

  • Hand wash plastic components with a mild detergent and air dry upside down; make sure to not use any abrasive cleaners. Hand wash only, since the heat from dishwashers can stress the plastic over time.
  • Store filled pitchers in a cool, dim place away from sunlight to prevent algae formation. Both heat and UV light are shown to increase leaching from plastic, so it's safer to store your pitcher in the refrigerator or away from windows.
  • If you go on vacation and water has been left in the pitcher for a long time, it's a good idea to dump that water, give the pitcher a wash, and then refill it. Time of contact increases the potential of leaching from plastic, and standing water increases the risk of other contaminants building up.
  • Regularly replace filters for optimal performance depending on guidelines; most standard filters recommend replacement every 40 gallons, which is approximately every two months. Bacteria build up in the water filters themselves, so it is important to do this.

What If I Don't Want a Plastic Pitcher?

If you would prefer to not use a plastic water pitcher, no worries! There are glass and steel pitchers as well, although options are limited. It should be noted that most water filters do contain some plastic, even if the pitchers themselves are a different material. There are also water filters that screw onto the tap and countertop water filters that attach to taps that have less plastic. If you want to ditch the plastic pitcher completely, you can invest in a whole house filter or an under-the-counter reverse osmosis system.

Sustainability of Single-Use Filters

Since water filters need to be replaced on a regular schedule, you might be wondering what to do with the filter itself, which is usually housed in plastic. Many water filter companies have recycling programs, so you can look to see if there is a recycling component for your used water filters. For example, Brita currently partners with TerraCycle to offer a free mail-in recycling program for Brita filters, pitchers, dispensers, bottles, faucet systems, and packaging (14).

Make sure to not throw the filter directly into your municipal recycling bin as it can contaminate the recycling stream. It is also not recommended to cut open the filter to separate the plastic from the filter media inside. While the filters are made out of less plastic than bottled water, they are not a plastic-free solution.

Other Alternatives?

Popular alternatives to filtered water include tap water and bottled water. The EPA has established protective drinking water standards for more than 90 contaminants as part of its comprehensive Safe Drinking Water Act (SDWA), although there are still incidences where violations occur (16). Bottled water also presents various health hazards, so it should not be regarded as the de facto standard either. The plastic of bottled water is made from PET, a material regarded as safe for one-time use, but refilling bottles or storing them in hot places increases the risk of chemicals and microplastics leaching into the water (1, 17). The bottled water industry is also self-regulating and not always liable to FDA regulations, so there's a greater chance of contamination occurring (1, 17). Recent tests have actually found PFAS and arsenic in bottled water for sale (27, 28). Bottled water also has a huge environmental impact, since 86% of all plastic water bottles end up in landfills rather than being recycled (18).

Final Take-Aways

Plastic water filters are helpful tools that allow individuals to enhance and improve the taste and smell of their drinking water, as well as remove potentially harmful chemical contaminants. While we work to create better water filtration systems within our communities, plastic water filters are a good alternative for people's current drinking needs.

Why does your activewear stink and what can you do about it?

The scientific reason behind your bad smelling activewear and easy DIY solutions

Do you ever take your laundry out of the dryer and realize that your activewear still smells bad? Sometimes it feels like no amount of laundry detergent or scented fabric softener will get rid of that funky smell that lingers in all of your workout clothes. The reason this happens isn't because your washing machine isn't strong enough to get rid of the sweat from your run or all the burpees you did, but it's actually the fabric. Most workout clothes are made from synthetic fabrics or cotton, two materials that are great for working out in, but really bad at getting clean. Luckily there are a few ways to get rid of that smell that doesn't involve lots of harmful chemicals. So instead of throwing those smelly clothes away, check out some of our easy non-toxic cleaning methods and DIY solutions!

Why do workout clothes trap smell?

Most people think that the reason their workout clothes stink is because there is sweat trapped in them, but that is only partially true. Sweat by itself actually has no smell at all, but when it comes into contact with the bacteria on your skin, the sweat gets broken down and releases the typical body odor smell (1). So that means there isn't excess sweat trapped in your clothes, it's bacteria, along with dead skin cells and natural particles that are all contributing to the bad smell (2).

There is also a difference in how natural and synthetic workout clothes are affected by this bacteria. Natural fibers like cotton are more affected by sweat and bacteria compared to synthetic fibers because the bacteria that becomes trapped within the fabric can actually start to break down and degrade your clothes. The fibers of cotton are made completely of cellulose, a natural component of plants, and the bacteria can consume this substance and break down the clothes. Cotton is really good at absorbing sweat, so that means there is bacteria deep inside the cotton fibers and the bacteria can quickly multiply due to their massive food source i.e. your clothes. So not only will the bacteria in your sweat make your natural workout clothes smell bad, it will also degrade them over time until they fall apart (2).

Synthetic fabrics, on the other hand, are man-made fibers that are derived from petroleum products. Think plastic threads. Fabrics like spandex, polyester, and nylon are all made of synthetic materials and they are often marketed as sweat wicking or having a cooling effect. These types of fabrics collect bacteria in the space between the fibers, but does not absorb the sweat or bacteria in the fibers. These small spaces where the bacteria are trapped are really hard to access with standard cleaning products making the smell linger (2).

What makes it worse?

To get rid of the smell a lot of people use more detergent or heavily scented fabric softeners, but this only temporarily covers up the smell. These products coat the fibers and fill up the space between them, creating more and more build up the more you wash the clothes. Having build up on your clothes can trap the bacteria and every time you work out more bacteria will start to grow on your clothes.

Traditional detergents were made for traditional fibers like cotton, so when trying to get spandex or polyester fabrics clean, these detergents often aren't strong enough to penetrate deep into the synthetic fabric. Also sometimes your washing machine might be too big or too full and isn't able to clean the clothes effectively. The good news is that there are some non-toxic products and DIY methods that will really deep clean your clothes and make them smell brand new!

What can you do?

First things first, before you get into the products and DIY solutions, try some of these simple ways to avoid having stinky workout clothes in the first place. Sometimes all it takes is changing the temperature or washing your clothes a little sooner. But if none of these work, check out the special products and DIY solutions that are sure to get your clothes squeaky clean!

  1. Don't overfill your washing machine.
  2. Don't use extra laundry detergent.
  3. Stay away from fabric softener.
  4. Wash clothes as soon as possible after working out, don't let them sit wet.
  5. Always wash workout clothes in cold water.
  6. Use a powdered detergent to prevent buildup.

Healthy eating should be about more than just healthy ingredients! While there are many different specific diets, most definitions of healthy eating involve choosing fresh, nutrient-dense whole foods that provide maximal nutritional benefits. Refined grains, sugar, vegetable oils, and other unhealthy ingredients are left off the plate. But if healthy ingredients become contaminated with harmful chemicals, are they really healthy? It is time for healthy eating to incorporate more than just ingredients. Healthy eating should also include how the food is packaged and what materials the food comes into contact with while it is being processed, cooked, and stored.
