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.

Women are the superheroes of our society, and just like in true superhero-fashion they carry out their work swiftly and efficiently without anyone realizing just how much they do to make sure everyone stays safe and life keeps running! They manage to juggle a variety of tasks everyday and their hard work is often under-appreciated. In lower income countries, women are the ones to grow and produce food, obtain water, cook, clean, bring up children, and take care of the household. However, even though women are awesome, they face unequal health risks compared to men and climate change will only make things worse. Read on to learn more about how climate change impacts women's health specifically.

How women are more vulnerable

Certain cultural and religiously based gender roles place women and girls at higher risk of developing health risks. For example, women suffer from higher rates of anemia and malnutrition compared to men globally (5). In countries with deep-rooted gender norms, women eat last after all the men and boys have been fed and consume the least amount of food (8). Women are usually also the first to sacrifice their own food to ensure their families have enough in periods of crisis (8). All of this contributes to calorie deficiency, chronic energy deficiency, and poor health in women, making them more vulnerable to climate catastrophes (13).

Women are also more economically vulnerable due to lower social and political status in countries with strong gender roles (12). They often don't share the same rights as their male counterparts when it comes to things like social status, land ownership, educational opportunities, and health outcomes as it relates to reproductive and sexual health (12). Since women are responsible for household food and water collection in these countries--both time consuming and physically demanding tasks--they often don't have the time or opportunity to earn an income or continue their education or participate in local governance (12,13). In general, women in these societies have lower average literacy and education levels and even if they are able to secure a job are still regarded as secondary income earners and are the first to be laid off (13). This economic and social insecurity highlights the fact that women are more likely to slip into and live in poverty, inhibiting their ability to adequately provide self-protection and improve their socioeconomic condition (13).

In many societies, women are also in charge of caregiving responsibilities, which could prevent them from leaving certain areas outside their immediate environment (12). This would impede their ability to mobilize in case of emergency or climate disaster (12). Women are also at higher risk of violence during and after disasters (12,13).

It's clear to see from this that women face a number of challenges due to just their gender identity and often suffer more than men from poverty, hunger, malnutrition, economic crises, violence, and disaster related problems (13). Climate change-related disasters have the potential to make things worse.

Climate Change will make things worse

Climate change can impact people's health through a variety of mechanisms—heat, poor air quality, extreme weather events, reduced water quality, decreased food security, and vector-borne diseases, just to name a few (5). Since women have distinct physiologic and health needs throughout their life cycle, especially during periods like pregnancy, this places them at a greater risk of climate change impacts and sensitivities (2,5).

Since climate change can lead to increased temperatures and sea level rise, this contributes to heat waves and saltwater intrusion in rural coastal areas (2, 6). Saltwater intrusion happens when seawater encroaches into fresh groundwater supplies and increases the salt content of people's drinking water (7). This is an issue because people can't drink salt water and it can't be used to irrigate crops, so this could contribute to water scarcity and food insecurity (7). In addition, both saltwater intrusion and heat waves increase the potential risk for pregnant women of developing preeclampsia, gestational hypertension, or delivering preterm (2,6).

Since women often eat last in their families in certain countries, climate-driven food insecurity would worsen their already limited nutritional intake (5,8). This would negatively impact women's health during menstruation, pregnancy, and nursing—all periods of time when women have increased nutritional needs physiologically (2,5). Since women produce around 60-80% of all food in low-income countries and are the main food producers and providers in the world, climate change-related agricultural issues and food scarcity wouldn't just be a health issue but an economic one as well (2,3,5). Women's livelihoods as smallholder farmers would be at risk from climate-related crop failure, which would increase their risk of falling into poverty (5).

During climate-related disasters like floods, storms, droughts, and heat waves, women suffer more mortality cases compared to men and are at a greater risk of experiencing physical, sexual, and domestic violence afterwards (2,5). This mortality difference is most striking when compared to women's socio-economic status in the country, since women have the worst mortality outcomes in countries where they have very low social, economic, and political status (10).

This combination of low social and economic status and socially constructed gender roles contribute to the increased climate change-related health risks women have compared to men (9,13). However, we can do things to change this.

The way forward

Thankfully, organizations are aware of this disparity and have been researching how to mitigate it. By empowering women to participate in decision making at all levels and providing proper access to information and education, we can help develop and improve women's livelihoods and create lasting social change (13). Increasing women's social and economic opportunities will allow them to not only develop more social network connections and have greater autonomy and independence, but also contribute to overall better health outcomes.

While both men and women will be vulnerable to changing environmental conditions, the drivers and effects of climate change are not gender neutral (3). To help address this, women should be included at all levels of decision making so as to contribute to the process of assessing vulnerabilities and capacities and promoting equality (2,5,13).

11 Non-Toxic Deodorants

Natural deodorants that actually work

Switching from a traditional antiperspirant to a non-toxic deodorant can be a little tricky. We have found that patience and a little experimentation are what it takes for a successful switch. In order to find deodorants without synthetic fragrances, aluminum, or other harmful chemicals, we scoured ingredient lists, tried a ton of products, and read reviews to find the 11 best non-toxic, natural deodorants.

Whether you have sensitive skin, want something with a pleasant smell, or want something unscented, we think there is something for everyone on this list! Not all deodorants work well for everyone, and some people prefer different application types. For some people, baking soda irritates the skin, and for others it doesn't. So, if the first one you try isn't working for you, try another one! There are baking soda free natural deodorants and there are some brands that have plastic free deodorant options too! Also, remember, these are deodorants, not antiperspirants, so the focus is on keeping you from smelling more than it is on keeping you from sweating, since sweating an important natural detox mechanism. So give one of these natural deodorants a try and be rest assured that they are better for your health!

What are Period Care Products Made Of?

What you need to know about some concerning ingredients

Because Health: Although being on your period can be a pain (sometimes literally- thanks cramps...), we know period products have got us covered. Even during tricky situations like swimming, athletics, or even wearing white pants, period products like pads, tampons, and menstrual cups are there for us. While they can be a life saver during our period, there's still so much we don't know about the ingredients that are used in these products, or how these exposures might impact our health. There's way too much mystery surrounding a product that we use daily, for hours at a time, that come into contact with some of the most absorbent and sensitive parts of the body, which is why Women's Voices for the Earth (WVE) decided to look at this topic further. Keep reading to hear from WVE about what's in period care products, what regulations are needed, and some safer options that are available now.

What's In Period Care Products?

Most pads and tampons are much more than a simple piece of cotton. Generally, products are made to be super absorbant, comfortable, easy to use, and can have other properties like "odor-absorbing" or some products even provide a scent.

Yet there is still so much we don't know about the ingredients that are used in these products, or how these exposures might impact our health. In fact, the Food and Drug Administration (FDA) considers menstrual products "medical devices" so manufacturers of these products are not required to disclose their ingredients.

Independent, testing from various organizations, media sources and governing bodies from around the world has found numerous chemicals of concern in these products, particularly in chemical additives such as fragrances, lubricants, lotions, odor-absorbing compounds and even antibacterial compounds that are often added to menstrual products by manufacturers. Chemicals linked to allergies, irritation, cancer, endocrine disruption and birth defects have all been found hiding in period care products. In fact, as recently as 2020, phthalates (chemicals widely flagged as harmful) were found in every single sample (of the total 43 pads, panty liners and tampons tested) that were tested!

Once you realize how many questionable chemicals are in so many period products, It's not surprising to learn that the US Food and Drug Administration (FDA) has received hundreds of adverse health reports regarding tampons and pads. They describe genital irritation, rashes, chemical burns, allergic reactions (including anaphylactic shock), toxic shock syndrome and other symptoms as a result of exposure to a menstrual pad, pantyliner or tampon.

What Are the Health Impacts of Chemicals in Period Care Products

These reports and tests have raised important questions about the potential health impacts of these exposures. While a few studies have attempted to assess and measure potential risks of these products, all have indicated that there is more work to be done to better understand the impacts these products may have. What's more, the route of exposure to chemicals from menstrual products is both unique and poorly understood. Chemicals absorbed through the vagina are easily and effectively distributed throughout the body, without being metabolized. In order to better understand the health impacts of chemical exposures from menstrual products — at the very least — we need to know what is in them.

People deserve to know what's in the products they are using! This information is vital to make informed decisions about our health, and what we're putting on and in our bodies. We have come to expect disclosure of ingredients in foods and cosmetics because of the direct interaction of these products with our bodies. We should expect no less from menstrual products.

New Regulations for Menstrual Care

Because of public demand, many companies that make period products have started voluntarily disclosing some ingredients. In addition, many new companies have built ingredient disclosure into their policies and practices, understanding the importance of transparency and safety. However, voluntary disclosure remains problematic as it is inconsistent, is not universal, and these products are not always available or accessible to everyone.

New Right to Know Regulations

Important changes toward transparency are already in the works! In 2019, New York became the first state in the nation to require manufacturers of period care products to disclose ingredients. This new law will go into effect October 2021 require any menstrual products sold in the state to contain a "plain and conspicuous" list of all ingredients, in order of predominance. This must be printed on, or affixed to, the package. There's no doubt that this will have national impact, as it will open up new information about these products than ever before.

On the federal level, Congresswoman Grace Meng, is reintroducing her bill, the Menstrual Products Right to Know Act, which will require disclosure of ingredients in menstrual products, including tampons, pads, menstrual cups and period underwear — providing vital ingredient information for people across the nation.

Safer Period Products Available Right Now

Even though there's a lot of work to be done related to the chemicals found in period products, we're already starting to see positive changes. An increasing amount of non-toxic options available for period products and ways to report negative health impacts means individuals can immediately take to protect their health.

- Choose unscented products where available, especially in tampons and pads.

- Choose chlorine-free bleach or unbleached tampons and pads.

- Organic products are also a good option as they are typically free (or nearly free) of fragrances and pesticides, and often have fewer additives, dyes or bleaches.

- If you are having allergic symptoms, switch brands, and then tell the company why you did by calling the 800 number on the label.

- Report any symptoms possibly resulting from these products to the FDA by calling 1-800-332-1088 or filling out a consumer report form.

- Look for period underwear that is made out of 100% cotton and doesn't use silver

Canned Coffee is Convenient, But What About BPA?

Why they should be a treat instead of part of your daily routine

Now that we're all working from home, it's easy to get bored of our everyday homemade coffee routine. Sometimes we just want something different to wake us up in the morning or even a quick pick me up in the afternoon! That's where canned coffee comes into play. It's quick, convenient, and comes in a ton of flavors. But that convenience might come at a cost; there's been concerns surrounding the use of BPA in the lining of canned products. So, does canned coffee pose a risk to health? We looked at the research to find out.

The Problem With BPA in Cans

BPA, or bisphenol A, is a synthetic chemical that acts like estrogen in our bodies and it has been known to screw with important hormones like testosterone and thyroid hormones. Some of the common health problems associated with BPA include breast cancer, reduced sperm production, obesity, reproductive issues, disruption of brain development and function, and damaging effects to the liver (1). To make matters worse, there is more and more scientific evidence that even very low doses of BPA exposure can be harmful, especially for pregnant women and babies. Low doses of BPA exposure have been tied to abnormal liver function, chronic inflammation of the prostate, cysts on the thyroid and pituitary gland, and many more serious health effects during the early stages of life (5).

Even though BPA is definitely not a chemical we want to be exposed to, it's found basically everywhere, including our food. One common place to find BPA is the internal lining of canned foods or beverages. BPA can help prevent corrosion between the metal and the food or drink inside a can, but over time (or if stored under the wrong conditions like high temperatures), it can start to leach out and get into the food or drink (2). Even cans that say BPA free can have nasty BPA alternatives that have been shown to have similar hormone disrupting effects (7).

Studies have shown that canned soft drinks, beers, and energy drinks all had small traces of BPA in them. Beer was found with the highest concentration of BPA, followed by energy drinks. Soft drinks were found to have the lowest concentration of BPA. In order to find out where BPA in these drinks was coming from, researchers compared the canned drinks to the same drinks packaged in glass bottles. They found very little to no traces of BPA in the glass bottled drinks, which means that the source of BPA in the canned drinks was definitely coming from the cans themselves (2,3,4).

Even if there are only small traces of leachable BPA, it can still be harmful if we are consuming canned products on a regular basis.

Is Canned Coffee Safe?

With the recent increase in popularity of cold brew and other canned coffee drinks, there have not been extensive studies on BPA levels in canned coffee. However, one study of canned coffee drinks in Asia, where they have been popular for longer, did find that BPA was leaching into the coffee from the can. Interestingly, they also found that the more caffeine was in the coffee, the more BPA leached from the can into the drink. Meaning the more caffeine, the more BPA! (4,6) Now before you think you can get away with only drinking decaf canned coffee, keep in mind that caffeine only increases the leaching from the can, but it can still happen without it (6).

Even though the levels of BPA found in canned coffee were relatively small, because BPA is all around us in so many common products, we should try to limit our exposure as much as we can. This means that it's probably okay to drink a canned coffee every once in a while, but best practice is to not drink them every day. But if you're in the middle of a road trip and are desperate for some energy, don't get too stressed about grabbing a canned coffee!

Canned Coffee Alternatives

If you're starting to get worried about what coffee to buy when you're out and about or when you want something more than just plain coffee, don't stress! We thought of some easy and fun alternatives for your canned coffee fix that might make you forget all about it!

  1. Swap out the canned coffee for coffee in a glass bottle or tetrapaks whenever possible.
  2. Find some fun new ways to make coffee at home like using a Chemex or a nice French press!
  3. Go get a coffee at your local coffee shop. Support small businesses if you can!
  4. If you like canned coffee because of the flavors, try making your own caramel or mocha sauce at home. It's pretty easy and it saves money! For something icy and refreshing, we are partial to muddling some fresh mint with some cold brew.
