Making sure your drinking water is healthy and safe

Are Plastic Water Filter Pitchers Ok to Use?

Food

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.

The Best Water Filters

These easy to install filters are perfect for renters or homeowners!

Sometimes we take tap water for granted. If it comes out of our tap it has to be safe, right? Unfortunately, that's often not the case. While our water treatment plants do a great job filtering out the obviously toxic stuff, harmful chemicals like lead, pesticides, PFAS, and pharmaceuticals can still make their way into our tap water. That's why we always recommend a water filtration system! If you're a homeowner, you can install a filtration that integrates with your own water throughout your house.

There are also a ton of great options if you're renting or can't install anything in your home. A small water filter pitcher or countertop dispenser are great options if you're looking for something hassle free. If you're feeling a little more crafty, you can install a faucet mount. These mounts require no tools and can easily install on most faucets!

These water filters are all meet NSF standards and remove dozens of contaminants.

What's the Healthiest Sparkling Water?

We're hooked on flavored sparkling water.... But what are we really drinking?

Let's be real: sometimes we reach for sparkling water to make everyday life feel just a little bit swankier. We also do it for our health. For those of us who struggle with drinking enough water, it's refreshing bubbles and flavors are an enjoyable incentive to hydrate. And since sweetened beverages, like traditional sodas, contribute to chronic conditions like diabetes (1), sparkling water offers a satisfying CDC-recommended substitute for sugary drinks (2). Sparkling water is basically H2O with jazz hands, so there's no way it can be bad, right? As it turns out, there are a few things to watch out for. We're diving deep with sparkling water to help support your health and environment (and your bubble habit).

Let's Talk About Natural and Artificial Flavors...

You've probably seen common ingredients like fruit juice, natural flavors, or artificial flavors in your favorite fizzy water brands. Fruit juice is pretty self-explanatory, but what do we know about the rest?

Natural flavors. According to the FDA, a natural flavor must come from non-synthetic source, such as spices, fruits or vegetables (3). However, the rest of the solution carrying the flavor may still contain synthetic additives as preservatives or solvents (which just means substances used to dissolve other things). These additives like propylene glycol are considered "Generally Recognized as Safe" by the FDA, and some like ethyl formate form naturally in plants (5). But safety studies are ongoing for some of these approved chemicals. For example, recent research has shown methyl paraben acts as an endocrine disruptor in mice and contributes to obesity (6). Organic products have higher standards for natural flavors – the National Organic Program only allows natural flavors if "not produced using synthetic solvents and carrier systems or any artificial preservatives" (7). Organic flavors must be used in organic products if commercially available (7) and comply with USDA organic regulations – including that 95% of the flavor must be certified organic (8).

Artificial flavors. Yep, you guessed it – unlike natural flavors, artificial flavors need not derive directly from natural sources like those listed above (3). Instead they are chemically synthesized. This doesn't actually mean that the main flavor's chemical structure differs from that of the natural flavor. As University of Minnesota food science professor Gary Reineccius explains, "there is little substantive difference in the chemical compositions of natural and artificial flavorings…the distinction in flavorings comes from the source of these identical chemicals" (9). But the kicker again comes from the additional synthetic chemicals allowed to accompany the flavor. Some of these originally occur in nature (such as butyl phenylacetate, found in fruits), while others are totally synthetic and potentially problematic (like phenylethyl benzoate, which is "toxic to aquatic life with long lasting effects.")

Bonus round: what is "naturally essenced"? This is its own category used in particular by LaCroix products. Its true meaning is still unknown, as LaCroix has not disclosed this information publicly. What we do know, according to their website, is that "all LaCroix flavors are derived from the natural essence oils extracted from the named fruit...there are no sugars or artificial ingredients." Furthermore, Business Insider clarifies that "essence is created by heating items such as fruit and vegetable skins, rinds, and remnants at high temperatures, producing vapors. These vapors are condensed and then sold by the barrel."

Bottom line: though natural and artificial flavors are chemically similar, they both come with long lists of potential additives that may be detrimental to our health and environment . When in doubt, stick with what you know is good – like real fruit juice – or opt for brands with organic ingredients and flavors.

How to Sparkle from the Inside Out

Sparkling water containers matter just as much for our health and environment as the inside ingredients. The lining of aluminium cans contain BPA and similar chemicals that are known endocrine disruptors with the potential to cause hormonal and reproductive harm. While these chemicals are less likely to leach into beverages like sparkling water than more acidic beverages, we don't like to make a habit of drinking from cans. Sparkling water beverages also often come in plastic. Microplastics can also end up with your bubbles – a study in 2018 showed that microplastics contaminated 93% of plastic water bottles (10). The research world is still seeking to understand the health implications of microplastics, but given what we already know, we say it's better to play it safe and avoid plastic bottles as much as possible in the meantime. Reducing plastic use is even more important for environmental health now that international governments have stopped buying recycling products from the US (cities in the US are throwing away formerly recyclable types of plastic because they can't afford to recycle, as reported by The Atlantic). Your choice of carbonated beverage is that much better for our health and environment when it doesn't come with plastic!

Simple Solutions for Keeping Your Sparkle Alive

1) Choose glass over plastic containers if buying carbonated beverages from the store

2) Check out the ingredients of your current brands and *gasp* consider trying a new one (we know you're dying for a new pandemic adventure). Try brands with fruit juice flavoring (Iike Spindrift) or organic natural flavors to be extra safe in avoiding sneaky synthetic additives.

3) Consider DIY! You can easily make your own sparkling water at home and have total control over what goes in it, including water quality and flavor choice. SodaStream's Aqua Fizz water carbonating machine uses glass bottles. Or if you're on a budget, consider a more basic model and transfer your newly carbonated water over to glass carafes for storage, or just quickly consume it (not a problem for us!). They also have organic flavoring options and a carbon dioxide cylinder exchange program to reduce waste. You could also experiment with adding your own fruit juice flavor concoctions – the possibilities are endless.

Stay fizzy, my friends.

If you've ever wondered why you get fluoride treatments at the dentist and if fluoride that is added to drinking water is safe, then this article will answer all your questions. Fluoride is a naturally occurring mineral. In the early 1900s, a pair of dentists discovered that fluoride helps prevent cavities and in 1945 cities started fluoridating their drinking water (6). Since then, fluoride has been added to toothpastes and mouthwashes, in addition to drinking water. Read on as we break down the science on the pros and cons of fluoride in drinking water, toothpaste, and more.

Your Summer Guide to Water Safety

How to Promote Fun and Prevent Drowning

Summer has arrived! Cue the backyard BBQs, ice cream sandwiches (or DIY popsicles), and Will Smith jams. During long, hot days, water activities are basically a necessity for creating fun memories and staying cool. Unfortunately, water-related accidents are a leading cause of injury and death for young children (4). So to keep things fun this summer, let's talk about drowning prevention.

Drowning happens in seconds and often quietly (1,3). Permanent disability can result even when drowning isn't fatal (3), since any prolonged oxygen disruption injures our brains. Though it can happen to anyone, drowning is the second most common cause of death for 1-4 year olds (3). Almost 90% of these incidents occur in home pools and hot tubs5,6 (and anything that collects water, even buckets, poses a risk) (3). To keep the children in your life safe and cool, here are 5 water safety tips as recommended by the American Academy of Pediatrics, CDC, National Safety Council, Pool Safely, and Red Cross.

1. Kids' water activities require close supervision at all times

Most drowning incidents occur unsupervised when adults briefly step away or become distracted (4). For this reason, children need vigilant supervision by a designated adult whenever they're around water (4). We can appreciate a relaxing poolside novel or margarita, but the responsible adult/Water Watcher (7) needs to be completely free of alcohol impairment and any distractions (not even Insta). Consider water supervision to be like your greatest Netflix binge – your attention is totally focused, and you don't want to miss a thing. For young children the guiding principle is "touch supervision"– being within arm's reach at all times (3). 5-9 year olds are more likely to drown at public pools (4), so designate a supervising adult even when lifeguards are present (3).

2. Modest safety measures make a massive difference

Physical safety measures are imperative, especially when delightfully curious and unintentionally stealthy toddlers attempt to swim without you! Installing the right type of fence can reduce drowning risk by over 80% – 4-sided pool fences (completely isolating the pool) are far more effective than 3-sided property line fences (3). The safest fences measure at least 4 feet high, prevent climbing, and have self-latching, self-closing gates (3,7). Door alarms and rigid pool covers are also preventive, though their effectiveness is less studied (1). Always check that the pool you use has intact anti-entrapment drain covers (mandated by federal law) to prevent suction-related accidents (7). For portable pools, check out this specific safety guidance.

3. Life jackets are way better than floaties

Sadly those super cute floaty wings aren't designed for safety, according to the CDC, and should not replace life jackets (3) (on the upside, this means less flimsy plastic!). Young children and inexperienced swimmers should wear a U.S. Coast Guard-approved life jacketwhenever near water (1,9). And, regardless of swimming ability, all children need USCG-approved life jackets if playing around lakes or the ocean (2). Life jackets are only effective if they fit well, so check the weight and size limits before using (9). Remember that nothing replaces close supervision! (To help start your life jacket search, we tracked down a more eco-friendly option.)

4. Teach children swimming and water safety

Learning to swim is crucial for water safety. We all benefit from learning how to swim, and swimming lessons can prevent drowning in 1-4 year olds (3). It's never too early (or too late!) to learn – YMCA and community centers often provide affordable lessons for all ages. (We get that communal activities are probably not your jam with the current Covid-19 situation, but, at some point, formal swim lessons could be a fun family activity.) Knowing how to swim does not make us "drown proof" though, so we still need to exercise caution with kids of any swimming ability (1). Teaching children not to climb over pool fences, swim without an adult, or play near pool drains is also crucial for preventing drowning incidents (7).

5. Assess surroundings and swimming ability

Being aware of location-specific water dangers and knowing a swimmer's ability can help discern which activities are safe. Every water activity presents an assortment of fun and risk. Case in point: sprinklers are a simple joy but also an understated toe hazard (been there…). Oceans, rivers, and lakes offer wilder adventure yet can even prove dangerous for expert swimmers – rip currents are an infamous threat in oceans, and lakes and rivers can have undertows (6). Older children and adolescents are more likely to drown in these natural bodies of water (3). Since alcohol can impair your ability to assess surroundings and react appropriately, avoid drinking while swimming or supervising others (7).

Prevention first, but CPR can still save lives

We hope you'll never ever need to use CPR...ever. Prevention with the above measures can massively reduce drowning risk for everyone, but CPR is invaluable during a drowning incident and can improve the likelihood of the drowning victim's survival (3). The American Heart Association provides in-person Family and Friends CPR courses, as well as socially distanced, at-home instruction with Family and Friends CPR DVD or Adult/Child CPR training kits (includes a training manikin and DVD – fun for the whole family!).

With safe water play, we know your summer days will be full of adventure and excitement. Have fun!

Assume that Bottled Water is Safer than Tap...Think Again!

Testing Finds Arsenic in Bottled Water at Whole Foods

Bottled water is marketed as healthy, pristine, and pure. And people believe this, often paying a premium cost for water that they believe will be healthier than what comes out of the tap. Bottled water is one of the most-sold beverages in the United States — which makes it especially disturbing to think that it may not be so safe after all.

What's So Dangerous About Bottled Water?

Recent studies by the Center for Environmental Health and Consumer Reports have found alarming levels of harmful chemicals in bottled water sold across the country. In June 2019, the Center for Environmental Health tested popular bottled water brands Starkey, owned by Whole Foods, and Peñafiel, owned by Keurig Dr Pepper and found concerning levels of arsenic. These levels are high enough that we believe they require a warning label under California state law Proposition 65, but no such label is in use.
