Your Brita is growing algae because the filter strips the tap water of chlorine, which removes the disinfectant protecting it. Combined with airborne algae spores, ambient warmth, and sunlight, this creates the perfect environment for algae to bloom.
How long can I store water in my Brita® pitcher? Store your Brita® pitcher in a cool, dim place. Don't keep your Brita in bright sunlight, as it can cause algae to grow. Keep your Brita in the refrigerator if you plan to be away for longer than a couple of days.
Green Algae in Water Filters: Safety and Precautions
Consuming water with algae may cause mild digestive discomfort, especially in infants. To ensure safety, thoroughly clean and disinfect the pitcher regularly, replace filters as recommended, and avoid using water that appears discolored or has visible growth.
Long-term health effects: Chronic exposure to algal toxins have even been linked to long-term health problems in the liver and even neurological problems. While severe cases are rare, it depicts the importance of preventing algae growth in water storage tanks to safeguard public health.
The presence of algae in drinking water not only causes unpleasant taste and odour but may also lead to the release of harmful toxins. These substances can pose significant health risks, particularly to vulnerable populations such as children and the elderly.
No. Treatments such as boiling, disinfecting water with chlorine, or water filtration units do not remove cyanotoxins. Do not drink water from a water body with a suspected or posted harmful algal bloom.
Yes, Brita filters and pitchers can get moldy. Because the filter and reservoir stay constantly moist and the water is stripped of its chlorine (which typically slows organic growth), they are highly susceptible to black, pink, or green mold if neglected or exposed to heat and sunlight.
Exposure to harmful algal blooms (HABs) can cause sickness through skin contact, swallowing contaminated water, or inhaling airborne droplets. Symptoms typically appear within hours to 2 days.
what's the difference? Well for one, mold is much more dangerous and difficult to remove – mostly because it is often caused by deeper issues in your home. Algae is simply a plant enjoying a life full of sunshine and moisture on your roof.
Drinking algae-affected water or consuming food (such as fish or shellfish) containing toxins can lead to gastroenteritis, which can induce vomiting, diarrhoea, fevers and headaches. These toxins may also affect the liver or nervous system. If you are concerned for your health, see your GP immediately.
Brita filters are ineffective against substances such as nitrates, bacteria, and certain chemicals. If your water supply is contaminated with these, you may need to explore additional treatment options.
HEALTH IMPACTS
If cyanotoxins over the U.S. Environmental Protection Agency's national 10-day Health Advisory level (see Table 1) occur in tap water, people are at risk of various adverse health effects including upset stomach, vomiting and diarrhea as well as liver and kidney damage.
Brita (owned by The Clorox Company) faced a class-action lawsuit for alleged false advertising. Consumers claimed the company misled the public into believing its water filters completely eliminated hazardous contaminants—such as "forever chemicals" (PFAS), arsenic, and uranium.
Wash your Brita pitcher and reservoir thoroughly with warm water and mild dish soap every time you replace your filter. For the standard pitcher, this is generally about once a month (or every 40 gallons). However, if you leave your pitcher on the counter instead of the fridge, you should wash it every 1 to 2 weeks.
No, algae and mold are completely different organisms. Algae are plant-like, photosynthetic organisms that thrive in sunlight and moisture, while mold is a type of fungus that feeds on organic materials and grows in dark, damp environments.
To remove the algae growth, soak the affected area in undiluted Milton solution (available from your chemist). Leave the solution overnight then rinse thoroughly.
To prevent algae growth in your Brita pitcher, always store it in the refrigerator, keep it out of direct sunlight, wash it thoroughly with soap and water every week, and replace the filter every 2 months (or 40 gallons).
Symptoms generally begin within 24 hours and last 72 hours.
Blue-green algae is a toxin-producing cyanobacteria that can be found in lakes, ponds and rivers. Exposure to toxins produced by these bacteria can be life-threatening to dogs, humans and other animals. There is no antidote for blue-green algae poisoning, and it can rapidly become fatal.
Early signs of mold exposure frequently mimic seasonal allergies. They include sneezing, a runny or stuffy nose, coughing, postnasal drip, and red, itchy, or watery eyes. Skin irritation or rashes may also occur, and mold can trigger or worsen asthma symptoms like wheezing and chest tightness.
Dawn dish soap itself does not chemically kill algae. However, it acts as an excellent surfactant. It breaks the surface tension of water and lifts algae off surfaces, making it highly effective when used alongside mechanical scrubbing or as an additive in DIY exterior cleaning solutions.
In A Nutshell: Misconceptions About Mold
Your home can be 100% mold-free: No, there are always mold spores in the air. Anyone can effectively remove mold: No, you need professional services for that.
There are five commonly recognized HAB related illnesses: Ciguatera Fish Poisoning, Paralytic Shellfish Poisoning, Neurotoxic Shellfish Poisoning, Amnesic Shellfish Poisoning and Diarrheic Shellfish Poisoning. At this time, routine, clinical diagnostic tests are not available for any of them.
The water may appear green and may have strong, musty or organically polluted odours. Blue-green algae may be visible as clumps or as scums. The 'blooms' should be considered to be toxic to humans and animals, and the water should not be used for drinking (without prior treatment), stock watering, or for recreation.
Direct contact or breathing airborne droplets containing high levels of algal toxins during swimming or showering can cause irritation of the skin, eyes, nose, and throat. Rashes can develop when skin is exposed to the algae.
