Skipping your fridge's filter replacement means it will become clogged with trapped contaminants. This causes slow water dispensing, foul-tasting or smelly water and ice, and potential mold or bacterial growth inside your appliance.
Refrigerator water filters should usually be replaced every six months for easy and reliable access to fresh drinking water for the entire family. Learn more about fridge water filters and how they work.
The buildup of organic matter can begin to impact your overall water quality, leading to unpleasant odors and tastes. Continuously drinking water that's been contaminated by harmful bacteria can lead to severe health risks, including diarrhea, nausea, fatigue, and an overall weakened immune system.
Yes, certain water filters can remove Cryptosporidium. Because this parasite is highly resistant to chlorine and standard municipal treatments, physical filtration is one of the most effective ways to make your drinking water safe.
Yes, refrigerator water filters absolutely need to be replaced. Most manufacturers recommend replacing them every 6 months. Over time, the internal filter media becomes saturated with contaminants, meaning it will eventually stop cleaning your water and could even harbor bacteria.
Most refrigerator water filters last for 6 months or 200 to 300 gallons of water usage—whichever comes first. However, if your household uses less water, the filter should still be changed at least once a year, as the activated carbon inside the filter degrades and loses its effectiveness over time.
Using an expired refrigerator water filter can expose you to these harmful chemicals and contaminants: Lead—Harmful lead exposure can cause neurological, behavioral and health problems in children and adults. Heavy metals—Heavy metals include arsenic, antimony, cadmium, chromium, copper, lead, selenium and many more.
The first signs of a Cryptosporidium (Crypto) infection typically appear 2 to 10 days after exposure, averaging about 7 days. The hallmark of this gastrointestinal parasite is sudden, watery diarrhea.
Cryptosporidium ("Crypto") is extremely resistant to standard disinfectants. Standard chlorine bleach and alcohol-based hand sanitizers are ineffective.
Yes, certain water filters can effectively remove or reduce PFAS ("forever chemicals") from drinking water. The most effective technologies are reverse osmosis (RO), granular activated carbon (GAC), and ion exchange resins. For best results, look for products certified by NSF/ANSI 53 or 58 for PFAS reduction.
Feeling sick after drinking filtered water is likely caused by a neglected, poorly maintained, or improperly installed filter that allows bacteria or mold to grow and pass into the water. Other causes include chemical residues from the filter, high mineral content (hard water), or drinking on an empty stomach.
Whatever your reasons, it's time to think again and take a wiser step. Yes, many refrigerators are designed to run even if their water filter is not installed. However, running the system after removing the filter is not advised. Drinking unfiltered water can harm your health and make you sick.
You can determine if your tap water is making you ill by identifying specific physical symptoms, evaluating localized signs in your plumbing, and testing your water supply.
Study: Bacteria can grow in faucet water filters. Water filters that you attach to your faucet are known to be good for filtering out heavy metals like lead and disinfectants like chlorine. But they're not designed to filter out bacteria that can grow in the filter itself.
No, you generally do not need to turn off the water supply to change your fridge filter. Most modern refrigerators (like Samsung, LG, Whirlpool, and KitchenAid) feature an automatic internal shutoff valve. When you twist or pull the old filter out, the housing automatically blocks the water flow to prevent any leaking.
Filtered water lasts for 3 to 5 days in the fridge, and up to a week if it is kept in a clean, airtight container. Because filters remove chlorine and disinfectants, the water is more susceptible to bacteria and should be consumed quickly for the best taste and safety.
Cryptosporidium infection (crypto) typically causes profuse, watery diarrhea, often described as loose and bulky. It frequently contains mucus, but in most cases, it does not contain blood or pus. The feces will look like typical severe diarrhea—unformed, liquid, and passed frequently (sometimes 10+ times a day).
Cryptosporidium and chlorine
Cryptosporidium parasites are one of the more common causes of infectious diarrhea in human because they are not easily killed by chlorine and can survive up to 10 days in properly treated water.
The only way to definitively know if you have a parasitic infection is through specific medical testing, such as stool tests, blood work, or imaging, ordered by your doctor.
Yes, Cryptosporidium (often called "Crypto") is highly contagious. It is a microscopic parasite that causes watery diarrhea, stomach cramps, and dehydration. It spreads easily for a few distinct reasons:
The single deadliest parasite to humans is Plasmodium falciparum. This microscopic, single-celled protozoan is the most lethal of the parasites that cause malaria. Transmitted to humans through the bite of infected Anopheles mosquitoes, it is responsible for the vast majority of the world's estimated 600,000 annual malaria deaths.
There is no way of telling by taste, sight or smell if soil, food, water or a surface has Cryptosporidium or Giardia parasites.
Not necessarily. While most manufacturers recommend replacing your filter every 6 months (or 300 to 500 gallons), the true timeline depends on your household's usage, water quality, and the age of the filter.
Run about 2 to 4 gallons (roughly 32 to 64 cups) of water through a new fridge filter to remove trapped air and loose carbon dust.
Fridge filters are designed to handle basic impurities like chlorine and sediment, but they typically don't remove more harmful contaminants such as lead, PFAS, pharmaceuticals, or pesticides.
