Replace your refrigerator water filter every 6 months (or after dispensing 300–500 gallons of water), whichever comes first. If your household is large, you use the dispenser heavily, or your tap water is highly mineralized, you may need to replace it more frequently.
While the 6-month timeline is a standard recommendation by manufacturers, the exact answer depends on your usage and your home's water quality. For light usage with city water, you can often stretch it to 9–12 months, but going much longer risks contaminated water and appliance damage.
Most refrigerator water filters last 6 months or filter about 200 to 500 gallons of water, whichever comes first. After this point, the carbon inside the filter loses its ability to trap contaminants effectively, and the moist environment can become a breeding ground for bacteria.
You know your refrigerator water filter is bad if it causes a drop in water pressure, dispenses cloudy or strange-tasting water, or produces small/oddly shaped ice cubes. Most manufacturers also recommend replacing the filter every six months, or when the fridge's indicator light turns red.
Skipping your refrigerator's water filter replacement means your water and ice will no longer be purified. Over time, a neglected filter becomes clogged with captured debris and bacteria, which can cause foul tastes and odors, slow water dispensing, and potentially release contaminants into your drinking supply.
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.
You should run 2 to 4 gallons of water through a new fridge filter before using it.
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.
Filter seems clogged
Your refrigerator water filter may not last the industry standard of 6 months. This depends on your water quality and usage. If your water pressure starts to slow, your filter could be clogged. First, check the system's valve to ensure it's not affecting the water pressure.
As time passes, minerals and particles accumulate and eventually plug up the water filter. Without proper cleaning, a dirty water filter can clog up with so much debris that water can't get through it. When this happens, your machine can freeze up completely, meaning your ice machine won't be able to produce ice.
Yes, refrigerator water filters do work, but primarily as "cosmetic" filters. They are highly effective at improving the taste and odor of your water by removing chlorine and trapping large sediment, but they are not designed to purify water of heavy metals, pharmaceuticals, or deep contaminants.
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.
Yes, a bad or clogged water filter can severely affect your ice maker. It can cause no ice to be made, slow down ice production, or result in small, hollow, and foul-tasting cubes.
Most refrigerator water filters last 6 months or filter about 200 to 500 gallons of water, whichever comes first. After this point, the carbon inside the filter loses its ability to trap contaminants effectively, and the moist environment can become a breeding ground for bacteria.
Yes, you can use your refrigerator without the water filter, but how you do it depends on your specific model. Many modern refrigerators require you to insert a "bypass plug" in place of the filter to allow water to flow to the dispenser and ice maker.
You should run 2 to 4 gallons of water through a new refrigerator filter before drinking it. This process clears trapped air pockets and flushes out any loose, harmless carbon dust leftover from manufacturing.
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.
Yes, an old refrigerator water filter can absolutely make you sick. As filters age and trap impurities, they can become a breeding ground for bacteria like E. coli or mold. Additionally, the filter’s carbon core stops working, allowing heavy metals and chemicals like lead back into your drinking water.
It's important to flush the water system as often as you change the water filter.
There is no single “#1” healthiest water, as the ideal choice depends on your specific health and hydration needs. However, experts generally agree that naturally mineralized spring water and carbon-filtered tap water (especially when remineralized) are the best daily options.
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.
A pound of KDF like what this cartridge has should filter close to 50,000 gallons of water, or about 10x what regular carbon media would filter. By the math, if a regular carbon filter has a usable lifespan of 6 months, then this filter should last 5 years.
Modern household refrigerators typically average ~0.8–2.0 kWh/day. At an electricity price of $0.15/kWh, that's about $0.12–$0.30 per day, $3.60–$9.00 per month, and $43–$110 per year (your exact cost depends on model, settings, climate, and usage).
