Yes, you must flush the system after changing a refrigerator water filter. Run 2 to 4 gallons of water through the dispenser to purge trapped air and rinse away loose carbon dust—which can cause cloudy water or black specks in your first few glasses.
You should run and discard 2 to 4 gallons of water through your newly installed refrigerator filter. This flushes out trapped air and loose carbon dust, which can cause the water to look cloudy or have black specks.
Yes, water filters can effectively remove Giardia. However, because standard household pitcher filters (like Brita) generally do not catch parasites, you must use a filter certified for "cyst reduction".
Yes, you absolutely must run water through a new filter after replacing it. This essential step, called "flushing," removes trapped air, loose carbon dust, and manufacturing residue so your water and ice come out clean, clear, and tasting fresh.
Drinking water immediately after changing a filter is not dangerous, but it is not recommended. Most filters use activated carbon, which sheds harmless, fine black carbon dust when new.
Is filtered water cleaner than tap water? Filtered water is generally cleaner to drink than tap water. However, that is not to say that tap water is unsafe to drink. Generally, tap water is safe to drink, but not all tap water is created equal.
Flush the system more thoroughly if needed
After replacing the filter, run at least 2–3 gallons of water through the dispenser to clear out any air pockets and residual carbon particles. If the water appears cloudy or contains small black specks, this is normal—it's loose carbon from the filter.
Discard the water and repeat this process a few more times. For newly installed units we recommend discarding at least 1 gallon of water (approximately 8 tall glasses of water). For newly installed water filters we recommend discarding 3-5 tall drinking glasses of water.
Refrigerator water filters are one of the best, most cost-effective ways to ensure your family is drinking clean, fresh-tasting water, but they need to be changed every six months. After six months, three things can start happening: Your filter becomes easily susceptible to becoming saturated with contaminants.
Always flush a new filter to remove air and loose carbon fines: Run and discard 3–5 gallons.
Poop with Giardia is typically pale, light-colored, yellowish, or greenish. It is often described as greasy, fatty, or slimy (due to mucus) and has a very foul odor, often appearing as loose, watery, or, in dogs, "cow-patty-like" diarrhea. These stools may float or stick to the toilet bowl.
Find out how parasites might be getting into your water supply
Yes, you can get giardia from tap water, though it is rare in municipal systems. The parasite is transmitted through the fecal-oral route.
Some filters need 1, 2, or 4 gallons dispensed for a proper flush; refer to the water filter for specific guidelines. Examples: everydrop Water Filter A requires 1 gallon, whereas most other everydrop Water Filters recommend 4 gallons.
Giardia cysts can infect humans and other animals. As in the case of Cryptosporidium, reverse osmosis or activated carbon block filters featuring at least 0.5 micron level filtration are recommended for their removal.
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).
Water filters typically last anywhere from 3 months to 5 years, depending heavily on the filter type, your household water usage, and the quality of your local water supply. The actual system housing, tanks, and valves can last 10 to 15 years or more with proper maintenance.
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.
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 and discard 2 to 4 gallons of water through your newly installed refrigerator filter. This flushes out trapped air and loose carbon dust, which can cause the water to look cloudy or have black specks.
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.
After changing a water filter, you should run 3 to 5 gallons of water through the system (or run the dispenser continuously for about 5 to 10 minutes). This process, called "flushing," removes trapped air pockets and loose carbon fines that make the water appear cloudy or gray.
If you recently replaced the water filter and the water appears cloudy, it could be because of air or excess carbon in the water line. This is normal when using the water dispenser for the first time or after replacing the filter. Flushing the water system can help resolve these concerns.
Yes, you should turn off your aquarium filter during a water change if the water level drops below the intake tube. Running a filter dry or sucking in air can damage the motor or break the siphon inside the hoses.
