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.
Before first use, run cold water for 5 minutes in a filtered position. During filter flush, it is normal to see cloudy water and hear the sound of water pushing air out of the filter cartridge. Flushing removes any loose materials, which is normal.
Yes, specific water filters can remove Cryptosporidium. Because this parasite is typically between 4𝜇m and 6𝜇m in size, physical filtration is highly effective if the filter pore size is small enough.
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.
Run two to four gallons of water through the new filter. This helps prevent your water dispenser from sputtering and clears impurities left over from manufacturing. Check for leaks around the filter.
After replacing your refrigerator water filter, you must flush the system to remove air and loose carbon, reset the indicator light, and discard the first batch of ice.
Run 128 to 512 ounces (1 to 4 gallons) of water through your new fridge filter. This flushes out manufacturing residue, trapped air, and loose activated carbon particles.
When water tastes bad after replacing the filter, it is usually temporary. The new filter may need conditioning, or the system may need flushing to remove air bubbles and trapped dust. If the taste doesn't improve after a few gallons, check for: Wrong filter size or model.
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 1 to 4 gallons (about 16 to 64 standard cups) through a new refrigerator water filter before drinking. This clears trapped air and loose carbon particles.
Diarrhea, vomiting, stomach cramps, and weight loss are the most common symptoms. Dehydration is the main complication. People who have a healthy immune system usually recover without treatment. People with a weak immune system may get a more serious infection and need supportive medical care.
There is no single state with universally the "worst" tap water, as quality varies by utility. However, based on high contaminant counts, EPA violations, and population exposure, Texas and New Jersey consistently rank at the bottom.

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.
New tank syndrome typically lasts 2 to 6 weeks (though it can stretch up to 12 weeks). It resolves only when a stable colony of beneficial bacteria establishes itself to break down toxic ammonia and nitrites.
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.
What are the disadvantages of drinking filtered water? Filtered water may lack essential minerals, and poorly maintained filters can lead to bacterial contamination or exposure to heavy metals.
Yes, fridge water comes from the same source as your tap water (municipal supply or well), but it is generally cleaner and better-tasting because it passes through an on-board activated carbon filter. Fridge filters reduce chlorine, sediment, and heavy metals, offering better taste and safety than unfiltered tap water, but they are not designed to remove all contaminants.
Filtered Taps: Some bathroom taps come with built-in filters designed to improve water quality. These filters can remove impurities like chlorine, sediment, and some contaminants, potentially making the water safer to drink and improving its taste.
After replacing a water filter, you must flush the system to remove trapped air and loose carbon particles. For a refrigerator, place a large container against the dispenser and alternate holding for 5 seconds and releasing for 5 seconds until water flows steadily. Finally, dispense 2 to 4 gallons to completely clear the line, and reset the filter indicator light.
Not changing your water filter can lead to illness because trapped contaminants, bacteria, and mold can form a biofilm. These can leach into your drinking water or multiply. If you are experiencing symptoms, the priority is to address your health, remove the old filter, and sanitize your system.
Tap water contains naturally occurring minerals like calcium, magnesium and sodium which contribute to its taste. When you filter your water some of these minerals are removed, especially with more advanced filtration systems like reverse osmosis. As a result the water tastes "softer" or "flatter".
It is not dangerous to drink the water, but you should not drink the first 1 to 4 gallons after changing your filter.
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).
