I purchased 4 Duo Filter F472 for my FMF5. These filters should last through all of 2009 if replaced every 3 months as stated on the box. I noticed my coffee tasting a little bitter over the past few weeks. We throw the carafe in the dishwasher along with all of the parts. I then decided to replace the filter a month early and I noted two shocking things. 1: the filter and the grey filter holder had mold all over it. We could not even pull the filter out without it sticking. 2: The base were the filter holder sits had a puddle of water in the unit. This unit has not been used in over two weeks. I have contacted Krups and they have stated that I need to wait for a supervisor to call me back (24-48hrs) and I should be using a calcium "calcify"cleaner in the machine "often". No exact amount of times but "often" was given.
Be aware that you might have to wipe the water out of the base under the grey filter holder.
Krups suggests :
Descaling
Descaling is necessary to keep your coffee machine running efficiently. The frequency of
descaling depends on the hardness of your water and how often you use the coffee machine.
If you notice the brew cycle has slowed it is generally time to descale the machine.
See the chart below:
Type of Water Without Duo Filter With Duo Filter
Water Filtration Water filtration
Hard 40 uses 80 uses
Soft 80 uses 160 uses
* Before descaling, remove the filter holder (k).
* You may use either the Krups descaling solution diluted in 8 ounces of water or 8 ounces of
white vinegar.
* Pour the solution or vinegar into water reservoir (b) and start the coffee machine (without
coffee).
* Allow half the liquid to run into the carafe, then switch off and let stand for 1 hour.
* Restart the coffee machine to complete the cycle.
* Rinse the coffee machine by running it through 2 full cylces with water only.
* On the timer models if the display continues to read "CALC" repeat the process again.

Krups 472-00 DuoFilters, Two Pack: Although I have repeatedly used Krups water filters with my Krups coffee maker, this was the first time I ordered the product from this company through Amazon. The price was most economical as was the S&H charge. My order was promptly handled and in my hands in record time. I am most happy with this purchase.

Excellent filtration
I hadn't bothered to replace the filter from my Krups machine (which we received for our wedding, 2.5 years ago). I finally purchased more filters. Read more

Krupp bean grinder and coffee maker
Krupp bean and grind coffee maker -- very disappointed -- it broke down and would not brew regular coffee in less than one year. Would not recommend it.

Great water filter!
These little Krups water filters are invaluable when brewing coffee. The charcoal filter helps to filter out the bad tasting tap water and make the finished product taste great.

Keeps the coffee crisp and fresh
Amazing how a water filter can make coffee taste so much better. Besides the bean, the water is most important for a good cup of Joe. Read more
