Question: Will this work if I buy coffee that is ground extra fine - (Finer than sugar, but not quite powdered)?
Document: I've used these forever, they work great. This one I hope will hold up for quite some time. Worth it! It keeps any extra grounds from getting into the pot of coffee.
This "Gold Tone" filter is OK for some people I suppose. Since one would have to wash it in the disahwasher or by hand, everyday coffee drinkers might want 2 so that when 1 is dirty the 2nd can be used. It was unusuable for us though. It will not take fine ground coffee without leaving sediment in the pot and therefore in your cup. The instructions say coarse ground coffee should be used but you don't know that before you buy and until you read them! Paper filters are inexpensive and work well.
I grind my coffee beans each morning and I prefer a finer grind as I like strong coffee. I have always used the Melitta natural brown unbleached paper basket filters and I thought I'd try the Mr. Coffee filter so I didn't have to buy any more paper filters. The coffee grinds somehow get through and it makes my coffee murky. I am back to using the paper filters as they work much better.
I really appreciate this product. I bought it to go with my new Mr. Coffee drip coffee maker (Mr. Coffee BVMC-SJX33GT 12-Cup Programmable Coffeemaker, Chrome), and it works flawlessly. I use it daily at work, so I appreciate not having to buy and change filters.The only possible issue with this product is that if you use very finely ground coffee you may end up with a little bit of a flow through. That is a slight amount of grounds seeping through. This is only noticeable on the last cup though, and doesn't happen at all with a regular grind.
I use this in my Black and Decker, and it works great. The other reviewers are right in that it does allow some of the finer grinds into the coffee pot. I just make an extra cup so those grounds are always left in the pot and not my cup.
Allows the full flavor (and oils) of the coffee to reach my tastebuds without any supposedly cancer-causing fibers from the paper filters.Whenever the water goes around the coffee grounds, I simply re-pour the coffer into the strainer to ensure a strong enough outcome. It's quite worth the extra step to steer clear of paper and enjoy French-press caliber flavor. My coffee tastes as wonderful as anyone's, if not better.
The filter lets fine coffee particles through so I have to make extra coffee and throw out half a cup or drink the grit.
Anything to slow down the water flow. For those who have large overzealous holes in their filter holders (like myself) stick with paper  As for the small amount of &#8220;commercially ground&#8221; coffee bean oils getting through, it doesn't bother me, but for those who grind their own dark roast beans, concerns may be over watching their LDL cholesterol levels, definitely paper.In conclusion, unless they can manufacture these with a finer pored screen, these so-called filter (more like &#8220;coffee screens&#8221;) are handy to have in case one runs out of paper filters.
Perhaps this is something to attribute to all permanent filters, but when coffee is ground and used in this filter, about a half a cup of coffee from any measured amount of cups made is rendered unusable because of the finely ground pieces that have made their way through to produce a sludge. It's a shame, since my fiance and I are trying to become more environmentally friendly. However, I do enjoy the fact that we don't have to buy paper filters anymore.
I purchased this with a new Mr. Coffee coffee maker on amazon and was pleasantly suprised at the quality and function. This badboy does not collapse like paperfilters at times. Also, I think the flavor of the coffee is richer. Cleaning is easy, tap ground into the garbage or compost and rinse out holding the filter upside down - done in seconds. With amazon's prime free delivery, I will buy it again when needed - but I don't see it wearing out anytime soon.
Answer: The basic answer is 'no'.  It didn't work when I ground my coffee at 'fine' on the Bunn Commercial coffee grinder.  It overflowed the basket almost every time.  The finer coffee will just make it worse.  The problem is the bottom which is solid plastic with no holes and the coffee just plugs the screening.  Sorry, that is my finding.
