It doesn't fit very well on a Dedica machine and every 2 months, even though I have the filter and use tap water also with a filter, every two months it asks for descaling with a consumption of 2-3 coffees a day.
I don't know if it's worth it or not, time will tell.

I don't know if it really works or not since I also have a separate filter on my tap, but since the manufacturer recommends it, I use it.

It does its job, but it has a short lifespan and it's not worth it.

After 2-3 such purchases, I got a water filter that attaches to the faucet and it saved me.
I wouldn't waste money on this product again.

Does not fit properly in Delonghi Dedica. You need to change the rubber ring so that the filter stays in place. Minimal taste difference in the coffee.

Unfortunately, it doesn't "fit" well on the filter base of the Rivelia, resulting in it coming loose and floating when you fill the container with water, and you have to hold it down with your hand. Poor design from De'Longhi, but unfortunately, there are no alternatives.

I also liked that with the filter the coffee is nicer and has a very nice taste and smell and prevents scale in the machine. You should try it too

I don't know if it does its job well or if it's just for show... the café requested descaling in less than 2 months with moderate use... 3-4 coffees a day

I don't know how well it works. Anyway, for those interested in the Delonghi Dedica EC 685/785/885, it doesn't fit. I adapted it to mine "in a makeshift way" with an additional plastic ring so that it fits properly.

I change the filter in the machine almost every 6 months! I believe that if this didn't exist, the machine would be full of salts! Now it's just fine (desalinating, but not as often)

The coffee indeed has a different taste, the only negative thing is that it lasts for about 2 months depending on the quantity of coffee you make

I find it a bit expensive. Although I use filtered water, I consider it necessary to have it for better taste and for the maintenance of the machine. Only two months of duration? Why?

I don't know if it works for water quality, what I know is that it doesn't fit properly in the coffee maker, causing water to leak out of its position and needing to be repositioned again

I don't feel any difference with the filter unless I'm doing something wrong. I prefer using filtered or bottled water for my coffee.

Excellent filter for the Delonghi Magnifica automatic coffee machine. It protects the machine to a great extent from salts. I have been using it from the first moment.

I had tried the coffee maker without the filter and I can say that it makes a difference in taste, so it probably does something. I also prefer that it somehow protects the machine and extends its lifespan

It does the job it claims. In an area with hard water like Rhodes, where I am located, not using a filter is like asking for problems.
