De'LonghiWater Filter DLSC321 - Softener and Purifier for Coffee Makers, Active Carbon Filter for Machines, Maintenance Accessory, 8 Months Duration, 4 Filters

Amazing value for money when bought in bulk like this. They fit as should as are made by the manufacturer. They last as long as the machine decides based on your water hardness in your area. Very easy to install on our DeLonghi Rivelia. Quality is as expected from the brand and functionality also as expected.

Good as always does the job

I bought these direct from Delonghi when I bought my Rivelia bean to cup machine. The sample filter which came with the machine is slightly different and I was able to install it, no problems. These ones however are slightly different (but what Delonghi sells as replacements) and I -and several others- seem to have problems with them floating in the water tank despite following installation instructions.For me I can't get the filter to fill with water (step 1) and there's also no room in the tank to get my hand in for the step where you squeeze air bubbles out. My solution: fill a container with clean water -make sure there's enough space to move the filter around, and that the water is deep enough so the filter stays completely immersed even when you flip it on its side. Hold the filter under the water. Be patient. Move it around and squeeze it in different places to release any air bubbles and fill the cartridge. When no more bubbles are released as you repeat these steps, transfer to coffee machines water tank -I covered the 4 intake holes with my fingers as I took it out the container and transferred it. Give the filter a final few squeezes when it's submerged in your coffee machines tank. Then place in its holder and complete the installation on the machine (mine runs water through the filter and rinses it). Should then be good to go and can easily refill the tank to max without any floating filters!Worth taking time to follow these steps for stress free operation.Great price on here, especially with subscribe and save. I live in a hard water area so also want to look after my machine. As it is I put filtered water in the machine then refilter it with this.I notice a difference in the taste of the coffee too.
