Hey there coffee lovers! If your Delonghi machine needs some filter love, we've got the perfect solution. This 4-pack of activated carbon water filters is exactly what you need to keep your espresso tasting amazing. These little guys measure 4.7x2x2.5cm (that's about 1.85x0.79x0.98 inches for those who prefer imperial) and they fit perfectly in compatible Delonghi machines. Made with super-strong activated carbon, these filters have awesome adsorption power that really brings out the coffee aroma while protecting your machine from impurities. They're perfect for model 7313285779 and similar Delonghi espresso makers. Changing them out is super simple - just pop open the filter housing in your water tank, swap out the old filter, snap in the new one, and you're good to go! With four filters in the pack, you'll be set for a good while. Just a quick note - these are compatible replacements, not official Delonghi brand filters, but they work just as great. The measurements might vary slightly since they're done by hand, and colors might look a bit different on various screens, but you're getting quality filters that'll keep your coffee game strong. Perfect for daily use and way more affordable than buying filters one at a time!
