The Lelit In Tank Water Softener needs to be recharged once every 35 liters or less water passing through or minimum once per month. Fits most Lelit espresso machines and other brand espresso machines.

This water softener helps remove limescale causing agents and minerals, such as calcium and magnesium, from the water. This softener does NOT filter the water for chlorine, other mineral particulates, etc just as most water filters do not soften the water.

Please remove this softener when descaling to avoid damage. In most cases, the Lelit water softener needs  should be replaced once a year minimum. Replaces PLA930S.

      Sorry, we are unable to answer as we do not sell Royal espresso machines at this time, and would not know about the size of the hose or the opening of the water tank. We also do not know which will work better as we are not familiar with their water softening cartridges.

      Yes, this water softener will work as we sell them individually. PLA930S is just a kit of 2 of them.

      Better to use the water softener and recharge MINIMUM 2 times per month at this level.

      A It is the smaller of the two Lelit filters. It is the same filter that came with my Victoria and this replacement fits it perfectly. So I think it should.

      We have inspected the resins and they are the same as our other water softeners. We have thousands of customers who have done this recharging. The main point is to replace the resin cartridge every 6 months to avoid build up. In addition, this stems form commercial water softeners used on espresso machines in coffee shops. Furthermore, does one replace all the resins in a whole house water softener? No, there is the addition of salt. You can read more about this. Hence, our belief is different than Lelit's determination.

      However, if you feel their point is stronger than ours, then please go ahead and replace the cartridge every 35 liters as we would love selling you extra. However, we will not like you filling up the landfills with more garbage if not necessary!

      Replacement required every 6 months, just like refrigerators. The reason is to avoid build up of mold, fungus, or bacteria in the cartridge. Even though the water passed through a vessel at greater than 180 degrees F kills most of these, we prefer not to have a reservoir growing these organisms. In addition, the water reservoir should be hand washed with non-abrasive dish wash detergent and sponge every 2 weeks minimum.

      Sorry, this smaller one is not adequate. Please order the 70 liter version.

      A With respect to previous responder, they work just fine in my experience , although for a shorter time. Fitting are correct, and the water line is sufficiently long
      A The 70 liter version is the one supplied with this machine; but I've found that the 35 liter version fits and works well.
