With the Rocket Espresso Water Reservoir Filter, you'll have crisp, clean water with the right amount of minerals to extract a tasty espresso shot. Installation involves moistening the filter and placing it in the water tank. This handy filter will fit Giotto, Cellini and Appartamento machines and many other brands with water tanks as well. Besides providing optimal water quality users will notice a reduction in scale buildup.
How Does it Compare?
The Rocket Espresso Water Reservoir Filter fits Appartamento, Giotto and Cellini models with tanks. The filter should be rinsed under cold water and placed into the reservoir so the membrane sack floats in the tank.
The filters should not be re-energized and once positioned in the reservoir, they should be left there until it is time to replace.
Tips and Tricks
The Rocket Espresso Water Reservoir Filter for espresso machines may last six to 12 months, but varies with usage.
Product Weight (lbs.)
The Rocket Espresso Water Reservoir Filter is made of resin and uses an activated carbon filtration system to filter out limescale, chlorine, and other unwanted impurities.
How does this filter work Does it go inside the water reservoir?

Best Answer:It is a softener in a little pouch; you place it in the water tank and it softens the water in there — does not need to be installed in any special manner, so it will work with most espresso machines.
Best Answer:This filter works very well. You just take it out of the package and put it in the Rocket Water Tank and leave it. I tested my water before using this while in the tank and after using it. The water hardness is definitely lowered by this filter. It works for 1 year according to the package info. I have had it 2 months and it still works fine. I do not think it can be "recharged." The package is sealed and cannot be opened. It is supposed to be a disposable filter that is replaced in 1 year.
Bo T, I simply get the pouch wet which allows it to stay in the bottom of the water reservoir. My unit is not plumed so I just add water when it needs it and leave the filter in the reservoir. I think normal table salt would make your drink too salty? I replace my filter every year. Love, love, love my Rocket!
I have a soft water system on my water supply. My question is, do I need to also use this water reservoir filter in my Rocket machine? Will it damage anything if I use both the soft water and the additional reservoir filter? More is better, right?
A shopper on Sep 9, 2014
Best Answer:Rocket gives a maximum hardness in the manual.You can test your water and determine if you are below that level already. If so then you don't need the filter.
With regard to lower is better, it may not hurt, but there needs to be some mineral level in you water. The boiler sensors use the conductivity of water to determine if it is full. Therefore if you had effectively distilled the water you would see some issues with the machine alerting to waterlevel. I doubt that would happen in this case.
I mix RO water with a bit of tap water to get mine right. I recommend that if your water is okay, skip the filter and just descale on the schedule recommended. Hope this helps. -Bill P
I have the Rocket espresso machine and use the filters. No, you do not need both. In fact, too soft of water will result in an inferior tasting espresso and could result in your machine's auto tank fill to not work properly. It would actually be better to use regular (hard) tap or bottled water plus your filters OR just soft water to the machine without filters. Don't use both
Your soft water system should remove minerals that could harm your espresso machine. Rocket's reservoir filter is designed to also remove minerals from the water. It may be redundant to use Rocket's reservoir filter, given your water supply. But, I don't see how using the reservoir filter could hurt anything.
I dont believe it will do anything but help.I found that mine filtered out quite a bit of impurities in my machine.I use water filtered through a Brita pitcher and the Rocket filter still filtered helped.Yes,in this case more is better in my opinion
A water softener will not always remove the tastes and smells associated with plumbing in general. Using this filter will not hurt anything and your coffee will taste and smell much more like it is supposed to. I never use my machine without one.
I have hard water and no softener. This "filter" (don't know why they call it that) does a very good job in cutting down on scale. I increased the descaling interval to several months and there still does not seem to be much internal scaling ... as evidenced by the Dezcal doesn't turn green like it used to during much more frequent descalings.
If you have soft water and no evidence of fast scale buildup in the tank or internally I don't think you need this.
I don't know if it makes already soft water even softer, but too soft water is not supposed to be a recipe for good coffee.
Will it fit the NS Oscar tight water filling opening?
A shopper on Jul 7, 2013
Best Answer:You could manipulate this Rocket Water Reservoir Filter to fit in a narrow tank like that of the Nuova Simoneli Oscar, however I am not sure how easy it would be to remove after use! For a machine like this, I might suggest using bottled/filtered water instead of this Rocket filter.
The main thing I was waiting to find out: will this filter have any taste whatsoever? Answer: none. I'm now ordering two more. (Posted on 9/19/2016)
works as promisedReview by Marlon K
I am on my third filter in a little more than 18 months of regular use and it functions as advertised. I can well filtered, "purified" water since the packet contains adequate minerals to meet sensor requirements but in the case that someone adds tap water to the mix, it seems to reduce the odd flavors and tastes that often appear in our municipal water supplies.

this worksReview by jp
I have used this for a year. Descaled after 8 months. There was no discolored water during the descale process. In the past I'd seen plenty of blue water. Not this time. I do recommend rinsing this filter on a regular basis...3 months at least. And, my water is moderately hard. (Posted on 1/14/2013)
Looks good at the startReview by Kismet
I have been using this for a few weeks. It looks like it will be easy to use, and seems to work as advertised. There is minimal instruction. No information about recharging. (Posted on 11/30/2012)
