Very affordable alternative to original water filter coffee machines

After the filters are outrageously expensive for my coffee machine, I now befülle this with the Refill. At least visually, it looks exactly like the contents of the filter. In addition I have the top side a hole (about 8mm) drilled (and clean deburring). The used granulate can be easily rinsed out, the empty case I descale additionally still with citric acid. After filling using a small funnel to the bottom of the hole (not higher because the granules swell and somehow still has almost busted me the first filter) I shut the whole sealed with a tape that is wrapped tightly. It is important that the hole is completely sealed. So far I have (bought for testing) from a bottle filled 3 filter and the granules be sufficient for at least 6 more fillings. The saving everyone likes himself calculate (at a price of 11,99Euronen per original filter). The filling is not a problem even for less experienced hobbyists. Buyer of Doppelpackung wirds again cheaper. This is not advertising for any device, or any PRINCIPLE, any substance or anything else! HERE is simply my experience and OPINION played.
