A Domfilter is a domestic espresso machine filter. Where there is access to the water inlet pipe a domfilter can be fitted.

It connects from the top to the internal water pipe. Where there are two pipes, this will typically be the longest, sat in the water tank.

The domestic espresso machine filter uses the same resin as the Brita water filters. Available as single units, the cheapest way to buy this useful item is in bulk.

Happy Donkey also offer water filters as a bulk pack of 10. Choose the option from the list. We have customers who have used these for over 10 years. They continue to use this filtration.

How water filters can help make better coffee.

Domfilters protect the machine against scale build up. Protection from limescale and impurities. Better tasting home coffee with an improved aroma. A little filter can go a long way. Get the edge for making great home coffee. Keep the espresso machine in shape at the same time !

Please note that this filter will not eliminate scale altogether. Nothing does. It is merely a tool to help guard against it. Use in conjunction with a Brita Filter jug and domestic coffee machine de-scaler. These will help you keep your machine in good shape.

What a winner. Use these filters, a domestic espresso grinder and some fresh strong Italian coffee beans. Grind, filtrate, brew and serve. Sit back and enjoy the envy ! Because you can !

Filtering bacteria and particles with the Gaggia Classic water filter.

Scientists refer to nasties in water collectively as particles. From copper to iron and beyond. From bleach like additives such as chlorine. Undesirable elements such as silt.

Wherever the water comes from it will contain particles of some sort. Filtering these out will give advantages.

Water is a complex but important subject. Moreover we are still learning more about it. Why not have a read of the article on the water hardness test kit.

Gaggia classic water filter – application

The same resin beads found in top rated commercial filtration systems. In a mini unit ! Easy to fit and easy to use. Quoted as a maximum of 150 litres.

Happy Donkey suggests use is limited to 50 Litres. Once the basics of filtration are understood application is easy. The information available is substantial but simple.

Can’t be bothered to read the article on our blog listed above? Just buy these Gaggia classic water filter unit.  Change them every 1-3 months! There is no magic water filtration silver bullet.

The evidence is in the taste. There is only ever help. that is what Domfilters give you. Some people change them at the start then half way through  a trade box of Italian Coffee Beans. A great way to measure useage.

Filters water on other coffee machines too !

Take any domestic coffee machine where access to the water inlet pipe is available. The connector is multi tiered. Therefore making it flexible for a multitude of coffee machines. For instance the Expobar office Leva or the Brewtus, remember those? The Gaggia Baby (most models, check first). The Paros, Cubika, Coffee Delux, Rancilio Silvia and Audrey. As well as the Iberital Hand fill machines. AKA the Iberital Handy.

The list goes on forever.  Because rest assured if the tank inlet pipe is available. The domfilter will work. Please be aware at times the filter cases are white.

More often they are clear. It all depends what is available. The effect on the water for the coffee is the same ! For commercial applications why not have a look at the Brita solutions in the water filters for coffee machines section
