Well I do think they are supposed to be filters, I have seen them before with filter material in them. But the ones supplied definitely do not have any filter material in them and do no seem to come apart to install any so I can see no advantage to using them over just removing the bung! Mine are sat in my draw for just that reason. Anyway Ian we all lurk in the background and just pounce when necessary.Originally Posted by Ian M

Shh Hush, while we've been discussing it PC World and Maplins have just increased the price by £80.00 since Sunday.
The 5910 goes up and down in price like a yo-yo. I think it is one of these products that is often used by retailers to say 'was £189 now £99' for which obviously it keeps going back up for at least 28 days lol.

They're called filters.

A Filter is a porous device for removing impurities or solid particles from a liquid or gas passed through it. As these plastic pieces as supplied with the Brother cartridges do not in any way shape or form filter anything they are not filters - if and when you fill them with filter material then they can be called filters. They are also not really a funnel so maybe they should just be called plastic vents lol

We didn't say they WERE filters, we said they WERE CALLED filters. But thank you very much for the lesson anyway, always appreciate a smart arse

Well I searched hi and lo to find an answer on google and there did not seem to be an answer as to what they are called. I think that they were ultimately designed to be a filter as I have seen them with filter paper in the flyingsaucer shaped bit. As supplied however with my cartridges they have no filter material and they seem to be sealed so cannot be opened to put filter material in. In fact as they are they seem to have no advantage over just removing the bung as they do not stop anything entering the holes. As they would say 'as bout as useful as a chocolate teapot'We didn't say they WERE filters, we said they WERE CALLED filters. But thank you very much for the lesson anyway, always appreciate a smart arse

OK try & get your head around this.Well I searched hi and lo to find an answer on google and there did not seem to be an answer as to what they are called.

A CISS system is based on the Mariotte's bottle principle. This is a stoppered reservoir supplied with an air inlet and a siphon. The pressure at the bottom of the air inlet is always the same as the pressure outside the reservoir, i.e. the atmospheric pressure. This then helps to push the ink through the tubes to the cartridges that feed the print head or tubes from the cartridges to the print head.
The air filters are there to control the atmospheric air pressure & also have a dual purpose to keep out things such as dirt or dust that may contaminate the ink.
Now on my broadband I have a filter on there which doesn't have any paper inside as it is there to filter the signal.
So, going back to Mariotte's bottle principle this means a filter not only cleans it can also be used to control.
As for bungs well, I know where I would like to shove one
Having downloaded and read a CISS manual it seems they are not bungs they are 'Air Balance Plugs' lol - Lets just assume that items that come with CISS are called 'Air Balance Plugs' and 'Filters' due to some damn awful chinglish translation (or a wish to make simple objects appear fancier than they really are). Whatever we decide to call them is I suppose irrelevant as long as it defines the object in question enough to allow someone new to refillable or CISS systems to work out what we are talking about.

An air balance plug is the rubber stopper that you replace with the air filter. You can call them whatever you want but, the rest of us will stick to what they are really called.
All you will do is confuse someone who is new which is probably what you are doing already.Whatever we decide to call them is I suppose irrelevant as long as it defines the object in question enough to allow someone new to refillable or CISS systems to work out what we are talking about.
