HP Envy 4524 Deskjet 3636 Officejet 4658 use HP302 Ink Cartridges

Three of the latest Hewlett Packard printers require the HP 302 ink cartridges.  Unfortunately these cartridges do not hold very much ink.  Much of the internal space is a blanked off empty space of air.  HP do not state how much ink is contained in the standard HP302 cartridges; instead they quote 190 pages at 5% coverage.  There is an internal sponge which holds a small amount of ink that is probably only a few ml. 

With the price of original ink cartridges going through the roof at the moment, it makes sense to refill your cartridges.  Of course doing this also saves on landfill!  Eco-Fill offer a dedicated refill kit for the HP302 printer cartridges which are used in the HP Envy 4524, Deskjet 3636, and Officejet 4658 printers, as well as the existing... HP Deskjet 1110, 2130, 2132, 2134, 3630, 3632, 3634, 3636, 3638, HP Envy 4520, 4522, 4523, 4524, 4527, HP Officejet 3830, 4650 printers.
