I use a twin filter unit connected by white micro pipe.
Bought off eBay. First one was a generic single seal unit made in china, it split where the brass knuckle joins the two filter containers together.
Second purchase was for an identical looking unit, but with twin seals, and made in the good ol' US of A, and only a few more $$.
Great bit of kit, first filter is sediment, in HK I need to change it every 3-4 months, but cartridges online are cheap as chips, the second cartridge is charcoal, and this gets changed the second the taste goes 1 dot below the "Fark me, I didn't know water in HK could taste so good" glideslope. This is about every 4-6 months.
