Hi Beijingers, We all know that water quality is a serious issue here in Beijing. I'm leaving the city and I'm selling my fantastic BRITA Optimax water filter with an extra large capacity of 8.5 litres for only 150rmb (No bargaining please... It's one third of the price new.). Ideal for families and in the office. Simply turn on the tap for the best BRITA filtered water. The filter is very easy to place on a kitchen shelf or fridge shelf. A few points about this top quality water filter: - MAXTRA technology for soft, great tasting water - Easy to fill thanks to the extra pour through section - Convenient to operate thanks to the practical dispensing tap - "BRITA Memo" electronic cartridge exchange indicator - 8.5 litres (5.3 litres of filtered water): h 22.0 x d 35.0 x w 19.5 cm
