Do you recommend whole house filtration?

For most people on public water supplies and using a single system on the incoming mains supply - not really unless a household member has an allergy problem with chlorine or organic chemicals. Whole house filtration only adds around 1/10th of a penny per litre but by far the greater proportion of domestic water is flushed to drain. Also, the filter will remove the chlorine anti-bacterial disinfection deliberately dosed by the water supply company. A far superior recommended method is to plumb-in the in-line 'Moby' system to each cold tap and the cold feed to the hot water system. In this way you can select only those outlets that need filtration at the point of use and, for example, not bother to filter the water to the toilets. A little more expensive at first but far cheaper to run.
