Abstract

It is taken for granted that paper filters (inert cellulose filters) do not affect water. However, our experiments show that after such filters repeatedly touched water, the liquid is modified. For example, the liquid’s electric conductivity, density, structure and composition are modified. The modifications neither are ascribable to impurities present in the filter nor to organic- or biological pollutants. Our data show that the filters instigate association of water molecules and produce organic molecules. Seemingly, the water-filter interface catalyses reactions involving atmospheric molecules. Our findings may have implications for procedures wherein water repeatedly touches cellulose filters.
