Filtering device and cartridges for fluids and gases

A fluid filter unit, comprising:

• a shock-resistant casing, having two lateral side walls, at least one peripheral surface delimited by said side walls and inlet and outlet openings made in said side walls,
• a solid filter body having lateral side walls and at least one peripheral surface, said body being sized to fit inside the casing, said filter body being made of a sintered composition of absorbing materials containing activated carbon having a particle size in the range of from 4 to 100 mesh, and a binder in the form of thermoplastic powder having a particle size in the range of from 10 to 250 mesh;
• the ratio of binder to absorbing material being less than 7% by weight, and
• said composition being sintered and solidified into said filter body at a temperature below 250° C., and
• a seal interposed between an inner peripheral surface of said at least one peripheral surface of said casing and an outer peripheral surface of said at least one peripheral surface of said filter body, to substantially prevent direct contact between said filter body and the casing, thereby said seal acting as a shock absorber.
