<p>PURPOSE: To prepare a deodorizer which can keep excellent deodorizing performance for a long time, a small-sized deodorizing filter with low pressure loss using the same and to provide a deodorizing apparatus. CONSTITUTION: This deodorizer consists of a porous adsorbing material and a spreading agent contg. amino group. The spreading agent is incorporated by 25-100wt.% into the porous adsorbing material. For example, the porous adsorbing material is active carbon and the spreading agent is 3- aminopropyltrihydrosilane. In the deodorizing filter, this deodorizer is carried on a porous carrier with three dimentional net work structure. The porous carrier is a polyurethane foam with 8-20 pieces/inch cells and it is pref. that 0.03-0.20g/cc deodorizing agent is carried on the polyurethane foam.</p> |
