<p>PURPOSE:To provide a deodorizing filter with small pressure loss and excellent deodorizing properties. CONSTITUTION:A deodorizing filter wherein a particulate deodorizer is sandwiched between fiber sheets contg. a thermoplastic fiber at least in one of them by partial ultrasonic fusing is provided. In addition, when the particulate deodorizer is fixed by adhesion with an emulsion-type adhesive at least to one of the fiber sheets, deodorization is uniformly performed and when the deodorizing filter is subjected to pleat treatment, the deodorizing properties and dust collecting efficiency become more excellent.</p> |
