| 摘要 |
The present invention relates to a microbicidal filter (100) for treating air, including, in the flow direction (A) of the airstream capable of passing therethrough, a filtration layer, a HEPA filter. According to the invention, the filtration layer (110) contains a bactericidal and/or fungicidal agent, and the HEPA filter (130) is pleated while being applied against a second pleated filtration layer (150) that is arranged downstream, such as to avoid the pleats thereof from contacting one another. The conjunction of the effect of the impregnated layer and the HEPA filter enables the inhibition or the killing upon contact of all the living particles that penetrate into the microbicidal filter. The HEPA filter is held in stable application in the pleated shape thereof against the second filtration layer, such that filtering performance deteriorates only gradually.
