Embodiment Construction

[0029] refer to figure 1 , the prior art filter 1 comprises a sequence of sequential filter layers along the direction of the airflow, this sequence of sequential filter layers consists of the following layers: non-woven filter substrate 4, non-woven polypropylene or Polyether layer 3, and non-woven polypropylene layer 2.

[0030] The non-woven filter substrate layer 4 includes an inner layer made of polyethylene terephthalate and an outer layer made of polyamide, and the filter substrate layer 4 is positioned on the side where the air to be filtered comes, by Arrow F is shown.

[0031] Furthermore, said nonwoven polypropylene layer 2 is obtained by a "melt blown" process. The nonwoven polypropylene or polyether layer 3 is "carded" in that it is obtained by a process of carding.

[0032] It is also known to insert an activated carbon layer between a nonwoven polypropylene or polyether layer 3 and a nonwoven filter substrate 4 . The activated carbon is capable of absorbing ...

Abstract

The invention mainly relates to an antibacterial filter which comprises at least one filtration substrate (11) and is essentially characterized in that the filtration substrate (11) is impregnated with at least one organochlorine compound. According to an advantageous embodiment, the organochlorine compound is triclosan having a content by weight, relative to the total weight of the filtration substrate (11), which is greater than 0.05%. The invention also relates to a system for the air ventilation of the passenger compartment of a motor vehicle, in particular to an air conditioning system, comprising at least such a filter (13).

Description

technical field [0001] The present invention mainly relates to an antibacterial filter. [0002] The invention also relates to a cabin ventilation system of a motor vehicle comprising such a filter. Background technique [0003] Motor vehicle compartment ventilation systems, such as air conditioning systems, involve the filtration of air entering the compartment. [0004] Increased air pollution increases the exposure of air conditioning system filters to dust, pollen, bacteria and fungi, which creates odor and allergy risks for occupants in the vehicle cabin. [0005] Bacteria present in the air are thus again trapped in the filter. In fact, the humidity and temperature conditions in the filter favor the growth of these bacteria. [0006] When the filter becomes full of bacteria, there is a risk of releasing these bacteria into the cabin. [0007] Treatments exist to prevent bacterial growth, but these systems cannot avoid all allergy risks or odors for the occupants of...
