<p>PURPOSE:To obtain a flexible filter giving low pressure loss against laminar flow or turbulence in practical use by forming the filter having a three- dimensional knit as the core comprising polygonal net cells with air-diffusible partitions. CONSTITUTION:The filter base material 1 is a three-dimensional knit comprising polygonal net cells 7 having air-diffusible partitions 5 and one side of the filter base is closed with a net-like sheet 3. The cells 7 are filled with an absorbent 6 such as active carbon. The other side of the three-dimensional knit 1 which is not closed is covered with an air-diffusible sheet 8. Thus, the obtd. air purifying filter is flexible and gives low pressure loss against laminar flow and turbulence in practical use, which realizes an air purifier of low noise and large air flow.</p> |
