The filter is accessoire to fan with code 244503.
Filter fans are used to purify the air of contaminants and recirculate it. The filter attaches behind the blades of the fan to pick up dust and other airborne particles as the air passes through..

What do the two digits in an IP Rating mean?
IP rating is also known as Ingress Protection or International Protection ratings which are defined to the international standard of EN 60529. This standard is used to define the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies such as tools, dirt and moisture.
The rating consists of the letters IP followed by two digits, if a number is replaced by X this indicates that the enclosure is not rated for that specification.
IP65 = First Digit - Solids
The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (electrical conductors, moving parts etc) and the ingress of solid foreign objects.
IP65 = Second Digit - Liquids
The second digit defines the protection of the equipment inside the enclosure against various forms of moisture (drips, sprays, submersion etc).
| First Digit | Intrusion Protection | Second Digit | Moisture Protection |
| 0 | No protection. | 0 | No protection. |
| 1 | Protected against solid objects over 50mm, e.g. accidental touch by hands. | 1 | Protected against vertically falling drops of water, e.g. condensation. |
| 2 | Protected against solid objects over 12mm, e.g. fingers. | 2 | Protected against direct sprays of water up to 150 from the vertical. |
| 3 | Protected against solid objects over 2.5mm, e.g. tools & wires. | 3 | Protected against direct sprays of water up to 600 from the vertical. |
| 4 | Protected against solid objects over 1mm, e.g. wires & nails. | 4 | Protected against water splashed from all directions, limited ingress permitted. |
| 5 | Protected against dust limited ingress, no harmful deposits. | 5 | Protected against low pressure jets of water from all directions, limited ingress permitted. |
| 6 | Totally protected against dust. | 6 | Protected against strong jets of water, e.g. on ships deck, limited ingress permitted. |
