Humidifying filter, humidifier, air purifier, Plasmacluster, compatible product

I purchased this compatible (this product) but am selling it as I did not end up using it.
I had planned to use it with a Sharp Plasmacluster air purifier.

Please confirm if this can be used as a humidifier filter for your device before purchasing.

Humidifier Filter
Width: 23.5 cm, Height: 6.5 cm, Depth: 10.5 cm

Although it is new and unopened, it has been one year since purchase, so please consider this when buying. No returns will be accepted.
