Thank you for viewing. This is a Kinki Equipment H-type ventilation fan replacement filter. 1 unopened pack with 14 filters 1 opened pack with 9 filters - Total: 23 filters Size: Approximately 340mm x 245mm I purchased these in bulk and stored them, but I no longer need them as I replaced my ventilation fan. I'm offering them to someone who needs them. Although these are new and unused, I've marked them as "Like New" because one pack has been opened. Also, please understand that these have been stored at home for a long time before purchasing. I plan to ship via Rakuraku Mercari. #KinkiEquipment #RangeHoodFilter Price reduced from 3,300 yen on June 2nd.
