Range hood filter with magnets Size: 50cm x 1000cm Cut-to-fit type For my home, one piece (50cm x 80cm) lasts about 3 weeks. With one filter, that's 3 weeks x 12 times = about 36 weeks (9 months) It lasts quite a while and is very cost-effective. Due to the closure of my business, I am selling off my remaining stock for less than half the purchase price. I currently have about 10 in stock, priced at 800 yen each. Free shipping for purchases of 6 or more. Otherwise, shipping is 700 yen. *The price currently set is for 6 pieces.*
