Genuine Roomba filter (3 filters x 2 packs). I am selling these because I no longer need the accessories I bought in bulk when I replaced the main unit. Unused, brand new. Compatible models are: ・Combo j9+ ・Combo j9+SD ・Combo j7+ ・10 MAX Please confirm before purchasing to ensure compatibility. The official price is 4,370 yen for a pack of 3 filters. Bonus: One mop pad (unused). This is one that came as a spare when I initially purchased the unit.
