This is a premium micro-carbon CM2α cartridge for the TRIM ION HYPER. I haven't used it much, but when I checked its operation on April 19th, it had 3 bars remaining, one less than the full 4 (see photo 5). It might be closer to 2. I capped it after draining as much water as possible. Includes shipping via Mercari. Thank you. TRIM ION HYPER Water purifier Water filter
