**** Customers have reported a generally positive experience with the THU9476 filter cartridge for Toto washlets, particularly when it comes to fit and odor control.

However, there are mixed feelings regarding fit and performance.

Despite these minor adjustments, many users were satisfied with the overall performance of the filter, reporting that it successfully addressed odor issues and functioned effectively after installation. While most reviewers didn't emphasize long-term durability due to the relatively short time since their purchase, there's an optimistic expectation that the filter will outlast the original one, based on its design and Construction. Some users expressed a desire for clearer guidance from the manufacturer about maintenance and replacement intervals, as not all users initially recognized the need to change the filter.
