TOTO Washlet S7 and S7A Deodorizer Catalyst Filter FAQ

How does the TOTO Washlet Deodorizer Filter work?

When you use the bidet, a built-in fan automatically pulls air straight out of the toilet bowl before odors can escape. This air is forced through the activated carbon filter, which chemically traps and neutralizes odor molecules on contact. Instead of masking smells with artificial perfumes, the system completely destroys them to leave your bathroom fresh and fragrance-free.

What is the THU6587#01 filter made of?

The TOTO S7 and S7A deodorizer catalyst replacement filter uses activated carbon media designed to absorb and neutralize odors as air passes through the Washlet deodorizing system. The porous carbon material helps trap odor-causing particles, providing effective, fragrance-free odor control without the use of sprays or chemicals.

How often should I replace the deodorizer filter in my TOTO S7 or S7A?

The Washlet deodorizer filter should be replaced when odor control performance begins to decrease or according to the maintenance recommendations for your specific model. Over time, the activated carbon material becomes saturated and less effective at absorbing odors. Replacing the filter helps restore the deodorizer’s performance and keeps your Washlet operating as designed.

How do I know if my Washlet deodorizer filter needs to be replaced?

A TOTO deodorizer filter may need to be replaced if odors are no longer being reduced as effectively as they were when the unit was new. Other signs can include the deodorizer fan running normally but bathroom odors lingering after use. Replacing the saturated activated carbon filter helps restore the deodorizing system’s ability to absorb and neutralize odors.

Why is my Washlet deodorizer fan running but still not removing odors?

If your TOTO deodorizer fan is running but bathroom odors are still noticeable, the deodorizer filter may be saturated and no longer able to effectively absorb odors. Replacing the THU6587#01 filter restores odor control performance and helps prevent dust and debris buildup inside the deodorizer fan system. 

Before ordering a replacement, verify the model number, as older models such as the S550e, C2, and C5 require different deodorizer filter part numbers. For additional assistance, contact the Plumbing Deals team using the chat feature, email at contact@plumbingdeals.com, or call at 888-682-5956!
