HEPA H13 + 活性炭フィルター（チューブ用）

After three months of use, the air in my bedroom feels noticeably cleaner and less dusty, especially since the activated carbon layer is doing a great job with odors. It clicked into my Duux Tube perfectly and took less than five minutes to swap out.

The activated carbon layer really makes a difference in reducing cooking smells, and the HEPA H13 feels like it’s catching more dust than the old filter did. Installation was straightforward, just a quick swap and it was ready to go.

After a few weeks of use, I can already smell the difference in the air compared to the old filter—the activated carbon layer is doing a solid job on cooking odors.
