Review on 😄 Smilyan 2 Sets 116130 Filter H Replacement for Winix 5500-2 Air Purifier - Includes 2 Pack True HEPA Filters & 2 Pack Activated Carbon Pre-Filters by Ray Gist

Smilyan brand dimensions (front) differ from the original Winix HEPA filters (rear). Smilyan Hepa filters are particularly distinguished by the fact that they are shorter. There are no significant differences in width. The Smilyan carbon filter (front) is slightly shorter than the original Winix (rear). Therefore, Smilyan definitely suits the Winix air purifier. I just replaced the original Winix filters and installed the Smilyan filters as of September 2021. The quality is unknown and I will update later to see how it picks up air particles. After turning on Winix, I noticed that the sound/noise level has also dropped a bit. I'm not sure what this means or causes, but only time can judge the quality of the Smilyan brand to see how much Smilyan filters collect after a year compared to original Winix filters.
