The filter is of very poor quality, the workmanship is very rough, the ceramic is yellowish, the filter arrived cracked. I didn't want to bother with returns, I just bought the brand of duster I'm used to and the difference in quality control is very noticeable. See photo, this is the left filter (grey plastic), the other good one is the right one (white plastic). Although I have not installed or tested it, I would not recommend this filter due to the overall difference in quality.
