    Great price, great quality!

    Posted by Graham on Dec 29th 2023

    Have only ran this filter for a week, but the quality seems high, and the price was amazing. The only problem with ordering the 6 pack was where do I store them! Only other comment was the pleat count seemed lower than what I expected, but I was also shopping around and looking at so many filters that I may have just gotten them confused. Will report back/update the review if my rating changes!
