Query: Huge difference from cheaper filters

I used to purchase $30 filters for my lens thinking how could the more expensive filters be that much better. I was wrong. There is a noticeable difference in the quality and picture quality when using these filters. I am not a professional photographer but I did buy 2 "L" series lenses for my Canon 50D and used these filters on them. Highly recommended
