MasterShield vs LeafFilter
Why MasterShield is better than LeafFilter Gutter Guards
LeafFilter and MasterShield were invented by the same guy, Edward “Alex” Higginbotham. LeafFilter and MasterShield are both micro-mesh gutter guard/gutter protection systems. He patented the LeafFilter micromesh in 2001. It worked pretty well for what else was available at that time, but it didn’t fix everything (as discussed below). So Higginbotham redesigned and improved his ideas, and in 2004 he released MasterShield. Because of how product licensing works, LeafFilter as a product is still around but Alex is not involved. It’s a design “dead end” so he moved on. Nevertheless, Higginbotham has worked exclusively with MasterShield since its creation and no longer views his fledgling LeafFilter to be the best available technology. For example just last year MasterShield improved its design even further by weaving copper threads throughout its mesh to fight algae and moss growth. LeafFilter has not changed its design since 2001.
