Most other filters were too hard to slide in the unit. These fit perfect. VERY fast shipping too. Price was very affordable being on a fixed income.

Best I've NEVER had. Will replace the first one this fall. Better now? Even if they work amazing I'm never ordering again because of this stupid survey you NEED to know. Please leave me alone. Ed
