Our whole family was suffering from allergy like symptoms after we turned on our AC. Within days of putting in our new filter we were all feeling better! No snotty, coughing toddlers! Glad I ordered two, weve already switched out the first because our indoor air was that filthy.
I've only had the filters installed for a few weeks, so it's not possible to write a detailed review. However I can say that the construction of the filters are impressive. All previous filters I've used were "flimsy" - these filters are absolutely solid.I'll write another review in a few months.
