Ordering is easy and it was shipped to me in a couple of days. Replacement of the filter is relatively easy and I am satisfied. By the way, I replaced my furnace in February and the air has never been cleaner, verified by my Ecobee thermostat and the lack of dust on the furniture, of which my wife and I are absolutely elated.
