The filters seem to be good. I really enjoy that, but I need to change the deliveries. I am sitting on top of five filters now.

Work great. Change quarterly and have checked before first use each year, Techs say systems are very clean.

Filters are delivered automatically once a year. We change them at the start of each quarter of the year. We have our heat and air checked before using them. Techs tell us they are very clean and should last for a while. Great news for 20:year old systems. They say the filters really help.

I ordered four filters. I got what I ordered on time, and they fit my furnace nicely. I labeled them with dates so I know when to change them. Good to know I'm all set for the next year.
