The quality of workmanship is slipping --- I found that the filter pleats do not seal against the paperboard frame on one end because they are folded over too much at the other end--especially on one of the 2 filters. This will allow some unfiltered air to flow past the assembly. Thank you for listening.
Ordering good quality filters from you has been easy, convenient and a reminder to change them. Auto-renewal is a great idea to stay on top of it. Its so important to change the filters. I found out the hard way when my ac went out years ago at my old house and the first thing the repairman asked When was the last time you changed your filter? Thats usually the cause of most problems.. Not anymore.
Our filter is not a standard size that stores normally carry. Filterbuy makes our filter and sells them at a price less than most stores standard size filters.
It's on the same level as the basic Filtrete filter. I buy Merv 11 from them and it's nice and quiet. This one is as loud or louder than the basic filtrete filters I tried. Also, they don't fit tight like the filtrete filters, I guess that 1/4 inch makes a big difference. After I use these filters, I am going back to Filtrete by 3m. Sorry guys, I figure I would give you guys a try, just didn't work out.
