"General Aire 13156 Filter Media" by James white (Bothell Wa US)

Product fit as described and was easy to install. Recommend checking for mis-bonded pleats at each side - separate as required. When reinstalling new filter, temporarily clamp it to the frame using common bulldog clips. Lay each of the pleat-separating combs on its side and then rotate the piece down while aligning the tips to the folds in the media.

Everything was as advertised. The replacement filter was easy to install, and the instructions had actual words in it. I hate the modern "instructions" that only have pictures.

Furnace filter by Gene McDermott (Everett Wa US)

I am very satisfied with the filter. The only tedious part was placing the plastic fingers between the pleats.

The media seems to be fine. The plastic frame it fits in, however, with the media "combs" to hold it in place, are a w3hooe different story.while I can get the media into the frame correctly, and even get all the combs into the proper folds of the medi, I cannot get the combs to snap into the frame AND STAY THERE WHILE i INSERT THE FRAME AND MEDIA INTO THE DUCT AS THE COMBS START TO UNSNAP AND COME OUT OF THE PLASTIC FRAME AND JAM INSERTION OF THE UNIT! It is very frustrating and the unit it not fully inserted into the duct; nor can it be easily taken out of the duct. If I get it out, I'll have to glue the combs and then not be able to change the media when it gets dirty again. I need to know the cost of the plastic media holder so I can decide if it is better to buy a new one each time I buy the media. What a hassel!!!
