What models does this filter replace?

This filter replaces X6670 for Lennox Model HCF16-10, HCC16-28.

What is the efficiency rating of this filter?

The efficiency rating of this filter is MERV 11.

Does this filter improve air flow and lower static pressure?

Yes, this filter has better air flow with low static pressure, which also extends furnace life.

Will these filters work if the air flow is on the right side?

Yes. These filters work no matter what side the air flow is from simply by flipping them around.

Can these filters be recycled after use?

I wouldn't recycle, they're covered in dirt. Put in the trash. You could separate the cardboard from the filter and recycle that cardboard though. Do it outside or they'll be powdery fine dirt dropping off.

How often is it recommended to change these filters?

The product says annual but, like engine filters, it would depend on usage. Personally, I pull it 3 or 4 times a year and knock out loose particles. If it's really clogged, I replace it.

What is the airflow capacity of these filters in cuic feet per minute (CFM)?

My usage is in a 1800 cfm furnace and air conditioning system with no problem. I suspect that it will handle over 2000 cfm easily as they are well constructed. They are designed for furnace and air conditioning systems but not for test wind tunnels.

Can this filter be used in my lenox gmpp-36b-070?

Doubtful, unless the filter cabinet was modified. Your furnace is designed to use a 16x25x1 inch filter. The filter you are looking at is 5 inches thick and designed for an AC air handler.

Do these filters have the 2 'foam runners' on the top and bottom?

The foam runners are on specific filters. Please contact us and we can assist you further.

Where are these filters manufactured?

The filter says 'Product of Mexico'.
