Common Questions
Is anyone using this on vent registers for a central heating and cooling system?
I have done this in my work area and after 3 filters over 2 years, I can tell you that they absolutely do trap all kinds of nasty stuff in the A/C air stream.
I have to cut to fit the 3M ac filters, but how do I attach them to the screen filter?
You can fold it over both sides so you can slide the filter frame back in and it's easy to remove when you need to clean or replace the filter.
Is the above price for one unit or 12 units in one pack?
The price is for a piece of filter that is 15 inches by 24 inches.
Does the shiny side face in with the air entering the dull side and coming out the shiny side?
The air is pulled from outside and forced through the machine, like a fish filter.
What is the merv rating for this filter?
The box says it's certified to ULC Std S111 and that it complies with UL Std 900.
