NOTE: DUE TO A REDUCED WORKFORCE BECAUSE OF THE VIRUS AND BECAUSE 1/2 INCH FILTERS HAVE TO BE CUSTOM MADE, WE ASK FOR YOUR PATIENCE. THERE IS ABOUT A ONE WEEK LEAD TIME ON THESE FILTERS.


NOTE: We know of no other company that makes 1/2" high quality pleated filters. If you find another website, it is probably one of our websites.

DON'T SEE YOUR SIZE, DON'T DESPAIR - WE CUSTOM MAKE ANY SIZE

How often should a one half inch (1/2") filter be changed?.....There are many variables that go into answering that question. Most important is how often you run your system, how dusty your neighborhood
is, the size of the duct system, the size of your home, etc, etc.....

Let's face it, no one is going to sit there and figure out all those variables, so the most logical answer is "look at your filter after a couple months and use your judgement. If you want a rule of thumb, then I would say every three months.
