I'm beyond paying interest...Are you a homeowner, or is your bank a homeowner?
Filtrete 1900 Ultimate Allergen
I use those. Change every 60 days or so.
Most people probably go a lot longer (6 months ?) but I get them for nearly free so why not.
I try to remember to do it every 3 months.
I get the fabric ones that look like /\/\/\/\/\/\/\/\/ not the shitty fiberglass weave ones that you can see through.
If you spray some light weight unscented oil on the filter it will be more efficient at passing air through it and catching particulates in the air.
Me 2...I try to remember to do it every 3 months.
Not if you have any one in your house with allergies. Then they are a god send The cheap ones don't get clogged up as fast because they don't catch nearly as much and you end up breathing it in.
and like I said I get them nearly free. If you do have a dust allergy try those out they work wonders.
That's an odd thing to proclaim about home air-conditioning ventilationThe only problem with those is that they catch a lot more shit .
