What i was told by an HVAC guy who was at my house to fix an issue was those more expensive filters make the system work harder as the filters limit airflow and that additional workload can cause issues.
I cannot because I’m just a goofball with a mild interest in home improvement
Wikipedia says HEPA filters became commercially available in the 1950s though so anything older than that I’d bet some beer money would benefit from a less dense filter
I wouldn’t think forced air heating systems that old are too common though tbh
We just didn’t use a filter at all in our last rental. I know it’s bad for the ducts, but the landlord was an asshole, and I wasn’t about to spend my money to protect their investment.
Don’t I want a HEPA filter for better air quality, especially if I have a dog?

physics wise that makes sense but modern systems should* be designed taking into account the air resistance of their specified filters
older or for any other reason more weak airflow systems probably do benefit from a less dense filter
*lol “should” means so little these days
Can you define older, or modern? Like how old is too old to have been designed for HEPA filters?

Nice. Thanks for the information. I’ll just keep using HEPA filters then. Speaking of which, it’s time to buy a new one. QQ
it feels like it’s ALWAYS time to replace the dsng filter
and i rent so i have to email a management company repeatedly to get it replaced 😭

good. fuck 'em. if i ever got desperate enough to replace one in my unit i’d keep the old one and put it back when i moved out lmao
