My single mother bought this townhouse 05 I grew up in this house live here till now and I just found out yesterday. There is a air filter in the furnace. Yes you got that right 20 years of the same filter. I just changed it today. Oh my God I can’t believe we’ve been breathing this air for 20 years

That is a structural air filter at this point.
Is your mom still single?
I can’t believe your furnace kept working for 20 years.
That’s absurdly clean for 20 yo filter
Show us the new one, come on…
I’m glad you found it. You’d be surprised how few people bother to change their filters. And I’ve seen plenty of places with zero filter.
Setup an Amazon subscription and every time it arrives that’s your reminder to change it out. I’d honestly forget if I didn’t have it setup.
After 20 years they automatically allow small gap bottom left of the filter for emergency situations.
I have the smae filter in my furnace.. Uou can just hose it off and reuse it..
20 years? Did ghosts come flying out when you pulled out the filter?
Phil Leotardo went in the same time as that filter
>I can’t believe we’ve been breathing this air for 20 years
Thanks to the filter, that’s what you haven’t been breathing for 20 years.
Don’t feel bad. I used an air purifier for a year before noticing the filter was still wrapped in plastic.
That’s how my computer tower looked when I cleaned it last time
This could be in a museum
Thanks for posting this. I am a single mother and new homeowner. Had no idea there was a filter in the furnace… also not sure I have a furnace. I have two new HVAC systems in my attic and live in AZ so heat isn’t necessary but I think I have it? Idk … off to do some digging so my son doesn’t make a similar post in 20 years 😅
How many filters are in a home? I bought my house 5 years ago and I’m a single female. I count 3. Furnace, fridge and dishwasher.
As an hvac tech, that’s the worst I’ve seen but I’ve seen plenty that are nearly as bad
Why is your HEPA filter made of dirt?
Wow!! I wonder how much extra the furnace was costing you to run, vs what it should cost….I’m assuming the furnace would have to work harder, to get the air where it needs to go?(!?) Anyone able to hazard a guess?
This is a good reminder to people to check your filters!
Kinda looks like a giant chocolate bar 🤤
Wait, 2005 wasn’t twenty years go because that would make me 40. That can’t be right.
Load bearing filter
Yeah, that’s called child abuse.
In 20 years you have never had the furnace inspected or cleaned and they never said anything to you?!
More radiation in that “filter” than Chernobyl
I mean there probably wasn’t any air moving through that anyway. Can’t breathe the bad air if it’s blocked off.

What make and model is that furnace!!! I’m buying stock in that company.
Now that you swap out your furnace is gonna malfunction lol
