I have a little trick I sort of use to think when it is time to change the air filter in our central heating plus A/C system, however and it all comes down to the toilet lid in our bathroom! I think that sounds a bit goofy, then but because of how it consistently happens, if the lid of our toilet ends up getting a bunch of dust plus dirt on it, after that I think it is time to change the air filter of our central heating plus A/C system, then this is because when the air filter is dirty, it starts blowing the dust plus dirt in small particles right out of the air vents above the toilet seat.
This was a enjoyable way to remind myself to change the air filter of our central heating plus A/C program as well.
Before I figured this trick out, I periodically would go a few months or more separate from decreasing the air filter of our central heating plus A/C system. This began causing some complications around our apartment when it came to sneezing plus other allergic reactions to the awful air quality! So in a way, I am thankful for our toilet lid! One morning I went into our bathroom plus had noticed that our toilet lid was particularly filthy plus I knew something wasn’t right because I had just cleaned it. That was when I figured out it was the air vents blowing dirt plus dust plus from that morning on, I ended up using this as a sign plus reminder to change the air filter in our HVAC system!
