When you change your cooling system filters all of the time, that is only more money that is being spent because then you will have to buy new ones pretty soon.
So I did not change our filters that often! Often enough to make sure my cooling unit didn’t overheat, not often enough where I felt it was a waste of money, I also got the okay cooling system filter brands, rather than HEPA filters, since I think they should do just fine! Anyways, I ended up changing our mind when I took out the old dirty air filter. Usually the air filters are pretty gross, as expected, but this time the HVAC filter was easily disgusting! As I was taking it out, literally balls of hair, lint and who knows what fell out! It was also slightly damp which only added to the disgust factor. I looked and I couldn’t even see through the filter it was covered in so much stuff. I decided after that that I will go ahead and begin changing the air filters out a bit sooner. Not only is that terrible for the cooling system unit, but it’s just gross to have in the house and going through the air! Maybe eventually I will even update to the HEPA filters, however I am trying not to spend too much money on filters or the heating and cooling system unit! That air filter was the last of the stock I had, so I had to visit the nearby heating and air conditioning store and buy a new stock. I went ahead and purchased one HEPA air filter to give it a go and see how it does, maybe it is worth the money.
