Air filters come in a number of sizes, so it’s important to order the right size for your Heating, Ventilation, & A/C system, then when a machine is installed, the professional will always install an air filter & that should be the same size that you continue to use during that length of life when it comes to the machines, however blessedly, sometimes that size is out of stock, and this concern occurred Last year when I decided to throw away the outdated air filter before I looked to be certain both of us had another a single in the pantry, then i thought for sure both of us had another a single, however I couldn’t find it anywhere.
I went to the hardware store to find another air filter however they were out of my unique size.
They didn’t actually have one of the high-end luxurious air filters in that size. I know the reason is due to the covid-19 problem. The size of my air filter is rather traditional & a lot of Heating, Ventilation, & A/C systems use this style of air filter. I was surprised that the hardware store didn’t have any luxurious HEPA filters, however I expected them to be out of everything that wasn’t luxurious. I had to make a decision at this point, since I threw the other air filter in the trash. I didn’t want to go without an air filter, so I purchased the next size up which was a single inch longer. The air filter fits ok, however a lot of air is passing through. I’m going to need to buy something online in the right size & wait for the item to be shipped to my home.
