Air filters are able to come in a number of sizes, so it’s important to order the right size for your Heating and Air Conditioning system.
When a device is installed, the professional will always install an air filter and that should be the same size that you continue to use along that lifespan of the machines! Unfortunately, occasionally that size is out of stock.
This concern occurred Last month when I decided to throw away the aged air filter before I looked to be certain we had another 1 in the pantry! I thought for sure we had another 1, however I could not find it someplace. I went to the hardware store to find another air filter but they were out of my own size. They did not even have 1 of the high-end extravagant air filters in that size. I recognize the reason is due to the covid-19 outbreak. The size of my air filter is rather traditional and a lot of Heating and Air Conditioning systems use this genre of air filter. I was surprised that the hardware store did not have any high cost HEPA filters, however I expected them to be out of everything that wasn’t extravagant. I had to make a decision at this point, because I threw the other air filter in the trash. I did not want to go separate from an air filter, so I bought the next size up which was a few inches longer. The air filter fits ok, but a lot of air is passing through. I’m going to need to buy something online in the right size and wait for the item to be shipped to my home.
