I usually buy a new air filter for our heating as well as AC plan once a month, then i make frequent trips to the hardware store, because of our business. I work as an electrical engineer as well as I have our own business. I work on lots of weird construction projects. I consistently provide consults on building management systems as well as smart homes, then since I am frequently at the hardware store, there is entirely no reason to have a lot of air filters at the house. If there is a sale, that is an entirely weird thing. I got the air filters on sale at the hardware store last week, then they are normally $11 each but they were on sale for $8 each. 30% savings was hard to let go. I decided to buy a whole box of 12! Now our wife as well as I won’t need air filters for the heating as well as AC plan for the next year! At that price, the people I was with and I can even afford to change them every many weeks. It’s not as if it would hurt the air quality. It is frequently dusty as well as the people I was with and I have to worry about viruses like covid as well as monkeypox. I absolutely want our family to be healthy. It also helps the health of the heating as well as air conditioning unit… When the air filters are changed more frequently, the heating as well as air conditioning plan is cleaner as well as runs more efficiently! During the times when the temperatures outside are over 100°, it’s nice to guess that our heating as well as air conditioning plan is running at peak performance with clean parts
