I have recently started increasing my air filters more often.
The reason being I noticed a sharp decrease in our indoor air conditions.
The heating and cooling in my home has always been very good, and even now the heating and air conditioner is still very good, but however, it turns out that I wasn’t increasing the air filters often enough. I used to change the air filters out about once every 6 months or so, so about twice a year, but for a while, this didn’t seem to have too bad of an effect on my air conditioning component! But once I got 2 pet cats and a pet cat, that all changed. Suddenly, all of their pet hair was suffocating my poor HVAC machine. I noticed my indoor air conditions was abruptly more stuffy and had a bit of a strange smell. I started researching reasons as to why this might happen, and a lot of people were recommending getting a whole home air cleaner, which I could consider, however I didn’t suppose my air quality was bad enough to need an air cleaning system. That is when I saw someone advise increasing your air filters out more often, and so that is what I decided to do. I bought a pressing pack of HEPA air filters, and I started increasing them out every few months. That still wasn’t enough, and so now I change the air filters out every month, and I have absolutely noticed a difference in my home.
