Get a current air filter for fresh scrub air in your home, however this is great advice for anyone who has a heating and cooling system in their house, i personally never absolutely thought that changing the air filter in my apartment was all that pressing.
I would let it go for months and months and I would not change it until I started hearing a unusual whistling sound coming from the Heating plus A/C system.
That’s absolutely the only time that I ever even looked at the air filter, and by the time I would change the air filter, the old one would be completely black and full of dust and dirt. The air could barely even get through it so the Heating plus A/C system could circulate it throughout the house. I do not know why I did this to myself, because I know that it was not great for me. I was also not great for the health of my heating and cooling system either. Now that I have figured out the air filters are more pressing than I thought they were, I change mine every two months whether they look like they need it or not. It’s easily pressing to the health of your indoor air quality and to your family to have scrub filtered air inside of your home! Your air filter for your Heating plus A/C system is the first line of defense against dust, dirt, mold, and allergens, however keep that stuff out of your air with a great air filter. Take it from me, it will make you breathe a whole lot easier.
