I never realized how helpful air filters were as a landlord.
Sure, as a landlord, I definitely understood why air filters were important for an HVAC unit.
When you own multiple houses in a city, you quickly begin to realize that when you do not change the air filter in your HVAC unit, you are definitely going to start experiencing problems with your HVAC units. The air filter prevents dust from coating all of the parts within your HVAC unit, and if you change your air filter, you will find that your HVAC unit actually breaks down less often than if you ignore the air filter in an apartment. Also, by changing the air filter when you are supposed to, you can help your tenants to not get sick as often. By forgetting to change the air filter, you are forcing your tenants to breathe in nasty air. However, now that I have been a landlord for a long time, I have discovered that the air filter can do something even more useful. In my house, I have a policy that states that you cannot smoke inside. However, I can tell that people smoke inside. First of all, the smell gives it away, but since people will claim that it is because of their clothing, I cannot use that to prove the smoke. However, by changing the air filter in the HVAC unit regularly, I can tell if they smoke inside. When you smoke inside, it changes the color of the air filter in your HVAC unit. People that smoke physical cigarettes turn the air filters yellow, and people that vape turn the air filters black. This is a sure way to see if someone is smoking. Who knew that air filters could be so helpful?
