How important is indoor air quality?

With all the issues that we had with the pandemic, most people have become hyper aware about indoor air quality.

I have friends who have even installed whole home air purification systems inside their HVAC units.

I am not saying that air quality isn’t important, but I am not sure if that was necessary for them to install. If that air purification system is guaranteed to kill 100 percent of viruses, and fully remove all pollutants from the home, then perhaps I would see the value in that. I have never used an air purification system because I believe my HVAC is efficient enough to keep the moisture or humidity levels down as well as keep my indoor air clean. The most important thing that you can do to improve the air quality in your home is to change your air filters often. The cleaner the filter, the cleaner the air will be in your home. The recommendation for changing air filters varies depending on what you use as a source. I have seen some HVAC companies advise to change the filters every 30 days, and I have seen where the recommendation is every 90 days. Of course, it depends on the type of unit you have and the type of filter you are using. If you are not sure which guideline to follow, it is best to ask your HVAC technician as they should know the type of filter that your unit uses. Personally, I change my filter every 60 days, and I have never had an issue with the air quality in my home. So, instead of purchasing an air purifier, I will just keep changing my filter regularly.
