When I was a child making reports for school, the internet was still fairly new for average working class families. Sure, there was lots of good information out there in the mid to late 1990s if you knew exactly where to look. But it was largely the days of the wild west as far as credibility of information is concerned. I know that the concept of fake news seems like a relatively new phenomenon. In all honesty, it’s probably just the current incarnation of the weaponization of misinformation via the digital sphere. We’ve seen that behavior in varying forms for the past three decades. I try to focus on the good information on the internet instead of the bad. If I have a technical question, I often have great luck with forums devoted to the individual topics. After a bit of searching, I found this amazing forum that is full of heating and cooling professionals and experts. Often they have discussions amongst themselves about complicated issues in their field that aren’t easily settled or self-evident. But more often than not, they are there to give advice and help to people like me who don’t know anything about residential heating and cooling. I had a question regarding filters and how to find one that collects viral particles. None of the a/c filters in the store have a HEPA rating, but I found out through the forum that my filter company sells an expensive filter that is just below HEPA quality. Even at 95% filtration opposed to HEPA’s 99%, these filters are sufficient at collecting viral particles in the air.
