I was having some pretty bad air quality issues in my home the last year. After doing several bits of troubleshooting, I found that the first step I should do is to get the ductwork of my central heating and air conditioning system cleaned. Cleaning the ductwork of the central heating and air conditioning system I figured was the issue. I found this out by someone telling me that when you do not have the ductwork of your central heating and air conditioning system cleaned on a semi regular basis, it can create bad air quality in the home. So this was the first thing I did. I expected that after the local heating and air conditioning company sent a certified heating and cooling specialist out to do a full on ductwork cleaning, that my indoor air quality would be better and my issues would be nothing but a distant bad memory. However this was not the case. It turned out that the ductwork of my central heating and air conditioning system was not the problem. The problem was actually the neighborhood I lived it. So the only way I could fix the indoor air quality would be to get some kind of an indoor air cleaner. The best one would have been a whole home air purification system. But whole home air purification systems are a bit out of my price range. So I had to settle for getting a few portable air purification systems. The portable air purification systems actually did the job!
