I have a floor fan that I like to run while I am sleeping.
By doing this, it keeps all the outside noise from disturbing me and I sleep a lot better all together.
However, as of the last few months having that floor fan going was bothering my allergies. At first I thought maybe I needed to get some kind of portable air purification system to clean the air. But then I found out that the reason for my issues was that the fan itself was making my indoor air quality pretty bad. A portable air purification system at this point would have done me no good what so ever. So I seen the problem was the blades of the fan had all this dirt and dust caked on there from never being cleaned. It was making my indoor air quality bad! So the answer was to clean the fan blade. I cleaned the fan blades and then began running the fan again and things were a lot better. However, because the indoor air quality of my bedroom was messed up from the dirt and grime flying all over the place, I actually decided to go out and get myself a portable air purification system to run in addition to the floor fan in my bedroom. The portable air purification system actually cleaned the indoor air quality and worked great as an indoor air cleaner in general. I even used it in other areas of the house that could use some really great and top of the line indoor air cleaning.
