Having fog in my local area is not something that happens every single day. As a matter of fact it is rather rare that we have fog! But lately we have been having fog and as a result the air quality has been totally awful. It has been such awful air quality that several have gone out and bought either portable air cleaners or even made investments into whole home air cleaners. I absolutely was one of those people who invested in whole home air cleaners. I figured because the air quality was so awful it would be the best thing to do, however home air cleaners are legitimately overpriced. But I made the investment because we do have awful air quality at particular times of the year and my flu symptoms can act up real bad, then having awful flu symptoms is what made me react awful to all the fog that we were having. And the whole home air purification idea was the best thing to get. Sure I am going to be paying it off for lord knows how long, but I know it was well worth it. It was better to have a whole home air purification unit to clean the indoor air pollen levels of my home rather than have no air purification or a cheap portable air purification unit and make it so that the air quality was not so good. I am quite happy with my whole home air cleaner. It helps with the fog that we have.
