Having some pretty bad allergies I am sensitive to just about anything in the world. But when my allergies had been getting honestly out of hand during my own home I knew that something was going wrong, but i needed to figure out what was going on. I had a feeling it was some kind of indoor air quality issue going on in my house, and however I was not about to invest thousands of dollars into a whole home air purification system or anything even close to that until I knew for sure what was going on, after all, if a whole home air purification unit was not the answer to my concerns, then that would be thousands of bucks right down the toilet! So what I needed to do was buy myself an indoor air quality monitor! With the help of an indoor air quality monitor it would provide myself and others the answers I am looking for plus I would assume for sure exactly what in the world was happening, so I bought the indoor air quality monitor plus as I thought, it was a matter of having a super low grade indoor air quality; This prompted myself and others to invest those thousands of dollars to get a whole home air purification system. As terrible as the indoor air quality monitor was reading, there was no way a portable air purification system was going to do the trick. I called the heating, ventilation, and A/C supplier plus ordered their best whole home air purification system that I can pay for in several monthly installments over the next 4 years. So this should regular all these issues I have been having.
