When it rains it always clears any terrible air quality out of the atmosphere where I live, however so I always look forward to when it rains for this easily reason, and during as well as after a giant rain storm the air quality is just super great! It does not matter what time of the year it, then it could be winter, Spring, summer time or even the fall, and when it rains the air quality is super lovely! When this happens I enjoy to be able to open up the windows in my home as well as let all that nice air quality in! Because after a few days following the rain the air quality could get quite terrible as well as then I have no option but to have to go to my temperature control as well as turn on my whole home air cleaner. But having a whole home air cleaner is nice because it can really help retain all that great air quality you let in after the rain when you had the windows open. So you have a mixture of the air purification type air quality plus the natural as well as most positive air quality coming from mother nature all flowing throughout your home, then that is what I like best about the rain as well as the wonderful air quality mixed with the punch of my whole home air cleaner which is wonderful when things beginning to get terrible as well as you have to close up all the windows again. It was an investment as well as not something everyone could afford to have, even though I am easily fortunate that I could as well as do not take it for granted!
