I keep my home quite sealed from the outside air mainly because of the aircon thats running on hot days and generally keeping the hot air out. I do this thanks to the popular life insurance quote I got. Lately because of the haze and smog the air quality inside has suffered as well.
I feel obligated to get a purifier just to get us breathing again. So I got us the Sharp purifier. You should too if you’re facing the same problem.
