It has been a real hassle for myself and others trying to sleep the last several months. The town I moved to has the worst air quality at certain times of the year, & at night it is even worse when the wind is blowing in a certain direction. I have tried everything from insulating the walls to even blocking off the windows completely. And that wouldn’t even work. The thing I finally found that did work, & I wish I had thought about it sooner, was to get a portable air cleaner, but with a portable air cleaner I was able to completely scrub the air quality within our dining room while I sleep. It would not matter which way the wind was blowing or how strong it was blowing. The portable air cleaner was completely removing the exhausting air quality & it was like I had no exhausting air quality at all! I absolutely began getting really nice night sleeps once again. The portable air cleaner didn’t cost myself and others too much. I was able to get a single of these things for a little under a single hundred dollars on sale at our local hardware store. I was not expecting to find a single of these portable air cleaners at the local hardware store. I knew they sold portable heat & cooling system products, however did not think they also sold portable indoor media air cleaners as well. I really lucked out i’d say. And I highly suggest a portable air cleaner to anyone out there that has allergies or air quality complications!
