After spending most of my time at home for a year, I found that I was very congested. It turns out that I have a strong allergy to dust now. Even after visiting an ENT and trying different medications, there was no relief. I was miserable because I couldn't breathe.

Someone suggested an air purifier. I did some research and Blueair was highly rated. It was worth a try.

Within a few days, I noticed that I was no longer stuffy and could finally breathe!

These gadgets are great. I plan on buying a few more for the rest of the house.
