This may sound different and strange, but I am sort of allergic to baby powder.
I don’t use it personally, but my wife does.
Because of this, we got a portable air purifier for our bathroom. When she takes her shower every morning, she knows to turn on the portable air purifier after she’s done, so it clears out the room of the baby powder in the air, which otherwise makes me sneeze like crazy. The portable air purifier we got actually makes it to where the baby powder doesn’t bother me or make me sneeze. However, one time, when the portable air purifier wasn’t working right, I started sneezing like crazy again after my wife took her showers in the mornings! It was at this point, we decided to go for the big air purification method. That was to invest in a whole home air purification system. Yes, that may sound a little drastic for something as silly as baby powder use, but believe me when I tell you, it was well worth it! Ever since we got our whole home air purification system, we both have noticed that the indoor air quality in our home is much better than it used to be. My wife herself had allergies in the Summer. But guess what? Ever since the installation of the whole home air purification system, her allergies are now gone! What started out as a little allergy over baby powder for me, ended up fixing a big problem with my wife’s Summer allergies! Praise whole home air purification systems is what I say!
