For Filipinos, one of the most common fixtures you’ll see in every home is an electric fan. It’s not rare for every room to have at least one, even two in some cases. It’s not surprising, given the fact that we live in a tropical country that’s hot and humid. However, over the past few years, the need for access to clean air has sprung up. Not just because of COVID, but with air pollution, household dust, and pet hair and dander as well.
