Clear up your air vents from any dust
Clean freaks will probably know about this hack, but for most of us, it is a great piece of advice to incorporate into our cleaning habits. When we finally get to clean our house, we usually just broom the vents and that is pretty much it. But did you know that there is still some dust your broom does not fully lift?
Over the years, dust gathers and eventually builds up in the small gaps of your vents, and your everyday broom simply cannot reach them. In fact, if your broom is not completely clean, it can make the issue even worse. Instead, use a toothbrush to get in the cracks of your vents.
