I have year round allergies and it always gets worse with dust! I always leave my windows open for fresh air, but of course there's always a downside to that. I dust the house at least twice a week on average. As soon as I got this Swiffer, I put it to use immediately!  Surprisingly, it picked up more dust than I had intended for and now I only have to dust once a week! My allergies have slowly gotten better and I will definitely  get this again!
