This is really the top to capture dust on all surfaces. I, who is asthmatic and allergic to dust. Swiffer did come into the house. The dust does not fly, it remains on the swifer. I use it for years. And the price is very affordable. before I bought in a store. But since this change of sign. It has become more expensive than before. And Amazon is widely cheaper. In addition I use very often. Livraion fast as usual. I highly recommend this product.
