Best bang for the buck they are perfect and the price is unbeatable. These were a great value, which is why I purchased them. I didn't want to have to wait for my filters to dry every time I want to replace. It could keep you from having a weak vacuum. Clean filter and clean air... This vacuum is lighter and honestly is picking up way more dirt. The customer service that comes with these filters is great. I would buy from this seller again based on the nice card in my box.
