This is a very basic filter and a bit overpriced but it does the job. My dad said it would make more sense to buy something like this at a hardware store for a lot less. Either way, this will ensure that dust and other small particles don't get into your vacuum's motor, so check yours to make sure it's fine and clean, and if not, buy a new one. This product goes well with our Harmony (Red) vacuum cleaner (similar to the green UltraSilencer)
