04Who makes this

We make what we sell.

Think Crucial started in 2007 at a family vacuum repair shop. Today we're a U.S. company in Hollywood, Florida, making aftermarket filters, bags and parts built to fit the machines you already own. Most people can fit the part themselves. They just need the right one, and a way to check it first.
