Also named, based in another state

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of industrial filters in Missouri”
2“Who supplies high-efficiency pleated HEPA filter cartridges in Missouri”
3“I need a Missouri industrial filtration partner for a continuous-duty chemical processing line, who should I talk to”
4“Top industrial filters suppliers in Missouri for plant maintenance and reliability buyers”
5“Which Missouri industrial filter manufacturers can handle custom housings rated for high-pressure corrosive media”
6“List 20 industrial filters companies in Missouri with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
