Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Indiana. They belong to that state's ranking, not this one.

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