“MSU Billings has been using replacement filters from Flowmark for over 20 years. With their help, we’ve achieved a ‘5-Star’ Energy Rating for air filtration standards. Their large warehouse and custom capabilities assures us quick (often same day) delivery. Add in their excellent, friendly service, and that’s why I don’t order from anyone else! Highly recommended.”
