Customer Testimonials

What Departments Are Saying

Feedback from fire and rescue departments using NO SMOKE in the field.

The process to purchase and install Ward filters was easy, customer service was good, and the systems have been working as described. With NO SMOKE on the truck all the time, we do not rely on someone to connect a capture system every time a truck returns to the station. The filters require very little to no maintenance, depending on the truck’s model year. Their cost also pays for itself compared with the maintenance required for other direct-capture systems.
