Customer Testimonials

Hear what some of our customers are saying about us…


“My utility bills have gone down $40 per month this summer.”
- Mike Crampton

“Being a professional engineer I must admit that I was somewhat skeptical the benefits would be as significant as your company’s literature claimed. However, benefits were greater. Wife-able to get a good night’s sleep–cleaning a snap–wash with garden hose–good as new. I recommend “ULTRA” to everyone–Engineering associates and my children.”
- Crews Engineering, Charles L. Crews, President (Tulsa, Oklahoma)

“Not only has dusting virtually ceased, but it is almost non-existent! Even on TV and computer screens.”
- R. D. Marcum

“Please understand I don’t push products-write letters-this is an exception. Despite high pollen and dust levels associated with summer and nearby construction of a major highway, we have been breathing much more comfortably than normal-In particular, my children, who have asthma have been sleeping more soundly. Thanks for a high quality product.”
- Dr. Mark D. Weber (Tulsa, Oklahoma)

“Remodeling work done. Very impressed and amazed. Construction dust stayed in the work area and not thru rest of house.”
- Peggy Gallagher
