I just finished renovating my 1965 Colonial, redoing every room into wood, fabrics, forged iron, and granite instead of the original Formica, linoleum, shag carpets, and Harvest Gold appliances. I added a few industrial pieces--steampunk, in art palance--as visual counterpoints to all the "natural" stuff. Your air cleaner is an industrial product that makes no bones about what it is, and isn't disguised with plastic to make it "neutral." The stainless mesh with the blower motor on top looks great, and I like it a lot. Sorry to blather on, but I love products that look as perfect as they work. Thanks."
SG Naperville, IL



"A great sign for your next IAOMT meeting would be a testimony of how I love how quiet the filtration system is and how it works awesome in the sterilization area running all day and you don’t even know it is on" Dr. M.W.  Greenfield, MA

"Wonderful! I'm already feeling more refreshed in the morning."  LG Woodland, CA

"I received my unit some time ago but I'm just now finding time to email you.

Wanted you to know that the unit is fantastic. I'm using it at home. I live in a rural area and in the winter when the house is closed there is frequently a mold smell in the air. Your unit quickly gets rid of that and the air is wonderful. I like having the UV as extra protection.

I feel very comfortable telling my patients about your products and hopefully some additional sales will be generated for you.

Thanks for producing such a great unit."

Regards and best wishes for the new year, W K, D.O. Santa Cruz CA
