Cycle Air - logo design for a new HVAC air filter company (environmentally friendly)

This is what Cycle Air was looking for in their logo design

We need a logo design for a new company called "Cycle Air" who make environmentally sustainable air filters for HVAC in the US and Canada.
The logo should communicate a sense of environmentally conscious, recycled, air and purity theme. No specific colour requirements yet but leaning toward green and/or blue and/or black and white, though fully open to interpretation. We hope the logo will look good in both colour and black & white as sometimes it will be in B&W.

The logo itself can say "Cycle Air" and "Cycle Air Filters" with the word "Filters" being secondary (and less of a focus) so it should work both with and without the "Filters" word. Read more
