PurAyrLogo Design Contest

Thanks everyone for the great submissions. Our team has compiled some feedback below. We appreciate your efforts to improve the submissions:
9+10 - We like the color combination. The use of the circles could hint at air/ozone. We don’t like the way the circles replace the stem of the y or the horizontal line of the A – it feels a bit artificial and weakens the strength of the letters. Is it possible to see a version in which the circles go from U to Y in a semicircle (or something similar, without the flowing out of the letter). It could also use a heavier weight font.

6+7 - There is something we like about the flow/balance of the font as well as the colors. Unfortunately the icon in #6 does not communicate appropriately. One variation on this might be to play with 3 circles (3 oxygen molecules) in some way, maybe in upper left in blue?

30- We like the airflow idea turning dirty to clean. We would like to see some letter font variations and air stream variations.
