Helllo!
I am looking for the best air purifying trees for Zones 7a or 7b? All I can find online is about the best indoor air purifying plants. (Yes, I understand all trees will purify but I'm wondering if there is a list of the air purifying champs?)
Thanks!

I'm hoping one of these may help you, or be a jumping-off point toward the info you need...

https://www.quora.com/Which-plant-or-tree-purifies-air-the-most
several trees are mentioned, though the brief list seems like it'd be climate limited

I’ve had good results when seeking many answers to tree-related questions on this site:

These people definitely know the tree topic — and since they’re active both in Africa and in the UK, they likely would have knowledge for a zone with conditions like yours
http://internationaltreefoundation.org/

BTW, I'm in zone 6, with the forest quite near, but still near our house we've planted some trees (such as a hard-maple cousin to sugar maple), a weeping willow, and some spruces that I'm glad we have for shade and for the influence on the air.
 
Whatever. Here's a tiny ad:
