Any moving air of decent volume will keep away flying insects, or rather, make it less likely they can land on your skin. Misting could help, too. I am sure this fan can do the job.
It's a very versatile fan, both on stand and tabletop (or floor). I hope it will be perfect to run on battery if there is a summer power outage and there won't be air conditioning. I'll need a fan to survive! Plus, I can recharge it in the car if power is out for a day or two instead of a few hours. Possible life saver!
I so enthused was about to order it (in white) as the TSV but I checked and saw it for $10 less at Costco, same free shipping. I ordered from Costco not just for the big $10 savings, but because it would be so much easier for me to return it if defective or doesn't meet my needs, than to repackage it and ship it back to QVC and have the long wait for a refund.
I think it's one of the best appliance QVC has offered and I hope everyone gets good use from their new fan.
