Is there such a product out there that could easily be mounted to a
window to send in a constant flow of fresh air?

This would be great for cold areas like here where its not a great
energy saver to open the windows when its always 10 degrees in the
winter.

Im thinking of a device that filters (hepa filter) the air and warms
the temperature of the air to room temperature and then flows it indoors.

I have alot of allergies / chronic headaches and crap like that. If I
dont open the windows once every 3 days the stagnant air builds up and
I feel like crap again. Once I get fresh air in again I feel much
better.

Im not even sure if such a product has even been invented yet? If
not, someone might be able to get rich trying.

Our AC/heat pump has a gismo that can be adjusted to change the amount
of fresk, outdoor air taken in. Mebbe your furnace has the same.
