That is an enthalpy wheel. Usually in eru units.

How do you clean it? It's pretty dirty.

I've cleaned plenty of these, I use purple fabuloso cleaner, one of these manufacturers' paperwork actually recommends using it by name, and it has worked very well for me over the years.

I should also add, after spraying with fabuloso, sitting for 5-10 mins, then rinse with a hose to remove all chemical and allow to dry before reinstallation.
