Doesn’t the pre-filter reduce air flow through the filter?

It depends on the conditions. They are washable, so i change mine out and wash then every 45 days.

Do these fit 211 auto?

They are for a stand alone air purifier for your home.

Do these fit on the Blue Air 411 unit they look the same size?

I would think so. They're really stretchy...maybe keep reading the full product description; it may tell you.
