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.

That they fit

They fit on the 211+. Colors, well don't match the decor but as the last ones didn't fit. ( From a different company)

Air filter outer covers

These work well to catch dust. The original name brand one I have is thicker but these seem to do the job. I change it weekly so the set comes in handy.

Nice set of replacement covers for the BluAir squared filter.

Great value

These are almost the same as the brand-name ones, but are a lot more affordable. Colours look good too. Works and fits well.
