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.

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.

I Like These

Easy to clean and change. You can add some color to the room or tone it down. Filtration is good and does not appear to impede air flow.

Bit thin

They're OK they're a bit thin they're usable, but the ones that I originally purchased were much thicker

They work

A little thinner than the originals that came with it but they work fine and no complaints on the price. Another bonuse is that you can change colors from time to time. I haven’t tried to wash one yet (I always just throw the originals in the laundry) but I don’t expect any problems.
