I am sensitive to many paints. I like BM Regal better than Aura ... haven't used Ecospec. Aura's pretty thick and thus, I found it to have more irritating fumes than Regal, even tho it's supposed to be lower VOC. But what irritates me could well be different than what irritates you. Do you know what chemicals work best for you? The BM website should have product safety data sheets - you could compare the chemicals in Ecospec to Aura to see the differences in paint. By way of reference, Sherwin Williams paints are awful for me, and I don't like any glaze extenders. If you are similar, be careful with Aura. Many (not all) BM dealers have $4 sample jars of aura you could try. have fun!

I haven't used Aura, but I have used both Regal and Regal Select in the past few months. The Regal Select is thicker--and so I prefer it. Fewer drips and less spattering with the roller! I think it does cost more, though.

Hire a local designer. Look under the Find a Pro tab.

We used BM Aura matte finish paint in our guest bathroom before the bath and spa version came out, I think. We also used the bath and spa version, also matte finish, in our other two bathrooms, which we reno’d after. We used the matte finish on all the ceilings (mixed up in Super White), and satin finish on all the base molding (same colors as the walls). No issues with any of them. Well, a minor issue; if you use any products containing benzoil peroxide, and any of it splatters onto the walls, it will leave bleach-like or discolored spots. It probably does this with any paint though.
