I use the RZ Mask. Worked great when there was tons of wildfire smoke in my area. Outside of that incident, I don't use it all the time out of laziness and currently just use it for longer trips. I feel like it helps with the general nastiness on the highway so it'll probably help with the allergies. They have lighter-weight, more breathable versions of both the masks and the replaceable filters.
