There are other models on amazon as well that have more structure like this: WoodyKnows Filter

They have filters you can replace & rinse out. Not sure how I feel about the frame being in my nose all day though.

First Defense Nasal Screens, 7-Sets Per Pack https://www.amazon.com/dp/B004KQF9QA/ref=cm_sw_r_cp_api_i_UzTEDb5VV5HZC

Try these. I don’t have it nearly as bad as you but these have helped for during the day. It helps keep crap out and inhaling doesn’t hurt as bad.

These are another option.

WoodyKnows Nasal Mask, Allergy Relief, Reduce Pollen, Dust (Round Nostrils, Multi-Size Pack (4 Frames)) https://www.amazon.com/dp/B00SHELUP0/ref=cm_sw_r_cp_api_i_QCTEDbCFMQ0F4

The advantage for me was having a runny nose I could pull these out quickly, wipe, and reinsert.
