Re-Starting COVID Precautions, Mask Recommendations?

Hi folks. So I admittedly had fallen off the wagon as far as precautions go this summer. However in light of this new wave along with having two chronic illnesses (psoriatic arthritis and fibromyalgia) that I take immunosuppressants to manage, I am going to start masking again. especially at work, as I am a substitute elementary school teacher and kids are walking Petri dishes lol. I am new to N95s and ordered a sampler pack with various types to try out but am wondering what everyone here finds comfortable. I am definitely feeling a bit anxious as I know I will likely be the only one masked in most situations and nobody in my family or friend group are taking precautions any longer. However, I am hoping for the best. Any recommendations would be so appreciated! Stay healthy, everyone.
