Someone posted a thread about difficulties with incense smoke and I wanted to offer a practical solution that is used here locally. Buy and use a mask/respirator that will filter out the smoke. The mask/respirator need not be large and industrial looking. Think of a traditional looking surgeons’ mask. Not distracting to others.
Someone in my parish (we use incense many Sundays) has asthma and COPD. She literally used to stand outside and would watch the Mass through a window. I bought her a respirator through Amazon.com, she gave it a try and it allows her to sit with the rest of the congregation.
She obviously removes it for communion and it does impact her ability to sing, but otherwise the respirator has been a godsend. Not only does it keep the smoke from aggravating her asthma and COPD, it also put a stop to anxiety she felt at the potential of an outbreak.
