Has anyone purchased and used Molekule, an air cleaner, It is quite expensive, around $700. I’ve seen it advertised but it’s too pricey unless it really clears the air the way it says. Also, is anyone using a respiratory vest for boronciectasis. and if so could you make a recommendation. I’ve had mac a long time but it hasn’t progressed much;ronchiectasis , however, is making it harder to clear my lungs. I do nebulize a saline solution twice a day.
