AIRLOVE is for everyone concerned with the state of their health, it could be just the thing you need especially:
If you have respiratory issues or allergies
If you live on a busy street, near a construction site, or by a hospital
If you live in a home with pets, smokers, candle enthusiasts, etc...
If you frequent crowded environments at your workplace or on public transport
If you simply want another layer of protection in addition to your mask — when going to the store, eating at a restaurant, or even walking your dog
