Clean lint filter from dryer after each use. Maybe it's those awful allergies. Pollen is the cause of that and some plants are worse than others about spreading the stuff around. Plants with bright pretty flowers cause less allergy problems because they rely on insects to transfer the pollen. Plants that rely on the wind to spread the pollen produce large amounts of pollen.
Rain helps to wash pollen out of the air, but it also breeds mold, mildew and weeds.
If you are allergic to mold, avoid gardening after a good rain. Keep your garden well weeded and keep the grass cut short. Wear a mask when gardening or doing lawn work. Wear long-sleeved shirts and long pants and wash them when you're finished. Avoid gardening in the early morning or at sundown when pollen counts are highest.
