When stick-on air fresheners lose their odor, remove the plastic top. Soak the felt in boiling hot water for several seconds. Place it on a paper towel to absorb most of the water. Replace the felt and lid. Or just run them under hot water briefly. They last and last and last if you do this every couple days.
Attach a stick-on air freshener in your favorite scent to the top of one of the blades on your ceiling fan. Turn on the fan (use the low setting so as not to dislodge the freshener) to circulate the fragrance throughout the room.
Place a drop of scented oil on a cotton ball, and add it to your vacuum-cleaner bag.
