Dry similar fabrics together.
It will be kinder to your clothes. Lightweight synthetics dry quickly while natural fiber clothes, like denim, take much longer.
Don’t overdry clothes.
Hanging clothes out while they’re still slightly damp can reduce the need for ironing (a big energy user). Save energy by using your dryer’s automatic dry feature rather than the timer setting.
Dry two or more loads in a row.
This takes advantage of the heat that’s still in the dryer from the first load.
Clean the dryer filter after each use.
A clogged filter restricts air flow, reduces performance and may be a fire hazard! Also be sure to clean out the dryer exhaust vent at least once a year and make sure the flapper on the outside hood opens and closes freely.
Dry full loads, but avoid overfilling.
As with the washer, running the dryer with small loads wastes energy. For best performance, air must be able to circulate freely around the clothes.
