Most of us treat laundry as a set-it-and-forget-it task, but there’s a small detail inside your washer that makes a surprisingly big difference: the filter. This hidden component catches lint, loose hair, and leftover detergent during every wash. When it’s ignored, buildup slowly forms, leading to stale smells, residue on clothes, and unnecessary stress on the machine itself—all without any obvious warning at first.

The fix is refreshingly simple. Spending less than ten minutes once a month cleaning the washing machine filter can dramatically improve how your appliance performs. A clear filter allows water to drain properly, which means less moisture and soap left behind after each cycle. That small step helps your clothes come out cleaner and keeps unpleasant odors from taking hold inside the drum.

When a filter becomes clogged, the effects tend to snowball. Wash cycles may take longer, the machine can grow noisier, and cleaning results may decline. To prevent this, start by turning off and unplugging your washer. On most front-load models, the filter sits behind a small panel near the bottom front, while many top-load washers conceal it inside the drum or along the agitator—your manual can help pinpoint the exact spot.

Once you’ve found it, place a towel underneath, gently remove the filter, and rinse it with warm water. A soft brush works well for stubborn debris. Wipe the filter housing clean before reinserting it. For extra freshness, run an empty cycle with a cup of white vinegar every few months to break down residue and neutralize odors. This quick routine not only keeps laundry smelling clean but also helps extend the life of your washing machine with minimal effort.
