Quick answer: Metal mesh range hood filters pop out and can be washed in hot soapy water; charcoal (recirculating) filters are replaced, not washed, per the hood manual. Bathroom fan covers drop down for dusting. Clean fans move more moisture and cooking pollutants out (EPA).

  6. Call an electricianPRO
    For a dead, noisy or burning-smelling fan. See breaker guide.
⚠ When to call a pro: a CO alarm goes off; you smell burning, gas or electrical odors; the furnace short cycles (turns on and off rapidly) or overheats after a filter change; ice on the A/C coil; or you want a higher-MERV filter and aren’t sure your system can handle it (EPA suggests asking an HVAC technician). Have a pro tune up the system each year (EPA). Renting? See what you can fix vs. call your landlord.
