Household
Home upkeep: filters, sheets and appliances
Air purifier and air conditioner filters, dehumidifiers, water filter cartridges, bedding, the fridge and the washing machine — how often, and how to tell when it’s time.
How often should you change an air purifier filter?
Main HEPA and carbon filters last from about 6 months to 2 years depending on the model, so follow the filter light. Keep the pre-filter clean in between.
How often should you clean an air conditioner filter?
Clean a split (ductless) AC filter about every two weeks in heavy use and check central air filters monthly. How to wash it, dry it, and avoid common mistakes.
How often should you wash your sheets and pillowcases?
Wash sheets and pillowcases weekly, every two weeks at most. Plus duvets, comforters and pillows, the water temperature for dust mites, and when to replace.
How often should you change a water filter cartridge?
Change a water filter by its gallon or month rating, whichever comes first: about every 4 weeks to 2 months for jugs, and 6–12 months for RO system stages.
How often should you clean a dehumidifier filter?
Clean a dehumidifier filter about every two weeks, or every 250 hours of running, and wash the bucket every few weeks to stop mold. Step-by-step care for both.
How often should you clean a washing machine?
Run a tub-clean cycle about once a month or when the reminder light comes on. Plus front-load vs. top-load care, the door seal, drain filter and musty smells.
How often should you clean your fridge?
Wipe spills right away, clear out old food weekly and deep clean about once a month. Plus the right fridge temperature, what to clean with, odors and leftovers.
