How Often to Replace Common Household Items

Many household items wear out gradually, so it is easy to keep using them past their useful life. The timelines below are typical guidelines. Your product's manual and manufacturer always come first, and usage affects how long things last.

Safety items

• Smoke alarms: Replace the whole unit about every 10 years, and test monthly. Replace batteries as needed, or when the unit chirps.
• Carbon monoxide alarms: Lifespans vary by model, often between 5 and 10 years. Check the date or label on your unit.
• Fire extinguishers: Check the pressure gauge regularly and follow the label for replacement or servicing.

Air and water

• HVAC filters: Usually every one to three months, depending on the filter type, pets and how often the system runs.
• Refrigerator water filters: Often about every six months. Check your model's instructions.
• Range hood filters: Wash or replace according to the manual, and more often if you cook frequently.

Cleaning tools

• Kitchen sponges: Replace every week or two, or sooner if they smell. Microwaving or running through the dishwasher is not a substitute for replacement.
• Dishcloths and towels: Launder often and retire them when they stay musty or worn.
• Vacuum bags and filters: Follow your model's guidance. Full bags and clogged filters reduce suction.

Bedding and furniture

• Pillows: Many last one to three years, depending on fill and use.
• Mattresses: Commonly seven to ten years, though comfort and condition matter more than a calendar.
• Sagging, lumpy or stained items are signs it is time, whatever the date says.

Big systems

• Water heaters: Often last roughly 8 to 12 years. Rust, leaks and strange noises are warning signs.
• Washing machine hoses: Inspect regularly and replace if they bulge or crack. Many experts suggest replacing them every few years.

A simple system

Write replacement dates on the item with a marker, or keep a list on your phone with repeating reminders. Ten minutes of tracking saves emergencies later.
