A House Beautiful report identifies 14 household items that may need regular replacement, including smoke and carbon monoxide alarms, HVAC filters, towels and bedding. Its suggested timelines are general guidance: check manufacturers’ instructions and replace items sooner if they are damaged, worn or no longer work properly.
House Beautiful has published a list of 14 everyday household items that experts say need regular inspection, cleaning or replacement, including smoke and carbon monoxide alarms, HVAC filters, towels, bedding and grout. The recommendations matter for household safety and upkeep, but the suggested intervals vary by product, manufacturer and use.
The report gives broad replacement ranges for several items. It says smoke and carbon monoxide alarms generally need replacement after five to 10 years, while their exact service life depends on the manufacturer. It recommends monthly alarm testing and annual battery replacement. HVAC filters should be checked monthly and are typically replaced every three to six months, with dirtier filters potentially requiring more frequent changes.
For the bedroom and bathroom, the report suggests replacing shower liners after six months to a year, bath towels after one to three years, mattresses after seven to 10 years, and pillows after one to two years. It gives a two-to-three-year range for sheets and five to 10 years for duvets. The article also recommends replacing or redoing deteriorated grout, typically within five to 10 years, and says visible separation or damage can be a reason to act sooner.
The report names six additional items: kitchen sponges, toilet brushes, showerheads, water filters, cutting boards and fire extinguishers. Replacement needs depend on wear, cleaning and product instructions; the source material does not provide specific intervals for these items. Across the list, signs such as a sagging mattress, misshapen pillow, musty towel or failing alarm are more useful than relying on age alone.
Safety and Wear at Home
Some items in the list affect more than appearance or comfort. A smoke or carbon monoxide alarm that no longer detects hazards reliably may fail to provide timely warning, while damaged grout can let water reach surrounding materials and contribute to damage. A clogged or heavily soiled HVAC filter can also impede system performance, according to the report’s maintenance guidance.
Other recommendations concern cleanliness and everyday use. Towels, pillows and bedding collect moisture, skin debris and other residue over time, while shower liners can develop mold or mildew in damp conditions. The practical takeaway is to inspect regularly, follow care instructions and replace items when they no longer function or clean adequately, rather than treating every suggested lifespan as a fixed deadline.

How the Timelines Were Set
The guidance comes from a House Beautiful report that cites designers and home-maintenance advice. Designer Linda Hayslett recommends washing shower liners every three months and says towels may become scratchy or musty despite washing. Rebekah Zaveloff advises regrouting when grout has pulled away or deteriorated. The report also cites HVAC filter guidance from Energy Star to check filters monthly and replace them about every three months, with more frequent changes if they look especially dirty.
The article references a 2024 SafeHome.org study that found shower curtains had the most germs among the bathroom surfaces examined, including toilet seats. The supplied material does not include the study’s methods or sample size, so that finding should be understood as a result attributed to that study, not a universal measurement. The report also quotes designer Rebecca Bobroff on duvets losing fluffiness and insulating ability through use and washing.
“Even the most gorgeous spaces lose their charm if we forget to update essentials.”

Why Replacement Dates Vary
The listed lifespans are general ranges, not guarantees. The report says alarm replacement timing varies by manufacturer, and the useful life of pillows, linens and other products depends on material, care and how often they are used. It does not provide a specific interval for all 14 items in the supplied source material.
The report also does not establish that every item becomes unsafe at the end of its suggested range. For alarms, consumers should consult the model’s instructions; for other products, the condition of the item and care guidance matter. The source does not provide details about the methods behind the cited shower-curtain study.
A Practical Home Inspection
Readers can use the list as a prompt to check alarms, filters, grout and frequently used linens, then compare each item with its manufacturer’s care and replacement instructions. Test alarms monthly, change their batteries annually as the report advises, and inspect HVAC filters every month. Replace items sooner if they are damaged, no longer perform properly or remain dirty or musty after cleaning.
The source does not announce a new regulation or a follow-up study. Its immediate recommendation is routine household maintenance; the next step for each reader is to check the age and condition of the items in their own home and confirm product-specific guidance.
Key Questions
How often should smoke and carbon monoxide alarms be replaced?
The report gives a five-to-10-year range, but says the exact timing varies by manufacturer. Check the model’s instructions, test alarms monthly and replace batteries annually, according to the report.
How often should HVAC filters be changed?
The report recommends checking filters monthly and replacing them about every three months, with a three-to-six-month range. A filter that looks especially dirty may need to be changed sooner.
What signs mean a mattress or pillow should be replaced?
A sagging mattress or a pillow that has lost its shape may be ready for replacement. The report suggests seven to 10 years for mattresses and one to two years for pillows, while noting that condition matters.
Does every item need to be replaced on a fixed schedule?
No. The timeframes are general guidance. Manufacturer instructions, material, use and condition can change when replacement is appropriate; damaged or poorly functioning items may need attention earlier.
