A House Beautiful report outlines replacement intervals and warning signs for 14 everyday household items, including smoke and carbon monoxide alarms, towels, mattresses and HVAC filters. The suggested timelines are general guidance: product instructions, condition and use can change when an item needs attention.
House Beautiful has published a guide to 14 everyday household items that may need replacement or repair sooner than owners expect, drawing on advice from designers and home-maintenance guidance. The list spans safety alarms, bedding, bathroom items and HVAC filters, with suggested timelines intended as prompts to check product condition and manufacturer instructions—not universal deadlines.
The recommendations include replacing smoke and carbon monoxide alarms every five to 10 years, depending on the manufacturer, while testing them monthly and replacing batteries annually. The report says alarm sensitivity can decline with age, making an outdated or poorly functioning unit a safety concern. Owners should check the model’s instructions for its replacement date and testing requirements.
For frequently used textiles, the guide gives approximate ranges: shower liners every six months to a year, bath towels every one to three years, bed pillows every one to two years, and sheets every two to three years. Duvets may last five to 10 years. The report advises replacing items sooner if they remain musty after washing, lose their shape or absorbency, become discolored, or show other signs of wear. It also recommends washing pillowcases at least weekly, with more frequent washing suggested for some people with allergies, asthma or sensitive skin.
Other items named are grout, mattresses and HVAC filters. The report suggests redoing grout after five to 10 years, or earlier if it pulls away or deteriorates; replacing mattresses after seven to 10 years, particularly if they sag; and changing HVAC filters every three months, while checking them monthly. Filter needs vary: a visibly dirty filter may call for more frequent replacement, and the system’s instructions should guide owners.
Small Checks Can Protect Home Safety
The advice matters because wear is not only cosmetic. A failing smoke or carbon monoxide alarm may not provide timely warning in an emergency, while damaged grout can allow water to reach surrounding materials. Dirty HVAC filters can affect system operation and the amount of dust and allergens circulating indoors, according to the guidance cited in the report.
For textiles, replacement is more often about condition, hygiene and comfort than a fixed safety threshold. Towels that stay musty, pillows that no longer hold their shape and bedding that has deteriorated can be signs that washing and routine care are no longer enough. Checking items periodically can help households prioritize urgent repairs and avoid treating every suggested interval as an automatic replacement date.

How the Timelines Were Framed
The source is a House Beautiful household-maintenance report that asked interior-design professionals about items that can be overlooked in otherwise well-kept homes. Its recommendations combine expert observations with general maintenance advice; the supplied material does not present a single standardized schedule for every product or household.
The report cites Energy Star and HVAC maintenance experts for checking filters monthly and replacing them about every three months. It also refers to a 2024 SafeHome.org study that found shower curtains had the most germs among the bathroom surfaces it examined, including toilet seats. That finding is attributed to the study and does not establish that every shower liner is unsafe or must be replaced on the same schedule.
“Even the most gorgeous spaces lose their charm if we forget to update essentials.”

Replacement Dates Vary by Product
The timelines are general recommendations, not guarantees. The source material does not provide a complete list of all 14 items: the supplied report excerpt ends during its HVAC-filter section, so the remaining entries and any associated advice cannot be verified here. Replacement intervals can also depend on a product’s materials, model, use, care and condition.
The excerpt does not identify the publication date, provide the full methodology for the cited SafeHome.org study, or specify a universal test for deciding when every textile has reached the end of its useful life. For alarms and HVAC equipment, product-specific instructions and applicable safety guidance take precedence over a broad range in a lifestyle report.
Check Labels and Inspect Wear
Households can use the recommendations as a checklist: find alarm manufacture or replacement dates, test alarms monthly, inspect grout for gaps, and check HVAC filters monthly. Before replacing an item, consult its manufacturer’s care and maintenance instructions and assess visible wear, performance and cleaning history.
The report does not announce a new regulation or formal public-health directive. Its practical next step is routine inspection: replace or repair items when their instructions, age or condition indicate they are no longer working as intended.
Key Questions
How often should smoke and carbon monoxide alarms be replaced?
The House Beautiful report gives a broad five-to-10-year range, but says the interval depends on the manufacturer. Check the model’s instructions, test the alarm monthly and replace its batteries annually, as applicable to the unit.
How often should HVAC filters be changed?
The report cites guidance to check filters monthly and replace them about every three months. A filter that looks especially dirty may need earlier replacement; follow the HVAC system and filter manufacturers’ instructions.
Do the listed timelines mean every item must be replaced on schedule?
No. The ranges are general guidance. Materials, frequency of use, care and condition can affect how long an item lasts, so inspect it and consult product-specific instructions.
What are signs that towels or pillows need replacing?
The report points to towels that remain musty after washing, feel scratchy or lose absorbency, as well as pillows that lose their shape. Those condition changes may be more useful than a calendar alone.
