A House Beautiful report outlines suggested replacement intervals for 14 household items, including smoke and carbon monoxide alarms, shower liners, bedding, HVAC filters and grout. The timelines are general guidance drawn from expert comments and cited recommendations; product instructions, condition and use can change when replacement is needed.
A House Beautiful report lists replacement intervals for 14 everyday household items, arguing that worn alarms, filters, bedding and other essentials can affect home safety, cleanliness and upkeep. The guidance includes suggested time ranges, but several intervals depend on the product, its condition and how often it is used.
The report recommends replacing smoke and carbon monoxide detectors every five to 10 years, while checking the manufacturer’s instructions because service life varies by model. It says alarms should be tested monthly and batteries replaced annually. For shower liners, it suggests a six-month-to-one-year replacement range; designer Linda Hayslett recommends washing liners every three months, while noting that material can become brittle.
For items used in bedrooms and bathrooms, the report gives estimated ranges of one to three years for bath towels, seven to 10 years for mattresses, one to two years for bed pillows, two to three years for sheets, and five to 10 years for duvets. It advises watching for practical signs such as towels that remain musty or feel scratchy, and mattresses or pillows that sag or lose their shape. Proper drying, washing and protective covers may extend the useful life of some items.
The remaining recommendations cover grout, HVAC filters and other household essentials. Grout may need redoing after five to 10 years, but deterioration matters more than the calendar: designer Rebekah Zaveloff says gaps or crumbling grout can allow water to damage drywall. The report recommends checking HVAC filters monthly and replacing them about every three months; it also lists a three-to-six-month range. Its full list includes 14 items, but the supplied source excerpt ends during the HVAC-filter section, so the remaining entries and their specific guidance are not available here.
Safety, Air Quality and Water Damage
The list matters because some household wear is more than an appearance issue. An aging smoke or carbon monoxide alarm may not detect danger as intended, while damaged grout can let water reach surrounding materials. Dirty HVAC filters can affect system operation and contribute to dust and allergens circulating indoors, according to the cited recommendations.
Other items, including towels and bedding, are mainly subject to hygiene, comfort and condition concerns. The report’s intervals are best read as prompts to inspect and maintain household goods—not as proof that every item becomes unsafe or unusable on a fixed date. Visible wear and manufacturer guidance are relevant alongside age.

How the Suggested Timelines Work
The report draws on comments from interior designers and home experts, as well as recommendations it attributes to Energy Star and a 2024 SafeHome.org study. Those sources do not make every timeline universal. Materials, household conditions, maintenance and frequency of use can affect how quickly an item wears out.
For example, the report says pillow lifespan depends partly on fill material, and mattress advice differs for one-sided designs that cannot be flipped. It also notes that people with allergies or asthma may want to wash pillowcases more often: Quince home merchandising head Danielle Hurhula recommends weekly washing at minimum and twice-weekly washing for some people. These are attributed recommendations, not a single standard that applies to every household.
“Even the most gorgeous spaces lose their charm if we forget to update essentials.”

What the Timelines Cannot Settle
The source gives broad replacement ranges, not a product-by-product inspection standard. It does not identify the exact models or manufacturers behind the alarm guidance, and it says detector lifespans vary. Readers should consult the manufacturer’s instructions for their own alarms and other products. The supplied excerpt also stops partway through the HVAC-filter discussion, leaving several of the promised 14 items unspecified.
The report cites a 2024 SafeHome.org study as finding that shower curtains had more germs than other bathroom surfaces, including toilet seats, but the supplied material does not include the study’s methods, sample or measurements. The finding should be understood as a claim attributed to that study, not a universal result for every bathroom. No individual home inspection or testing is presented.
Check Labels and Inspect Wear
Readers can use the guidance as a starting point: check alarm manufacture dates and instructions, test alarms monthly, inspect grout and filters, and look for changes in towels, pillows and mattresses. Replace or repair items based on their condition as well as their age, and follow the care instructions supplied by manufacturers.
The source provides no announced follow-up, deadline or new policy. Any further detail about the other items in the 14-item list would require the full report; the available excerpt does not establish their recommendations.
Key Questions
How often should smoke and carbon monoxide detectors be replaced?
The report gives a general range of five to 10 years, 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 also listed. A filter that looks especially dirty may need more frequent replacement; follow the system and filter instructions.
What are signs that a towel or pillow should be replaced?
The report says towels that remain musty, scratchy or discolored may be due for replacement. A pillow that has lost its shape is another sign. Its suggested ranges are one to three years for towels and one to two years for pillows, depending on use and material.
Does grout need to be redone exactly every five to 10 years?
No. That is the report’s estimated interval, not a fixed requirement. Designer Rebekah Zaveloff recommends looking for grout that has pulled away or deteriorated, which can allow water damage.
