A House Beautiful report gathers expert recommendations for when to replace or renew 14 common household items. The suggested timelines vary by product and condition; alarms should follow manufacturer guidance, while filters, linens and other items need regular checks and care.
House Beautiful has published expert guidance on when to replace or renew 14 everyday household items, including smoke and carbon monoxide alarms, mattresses, towels and HVAC filters. The report offers estimated timelines and signs of wear, but says replacement schedules can depend on the product, its condition and manufacturer instructions.
The recommendations range from checking smoke and carbon monoxide alarms every month and replacing their batteries annually to replacing the units after five to 10 years. The report says alarm life spans vary by manufacturer, so owners should check the model’s instructions rather than rely on a single universal date. It warns that aging detectors may become less sensitive.
For items exposed to moisture or frequent use, the report suggests replacing shower liners every six months to one year and bath towels every one to three years. Towels may need replacing sooner if they remain musty after washing, feel scratchy or show discoloration. Designer Linda Hayslett recommends washing shower liners every three months and says excess detergent can build up in towel fibers.
Other estimates include redoing deteriorated grout every five to 10 years, replacing mattresses after seven to 10 years and pillows after one to two years. The report recommends replacing sheets after two to three years and duvets after five to 10 years. It also cites Energy Star among sources advising homeowners to check HVAC filters monthly and replace them about every three months; the supplied report excerpt says to replace them sooner if they look especially dirty.
Wear Can Affect Safety and Comfort
These items serve different purposes, but neglect can carry consequences beyond appearance. A detector that does not work properly may fail to warn occupants during an emergency, while deteriorated grout can allow water to reach surrounding materials. Dirty HVAC filters can restrict system performance and allow dust and allergens to circulate, according to the report’s cited guidance.
For bedding, towels and shower liners, the main concerns described are loss of function, accumulated grime and persistent moisture. The suggested ages are reference points, not guarantees: visible damage, odor, reduced support or poor performance may be reasons to act earlier. Regular checks can help households spot problems before an item reaches its estimated replacement age.

Timelines Depend on the Item
The report draws on comments from designers and home-care guidance, rather than presenting a new scientific study of all 14 products. It includes advice from Linda Hayslett of LH.Designs, Rebekah Zaveloff of Imparfait Design Studio, Vyanca Soto of Market Studio Interiors, Rebecca Bobroff of Rebecca Bobroff Design and Danielle Hurhula of Quince.
Some recommendations focus on care that may extend an item’s useful life. Hayslett advises flipping mattresses every six months when they are designed to be flipped; the report also recommends mattress protectors and regular vacuuming. Soto says towels should dry fully between uses. Hurhula recommends washing pillowcases at least weekly, and twice weekly for people with allergies or asthma, among other circumstances.
The supplied article excerpt lists only part of its 14-item guide: it gives details for alarms, shower liners, towels, grout, mattresses, pillows, bed linens and HVAC filters, but does not provide the remaining six items. No publication date is included in the supplied material.

No Single Schedule Fits Every Home
The recommended time frames are general estimates, and the source does not provide product-by-product testing or a single standard that applies to every household. Actual lifespan can depend on manufacturer guidance, material, use, washing and moisture. The supplied excerpt also ends during its HVAC-filter discussion and does not identify the other six items in the 14-item headline.
The report cites a 2024 SafeHome.org study that found shower curtains had the most germs among the bathroom surfaces it examined, but the supplied material does not give the study’s methods or data. That result should not be read as proof that every shower liner is unsafe at a particular age. The source also does not establish a universal health risk from older towels, bedding or pillows.
Check Labels and Signs of Wear
Homeowners can use the advice as a prompt to inspect items, but should check product labels and manufacturer instructions—especially for smoke and carbon monoxide alarms. Test alarms monthly and replace batteries annually, as the report advises, while confirming the unit’s replacement schedule for its specific model.
For other items, look for the problems named in the report: grout pulling away, mattresses sagging, pillows losing shape, towels staying musty and HVAC filters appearing heavily soiled. The source does not describe a formal follow-up or regulatory change; the next step is routine household inspection and replacement or repair when an item’s condition warrants it.
Key Questions
How often should smoke and carbon monoxide alarms be replaced?
The report gives a general range of five to 10 years, but says the correct schedule varies by manufacturer. Check the instructions for the specific model. It also recommends testing alarms monthly and replacing batteries yearly.
How often should HVAC filters be changed?
The report cites guidance to check filters monthly and replace them about every three months. It says a filter that looks especially dirty may need to be changed sooner; follow the filter and HVAC manufacturer’s directions.
What are signs that towels need replacing?
The report suggests replacing towels after roughly one to three years, or sooner if they remain musty after washing, feel scratchy or become discolored. Letting towels dry properly between uses may help limit mildew.
How long do mattresses and pillows typically last?
The report suggests replacing mattresses after seven to 10 years and pillows after one to two years. A sagging mattress or a pillow that has lost its shape may need attention sooner than those estimates.
