A House Beautiful report recommends checking the condition and age of 14 everyday household items, including smoke and carbon monoxide alarms, shower liners, bedding and HVAC filters. Its timelines are general guidance; manufacturer instructions, visible wear and household conditions can change when an item needs attention.
House Beautiful has published expert guidance on when to replace 14 common household items, including smoke and carbon monoxide alarms, towels, mattresses, bedding and HVAC filters. The recommendations matter because worn or poorly maintained items may affect home safety, cleanliness and appliance performance, but the suggested timelines are not universal and should be checked against product instructions and actual condition.
The report gives a general replacement range of five to 10 years for smoke and carbon monoxide detectors, while advising readers to check the manufacturer’s instructions for their specific model. It also recommends testing alarms monthly and replacing batteries annually. For shower liners, it suggests a range of six months to one year; designer Linda Hayslett recommends washing liners every three months, while noting that damp conditions can encourage mold and mildew.
For textiles, the report suggests replacing bath towels after one to three years, bed pillows after one to two years, sheets after two to three years, and duvets after five to 10 years. It says wear and condition matter: towels that stay musty or feel scratchy, and pillows that lose their shape, are signs to consider replacement. Designer Rebecca Bobroff says duvets can lose fluffiness and insulating ability with regular use and washing. The report also cites a recommendation from Quince home merchandising head Danielle Hurhula to wash pillowcases at least weekly, or twice weekly for some people with allergies, asthma or sensitive skin.
Other items on the list include mattresses, grout and HVAC filters. The report gives mattresses a seven-to-10-year range, with sagging as a clear warning sign, and says filters should be checked monthly and replaced about every three months, with more frequent changes potentially needed if they look dirty. It recommends inspecting grout and redoing deteriorated sections; the suggested five-to-10-year interval is a broad guide, not a substitute for checking for gaps or water damage.
Safety, Hygiene and Home Maintenance
Some replacements are mainly about comfort or appearance; others can affect a home’s safety and upkeep. An aging alarm may not detect smoke or carbon monoxide as intended, while deteriorated grout can allow water to reach surrounding materials. The report quotes Imparfait Design Studio cofounder Rebekah Zaveloff warning that failing grout can lead to water damage to drywall.
Routine checks may also help homeowners spot changing conditions before they become more costly. A clogged or dirty HVAC filter can affect system operation, while neglected bedding and damp shower liners can accumulate grime or develop odors. The report’s dates offer a reminder to inspect these items, but they do not establish that every product becomes unsafe or unusable at a specific age.

Replacement Timelines Are General Guides
The article is a practical home-maintenance report based on comments from designers and other home experts, rather than a new government rule or product-safety notice. Its advice spans replacement, cleaning and inspection: for example, washing a liner can help maintain it, but does not prevent eventual material wear.
Several recommendations depend on product construction and use. The report says alarm replacement timing varies by manufacturer, and pillow life depends partly on fill material. Household factors such as dampness, pets, allergies, washing frequency and visible deterioration can also affect how quickly items need attention. Readers should use manufacturer guidance and condition checks alongside the broad ranges.
“Even the most gorgeous spaces lose their charm if we forget to update essentials.”

When Each Item Needs Replacing
The source does not provide a universal test for deciding when every item has reached the end of its useful life. Actual lifespan varies with product design, care, household conditions and manufacturer guidance. The report also does not establish that every item within a listed age range presents a health or safety risk.
Its reference to a 2024 SafeHome.org study says shower curtains had the most germs among the bathroom surfaces examined, but the supplied material gives no study methods, sample size or detailed comparison data. That finding should be understood as a reported study result, not proof that every shower liner is more contaminated than every other bathroom surface.
Check Labels and Inspect for Wear
Homeowners can start by checking alarm manufacture dates and model instructions, then testing alarms monthly and replacing batteries on the schedule specified by the manufacturer. The report also recommends checking HVAC filters each month and changing them according to their condition and system guidance. Inspect grout for gaps and look for sagging mattresses, misshapen pillows, persistent towel odors or damaged liners.
For items that remain in service, regular care can help: dry towels between uses, wash bedding routinely and clean shower liners as appropriate for their material. Replacement decisions should follow product instructions and visible condition, rather than relying on a calendar alone.
Key Questions
How often should smoke and carbon monoxide alarms be replaced?
The report gives a broad range of five to 10 years, but says the exact timing varies by manufacturer. Check the instructions for the specific alarm, test it monthly and replace batteries annually as advised in the report.
How often should HVAC filters be changed?
The report recommends checking filters monthly and replacing them about every three months. A visibly dirty filter may need changing sooner; follow the filter and HVAC system instructions.
What are signs that towels or pillows need replacing?
For towels, the report points to scratchiness, persistent musty smells or discoloration. For pillows, loss of shape is a sign to consider replacement. Its suggested ranges are one to three years for towels and one to two years for pillows.
How long do sheets and duvets typically last?
The report suggests replacing sheets after two to three years and duvets after five to 10 years. Wear, washing and household use can affect those timelines.
When should grout be redone?
The report gives a broad five-to-10-year range, but says to inspect for grout that has pulled away or deteriorated. Those signs may warrant repair sooner, particularly because damaged grout can contribute to water damage.
