A House Beautiful report outlines suggested replacement intervals for 14 everyday household items, including smoke and carbon monoxide alarms, shower liners, towels, mattresses and HVAC filters. The timelines are general guidance: product instructions, condition and use can change when an item needs attention.
House Beautiful has published a guide to 14 household items that may need replacement or repair more often than owners expect, with suggested timelines ranging from months to a decade. The list covers safety devices, bedding, bathroom items and HVAC filters, and points readers to product condition and manufacturer guidance rather than treating every interval as a fixed rule.
For smoke and carbon monoxide alarms, the report gives a general replacement range of five to 10 years, while stressing that the model’s manufacturer determines its lifespan. It also says to test alarms monthly and replace their batteries annually. Shower liners are listed at six months to one year; designer Linda Hayslett recommends washing them every three months, while mold, mildew or brittle material can signal a need for earlier replacement.
The suggested intervals for textiles vary: bath towels, one to three years; bed pillows, one to two years; sheets, two to three years; and duvets, five to 10 years. The report says to judge towels by absorbency, texture, persistent musty smells or discoloration, and pillows by whether they have lost their shape. It recommends washing pillowcases at least weekly, with more frequent washing for some people, including those with allergies or asthma.
The list also includes mattresses, seven to 10 years; grout, five to 10 years; and HVAC filters, three to six months. A sagging mattress, separated or deteriorating grout, and a visibly dirty filter are signs to check sooner. The source excerpt ends partway through its HVAC discussion and does not provide the other items or the full list of 14, so those entries cannot be reported here.
Small Upkeep, Safety and Indoor Air
Some of the suggested changes concern comfort and cleanliness, but others can affect home safety and maintenance. The report warns that aging alarms may lose sensitivity, potentially delaying detection in an emergency. It also says damaged grout can allow water to reach drywall, creating a risk of water damage.
HVAC filters are another practical concern: the report cites Energy Star and maintenance experts recommending regular checks and replacement to help the system operate properly and limit dust and allergens. The guidance gives homeowners a reason to inspect items they may overlook, while emphasizing that condition and manufacturer instructions matter alongside calendar-based estimates.

Intervals Depend on Use and Condition
The article’s guidance draws on comments from home designers and household-maintenance recommendations. Its timelines are not presented as universal product standards. Alarm lifespans vary by manufacturer, while the condition of towels, pillows, grout and filters can depend on use, care and the environment.
For example, the report advises allowing towels to dry fully between uses and avoiding excess detergent, which can build up in fibers. It also recommends checking HVAC filters monthly and replacing them more often if they appear especially dirty. For mattresses, it suggests rotating or flipping them every six months when the design permits, and using a protector to help keep them clean.
“Even the most gorgeous spaces lose their charm if we forget to update essentials.”
— Linda Hayslett, principal designer at LH.Designs
Which Timelines Fit Each Home
The report’s intervals are general recommendations, not guarantees that every item must be replaced on a specific date. Exact alarm replacement schedules depend on the manufacturer and model, and the source does not identify a single standard that applies to all products. Household conditions, cleaning habits and visible wear can also affect the timing.
The supplied source excerpt lists only eight of the promised 14 items and cuts off during its HVAC-filter section. It does not provide the remaining six recommendations or the full supporting discussion. The report also cites a 2024 SafeHome.org study saying shower curtains had the most germs among bathroom surfaces, but the excerpt gives no study methodology or detailed comparison figures.
Check Labels and Inspect Items
Homeowners can start by checking alarm labels or manufacturer instructions, testing alarms monthly and inspecting filters, grout and frequently used textiles for signs of wear. Replace or repair items sooner when they show damage, no longer work properly or remain dirty or musty despite appropriate care.
The source material provides no follow-up announcement or schedule for additional reporting. For the six items absent from the supplied excerpt, readers would need the complete House Beautiful article before relying on its full 14-item list.
Key Questions
How often should smoke and carbon monoxide alarms be replaced?
The report gives a five-to-10-year range, but says the correct timing depends on the manufacturer and model. Test alarms monthly and replace batteries annually, following the product instructions.
When should towels be replaced?
The report suggests one to three years. Scratchiness, reduced absorbency, persistent musty smells or discoloration can indicate that towels need replacing sooner.
How frequently should HVAC filters be changed?
The guide lists three to six months and recommends checking filters monthly. A filter that looks especially dirty may need more frequent replacement; follow the equipment maker’s guidance.
Are the replacement intervals strict rules?
No. They are general recommendations. Product instructions, visible condition, usage and household conditions can affect when replacement or repair is appropriate.
