In the Home
Mattress, toothbrush, sunscreen — the quiet things with an expiry date.
Many everyday household items last longer than you think — others need replacing on a schedule even when they still look fine. Here is how long a toothbrush, mattress or bottle of sunscreen really lasts, how to spot the end, and how the right care buys you more time.
Quick overview
| Item | Shelf life | Status |
|---|---|---|
| Mattress | 7–10 years | check soon |
| Dishwasher | ~10 years | check soon |
| Laptop | 4–6 years | check soon |
| Phone Battery | 2–3 years | check soon |
| Sunscreen | 3 years | check soon |
| Towels | 3–4 uses | check soon |
Good to know
Many household items age invisibly: a mattress or a sponge looks normal for a long time while moisture, microbes and material fatigue have quietly built up. Others carry a period-after-opening symbol — the open-jar icon with a number like 12M means the contents stay at their best for twelve months after opening. A quick check of texture, smell and performance often tells you more than the purchase date.
For bigger purchases like a dishwasher, laptop or phone, it is worth thinking repair rather than replace. A battery swap, a new SSD or a descale often add years of life — saving money and resources, since manufacturing accounts for most of the environmental footprint. Good care is the most effective lever here.
Care over replacement: what really buys time
For many household items, care decides years of life. A mattress lasts longer if you rotate and flip it regularly and air it out each morning; a pillow gains from a washable cover. Appliances reward a descale and clean filters with a markedly longer life — a dishwasher, kettle and coffee maker otherwise age mostly from limescale. And a phone battery lasts better kept roughly between 20 and 80 percent rather than constantly charged to full.
When replacement really is due, a sober look at the numbers helps: if the repair costs less than half a new one and the device is under about eight years old, repair almost always pays — greener and cheaper. Spare parts and guides are widely available now, and a battery or SSD swap is often done in half an hour.
