Household Items You Need To Replace Sooner Than You Think
1. 牙刷：刷毛磨損後，清潔效果有限，所以每三個月最好更新。
2. 步行鞋：時間久了會失去結構和支撐力，建議每半年換新。
3. 床墊：磨損或下垂的床墊可能會使背部疼痛和僵硬，美國國家睡眠基金會建議，每八年更新一個。
4. 枕頭：用久了會失去支撐力，再加上塵蟎和死皮，雖然定期清洗有幫助，但醫生建議每隔兩年就要換新的。
5. 冰箱濾水器：每六個月需要更換過濾器，以有效地減少飲用水中的污染物。
6. 煙霧警報器和滅火器：隨著時間，煙霧探測器會失去其靈敏度，每隔10年就應更新，廠家通常建議，每隔5至15年更換滅火器，並每月檢查壓力表。
7. 淋浴絲瓜瓤：每三至四個星期就應替換，否則只是越來越多的細菌躲在潮濕的角落和縫隙裏。
8. 廚房海綿：只要它看起來破舊，（兩至八個星期之間），就用新的。
1. Toothbrushes
The bristles become frayed and worn over time, so they won’t clean your teeth as well. Get a new one every three months.
2. Walking Shoes
Your favorite tennies won’t last forever. They lose structure and support as you wear them, so if you walk often, replace them every six months.
3. Mattresses
We know a mattress is a major purchase, but the National Sleep Foundation recommends buying a new one every eight years. Worn or sagging spots could increase back pain and stiffness, and discomfort could also disrupt your shuteye. We’ve said it before, but we’ll say it again: Getting a good night’s sleep is critical to your health and happiness.
4. Pillows
Like your mattress, your pillows deflate and lose their supportive (and comfy) cushion. Plus a 10-ounce pillow can double its weight in three years … because of collecting dust mites and dead skin (mega ick). Regular washing can help, but doctors recommend tossing them every two years.
5. Refrigerator Water Filters
Has your stream of filtered water become a trickle? Filters need to be replaced every six months to effectively minimize contaminants in your drinking water.
6. Smoke Alarms and Fire Extinguishers
Smoke detectors lose their sensitivity over time, so get new ones every 10 years. Manufacturers typically recommend replacing fire extinguishers every five to 15 years, and check the pressure gauge monthly. Rechargeable extinguishers should be serviced every six years.
7. Shower Loofahs
Growing bacteria simply love your fluffy bath sponge’s damp nooks and crannies. Toss it every three to four weeks.
8. Kitchen Sponges
You can sanitize your sponge prolong its life. But as soon as it’s looking messy and worn (between two to eight weeks), start using a new one.
9. Teflon Pans
Guilty of cooking with a chipped non-stick pan? Those flakes and crevices could release toxic compounds, so it’s time for a change. With moderate use, experts say nonstick cookware should last three to five years.
