So, how often? Let me give you the short, non-corporate answer. If you live a normal life: replace it every 5 to 7 years. If you have kids, pets, or a party habit: every 3 to 4 years.
But really, the best test is the "your gut" test. Walk into your living room barefoot. Does it feel soft and clean? Or does it feel like you’re walking on a flattened, dusty squirrel? If it’s the latter, it’s time.
Don’t be like Sarah. Don’t wait until the path to your couch becomes a geological feature. Your feet—and your guests—will thank you. And your vacuum cleaner might finally get a break.
