You should probably go clean your filters

Clean air and clean water are crucial to your health. There is maybe nothing on earth less sexy than an air filter — except for, maybe, a water filter. They sit there nestled in our appliances, collecting scuzz and dirt and “impurities,” and we (I) only really think about them when they’re so gross they can’t do their jobs anymore. That’s no way to live, argues senior reporter Allie Volpe; in her latest piece for [Even Better](, Vox’s section for service journalism, she [makes the case for checking your filters](, like, right now, and for getting on a regular schedule when it comes to cleaning and swapping them out. It might feel like a small thing, but it’s a guaranteed way to make your home a little bit cleaner, your life a little bit healthier, and — perhaps most crucially — yourself a little bit smugger. —[Alanna Okun]( senior editor   It's probably time to clean your filters [illustration of person vaccumming home]( Denis Novikov/Getty Images John Ogden-McKee, a self-described “extremely clean person,” has a penchant for filtration. In his home in Dallas, Ogden-McKee, 39, uses five air purifiers with built-in HEPA (short for high-efficiency particulate air) filters — one in every room but the kitchen — drinks water from a filtered container, and fills his drinking glasses with cubes created in an ice maker with a filtration component. He replaces the MERV 13 filter in the air conditioner on the first of every month; as soon as the “change filter” light on the other devices illuminates, he swaps out the used filter for a new one. “We just always have extra,” he says of his stash of assorted filters, which he keeps stored in a closet. “I can’t stand any chaos.” Recently, Ogden-McKee discovered a crack in his highly filtered facade. While cleaning the water fountain for his kittens, Push Pin and Paperclip, Ogden-McKee accidentally discovered the device had a filter — one with four months’ worth of cat water grime. “It was almost like this horror that was in my house that I had no idea about,” Ogden-McKee says. Over the course of a day, you’re likely to encounter any number of filters: furnace/air conditioning filters (they’re the same filter if your home has central AC), vacuum filters, water filters, car cabin air filters, humidifier filters, dishwasher filters, cat fountain filters. The pandemic helped raise the status of air filters as public health officials touted the benefits of ventilation and air purifiers in clearing SARS-CoV-2 in the air.

A filter is a temporary solution.” [Read the full story »]( [Learn more about RevenueStripe...](   TikTok is great for spreading political messages — and conspiracy theories Democrats are trying to win TikTok with facts and nuance.
