If you haven't changed your HVAC filter in more than three months, we're not gonna scold you. That would make us hypocrites.😬 See, even we sometimes neglect the air filter that removes dirt, dust, allergens and other impurities from the indoor air in our homes. And that's despite our constant reminders to you to change your furnace filter, or the return filter in your wall or ceiling, on a quarterly basis. But that DOESN’T make it right! Watch as ‎@Matt Schmitz takes his lumps while also demonstrating exactly why air-filter attententiveness is important... #hvac #hvacfilter #homeowner #homemaintenance #fyp
