Do You Need a Humidifier? The Setting That Actually Matters

Dry winter air isn't your furnace's fault. It's physics — and the fix most people reach for can quietly damage the house. In this video: why cold air dries a home out, the humidity number printed on the box that's wrong for winter, what too dry and too humid each cost you, and a three-step way to decide whether you actually need a humidifier. ━━━━━━━━━━━━━━━━━━━━ WHAT YOU'LL LEARN • Why winter air is dry — the physics, not a setting • Why "40 to 60%" on the humidifier box is a summer number • The sliding scale that ties your target to how cold it is outside • What too dry costs you: your body, your wood, your heating bill • What too humid costs you: windows, sills, mould, attic frost • Step 1 — measure before you spend anything • Step 2 — the HRV setting that quietly dries out newer homes • Your three options, and which one actually fits your house ━━━━━━━━━━━━━━━━━━━━ FREE CHECKLIST Run this on your own home — the winter humidity table, the target that moves with the outdoor temperature, and what to check before you buy anything: 👉 https://progradehomescience.com/humid...
