Just realized my Peace Lily (Spathiphyllum wallisii) has been drooping way less since I moved it away from the AC vent

Just realized my Peace Lily (Spathiphyllum wallisii) has been drooping way less since I moved it away from the AC vent. I kept thinking it needed more water, but apparently the dry air was the real culprit. Now I'm wondering if the rest of my tropical plants are suffering from the same issue and I just haven't noticed? Anyone else struggle with humidity in their space, or am I overthinking this?
