The ideal indoor humidity level is generally between 30% and 50%. This range helps ensure comfort, reduces the risk of mold and mildew, prevents condensation on windows, and protects your home and belongings from moisture damage.

• 30%-40%: This range is often recommended in colder weather to prevent condensation and ice buildup on windows.
• 40%-50%: This range is usually preferred in warmer weather to maintain comfort and avoid dry air.

In colder months, you might want to keep the humidity on the lower end of that range to avoid condensation on windows, while in warmer months, you might aim for the higher end to counteract the dry air from air conditioning. Using a hygrometer to monitor indoor humidity can help you keep it in the optimal range.
