Humidifiers
We are not telling you to throw your humidifier in the trash, far from it, it adds moisture to the air to prevent dryness that can cause irritation in many parts of the body. What we do recommend is keeping it below 50% humidity.
And there is a very good reason for that, anything higher than 50% and you will create an environment that will encourage mold formation, not only that, you’ll make the dust mites very happy! As mold and dust mites are massive sources of indoor allergens, your respiratory system will thank you for not touching that dial.
