When you’re living, cooking, and sleeping all in more or less the same space—which is the case with many tiny homes—you may be unwittingly breathing in air that’s significantly less than fresh. In small spaces, pollutants can build up quickly. And tiny homes are often DIY builds so escape any building code inspections that would flag dangerous air quality.
Another problem you might face with the air in your tiny home? It’s damp. If your tiny home was built without adequate ventilation, you might experience high levels of humidity, with issues such as condensation, mold or mildew, or an increase in allergies.
The coolest tiny house furniture or niftiest tiny house appliances aren’t much good if you can’t enjoy your tiny home because of poor air quality. Luckily, it’s easy to resolve both of these issues. All you need is either an air purifier, a dehumidifier, or both.
Air purifier vs. dehumidifier: what’s the difference?
First up, what’s the difference between an air purifier and a dehumidifier?
An air purifier is essentially designed to cleanse and purify the air in your home, removing impurities such as smoke, dust, and odors—useful if your tiny home has poor ventilation. They function by way of filters and fans, capturing pollutants and particles and pushing clean air back out into your home.
A dehumidifier is designed to remove moisture from the air. If your windows frequently have condensation on them or you notice a musty odor or stickiness in your tiny home—or any watermarks on the walls—you may need to get yourself a dehumidifier. You can check the humidity levels in your tiny home are safe using a hygrometer.
