The Best Plants for Re-Humidifying Your Dry Indoor Air

Commercial Air Conditioner System / Residential Air Conditioner System / Tips

Many people suffer from the effects of dry indoor air, especially in the winter when the weather is at its harshest and your split air conditioning unit is working hard to warm up the room.

The lack of moisture around the home can cause your skin to dry out, which in turn leads to irritation. Cracked lips, sore eyes, and dry sinus passages are just a few of the negative side effects. However, using indoor plants can help to increase the moisture levels within the home, much like trees and plants fulfil a similar purpose in the outside world and improve your indoor air quality.

Do indoor plants help with dry air?

The short and simple answer is yes, indoor plants can help to combat dry air, but only if you select the right kind of plant.

Nearly all plants provide some level of humidity and moisture to the surrounding air, but some are far more effective than others.

When the indoor air is dry, particularly during the winter months, a plant can act as a straw. It sucks the water up through the soil, passes it through the stem, and stores it in the leaves before evaporating back into the air. This is referred to as transpiration and is the process that benefits us, humans, as it creates moisture in the air around our skin, eyes, and sinus passages.

Plants with larger leaves often provide better humidity effects than those will small surface areas. These larger leaves absorb more light and CO2, as well as evaporating more water into the air.

Of course, each plant has a different humidification and transpiration rate depending on its species and size.
