Houseplants that Increase Humidity

A collage of Houseplants that Increase Humidity.

Houseplants, through photosynthesis, generate oxygen simply by their presence while removing harmful or toxic chemicals from the air within a room.

Certain houseplants help restore moisture into the air for homes that lack humidity and are dry – which is often the cause of health issues. An ideal humidity helps avoid medical conditions like respiratory problems, dry skin, and sore throats.

Plants generate moisture through what scientists term transpiration. A plant releases water vapor similarly to the way an athlete releases water vapor when sweating. The leaves of the houseplant contain small pore-like edifices – known as stomata. These apertures release water vapor into the air, which then increases the humidity.

Here are some great houseplant options to increase humidityinany room in your home.

The Areca Palm is a tropical splash for any indoor room with feathery fronds that may have up to 100 leaflets.

The Areca Palm, which is sometimes called the Butterfly Palm, needs just the right amount of light, which is bright but indirect. The best location is facing a western or southern window. This attention-grabbing houseplant is not challenging to maintain but will not tolerate a neglectful plant owner. In the summer and spring, the Areca Palm should be watered often enough so that there is moist soil. In the colder seasons, the soil should be kept slightly dry between each plant watering.

This palm variety is noted to have a transpiration rate of 10, giving off about one quart of water vapor every day. The Areca Palm is certified by NASA to remove pollutants – like xylene, toluene, and formaldehyde from the air.

2. Peace Lily (Spathiphyllum)

The Peace Lily is a gorgeous perennial that has dramatic white flowers.

The Peace Lily is a popular plant found in homes and offices due to their ease of care. This type of plant can brighten a room and cleanse the air. The Peace Lily does well with medium to low-lit locations and often thrives in partial shade. These plants like to be watered a lot, and they prefer that it be at once, with time to dry out. Make sure the Peace Lily’s drainage is good to avoid root rot.

The Peace Lilly is noted to have a transpiration rate of 8 and is well-known for its ability to cleanse the air and the neutralization of toxins like carbon monoxide. The Peace Lily should be kept out of reach from pets because accidental ingestion can be toxic.

3. Dwarf or Pygmy Date Palm (Phoenix roebelenii)

6. Jade Plant (Crassula ovata)

Jade Plant on a pot with white stone.

The Jade Plant is a long-living succulent house plant that many people consider symbolic of good luck.

The Jade Plant, which is a common succulent house plant, loves the sun (and needs four or more hours daily) and needs full of growing appropriately. They are easy to grow, although they grow slowly. Too little sun and their growth are stunted. As a succulent, the Jade Plant prefers the right amount of water which means do not let the Jade Plant’s soil dry out and do not overwater. It is best to water the beautiful Jad Plant when the top of the soil is dry to the touch. If the Jade loses leaves, it is likely due to underwatering.

The Jade Plant is noted to have a transpiration rate of 5. Studies have shown that the Jade Plant can increase humidity up to 30%, with the ability, as a CAM-type of plant, to do so even in the dark.

7. Arrowhead Plant/Vine or Goosefoot (Syngonium podophyllum)

Large leaves of Arrowhead Plant.

The adaptable Arrowhead Plant can be trained to grow in any direction.

The Arrowhead is an easy-care houseplant that helps add moisture back to a room. They are available in many varieties, each with a unique look and personality. The Arrowhead Plant is perfect for individuals who have no experience caring for houseplants. They do well in low light and will likely grow in any room but grow faster if given indirect light and even artificial light. As the plant matures, tie older vines to allow new growth to come forth. It is essential to let the Arrowhead Plant’s soil dry a bit before re-watering the Arrowhead Plant.

The Arrowhead Plant has a transpiration rate of 7, which makes it an effective regulator of room humidity. Note that the Arrowhead Plant is poisonous and should be kept out of reach by small children and pets.

8. Prayer Plant (Maranta leuconeura ‘Kerchoveana’)

The Golden Pathos is among the hardiest of house plants that generate additional moisture in the air.

The Golden Pathos, which is also known as Devil’s Ivy (because it so easily evades death), is not the flashiest, although it is pretty if hung along a shelf. It is quite versatile because it loves bright and indirect light but is low-light tolerant. This plant gives a sign when it is time to water the Golden Pathos – its leaves begin to droop a bit. Generally, it is good to allow the soil to be dry in-between each watering.

The Golden Pathos is noted to have a transpiration rate of 7 and is toxic to cats and dogs, so keep it high and out of reach for four-legged family members. Even NASA has shown plant increases humidity.

10. Ferns (Nephrolepis exaltata)

Luscious green leaves of Ferns.

Ferns offer year-round lush fronds but like to be pampered.

Ferns are native to woodlands and forests, which makes their roots delicate due to the light texture of forest soil. Ferns prefer morning or late afternoon sun but do not light strong sunlight. The fern will do well in low light but needs breaks in brighter locations. The compost or soil for the fern cannot be overwatered or water-logged as this may lead to decay at the root level. It is usually best to water the fern with a small amount of water daily.

This fern variety is noted to have a transpiration rate of 9, which is among the highest on the scale. Ferns offer added humidity when needed. Ferns also help to remove unhealthy toxins in the air.

11. Bamboo Palm (Chamaedorea sifrizii)

The Bamboo Palm brings warmth while increasing the humidity in a room that tends to be dry.

These palm trees grow up to 12 feet when mature and span as wide as five feet. Unlike most palms, the Bamboo Palm grows well in low-lit environments, although a sunnier location will likely cause the Bamboo Palm to grow to its maximum height. This palm variety prefers room temperature water that has been filtered when the soil is dry to the touch. It is important not to over-water or leave pooled water, so check the drainage regularly.

The Bamboo Palm is noted to have a high transpiration rate of 9. This palm helps to filer air toxins like benzene and formaldehyde. For added humidity, place the plant within a saucer that has pebbles and some water.

12. Anthurium (Anthurium)

The Parlor Palm is a true tropical palm that thrives well indoors.

The Parlor Palm, which is also known as the Neanthe Bella Parlor Palm, is a hardy, slow-growing plant that can grow up to six feet indoors and twice that outside. This palm is native to Central America and often used in flower arrangements and wreaths because they survive more than 30 days after being cut. Like most palms, the Parlor Palm prefers indirect and bright light but is adaptive to lower light areas. The soil, when planted indoors, should be a peaty soil mix that drains well. Be careful of over-watering this palm houseplant.

The Parlor Palm is noted to have a transpiration rate of 7. It is well-known for its air-purifying abilities and a high transpiration rate which can help regulate the humidity of an indoor room.

15. Dwarf Umbrella Tree (Schefflera)

Dwarf Umbrella Tree with water droplets.

The Dwarf Umbrella Tree is a multiple trunk plant that grows as high as 15 feet outdoors.

The Dwarf Umbrella Tree often needs pruning because it is a fast-growing species with a remarkable ability to add moisture to the air. When grown indoors, the Dwarf Umbrella Tree likes bright light that is not direct. If placed in a low-lit area, it will simply grow more slowly. It is essential not to overwater the Dwarf Umbrella Tree, which usually results in the stems and the leaves turning brown. When the top soil dries out, water this houseplant with room temperature water.

The Dwarf Umbrella Tree has a transpiration rate of 7. In addition to releasing water vapor to room air, the Dwarf Umbrella Tree is also great at eliminating toxins – even chemicals released by cigarette smoke. This tree is considered mildly toxic to household pets.

16. Philodendron (Philodendron)
