15 Houseplants for Improving Indoor Air Quality

In the late '80s, NASA and the Associated Landscape Contractors of America studied houseplants as a way to purify the air in space facilities.

• They found several plants that filter out common volatile organic compounds . Lucky for us the plants can also help clean indoor air on Earth, which is typically far more polluted than outdoor air. 
• Other studies have since been published in the Journal of American Society of Horticultural Science further proving the science.

      Aloe (Aloe vera)

This easy-to-grow, sun-loving succulent helps clear formaldehyde and benzene, which can be a byproduct of chemical-based cleaners, paints and more. Aloe is a smart choice for a sunny kitchen window. Beyond its air-clearing abilities, the gel inside an aloe plant can help heal cuts and burns.

Aloe Vera Plant [Uses and Benefits]

          Aloe Vera is a species of Aloe, native to northern Africa.Its era has long been a popular houseplant. Often called the 'miracle plant' or the 'natural healer', Aloe Vera is a plant of many surprises. It flourishes in warm and dry climates, and to many people it looks like a cactus with fleshy thorny leaves. In fact it is a member of the Lily family, staying moist where other plants wither and die by closing its pores to prevent moisture loss.

There are around 400 species of Aloe, but it is the Aloe Barbadensis Miller (Aloe Vera or "true aloe") plant which has been of most use to mankind because of the medicinal properties it displays.

     Some species, particularly Aloe vera are used in alternative medicine and in the home first aids. Both the translucent inner pulp and the resinous yellow aloin from wounding the Aloe plant are used externally to relieve skin discomforts. As an herbal medicine, aloe vera juice is commonly used internally to relieve digestive discomfort "aloe for heartburn".

Common houseplants used against indoor air pollution

          Common indoor plants may provide a valuable weapon in the fight against rising levels of indoor air pollution. NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside homes, indoor public spaces and office buildings.

         The indoor pollutants that affect health are formaldehyde, Volatile Organic Compounds (benzene and trichloroethylene or TCE), airborne biological pollutants, carbon monoxide and nitrogen oxides, pesticides and disinfectants (phenols), and radon. These pollutants contribute to ’sick building sindrome’, which causes symptoms ranging from allergies; headaches and fatigue through to 

nervous-system disorders;

cancer and death.

Top ten plants for removing formaldehyde, benzene, and carbon monoxide from the air:

1. Areca Palm (Chrysalidocarpus lutescens)

Also called the “Butterfly Palm”. An upright houseplant that is somewhat vase shaped. Specimen plants can reach 10 to 12 foot in height. Prefers a humid area to avoid tip damage. Requires pruning. When selecting an Areca palm look for plants with larger caliber trunks at the base of the plant. Plants that have pencil thin stems tend to topple over and are quite difficult to maintain.

2. Lady Palm (Rhapis excelsa)

Also called the “Lady Palm”, this durable palm species adapts well to most interiors. The Rhapis are some of the easiest palms to grow, but each species has its own particular environment and culture requirements. The “Lady Palm” grows slowly, but can grow to more than 14′ in height with broad clumps often having a diameter as wide as their height.
