Air Purifying Plants

Air Purifying Plants
Use of Plants to Purify Indoor Air

Introduction
• In offices, homes, and other indoor areas,
poor air quality can both cause health
problems and make existing health problems
worse.
• The U.S. Environmental Protection Agency
(USEPA) currently ranks indoor air pollution
as one of the top five threats to public health.

Introduction
• Indoor air pollution results from the release of
chemical vapors and the suspension in the air of
particulates such as dust and microorganisms.
• In response to increasing Energy costs and the
need to conserve energy resources, buildings and
homes have been designed to be more energy
efficient. Thus, many offices and new homes have
tighter construction, sealing the building from the
outside air. This makes it easier for indoor air
pollutants to accumulate to dangerous levels. With
people spending up to 70–90 percent of their time
indoors, long-term Exposure to indoor air
Pollution can cause various health problems.

Introduction
• Air pollution can build up in any confined space, but
gases from synthetic materials used these days to
construct or furnish offices and homes can, among
other factors, result in “sick building syndrome.”
• People who are hypersensitive to the pollutants can
develop serious symptoms including eye, nose, and
throat irritations, allergies, asthma, blurred vision,
dizziness, fatigue, headache, skin irritation, nervous
System disorders, and upper respiratory and sinus
congestion.

Sources of emissions of air pollutants
• The major sources of indoor air pollutants are
combustion by products, Building materials,
household products and chemicals, and bio-
effluents.
• Combustion by products include carbon
monoxide, nitrogen and sulfur dioxides,
formaldehyde.
• Combustion by-products Are produced by gas
ranges, cook tops, water heaters, clothes dryers,
smokers, and internal combustion engines turned
on in enclosed spaces.

Introduction
• Household products and chemicals that
cause indoor air pollution include furniture
waxes, paint strippers, adhesives, cleaning
products, disinfectants, degreasers, and
cosmetics. Some of these products release
chemicals into the air during use, whereas
others emit chemicals as they age, dry, or cure;
this is known as out-gassing.

Ways to Improve Indoor Air Quality
• There are various ways to reduce indoor air
pollution and improve air quality. Increasing
ventilation and air exchange with the outside
will help prevent the accumulation or
reduce the amount of air pollutants indoors.
• Exhaust fans can be Installed in the kitchen
and bathrooms, and air filters such as high-
efficiency particulate air filters, which have
a carbon filter component, can be used.

• Combustion appliances should be vented
directly to the outside and regularly
inspected, cleaned, and maintained.
• A by product of propane gas combustion is
carbon monoxide. The house should be well
ventilated when cooking or heating with
propane.

• Use only wood products that are
formaldehyde-free or have low
formaldehyde emissions. Seal the surfaces of
wood products with surface finishes that are
water-based.
• Select low-emission building products and
carpets. Avoid household products that have
hazardous vapors, and do not store
hazardous products in the home.

House Plants help Clean Indoor Air
• While developing technologies that allow
humans to live in closed environments such
as the International Space Station, NASA
discovered that plants help reduce volatile
organic chemicals/compounds (VOCs) and can
be an efficient way to filter the air in living
compartments.

• The Plants for Clean Air Council and wolverton
Environmental Services have tested different
houseplants for their ability to remove various toxic
gases such as formaldehyde, xylene/toluene, and
ammonia.
• Plants absorb volatile organic compounds from the air
into their leaves and then translocate them to their root
zone, where microbes break them down. Microorganisms
in the soil can use trace amounts of pollutants as a food
source.
• Some organic chemicals absorbed by plants from the air
are destroyed by the plant’s own biological processes.

• Plants add aesthetic and biological comfort to
interior paces. When plants are added to
rooms, relative humidity can increase and
particulate matter (dust) accumulation can
decrease. Increasing relative humidity has a
relaxing effect on people, and removing dust aids
by reducing potentially allergy-inducing particles.
• Reducing particulate matter in a room may
also be beneficial to computers and other
electronic equipment by limiting the amount of
dust collecting on circuit boards and clogging.

• During photosynthesis, carbon dioxide is taken
in through plant foliage, and oxygen is
produced and released by The Plant as a by
product.
• At night or when no photosynthesis is taking
place, plants, like people, respire and Give off
carbon dioxide.
• Volatile photochemical released by plant
leaves appear to be important in controlling
airborne microbes and mold spores in
surrounding air.

• Plants release water vapor via transpiration
through the leaves and into the air, raising
humidity.
• High transpiration rates create convection
currents that cause toxin-laden air to be pulled
down into the soil around the roots, where
microbes in the soil break down the gases into
a source of food and energy. Air also moves into
and out of leaf stomata (pore-like openings).

How Houseplants Help Clean Indoor
Air

NASA List Of Best Air-Cleaning Plants
• NASA did a Clean Air Study, that found which
plants are effective at removing benzene,
formaldehyde, trichloroethylene, xylene, and
ammonia from the air – chemicals that have
been linked to negative health effects like
headaches, dizziness, eye irritation, and others.
• Dr. B. C. Wolverton led the study about 27
years ago and although this research is quite
old, it is still regarded by many as the most
comprehensive and accurate to date.

The Air Cleaning Experiments
• Most people have heard at some point that
house plants are good for your health
because they can clean, filter and purify the
air of various toxins and pollutants.
• A lot of people know that this has been
proved by science, although most people don't
know about the actual studies or which plants
are best for the job.

• The National Aeronautics and Space
Administration (NASA) began to think about
future life-support systems so humans could
live on the moon and other planets that the
ability of plants to filter and purify the air
was exposed in full detail.

• NASA proposed that if humans travelled to
inhospitable planets then small biospheres would
need to exist in order to support them, much like a
spacecraft provides a suitable environment for its
passengers as they travel through space.
• The issue however was that at the time spacecrafts
could only be used for short periods due to the quick
build up volatile organic chemicals, coming both from
the people themselves as well as various equipment and
machinery used on the craft.

• Between 1980 and 1984 NASA proved plants in
sealed test chambers that were exposed to
volatile organic chemicals could remove them
from the air. Including formaldehyde which is
found in, or used to produce, a multitude of
everyday products, from fabrics and furniture to
tobacco smoke and gas stoves.
• In 1984 people were very excited by NASA's
findings and as a result they funded significant
research looking at house plants and their air
purifying abilities.

• Dr Bill Wolverton was one of the scientists
brought on board to help research and
study the effects of houseplants on air
quality in contained spaces and produced
some of the most popular and commonly
referenced research papers about the topic.

The List of 50 Plants
• The list is ranked in order of plant
effectiveness in a typical home according to
Dr Wolverton. So the 1st plant in the list
(Areca Palm) is the most effective and the 50th
(Kalanchoe) is the least

The Areca Palm
The Areca Palm
• The Areca Palm or Butterfly Palm is a
relatively easy care indoor houseplant that has
much going for it. Its attractive nature has been
awarded the Royal Horticultural Society's
Award of Garden Merit, which for a plant
grown more commonly indoors than out, is a
pretty rare feat.

The Areca Palm
• The Areca Palm took first place among 50
plants that were tested for their ability to
filter the air around scoring highly in all
categories meaning it was ranked the best
houseplant at cleaning the air in homes and
offices

The Areca Palm
• Benefits: It is known for being one of the
better performers in purifying the air.

Lady Palm (Rhapis Excelsa)
• The lady palm, or Rhapis excelsa, is a small
fan palm that can do exceedingly well
indoors under the right conditions.

bamboo palm or miniature fan palm, is the
best suited of all the fan palms to indoor
cultivation.

• Bamboo Palm is a useful indoor palm
because its adaptability to the environment,
exotic look and anti-pollutant abilities.
• It is very common in malls, offices, homes
and courtyards. The slow-growing, small
palms are ideal for shaded borders and as
indoor potted plants. The bamboo palm
provides attractive foliage for outdoor beds
and borders.

• Benefits: According to NASA, it removes
formaldehyde (carcinogen, cancer-causing
substance associated with most chemicals,
plastics, cigarettes and off-gasing) and is also
said to act as a natural humidifier.

The Rubber Tree Plant
• The Rubber Plant could be the houseplant
for you if you want a tough plant which can
reach staggering heights within a few years.
While its size can still be tamed some what,
you have to keep in mind it will eventually
require a certain amount of space.

• Rubber Plant as one of the very best
houseplants to clean the air.
• It also scores really well with resistance to
pests and diseases and has a high
transpiration rate which increases the
humidity of the room it lives in.

• While rubber plants (Ficus robusta) are grown
as easy-care houseplants, they also improve
indoor air quality, according to studies
conducted by NASA. Their large leaves can
absorb airborne chemicals and break them down,
rendering them harmless.
• They absorb exhaled carbon dioxide and
convert it to breathable oxygen. Rubber plants
also eliminate bacteria and mold spores in the
air.

Dracaena Janet Craig
• Janet Craig is one of the most popular
Draceanas used indoors, likely due to it’s
ability to grow in low light and tolerate
considerable dryness.

• Dracaenas are one of the plants used in the
NASA Clean Air Study and has shown to
help remove Formaldehyde.

• The Dracaena (or Dracaena deremensis)
places fifth on NASA’s ranking. According
to data it can remove Formaldehyde, at a rate
of 1,328 micrograms per hour. It also removes
Xylene.

• It's also one of the top rated plants for
removing air pollutants from the air and
because of its almost insatiable appetite for
water it pumps out large amounts of water
vapor into the nearby air, thereby
increasing humidity.

Peace Lily
• The NASA study focuses on common air pollutants that
tend to be given off by manmade materials. These are
chemicals that become trapped in the air in enclosed
spaces and can be bad for your health if breathed in too
much.
• One of these chemicals is Benzene, which can be
naturally given off by gasoline, paint, rubber, tobacco
smoke, detergent, and a variety of synthetic fibers.
• Another is Trichloroethylene, which can be found in
paint, lacquer, glue, and varnish. In other words, it’s
commonly given off by furniture.

Peace Lily
• Peace lilies have been found to be very
good at removing these two chemicals
from the air. They absorb the pollutants
from the air through their leaves, then
send them to their roots, where they’re
broken down by microbes in the soil. So
this makes using peace lily plants for air
purification in the home a definite plus.

The Yellow Corn Plant
The Yellow Corn Plant
• This very popular houseplant often goes by the
name Corn Plant, or by its official Latin name

air purifier, and it tops the list.
• Syngoniums absorb pollutants into their
leaves, and the toxins go to the root zone
where they are transformed into nutrients for
the plant.

Deffenbachia
(Dumb Cane / Leopard Lily)
• Dieffenbachia or (to use its common name) Dumb
Cane has a bad reputation The truth is that Dumb
Canes are poisonous, however it rarely kills human or
animal.
• All parts of the plant have lots and lots of microscope
needle-shaped calcium oxalate crystals and when some
unfortunate animal (or person) chows down, they end
up with a painful and swollen mouth.
• In some cases the swelling is so bad it causes the
victim to go silent for inability to talk, this is where
the common name of Dumb Cane came from.

Deffenbachia
• NASA tests confirm that plants clean
formaldehyde and other toxins from the air.
We have formaldehyde in our homes from
paper towels, garbage bags, tissues, carpet
backing, and floor coverings.
• Dieffenbachia removes not only
