The Top 5 Plants To Purify Your Home During ISO

The Top 5 Plants To Purify Your Home During ISO

Written by Josh Douglass – Greenhouse Co.

As we all bunker down during the Coronavirus COVID-19 pandemic it’s more important than ever to ensure our homes remain healthy.

‘Sick building syndrome’ results from the build-up of toxins released by synthetic building materials. This is more of an issue in sealed office buildings than it is in our homes but hey, unless you live in a Yurt your home is still made of synthetic materials and they’re still releasing toxins.

So in these times of Corona crisis, replace your friends with plants!

It’s long been known that indoor plants not only make a room look and feel better but also create a healthy living environment.

Plants increase oxygen levels and remove toxins produced by synthetic materials as well as our own bodies. They can also prevent the build-up of dangerous mould spores and act as a natural humidifier, reducing the spread of airborne disease.

What is Sick Building Syndrome?

Modern buildings are designed to be energy efficient; this can block the flow of air to and from the outdoors. Added to this, artificial building materials such as glues, plaster, paint and synthetic fabrics release toxic chemicals such as benzene, toluene and formaldehyde, in a process known as ‘off-gassing’.

You can also add us humans to this mix, who also exhale ‘bioeffulents’ which add to the toxicity of the air that we literally live and breathe in.

The air-purifying properties of plants.

Many plants have the ability to absorb chemicals through tiny pore like structures on their leaves called stomata; the same structures are used to absorb CO2 for use in photosynthesis.

Once absorbed by the leaf these chemicals are either metabolized (broken down) for use elsewhere in the plant (for example to create complex chemical compounds such as alkaloids or translocated to and exuded by the roots where they are then broken down by soil microbes).

The more plants you have in a space, the more stomata you have therefore the greater the air purifying power!

Indoor plants as a defence against mould spores.

Wet and poor ventilated areas of the home create the perfect environment for the build-up of mould. Moulds reproduce via spores, tiny reproductive particles that can easily become airborne.

These mould spores, if inhaled can be harmful to our health. Asthma sufferers in particular can be severely affected by mould spores.

“Dangerous air-borne microbial levels were found to be 50% lower in a plant filled room”.1

Indoor plants that have evolved under the canopy of damp rainforests have created a natural defence against the build-up of mould.

These plants emit ‘allochemicals’ to attack competing organisms like mould.

Selecting the right indoor plant is key to reducing airborne mould spores in the home. So choose a plant that has adapted to life in the humid, low light environments of the tropical forest understory.

These include ferns and many plants in the Araceae family (Philodendron, Anthurium, Monstera, e.t.c).

Plants, the natural humidifier.

Many allergy sufferers use humidifiers to reduce dry air in the home.

Dry air can cause irritation of the sensitive membranes in the nose and throat leaving sufferers more susceptible to the effects of air pollution and attack from airborne pathogens.

Whilst humidifiers need to be cleaned regularly to ensure bacteria doesn’t grow inside the machinery, plants can naturally increase the humidity of their immediate environment by releasing water vapour through their stomata. 

Unlike your humidifier, your plants are increasing the humidity while cleaning the air!

Which plants are best for air-purification?

As general rule plants with a greater leaf surface area have a greater ability to purify air than others. The types of chemicals removed from the air also vary from plant to air-purifying plant. According to the NASA clean air study Philodendron plants were among the most effective at removing certain toxins from their surroundings.

To help you out we’ve collated some of the best plants for creating clean air in your home. Consider these your new best friends to hang out with during your self-isolation. Plants love to listen so you can share all your self-isolation stories with them too!

  1. Monstera ‘Taurii’

The unique and popular Monstera deliciosa ‘Taurii’ looks great and is probably one of the easiest houseplants you will ever care for. Some even say they thrive on neglect. So, if you’re a rubbish plant parent these guys are for you!

Native to the tropical rainforests of southern Mexico down to Panama their big glossy-green, swiss-cheese like leaves can turn any room into a jungle.

2. Philodendron Crassinervium

These super easy to care for plants are a native of southeast Brazil with long lance-shaped leaves that point upwards with a large, very obvious midvein. The midvein is used to store water for periods of drought that occur during the dry season.

3. Anthurium Schlechtendalii

Another big, beautiful bird’s nest Anthurium found from Mexico to Costa Rica! It produces very large, dark green leaves with undulate (ruffled) edges a prominent midrib and leaf veins. The spadix (inflorescence containing heaps of tiny flowers) is a deep purple with a green spathe (leaf or petal looking thing around the spadix) and can be nearly 30cm long! 

4. Philodendron Squamiferum

Philodendron Squamiferum is sometimes known as the Red Bristle Philodendron due to the red, bristle-like hairs that grow on their elongated petioles (leaf stem). A very interesting and unusual looking climbing Philodendron with big lobed leaves that is very easy to grow. 

5. Mini Monstera

These super easy to care for plants are a native to southern Thailand and Malaysia. They get their common name of Mini Monstera from the similarity in leaf shape to that of Monstera deliciosa.

Although they are in the same family (Araceae) and have a very similar habit and care requirements, they are actually part of the genu Raphidophora, not Monstera.
