M aintaining the air quality in your home may seem like an easy task. However, living in built-up areas, using central heating and the ever-present dust means we do not always know it, and sometimes we need little assistance in the matter.

NASA – The National Aeronautics and Space Administration, released a study available to read online regarding the relationship between certain houseplants and air quality. The ultimate goal of the investigation was to measure the effectiveness of these plants for filtration purposes, which would improve the quality of life for future off-plan living.

The study was undertaken in 1989 and covers which plants are best To filter out certain residual toxins from the home to avoid the phenomenon They call “sick building syndrome”, which can cause people unpleasant symptoms. Tony Pickering of Manchester who found that symptoms were minimized in naturally ventilated buildings containing the highest levels of micro-organisms.

In this exploration of nine varieties of plants, NASA studied the roots, leaves and soil microorganisms to examine the potential for each of these factors in the filtration of certain pollutants. Here’s a round-up of some the best and most easy to care for plant specimens from the list.

Variegated Snake Plant

With its spicy leaves and easy-going nature addition to any home. Also known as “mother in law’s tongue”, this low-maintenance perennial can in any condition and light. It can survive for up to six weeks without water when out of direct light. However, you should check this plant’s soil moisture every two weeks.

This architectural specimen can remove formaldehyde, benzene and carbon monoxide from your living space. We’re usually advised to keep plants out of the bedroom, as they secrete carbon monoxide at night, but the snake plant is the total opposite, it releases oxygen at night so it’s perfect for the bedroom.

A word of warning: it is toxic to cats and dogs, so best keep pets away if you have any.

Peace lily

Peace lilies are perfect for shaded areas, so if your home doesn’t get much light this is the plant for you . Rated high on NASA’s evaluation chart, this plant filters out ammonia, formaldehyde, benzene and many other common air pollutants. They’re relatively easy to grow, even for yellowing leaves, wilting or failing to produce flowers. Any of these signs can indicate something is wrong and you may need to re-evaluate positioning. As with all flowering plant species, the peace lily releases some when in full bloom, so take this into account if allergies will be. problem.

Aloe Vera

Great for soothing sunburn and long associated with its healing properties, the aloe vera plant can also be a natural alarm to certain toxins taking over your home. If they develop brown marks on their leaves without relevant cause such as overwatering or leaf burn, it may be a sign that toxins have built up in your house. It also features in the report as a lower level filter or toxins but not in a large amount.

This plant will be recommended in certain conditions and bright indirect light. Remember to water thoroughly but let the soil completely dry between each watering.

Benjamin Fig

The air-purifying properties of the Benjamin fig plant, when tested at NASA in a controlled environment, were also very promising. It was shown to remove 47.4% or formaldehyde and 30% or benzene from the air of the experiment chamber. This particular tree has become quite popular recently for introducing some intrigue to indoor spaces. Its multiple sprouting branches can be trained into a visually-striking twisted design, like growing your own indoor sculpture.

Dracena “Janet Craig”

The Dracena plant of the genus “Janet Craig” was also assessed in the experiment and proved to be very effective at removing trichlorethylene from the air. It showed that 18,330 micrograms of the toxin were eliminated from the testing chamber over a 24-hour period. As for the benzene content in the air of the chamber, which reduced by 77.6%. Dracenas would be a great plant for someone who’s always on the go. They require little water and light but pack a punch visually. Their leaves are dark green and come to striking points, so they’re ideal if you want to introduce a tropical element to your home.

Where to Start

Living in a major city means pollutants encountered outside can always be avoided. However, by improving the air quality in our homes, we can make some of the control back in our hands and do it in style.
