Think again.<\/p>\n\n\n\n<p>In a 1980s study, NASA announced a list of indoor plants with air filtering properties, equipped to purify our air and boost our health. In fact, they also found that certain houseplants can remove up to&nbsp;<a href=\"https:\/\/spinoff.nasa.gov\/Spinoff2007\/ps_3.html\" target=\"_blank\" rel=\"noreferrer noopener\">87%<\/a>&nbsp;of air toxins in just 48 hours. Considering that over<a href=\"https:\/\/www.rhs.org.uk\/advice\/profile?PID=949\" target=\"_blank\" rel=\"noreferrer noopener\">&nbsp;4 million<\/a>&nbsp;people die worldwide due to indoor air pollution, this was a crucial discovery that has changed many lives for the better.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Certain houseplants can remove up to&nbsp;<a href=\"https:\/\/spinoff.nasa.gov\/Spinoff2007\/ps_3.html\" target=\"_blank\" rel=\"noreferrer noopener\">87%<\/a>&nbsp;of air toxins in just 48 hours<\/p>\n<\/blockquote>\n\n\n\n<p>To help you purify your indoor space, we\u2019ve compiled a selection of our favourite plants from NASA\u2019s recommended lineup.

While famed for its unique leaves and uses in the food and skincare industries, this powerhouse has even more goodness to offer.<\/p>\n\n\n\n<p>The plants that made the final cut of NASA\u2019s list share one thing in common: they\u2019re capable of eliminating VOCs (volatile organic compounds) from the air. Aloe vera has been proven to remove benzene and formaldehyde from indoor spaces, two VOCs typically found inside the home. In fact, aloe vera even develops dark spots if there are high levels of certain VOCs \u2013 the plant itself serves as a natural air quality monitor.<\/p>\n\n\n\n<p><strong>Want to know how to care for your Aloe Vera?<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Water sparingly to avoid oversaturation \u2013 they store water in their leaves and are designed to require very little of it to function.<\/li>\n\n\n\n<li>Provide the plant with as much light as possible by placing it in a window-lit area.<\/li>\n\n\n\n<li>Fertilize once a year with a phosphorus-heavy houseplant mix.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0630\/2580\/7529\/files\/Screen_Shot_2022-11-08_at_4.58.17_PM_480x480.png?v=1667919514\" alt=\"Three panels of indoor palms: Top left shows a large, bushy Lady Palm in a copper-colored pot; Top right features a smaller palm in a dark gray pot; Bottom left shows a slender palm in a silver metallic pot.\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Broadleaf Lady Palm<\/h3>\n\n\n\n<p>Next up on NASA\u2019s selection of air purifying houseplants is the incredible broadleaf lady palm. This elegant species doesn\u2019t actually exist in the wild, designed and brought to life by Chinese cultivators.<\/p>\n\n\n\n<p>Broadleaf lady palms are well-known for their air-filtering skills, removing four key toxins from the air: carbon dioxide, formaldehyde, xylene and ammonia. Since clearer air and more oxygen has been proven to boost mood and concentration, this plant is undoubtedly an important one to have around your home.<\/p>\n\n\n\n<p><strong>How to care for a broadleaf lady palm:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sunlight is essential, but avoid direct light if possible.

Look no further than the Barberton daisy. Also known as a gerbera daisy, Barberton daisies are well-known for their air filtering properties and can survive both outdoors and in. If you bring them indoors in the autumn months, they\u2019re likely to survive the winter and reflower in the spring.<\/p>\n\n\n\n<p><strong>Caring for your Barberton Daisy is pretty simple:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Intense midday sun may age flowers prematurely, so avoid direct sunlight.<\/li>\n\n\n\n<li>Keep soil moist but not soggy, especially during the warmer months.<\/li>\n\n\n\n<li>Use a natural fertilizer to keep roots and leaves looking healthy.<\/li>\n<\/ul>\n\n\n\n<p><strong>Top Tip:<\/strong><\/p>\n\n\n\n<p>Did you know that you can make your fertilizer at home AND&nbsp;<a href=\"https:\/\/foodcycler.com\/blogs\/sustainability\/the-rotten-truth-food-waste-doesn-t-break-down-in-landfills-and-other-myths-busted\" target=\"_blank\" rel=\"noreferrer noopener\">save the planet<\/a>&nbsp;in the process?
