Some wit remarked at the YouTube video page that a simpler way is to open the window. But seriously, if you’re in the bowels of a high rise cube farm, there ain’t no stinkin’ window.
And at a place I visit frequently in the L.A. area, I can open up windows and the private patio screen door, but the outside air brings in road dust and car exhaust.
So it’s a HEPA filter or these plants for clean indoor air.

“Tulsi has been used for thousands of years in Ayurveda for its diverse healing properties. It is mentioned by Charaka in the Charaka Samhita, an ancient Ayurvedic text. Tulsi is considered to be an adaptogen, balancing different processes in the body, and helpful for adapting to stress. Marked by its strong aroma and astringent taste, it is regarded in Ayurveda as a kind of “elixir of life” and believed to promote longevity.”
“Tulsi’s extracts are used in ayurvedic remedies for common colds, headaches, stomach disorders, inflammation, heart disease, various forms of poisoning, and malaria. Traditionally, tulsi is taken in many forms: as herbal tea, dried powder, fresh leaf, or mixed with ghee. Essential oil extracted from Karpoora Tulsi is mostly used for medicinal purposes and in herbal cosmetics, and is widely used in skin preparations due to its anti-bacterial activity. For centuries, the dried leaves of Tulsi have been mixed with stored grains to repel insects.”
