A roomful of plants can be a breath of fresh air… quite literally. A study by NASA in 2015 illustrated the prodigious air-cleaning ability of the humble houseplant.
However, there’s a new study on the block and it’s arguing that a few indoor plants may not be as air-purifying as we’d first imagined.
Researchers at Drexel University have recently found that it takes a whole lot more than a couple of succulents perched on your coffee table to actually make an impact in the purity of the air in your home.
They agree that plants do indeed clean the air – albeit at a very, very slow pace. To illustrate that for you; you’d need around 93 plants per square foot of space for them to effectively function as an air-purifying system. That’s a lot of plants you’d somehow have to keep alive.
So, if freshening up the atmosphere in your home is the main reason why you're getting more plants, you're probably better off with an air purifier instead. But, that’s not to say that your precious pothos isn’t helpful in other ways. Studies have found that houseplants can help improve mood and mental health while reducing stress. They’re also super ‘grammable. Win-win?
