Researcher Kamal Meattle describes how an arrangement of three common houseplants placed in specific spots can measurably clean the air in a home or office. It is a short TED talk based on his work in a plant-filled building.

HN commenters cite it in threads about indoor air quality, CO2 and houseplants as a cheap, low-tech approach.

From this thread "How Trees Calm Us Down": link Japanese researcher describes (with control group) the interesting affects of walking in a forest. link Indian researcher describes side affects of indoor plants on health esp. air quality. ▶ this video I'm incorporating some of these concepts into my tiny house design e.g. a (truly ingenious design using mirrors!) terrarium and an hinoki ofuro, together with natural daylighting. A poster called mantesso offered up this interesting paper: Here's the original study from NASA, Interior Landscape plants for indoor air pollution abatement : link

When I flew into Heathrow last year, I was amazed by how visible the pollution was- over central London, there were no clouds (there were clouds around the outskirts) but this vague, blue haze was quite noticeable. Although compared to Shanghai, London is really clean, if you live in Shanghai you keep your windows permanently shut and run an air purifier 24/7: link > I'd recommend anyone living in a city to invest in a good air purifier from BlueAir or IQAir (if you can afford it). Another, more environmentally friendly option: ▶ this video Also basil plants are a natural mosquito repellent, might not be an issue in the UK though.

Uh, do you mean house plants? There is also a Ted talk about taking this to an extreme, which does seem to anecdotally work: ▶ this video

I meant high tech gadgets, but sure How to grow fresh air | Kamal Meattle ▶ this video link On a second thought, indoor DIY growbox is probably can be considered as such device.
