We don't cover every smart home crowdfunding project here on The Ambient, but we do like the look of the Matr air monitor and purifier, which is live on Kickstarter now.
It claims to use a nanotechnology filter system, called Photocatalytic Oxidation, that can get rid of household pollutants up to 300x smaller than traditional purifiers. Matr is designed to eliminate VOCs, bacteria, fungus, mold, dust, pollen and more.

The filters don't need to be replaced, as they're washable, which saves money in the long run and it's also quiet at noise levels of 30dB.
Matr will send information about the air quality in your home to your smartphone, as you'd expect, and there's also Alexa voice controls so you could use a voice command like, "Alexa, ask Matr Purifier about my indoor air quality."
You can pledge ¬£149 now to get a Matr air purifier - the compact device comes in white and black models - with shipping set for June 2019. There's also a wearable tech component in the form of the Matr tracker which senses and displays temperature, humidity, pressure and VOCs and wirelessly charges on top of the air purifier.
It's all the work of UK-based startup founded by Matthew Rowe and Xavier Crane, and the project target is a pretty modest ¬£100,000.
