Petapixel seems to like the idea, and I'll admit I'm intrigued. Not $220 intrigued though, but I'm not exactly in a light pollution heavy area either.
Petapixel Lonely Speck PureNight is a premium glass light pollution reduction filter designed by Lonely Speck. Made of a special didymium glass, PureNight reduces the transmission of light from sodium vapor lamps, one of the most prevalent sources of light pollution on our planet. Resulting images will have truer colors and improved contrast when compared to images influenced by light pollution. Didymium glass greatly reduces transmission of yellow and orange light in the 575nm to 600nm wavelengths, the same wavelength of light that is emitted by high pressure sodium vapor lamps. Sodium vapor lamps are most commonly used on street lights and industrial lighting fixtures and so they are one of the most prevalent sources of light pollution for astrophotography.

I use one on my telescope, they certainly do work.
Look around on version astronomy websites, there are a few types for regular camera lenses, actually maybe I'm wrong but I think there way be one that sits between the camera and lens. If I get a chance I'll look it up, I may be misremembering |

That's cool. I live in one of the most light polluted region of the country, I only get to see real night sky when travelling, and often then it's still not great depending on destination and conditions.
That filter makes an obvious difference. |

$220 is cheap in the photography world, going to look into this.
