$180 for a pothos, and probably a small one at that, is a bit on the pricey side.

Do the leaves wave around like fan blades?

When they have one that can also do the windows...

They don't need to. You would be surprised at the convective air circulation that occurs naturally. No forced air required. Slowly but surely wins the race.

Here's another rather amazing technology:

https://www.sherwin-williams.com/homeowners/products/superpaint-air-purifying

The paint industry got hit hard by a combination of bad Gulf weather reducing their petroleum based raw materials, mainly resin, and the pandemic with all the people staying home having nothing to do but create record demand on paint suppliers. S-W has a major plant in "East Baltimore" producing 150,000 gallons daily, and they sell every drop of it. Not sure about now, but not too long ago they were rationing how much they would sell to individuals.
I can't speak for the air purifying performance but I can say their Superpaint line is very long lasting and lives up to all their claims- I don't see that they charge any more for the VOC absorbing version either. And buy one or two gallons and they always let you have additional gallons at substantial discounts- like 50%.

There are self-cleaning glass windows:

Why overkill with a houseplant?

We have such glass on a conservatory roof. It does work reasonably well,
but the north facing slope gets noticeably more dirty than the south facing slope.
This is of course not surprising as the cleaning mechanism is photo-catalytic.
It needs cleaning twice per year as the self-cleaning is not perfect.

Houseplants are easier to replace than SETS of windows. Especially if you
have LOTS of glass in your home!

I looked at installing photochromic/electrochromic windows and
realized it was easier just to close the blinds! :<

The weak point in modern windows is that blasted inert gas seal leaking.

Well at least it cut the cleaning job by half. That's its main selling feature.

Yup. And some don't even have a thermal break between inner and outer pane.

Although it is being sold as a Pothos aka Devil's ivy it looks to me
like the plant shown in the picture above is a sansevieria.

Their website shows the right species of plant IMHO

https://neoplants.com

However, the main claim to fame of this plant is that it is practically
indestructible and a common US houseplant ripe for exploitation of the
worried well. The claims made are unsupported by evidence and stink of
marketing bullshit.

The common spider plant will do exactly the same job almost as well for
next to nothing (and is endorsed by NASA for so doing).

https://en.wikipedia.org/wiki/Chlorophytum_comosum

Sansevieria also scored pretty highly in these old NASA tests:

You want a telegraph plant for that. Codariocalyx motorius

It's real, and they have big backers with scientific expertise:
https://www.genengnews.com/topics/genome-editing/synthetic-biology/neoplants-hopes-to-curb-indoor-air-pollution-with-bioengineered-house-plants/

white paper:
https://cdn.sanity.io/files/y50klc11/staging/90a83797763b9dc7a054ea6587a46d38cb08dcbf.pdf

Their technology does more than just remove the pollutants, but metabolizes them into nutrient material. And its the whole system of plant + the soil mix microbiome + that special planter pot for circulating air and watering.

Those old NASA tests are what's bullshit. They achieved their air purification by sucking air through the potting soil. Well- of course that's going to trap airborne pollutants. Duh.
