Amazon has the BlueDri AS-550 Air Scrubber on sale for nearly half off based on camelcamelcamel with Prime.
Fakespot gives it an A on reviews
I’ve purchased one myself and this is a phenomenal price for anyone in the construction industry. I don’t know how many people actually need an air scrubber, but if you do its pretty hard to beat this price.
For those that don’t know what this is, it’s basically an industrial air purifier.
