In the event of an emergency, the U.S. maintains a stockpile of crude oil known as the Strategic Petroleum Reserve. Its main goal is to safeguard energy security when disasters strike—think sanctions, severe storm damage, or war. It can also do a lot to ease the pain of sudden price jumps when supply gets disrupted.

The Molekule Air Pro comes from a brand that pays keen attention to aesthetics. It and the app have that Instagrammable, muted-modern look that countless clothing and bedsheet brands emulate these days. That style doesn’t come cheap as the Air Pro costs over $1,000 and requires $140 filters. The company came under fire for and had to stop making many of its claims about its filtration system, which may have led to it filing for bankruptcy in 2023. Molekule is still able to tout its patented photoelectrochemical oxidation, which the company says destroys pollutants at a “molecular level.” In my tests, it performed almost as well as the others in improving VOC and PM2.5 levels. But it’s also very loud: When auto mode kicked the fan into high gear, it would make me tense. Also, I found the unit often indicated “bad” or “very bad” levels when my two monitors indicated the air quality was actually pretty good.
