When I originally started looking for an air purifier, I sought out a sleek machine that could help curb all the pollen that incessantly drifts through my windows during spring. Living on a tree-lined street is great, but dealing with all the green spores (and stuffy nose)? Definitely a bummer. After bringing Molekule’s Air Mini+ purifier home, I quickly realized the compact machine did much more than filter out those pesky flecks and dust. (More on that later.) The only caveat? It’s pricey. The smaller version is usually $500, and upgrading to the larger Pro (it can filter spaces as large as 1,000 square feet versus 250 square feet) will cost you $500 more and then some.

Personally, I’ve found the price tag to be worth it. Case in point: My bedroom shares a wall with my neighbor’s kitchen and, like clockwork, I’m greeted every morning by the sound of them opening up their microwave door and pressing a few buttons to start it up. Shortly after, I can smell their breakfast. But just a few days after setting up the Mini+, that unwelcome aroma all but disappeared. And I didn’t do much beyond the initial setup. Unboxing was a breeze; I just had to remove the little guy from its cloth bag and plug it in. I placed it right on my nightstand and still had enough room for my table lamp and coaster for my nightly glass of water. 

Through the app, I selected the Auto-Protect mode, although there are five different fan settings to choose from. While it initially powered up to scrub the air the first day, its loud whirring lulled to a soft hum (just 39 decibels) that’s quieter than a sound machine. That is, until I’m dowsing my hair with product to either style or blow-dry it. In those moments, the fan increases to the highest speed in order to quickly rid the air of all the pollutants I personally added. Now it’s not only the one room in my apartment that needs less routine cleaning, it smells fresher, too. Stale, musty scents are rare there, even after a long trip away. 

While I love the Mini+ for my less-than-200-square-foot bedroom, there are a couple of perks to going with the Pro, too. Molekule recently launched new-and-improved sensor technology and reports; before, you could only check what your air purifier was filtering out on a day-to-day basis, but now the brand will provide you with weekly trends over a four-week period, revealing when quality dipped and pointing out the main culprit behind it—be that VOCs, CO2, relative humidity, or other pollutants. Other reasons, if you aren’t quite sold, include a 30-day, risk-free trial and free shipping. So you may never have to guess what exactly it is you’re breathing in again.
