Humidifiers
By Dr. Meg Christensen | Updated October 2025
Humidifiers can keep your lungs and skin happy during dry months, and these keep your home mold-free, too.
Blueair Humidifier Air Purifier Combo
I recommend several of Blueair’s air purifiers because they’re transparent about their CADR results, tested by many third party outlets, and are affordable. Their 2-in-1 Purify + Humidify combo is rare, because it actually has decent air purifying capabilities, with CADRs in the 200s— a measure of how well it filters particles from your room. Usually, combo units just can’t do both purification and humidifying. (Dyson doesn’t disclose their CADRs and their machines are much spendier, though they do look nice.) This is a great way to add moisture and purify your air all at once, and if you go with the filter subscription, its arrival automatically reminds you to make sure the unit is clean and remains mold-free.
Moss Lab makes the best looking humidifier, and it’s effective, safe, and functional too! While I’m skeptical that the moss meaningfully purifies the air (you’d need 680 houseplants worth of moss for that), their moss filters are actually easily changeable, can absorb and release excess water, and are paired with a cotton wick. It also functions as a mood light, terrarium, or aroma diffuser, as well. Great biophilic design. It is small— I have this on my office desk— you might want to consider a larger humidifer for bigger spaces.
Is the Canopy humidifier legit? While I’m not wild about the optional “aromas,” which contain artificial fragrance, I am into most everything else about it: it’s small, affordable, and dishwasher-safe, so it can be easily sterilized. They also have a few clever functions that help inhibit water stagnation and mold build up. The filter has an antimicrobial in it, which I normally am against, however, you’d almost never touch it, and in the case of mold prevention, I’m more in favor. Comes in attractive colors in several sizes. Overall a good choice!
Carepod was designed by a doctor frustrated with the bacteria and mold that quickly builds up on most humidifier filters. As a result, it doesn’t have a filter, and instead is made with dishwasher safe stainless steel so it can be washed and sterilized. It was also designed without nooks and crannies, so there isn’t any place for hidden mold to accumulate. Has warm and cool mist settings. So cool.
