While it’s more affordable, it is missing some of the bells and whistles that the best of the best air purifiers offer, like an automatic air sensor; this might be a trade-off that you are more than willing to accept. If you are after a high-performing, excellently priced option for a modest-sized space, you’ll be more than pleased with this air purifier. The Molekule Air Mini+ is designed for small spaces, like a bedroom or home office. In our testing, it performed far worse than our pick for those scenarios, the Levoit Core 300—which costs about $100, versus the Air Mini+’s typical $350 or more. On its medium setting , the Air Mini+ reduced smoke levels by just 58.7%, versus the Levoit’s 92.6%. And even on its highest setting, on which it produced an intolerable 66 decibels, the Air Mini+ only reduced the smoke by 91%; the Levoit captured 97.4% on high, while measuring at 54 decibels.

I don’t often use the night light, and am not entirely sure why it exists, unless you leave it in the middle of a walkway and want to avoid tripping over it in the dark. But, ultimately, my Levoit is an affordable HEPA air purifier, and I feel better and breathe better with it in my home. I’d highly recommend it for anyone looking for a quiet, effective and affordable air purifier. The air also seems noticeably clearer, and I haven’t had to dust nearly as much. Overall, I feel that I’m enjoying a higher quality of life and that my air purifier has definitely played a large part in that.

You should rinse out your humidifier tank after each use and ensure that the water tank completely dries before replacing it in the unit. While manufacturers will each have their own guidance for cleaning and caring for a particular unit, we recommend thoroughly washing your humidifier tank with a mild dish soap. You can also wipe the exterior of your humidifier with a damp cloth to prevent dust build up on the fan components. Most filters can just be rinsed with water, and they should be replaced every 1 to 3 months, based on how often you use your humidifier.
