Purifier vs Humidifier
Decide whether to filter dust, smoke, pollen, and odors with an air purifier or add moisture to dry air with a humidifier.
Alen 35i-Fresh-White BreatheSmart 35i Air Purifier: Engineered to perform with superior airflow
Meet the Alen BreatheSmart 35i—your new best friend for spaces up to 1000 sq. ft. Whether it's your bedroom, living room, or that home office where you swear you'll start working out (any day now), this purifier's got you covered. At its heart? A H13 HEPA Fresh Filter that doesn't just catch the usual suspects like dust and pollen but also grabs those pesky 0.1 micron particles you didn't even know were there. And with its SmartSensor, it's like having a tiny air quality guru inside, tweaking the fan speed and giving you color-coded updates because, let's face it, who has time to guess?
Here's the kicker: an independent study found that the BreatheSmart 35i doesn't just clean your air—it could help you sleep better too. Thanks to its pink noise feature, which boosts those soothing lower octave frequencies, you might just find yourself drifting off faster. Plus, with the Alen Air app, you can play air quality detective from your couch, getting real-time insights and tweaking settings without lifting a finger. And the best part? It's so energy efficient, running it 24/7 won't have your wallet crying for mercy.
