Bionaire humidifiers convert liquid water into a water vapor, where it mixes with the air to create moisture. While most of Bionaire's products are standalone units appropriate for single-room use, the company also offers products designed to humidify an entire home.
Bionaire manufactures cool-mist and warm-mist humidifiers, and some units that offer both. Some humidifiers can only work for small rooms, while others are appropriate for larger spaces. In addition, different units have different water storage capacities. Potential customers will want to ensure that they pick a unit of an appropriate size and understand how often water and filters need to be replaced.
