Types within the line
Room humidifiers serve a single room, and they are the general type within the air line. Warm-air humidifiers add warm moisture to the air, and cool-air humidifiers add cool moisture: the difference is the temperature of the moisture, which changes how the air feels and which rooms suit each type. Cold-air humidifiers are the cool-air type described by temperature, and they suit rooms where warm moisture would be unwelcome.
Steam humidifiers add moisture as steam, by heating water until it vaporises. Evaporative humidifiers add moisture by evaporation: air passes over a wet surface, and the water evaporates into the air naturally. The evaporative guide explains evaporation in general terms. Ultrasonic types, where the storefront lists them, add moisture by vibration rather than by heat or evaporation, and they belong to the air line's type family as displayed.

How to choose a type
Start from the room and its needs, not from the humidifier. A bedroom, a sick room, a dry office and a nursery each have different needs, and the type should fit the room, not just the air. Warm-air types suit rooms where warm moisture is welcome; cool-air types suit rooms where it is not. Steam types suit rooms where steam is acceptable; evaporative types suit rooms where natural evaporation is preferred.
Do not choose by a single figure. A coverage figure alone does not describe a humidifier: the room it serves, the way it adds moisture, and the maintenance it needs all matter. The inquiry should name the room and the need, so the supplier can confirm the right type from real stock information. The humidifier selection guide and the room-sizing guide explain the distinctions in full.
Separate from the household humidifier line
Air humidifier and household humidifier appear as separate categories on the storefront, and they are kept separate here: each has its own page, its own description, and no hierarchy between them is stated, because none is evidenced. A buyer who needs one should inquire about that one, not assume the other covers it.
A buyer who needs an air humidifier should read this page and its guides, and inquire through the bulk humidifier inquiry page naming the air line. A buyer who needs a household humidifier should read the household humidifier page instead. The two lines are not interchangeable, and an inquiry that names the wrong line will receive an answer for the wrong product.
What to confirm in an inquiry
Name the room and the need the humidifier must serve, the quantity you have in mind, and the market you sell into. Ask for the specification for the exact type, the minimum order quantity for your order, the lead time with its meaning, and the certificates that apply to your market, by name, with documents attached. The bulk humidifier inquiry page lists these confirmations in full.
Before payment, confirm the minimum order quantity and lead time for your order. Certificates are available upon request.
About this category list
The category list on this site follows the storefront categories as displayed. The storefront list may be truncated on the page, so the list here may be incomplete; if a category you need is not shown, name it in your inquiry and the supplier can confirm whether it is available.
The air humidifier line is described here at category level only. No models, no parameters and no performance figures are stated, because none are evidenced. A buyer who needs a specific model should name it in the inquiry, where the supplier can confirm or decline from real stock information.
