These are usually the ones with the largest range, as they are embedded within a home’s A/C unit. This makes them expensive, however, and they cannot really easily be installed as an afterthought. Homeowners may need to replace or revamp their entire home’s environmental control, but they make for a smart choice if installed from the get- go. In the case of renters, they’re usually off- limits: installing them entails more tinkering than the standard lease allows you to do.
Also known as wick humidifiers or warm mist humidifiers, these gadgets basically warm up water and release its soft mist into the air. These are a great option for those in colder climates, as they can help support the heating system during winter. They also have the advantage of being very easy to clean, which prevents them from becoming a nesting site for mold and fungi. However, they may be unsafe for homes with children or pets, as the heat they give out could cause burns.
These humidifiers are equipped with an internal water container and a disk-shaped diffuser, which sends out the water droplets into the air as a cool mist. They are silent and very energy-efficient, but they usually have a low range. Their filters need regular replacing.
A higher-tech variant from classic impellers, these use ultrasonic vibrations to spread moisture around the room. They use more energy than standard impellers, but require no filter replacement,

What to Look for in the Perfect Humidifier?
Choosing the right humidifier for your home will depend largely on your needs. You can do away with some of the legwork by looking at this checklist; it should help you cover all major aspects behind the purchase:
If you have any children under 10 or any small pets, then it’s best to steer clear from any warm mist or heat-emitting models. Nothing bad will happen from sitting next to them, but too much skintight contact could result in burns.
Smaller apartments, especially when not made from wood, can be easily served by a smaller range humidifier. Smaller or “tabletop” models are also ideal for allergy sufferers who just need to increase a few percentage points of water content while they work or lounge around their living room. On the other hand, whole-room humidifiers have ranges between 600 to 1200 square feet; ideally, measure the room first and then add 200 square feet of leeway.
In addition to regular cleaning (which at the very least, you can always handle by yourself for free), the upkeep of the humidifier will be determined by two factors: their energy consumption and whether they require filter replacement. A quick search though Amazon will help you take into account the cost of replacement filters.
Silent mode, timers, and aromatherapy capabilities are nice perks to have, but they are not essential for all users. This is a consideration best left for after you’ve covered all your other bases.
