Features To Consider With Humidifiers
Now that you've taken a look at our picks for the top 15 best humidifiers, check out our list below for some key features to look out for when shopping for your air humidifier.
Naturally, the size of your space and of the humidifier itself should affect your decision making. Most humidifier manufacturers will state the square footage their product can humidify on the packaging or label.
If you want to run your humidifier overnight or while you're working from home, you won't want a noisy machine disturbing you. Generally, humidifiers with built-in fans will be noisier than without. Look for humidifiers with auto-shut-off or night modes if you must have the fan but don't want the noise.
Cold Mist vs. Warm Mist
Another feature you'll notice when shopping for humidifiers is that some will expel cool mist whilst others incorporate a heating element that burns away bacteria and expels warm moisture. Whilst warm moisture might be appealing, humidifiers with a heating element aren't recommended for children or pets due to burning risks.
If you don't want to be refilling the water tank constantly, look out for running times and tank capacities. Humidifiers with an auto-shut-off feature are great if you have a smaller tank or running time as these won't waste energy powering the humidifier when it's out of water.
When considering the tank design of the best humidifiers available, you're going to want to think about a few aspects: firstly, how easy is it to remove/replace the tank? Is there a wide opening for refills/cleaning? Is it easy to get in and clean the tank to clear away any bacteria, mold, or minerals?
Ease Of Use
Similarly to the above, think about how easy it will be to use/maintain your humidifier. Some come with a useful display panel so you can easily keep an eye on how your humidifier is doing, while a clear tank is great for you to check the water levels without having to take the thing apart. Remember, a humidifier is meant to improve the quality of your life, so you're not going to want one that takes hours out of your life.
Again, think about how easy it will be to maintain your new humidifier. For example, if your humidifier comes with an air filter, how frequently will this need to be changed? Whilst warm mist humidifiers tend to stay cleaner for longer as they boil off of some bacteria, all humidifiers need regular cleaning. The manufacturer's instructions should include details on how to clean and maintain your humidifier.
In addition to the above considerations, there are some bonus features you might want your humidifier to offer. Things like a humidistat will allow you to monitor the humidity levels in your home (a safe and comfortable humidity level is usually between 30-50%). Some will also offer additional benefits such as air filters, UV light filtration, or a demineralization cartridge to help you minimize the amount of maintenance required and improve the overall air quality while adding moisture.
Types of Humidifiers
There are a few different types of humidifiers to look out for, and the type that's right for you will vary between households.
An evaporative humidifier is a type of cool mist humidifier that uses a filter to pick up water from the reservoir beneath it. A fan then blows air over the filter which picks up moisture as the water evaporates. The mist is then propelled from the humidifier, producing a cool-mist across your home. These types of humidifiers do require regular cleaning of the filter and reservoir as bacteria and minerals from the water can build up on the surface and you should also replace the filter periodically.
These are usually cheaper than warm mist humidifiers, but you should also consider the cost of replacing your filters and additional noise from the fan.
The quietest humidifier type available, ultrasonic models use a vibrating disc to evaporate water molecules and release them as a mist into the air. Some may include a fan to help propel the mist further, but this may make them noisier when running.
One of the major benefits of an ultrasonic option is that they don't have any filters that need changing/replacing so they're a really low maintenance choice.
An impeller works similarly to an evaporative humidifier as it works by using a rapidly spinning disc that sends water to the in-built diffuser. Here, water is transformed into moisture droplets that are dispersed into the room as mist.
With no filter, you don't need to worry about replacements and there's less to clean. You should be wary of bacteria however and use distilled water.
Also known as warm mist humidifiers, this option heats up the water to the boiling point and expels steam. By boiling the water first, a warm mist humidifier is great for reducing bacteria and microbes, ensuring only healthy moisture is released.
Heating elements tend to use more electricity than cool mist humidifiers and they aren't recommended for use around children or pets.
Finally, if you don't want a portable humidifier, you might want to consider having a whole-house or central system professionally installed. There are three types of whole-house humidifiers: flow-through, reservoir, or steam, and an installation professional should be able to help you establish which is best for your home.
These are the lowest maintenance option and can deliver moisture to every area of your home. The downside is the considerable expense associated with the installation and you should be sure to check the warranty.
If you do go for this option, you might also want to consider giving some other aspects of your home an upgrade. Why not check out our buying guides for the best carbon monoxide detectors or the best through wall air conditioners while you're at it?
Q: How can I check the current humidity level of my home?
Many humidifiers come equipped with humidistats that allow you to keep an eye on the humidity levels in your home. Alternatively, you can purchase air quality monitors separately. Check out our buying guide for the best air quality monitors here.
Q: Should humidifiers run all night?
If you intend to run your humidifier overnight check the reservoir is full to avoid burn-out, otherwise it’s 100% safe to run overnight and can help improve your sleep, allowing you to wake up feeling fresher and free from congestion. Keep an eye out for models with an auto-shut-off that will switch off the machine automatically if the reservoir runs dry.
Q: Do humidifiers kill airborne viruses?
Humidifiers can be really effective in fighting viruses and flu by improving humidity levels and air quality. By keeping your throat and nasal passages hydrated, you may also notice reduced congestion and sinus inflammation. Features such as UV light filtration or air filters are particularly useful as they ensure only the cleanest vapors are released into the air.
Q: Which is better, warm or cool mist humidifier?
Both warm and cool mist humidifiers are equally effective when it comes to adding moisture to the air. As we’ve mentioned already, a warm mist humidifier shouldn’t be used around children but they can be better for reducing bacteria and require less maintenance.
Q: Is it safe to use tap water in a humidifier?
Because tap water contains mineral deposits that can promote the growth of mold and bacteria, even if your tap water is safe to drink it’s not recommended to use it in a humidifier. For best results, use distilled, demineralized, or purified water and clean the tank regularly.
Q: Is a humidifier good for the lungs?
Dry air is awful for your skin and respiratory systems, so adding a humidifier to your home is great if you experience problems such as dry skin, allergies, coughs, nose bleeds, sinus headaches, or cracked lips, among other issues. By adding moisture to dry air, you can open up the airways, making breathing easier and more comfortable.
You must be careful to clean out your humidifier frequently, however, as a dirty humidifier can expel bacteria, minerals, and even mold into the air, which will cause problems for your lungs and body. That said, as long as your machine is properly maintained you should experience a wonderfully clean feeling right down into your lungs almost as soon as you plug it in!
Q: How easy is it to maintain a humidifier?
Generally, humidifier maintenance is pretty easy, although it can become more difficult if the water tank has been badly designed or if you leave it too long between cleanings.
Humidifiers should always come with maintenance instructions from the manufacturer which will let you know how and how frequently to clean your machine for the best effects, as well as how often the filter (if one is included) will need to be changed under normal circumstances.
