Why Use a Filterless Humidifier?
You may be wondering why you would choose a filterless humidifier over a filtered one, considering the risk of impurities. However, filterless humidifiers are sometimes cleaner than their filtered cousins. This is because the filter in the filtered model can get very dirty and if not replaced regularly, it can contaminate the mist.
Now, this doesn’t mean filterless humidifiers emit dirty mist. Due to new technologies, these humidifiers can clean the moisture before it leaves the nozzle. Here are a few other advantages of filterless humidifiers:
- Quiet: Most filterless humidifiers use ultrasonic technology to create a fine mist. This is much quieter than evaporative units. The lack of filters also makes them quieter.
- Easier maintenance: Filters become dirty and eventually need to be replaced or cleaned. Removing the filter can be rather tricky, depending on the type.
- Cheaper: Although the initial price might be the same as a filtered humidifier, you’ll save in the long run. You’ll be ditching the expensive cost of replacing filters regularly.

Finding the Best Filterless Humidifier
There are many advantages to opting for a filterless humidifier. Still, you should choose wisely. Here are a few points to consider when finding the best filterless humidifier:
Tank size plays an important role no matter what type of humidifier you’re buying. The tank capacity will determine how long the humidifier can work before needing to be refilled.
Large and small tanks each have their pros and cons, so you must consider your needs. For people who need the humidifier to run for long hours at a time, a large capacity is required. However, if you only need it to run for a few hours at the office, a small tank is sufficient.
Maximum Mist Output
The maximum mist output refers to how many ounces of mist the humidifier is able to produce per hour. This number can give you a very clear idea of just how effective the humidifier is going to be.
Many brands will give you a minimum and a maximum; these refer to the settings as well. So if you want the maximum output, the humidifier has to be at the highest setting.
Cleanliness plays an essential role in maintaining your filterless humidifier. Because there’s no filter, bacteria and germs can build up within the tank and tube. Most humidifiers will come with cleaning instructions.
However, this can cause another issue: tank access. Opening the tank and cleaning it is often easier said than done. Some humidifiers have a wide opening of 4 inches while others are barely 3 inches. This can make it tricky to get your hand inside with a sponge to clean it.
Don’t Forget The Tube
