Can I Buy a Filterless Humidifier?

Humidifiers like cool mist humidifiers and warm mist humidifiers can do a world of good for your home and for your health but they require some ongoing maintenance to ensure they are operating properly. One of the most time-consuming and expensive aspects of humidifier maintenance is dealing with the filter. Not only do you need to occasionally clean the filters on many models of humidifiers, you will also likely need to invest in replacements every few months.

The good news is humidifier manufacturers recognized the inconvenience and expense of dealing with filters and developed humidifiers that did not need filters. For many people, these new filterless humidifiers and filterless air purifiers were what put them over the edge when it came to investing in this home health tool. They might have avoided the use of a humidifier for years, figuring it was better to go without than to deal with a dirty, unhealthy filter, or the expense of replacing it. Now, however, you can enjoy all of the benefits of a humidifier without the trouble of a filter.

Benefits of a Filterless Humidifier

Using a filterless humidifier offers a variety of benefits. Many of these benefits are similar to traditional humidifiers, but there are also a number of benefits provided by filter-free devices that are not found in the older filtered devices. Benefits of filterless humidifiers include:

  • Quiet operation—nobody will be woken up at night by the sound of the running humidifier
  • Filter-free technology that does not require replacement filters
  • Improved health
  • Antibacterial protection that prevents mold and mildew growth
  • Variable mist settings that allow adjustment for individual comfort
  • Improved health of skin and a boost to the body’s immune system

Filterless humidifiers are able to keep the air moist and clean the same time. The machine puts moisture back into the air—just as a filter-having humidifier—but it works without a filter. The air still stays clean, but there are no removable filters inside of the device. Instead, these filterless humidifiers use electrostatic charge technology to clean the air and push it back into the room in the form of a mist.

What Types of Filterless Humidifiers are Available?

There are several different options available for homeowners who want to invest in filterless humidifiers. Your choice will depend on your budget, the size of the area in which you intend to use the humidifier, and your personal preferences. Currently, five different types of filterless humidifiers are available, including:

  • Evaporators
  • Central filterless humidifiers
  • Steam vaporizers
  • Impeller filterless humidifiers
  • Ultrasonic filterless humidifiers

Central filterless humidifiers are placed into your home’s air conditioning unit or heating unit and blow moisture through the vent system. Impeller humidifiers are the most child-friendly of the units available and blow cool mist, which helps when babies or young children are croupy or suffering from chest or nasal congestion. Steam vaporizers moisturize the air without being a huge financial investment. And ultrasonic humidifiers work much like impeller humidifiers, but product the mist with the help of an ultrasonic vibration.

How Do I Know My Home Needs a Humidifier?

One of the easiest and most obvious ways to tell if your home could benefit from added moisture via a humidifier is your own comfort. If you’re experiencing nose bleeds for no identifiable reason, your skin is itchy, tight, and dry, or you and your family are suffering from frequent head colds, it’s likely an indication you could use a humidifier.

A few other symptoms that could be linked to needing a humidifier include:

  • Waking up with a dry, scratchy throat
  • Nasal and chest congestion
  • Chapped lips
  • Dry, nagging cough
  • Rapidly aging skin
  • Dry, brittle hair and nails
  • Pets scratching without any diagnosis of fleas or other skin irritants

It’s also a good idea to invest in a hydrometer that can tell you the moisture level in your home and let you know if the air is getting too moist—something that can damage your home.

Choosing the Best Filterless Humidifier

Shopping for a filterless humidifier can feel a bit overwhelming, especially if you’ve never purchased one before. It’s a good idea to do a bit of research before you buy and to have a clear understanding of what you want. Most people even set a budget so they know what they can afford in a home humidity system.

Whole house humidifiers can be very expensive but are often the best choice for a home. On the other hand, if a whole house model busts your budget, you can get a great humidifier that solves your dry air problems for a reasonable cost.

It’s also a good idea to familiarize yourself with the pros and cons of filterless humidifiers before you buy. You might have your heart set on not needing replacement filters, but this doesn’t mean filterless humidifiers are perfect. They do have their downside and the main con is that they need to be cleaned on a daily basis. If you’re running your humidifier every night, this can turn into a lot of work so make sure you choose a model that’s easy to clean.

Some people have concerns about how hygienic filter-free humidifiers are, but the truth is most are just as safe as humidifiers with filters. Just make sure you are investing in a quality machine and that you clean and maintain it as is recommended by the manufacturer.

What are the Best Filterless Humidifiers on the Market?

There is a variety of brands and models of filterless humidifiers on the market.

Crane Drop Shape Cool Mist Humidifier

The Crane Drop Shape Cool Mist Humidifier is one that we found easy to use and to clean. It provides a cool mist and is one of the more affordable options available. You clean it by adding a small amount of vinegar, shaking the unit, and then allowing it to soak for about 20 to 30 minutes. There’s no need to disassemble anything or wash any individual components.



Air-O-Swiss AOS 7147 Ultrasonic Humidifier

Another option is the Air-O-Swiss AOS 7147 Ultrasonic Humidifier. It uses high-frequency vibrations to generate a mist that is micro-fine. The mist immediately evaporates into the air, so you never need to worry about anything in the room getting damp from condensation buildup.  This humidifier features a pre-heating function that allows you to warm the mist to 104 degrees before it blows into the air. It has a demineralization cartridge so you don’t need to worry about the white mist that some cheaper humidifiers emit because the minerals are extracted from the water before it is turned into mist.

Vicks UV 99.999% Germ-Free Humidifier

The final option on our list that’s reliable and easy to use is the Vicks UV 99.999% Germ-Free Humidifier. Like the name says, it takes antibacterial clean to the highest level possible. It’s a warm mist humidifier, so it might not be great for when you are sick with congestion, but it’s a great option for warming your home in the winter and keeping the air from getting too dry. The germ-free claim is accomplished by using a UV chamber that kills germs and prevents mold from forming inside the unit. It also features a medicine chamber that allows you to distribute medicinal mist into the air that can help with stuffy noses and sore throats.

These are just a few of the filterless humidifiers available for use today. Many people are upgrading to filter-free humidifiers and enjoying the effects of moisturized air in their homes without concern for replacing filters on a monthly basis.
