A humidifier in your home helps to alleviate many health problems associated with dry air. Adding moisture to the air in your home helps prevent dry skin, nose bleeds, dry coughs, and alleviates snoring. With some humidifiers, you can add a few drops of essential oils for extra health benefits and a pleasant aroma.

MistAire XL Ultrasonic Cool Mist Humidifier for Large Rooms

The MistAire is one of the best filterless humidifiers on the market and is a popular seller. It’s simple but stylish design makes it suitable for most homes and office spaces.

What I like about the MistAire is that it is a perfect size for large rooms, and has a long operation time of between 10 and 24 hours.

If you have a large room to humidify, you don’t want to keep checking on the water level and refilling. The MistAire filterless humidifier holds 1 gallon of water, and you have the choice of two mist controls. You can choose a single or dual output option- to help the humidifier run for longer before needing to be refilled, use the single output option.

Once the water level drops to a certain point, there is an automatic shut-off safety feature that turns off the humidifier. It also turns off the humidifier automatically when the water tank is removed.

Some humidifiers are noisy when operated, but the MistAire has a whisper-quiet operation which also makes this a great choice for a baby nursery or office space.

There is an optional night light, which is great if you’re using this in a child’s bedroom. Children find the night light comforting. There are three color settings available.

The humidifier has a 5-year warranty.

hOmeLabs Cool Mist Humidifier Diffuser

The HomeLabs cool mist humidifier is a great option for those wanting to use a humidifier in a baby’s bedroom.

I’ve chosen it as one of the best humidifiers without filters, because it has a very long run time of up to 30 hours! There is a water capacity of 1 gallon.

You can set a timer for 1 hour, 4 hours or 8 hours, and there are two variable mist options: high and low. There is also a sleep mode.

This is also a great humidifier for a baby or toddler’s nursery or bedroom because it has a child lock, great for added protection. There also isn’t a night light, which means that your child won’t be distracted by bright colored lights like the ones featured on other humidifiers.

If you like using essential oils, you can add a few drops of essential oils that will be diffused by the humidifier.

There is a water level indicator panel so that you can clearly see how much water is left in the tank.

The simple but elegant square design means that the humidifier suits any décor style.

Please contact the supplier directly for warranty information.

There’s an auto shut off feature which switches off the humidifier once it runs out of water, so you don’t have to worry about always having to check the water level.

The best feature of the Rosewill is that there is a 360 degree adjustable nozzle, so you can choose where you want the nozzle to point.

TaoTronics Humidifier

The TaoTronics is a great humidifier to use in a baby’s bedroom or nursery. It has some great features which makes this humidifier a preferable choice if you want something that will help you sleep better, and not keep you awake with annoying lights or noises.

The humidifier has a water tank capacity of 2 liters, and will automatically shut off once the water level is empty.

The best feature about this humidifier is that it has a sleep mode available. This switches off the LED power light and reduces the sound from the humidifier. You can leave it on all night, knowing that it won’t run out of water and will help make your room comfortable for you to sleep in. This is especially great if you’re using it in a baby’s nursery or toddler room. You want a humidifier that will help your child sleep.

There is a 360 degree nozzle, which means more even mist dispersion throughout the room. There is also a low and high mode, so you can set how much mist you want the humidifier to disperse. On the low setting, the humidifier can operate up to 24 hours without needing to refill the water tank. On the high setting, operation time is around 8 hours, which still makes it good to use overnight.

There are no annoying, bright LED lights on this humidifier! The only thing that lights up is the LED power light, so that you can see what you are doing when switching the humidifier on and off.

OPOLAR Digital Humidifier with Humidity and Timer Control

The Opolar digital humidifier is an excellent choice for those wanting strict monitoring of humidity levels and a humidifier that has a timer control.

The best feature, and why I’ve chosen the Opolar as one of the best humidifiers without filters, is that it has an in-built humidity controller. You can easily find out what the humidity level is in your room, and adjust the settings of the humidifier so that you can increase or decrease humidity in the room.

This is a great humidifier to use in a small to medium room, so it would be great for a bedroom or a small living area.

The water tank has a capacity of 3 liters, which is around 0.8 gallons. It can operate up to 26 hours before needing to refill the water tank.

There are three different mist settings, and there is a rotating twin nozzle for even dispersion of mist.

I really like the stylish design and color of the humidifier. You can switch off the LED lights at night so that the humidifier doesn’t disrupt your sleep. The humidifier also has a whisper quiet operation, which is great if you’re using it in a baby’s nursery or a toddler room.

All in all, a great humidifier without a filter.

Vicks Warm Mist Humidifier with Auto Shut-Off

Vicks is a brand most people know and trust, so naturally the Vicks Warm Mist Humidifier is one of the most popular and best-selling humidifiers without filters.

It has a 1 gallon water capacity and can operate up to 12 hours before needing to be refilled. This makes it a great choice for bedrooms and other medium/large living rooms or office spaces.

There is only one mist setting available, which you cannot adjust.

There is an automatic shut off feature which switches off the humidifier once it has run out of water.

If you want to add oils to the humidifier, you can add Vicks vapor oil to the humidifier and it will disperse the oil with the water. This is similar to using an essential oil diffuser.

Since this is a warm mist humidifier instead of a cold mist humidifier, the humidifier can be a breeding ground for bacteria, viruses and germs. Even though this is a filterless humidifier, you use a cleaning ball inside the humidifier. This cleaning ball ensures that the water is free from bacteria and germs.

The Vicks Warm Mist Humidifier has a 3-year warranty available.

What’s the difference between a humidifier with a filter, and a humidifier without a filter?

 

The main difference between a humidifier with a filter and a humidifier without a filter is the ongoing cost. A humidifier without a filter means you don’t have the ongoing cost of replacing filters. But you will usually pay more to purchase a humidifier without a filter than one with a filter.

While not having a filter in your humidifier will save you money in the long run, you need to ensure that you clean your humidifier on a regular basis. It is recommended that you change the water inside the humidifier each day.

Once a week you should clean the unit using vinegar, to remove any potential mold, germs or dust.

Humidifiers with filters do not have to be cleaned as often as those without filters.

Another difference is that humidifiers without filters tend to disperse more dust and other contaminants into the air. This is because there is no filter within the humidifier to filter the contaminants before they are dispersed.

As discussed in our post HERE, our water contains many different particles and contaminants. One way to remove these is to filter your drinking water. If you do not use a filter for your drinking water, then the water that you put into your humidifier will contain these particles. In a humidifier without a filter, they will be dispersed into the air. Sometimes this results in a white dust from the mineral deposits found in the water.

This will not be an issue if you already use a water filter that can filter out minerals and other fine particles. If you are interested in finding out more about water filters or want to purchase one, you can do so via THIS LINK.

One final difference between a humidifier with a filter and a humidifier without a filter is the operation noise. Most humidifiers with filters use a fan within them to cool the water down, and so are noisier than those without. Most humidifiers without filters do not have this fan, and so are quieter.

A Humidifier With A Filter Or A Humidifier Without A Filter: Which Is Better?

A humidifier with a filter is better for those with respiratory problems who do not use a water filter in their home. This is because the mold, bacteria, germs and dust is filtered out before the mist is dispersed. This is not an issue if you already use a water filter in your home.

A humidifier without a filter is better suited to those who prefer a quiet operation, such as when it is being used in a baby’s nursery or a child’s bedroom. It is also better suited to those who do not want to pay the ongoing costs associated with replacing filters. The negative aspects of having a humidifier without a filter can be eliminated by using a water filter in your home.
