But First things First: Who Needs a Top Fill Humidifier?

Top-fill humidifiers are especially helpful for people with a busy schedule. When you’re back from work, the last thing you want to do is disassemble the unit to clean or refill it. Therefore, with a top-fill unit, all you’d have to do is remove the lid and clean the tank, or just fill it with water.

It’s also useful when you are not at home and you want your child to fill it up, for example. This is easy to do even for children (above 7-8 years of age).

However, the ones benefitting the most from these devices are elderly and disabled people. Those dealing with conditions like arthritis or other issues related to mobility can fill out the tank without difficulty. Thus, they can enjoy the moisturizing effect that these humidifiers can bring.

People who are not able to lift heavy water tanks will also appreciate a unit like this. They can just fill the water tank near their bed too, without having to carry it from a place to another. It’s a huge benefit to consider if you’re in a similar situation.

Benefits and Drawbacks of a Top Fill Humidifier

Honeywell humidifier in useEven the best top fill humidifiers will have their drawbacks. Knowing them before purchasing the device will help you decide if it’s the right unit for you or not. That being said, here are some pros and cons of top fill humidifiers.

  • Pros

The main and most obvious benefit of a top fill humidifier is the fact that it can be easily refilled and cleaned. Unlike other types of humidifiers, you don’t have to remove the tank for these tasks.

All you have to do is remove the top lid of the unit, and you can just pour the water inside. The same goes for cleaning – you will immediately gain access to the inside of the tank and you can clean it.

Another amazing thing when it comes to these devices is the fact that you won’t necessarily have to carry them to another place to refill them. Instead, you can refill them next to your bed if you want to. Just bring the water with you and refill the tank whenever necessary.

If the tank has a wide opening, it will also make sure that you can reach every corner when you need to clean it and wipe off the excess water.

  • Cons

Now, it’s important to know the drawbacks too.

First of all, tanks can be removed sometimes, even when talking about a top fill humidifier. But this may cause the water to drip out of the tank and spill on the furniture, the floor, or any surface that happens to be underneath. This requires you to be more careful when refilling the unit – and even place a towel underneath all the time.

Bacteria and fungus may also start to form in the tank, and you may have to start cleaning it more often. Some tanks have wider openings than others and if you get one with a smaller opening, cleaning may become more difficult.

Aside from the tank, the lid may also start developing bacteria and fungus underneath, so that part of the device will have to be checked frequently to keep the device safe to use. If you don’t, then the water released into your atmosphere in the form of mist will be less healthy to inhale.

At this point, it would be great to learn about the best product in the market according our expert reviews.

Things to Consider in the Best Top Fill Humidifier

TrueMist top-fill humidifierIf you want to find the best top fill humidifiers, you should be aware of some specific factors. Here are some of the most important ones:

  • Warm Mist vs. Cool Mist

Do you prefer warm or cool mist? Even with top fill humidifiers, you can choose between these two options and buy a humidifier that fulfills your temperature requirements.

When you’re looking for humidifiers, think about the temperature in your house and the usual weather where you live. Is it hotter, or colder? If it’s hotter and you’d like your environment to be a little colder, then a cool-mist humidifier will be the way to go. The only thing to consider is the fact that these may be noisier compared to warm-mist humidifiers, as they use a fan to cool the water.

On the other hand, warm-mist humidifiers will be more fitting when you have colder temperatures and would like to warm up a little bit while moisturizing the air. They are great and less noisy than cool-mist units considering no fan is included.

However, they may not be the best when you have curious children wandering around the house, as these units can get pretty hot. A heated-up humidifier can easily become dangerous around children or pets if tipped over, so keep this in mind when shopping.

  • Sink vs. Bedside Fill

There are top fill humidifiers that you can just take to your sink and refill. Basically, you detach the tank and take it to a sink, and let water pour inside. Then, you take it back onto the base of your unit.

But you should think well whether you need this type of humidifier or one that can be filled at the bedside using a jug. If you have elderly or disabled people in your house or happen to be one, then going for a bedside fill one will be the best choice.

  • Tank Capacity

You can’t buy a device like this one without considering the tank capacity. Top fill humidifiers will come with a variety of capacities, and you have to consider your room size when making the decision. Pick a size that is suitable for you and your needs.

Also, if you are opting for a device with a detachable tank, then think about the fact that you will have to carry it a lot, and it may be heavy if it is too large.

  • Filters

The filtration system is important because it helps filter out the bacteria and other contaminants from your water tank. If you want to inhale healthier mist, consider picking a top fill humidifier with filters.

  • Ease of Cleaning

Some humidifiers are easier to clean than others as they either have a detachable tank or a wide opening. Look for one that makes cleaning and maintenance easy unless you want deposits to affect the water quality in the tank.

  • Materials

It’s important to choose a top fill humidifier that lasts for a long time. That being said, look at the materials it was made from. Avoid low-quality ones if you’re looking for a long-lasting unit and consider sturdier ones, even if they boost the price.

  • Noise Level

For a good night’s sleep, you have to consider a humidifier that is quiet enough to let you rest properly. In general, the noise level is specified in the features or the reviews so look for that.

  • Portability

Portability is especially important since you may have to move the device from a place to another for refilling or cleaning. Look for a humidifier with a carry handle to make your job easier.


Are you still looking for more information on top fill humidifiers? If that’s the case, you may find it in these commonly asked questions and their answers.

Q. Do I need to unplug the humidifier each time I refill the tank?

A: Yes, you have to unplug a humidifier before you refill it or clean it. This is to keep yourself safe, and also to make sure the unit is maintained properly and lasts for longer.

Q. Where do I add essential oils in my top fill humidifier?

A: The place where you add the essential oils all depends on your humidifier. For example, if you wish to add essential oils in your top fill humidifier, you can just put them in the water tank. When you fill it up with water, add some drops of essential oil and you should be able to enjoy the amazing aromas while the device humidifies the air.

But some models have a separate tray where you can add the oil, and it will still make sure to release nice smells into the air.

Consider the type of humidifier you have and check out the manual that comes with it if you want to make sure you add the essential oils in the right place.

Q. How do I clean and maintain a top fill humidifier properly?

A: If you want to clean a top fill humidifier, you have to detach the tank or take off the lid to reveal the inside of the tank. Look for any leftover water and get rid of it.

Then, make a mix of white vinegar and water. This should contain half water and half vinegar, and it helps get rid of mineral buildup or hard water deposits. So, pour the mixed liquid into the tank and shake the water for around 30 seconds.

If you live in hard water areas, then you might be interested in the best humidifier for hard water.

Then, unscrew the filter cap and fill it with lukewarm water. Screw the filler cap and let the water sit like that for like 30 minutes. Afterward, rinse the filter cap and the tank and set them aside to dry.

Make sure to clean the base too, using the same type of mixture, pouring it inside and letting it sit for 30 minutes. Take a brush that usually comes with the product and try to clean any deposits on the surface. Then, pour the mixture down the sink and clean the remaining moisture with a soft microfiber cloth.

Q. How do I know which humidifier size will fit my room best?

A: Generally, manufacturers mention in their specifications what room size the humidifiers are suitable for. Some are good for larger rooms while others will be better for smaller ones. The tank capacity will be a good indicator too – the larger it is, the more space it can cover.

Q. Are top fill humidifiers generally messy?

A: Not necessarily – it depends on the particular product and how you handle it. Some may start leaking or water can drip out of them when you remove the tank.

A: Some beloved brands for top fill humidifiers include LEVOIT, GENIANI, raydrop, Homasy, and TaoTronics.

Q. Do I need a filter with my top fill humidifier?

A: It’s not necessary, but it is recommended. Water may contain bacteria or fungus so it’s important to get rid of it before it makes its way into the air. A filter will help with that, so it’s best to have filters with your top fill humidifier.

Q. Can you add more water instead of just refilling it?

A: No. Doing that could be very risky because when water sits in the unit, it may become a breeding ground for bacteria. This is why the tank has to be emptied and cleaned properly before you get to use it again. Never add more water to the existing one.
