best-filterless-humidifiers

The importance of humidifiers in increasing the humidity levels in a home should not be overlooked. You may already be familiar with how traditional humidifiers function – they incorporate a basic system that includes a filter. This filter needs to absorb water, which is then distributed into your room as fresh, moist air by a fan, enriching the room’s atmosphere.

However, the problem with this type of humidifier lies in its filters. First, you will need to keep changing the filters, a cumbersome and costly process. Second, dirty filters can fill your room with contaminants and disease agents if not regularly cleaned.

That is why we have researched the best filterless humidifier options on the market for you:

While we have researched and compiled what you see above, you have another task, you have to choose EXACTLY what suits your needs. Before you buy the right or best filterless humidifier for winter, your bedroom, or other setups, ensure you check on the following features.

Mist Type

Fortunately, in this guide we talked about cool mist filterless humidifiers, however, we didn’t discuss warm mist filterless humidifiers – which basically pre-heats water to kill bacteria before diffusing it (the mist) into the atmosphere. So, depending on your needs, select what is suitable for you.

Water Tank Capacity

This is very vital as it determines the effectiveness and the success of the humidification process of your home or room. This factor, along with the size of the room you are looking to moisturize, dictates the number of hours the humidifier will take to cleanse your space.

That being said, a large capacity tank means more hours of operation and better results in a big room. The same goes for a smaller tank, which is the best for small and medium-sized rooms.

Area of Coverage

Consider checking what area the unit you’re buying can cover, 160 sq.ft., 200 sq.ft., 400 sq.ft., 500 sq.ft., and so on. Some only cover small areas while some are designed to cover large areas. You will definitely need to match the device to the respective area before making a move. Don’t overbuy!

Look for a Humidistat

Ensure that the unit you are purchasing has a humidistat – or a setting that controls the level of humidity so it remains within the correct range – so it doesn’t go either side of both extremes.

Noise Level

You also want to find out how many decibels of sound the model emits, they all make a sound, but some models are outrageously noisy. There are quiet humidifiers on the market, just keep in mind that quiet humidifiers ensure a peaceful sleep.

Extra Features

High-end humidifier models come with a variety of features. Normally, these are the most efficient in moisturizing a room, but the attached price-tags may be a hamper, although many humidifiers are generally not very expensive.

Warranty

This is very important – it represents the quality of the device you want. Ensure the warranty information is clear and understandable. Some brands can be sneaky on this matter, so it’s good to be vigilant.

What is the technology behind filterless humidifiers?

Well, first, these humidifiers do not have and do not use filters like the traditional ones you know. Instead, they utilize a combination of methods to purify water before releasing the mist.

For example, some incorporate antibacterial materials, while others use electrostatic charge technology, and for other types such as the warm mist models, you will hear of the pre-heating mechanism that purifies water first.

Can I set my unit for the whole night, should I have any safety concerns?

This depends on the time of the year, but generally, it is never going to be such dry to require your device to keep going deep in the night – it’s usually humid. Your safety will be always secured because these units are user-friendly.

They are designed to be used in bedrooms (of course other spaces too), the key is they are human-oriented. They improve sleep, contribute to softer skin, and can even speed up your healing process if you are sick.

Can I use tap water in my filterless humidifier?

Yes, although tap water contains more contaminants and minerals. With continuous use, these can form solid deposits in your humidifier, reducing its efficiency. This will put you to the task of regularly cleaning your device (not bad anyway, ha!). But seriously, it’s good to use distilled water all the time – as recommended by experts.

How often should I change the water in the humidifier?

Well, make sure you change the water before each use, and if there is still some water in the reservoir, you may opt to empty and change or leave it to be completely used, then refill with clean water. Just make sure that with every single refill you wash the tank and add new clean water to it.
