Humidifiers For Allergies Buyer’s Guide

There are certain times of the year where breathing becomes more of a challenge, but there are products like humidifiers for allergies that can help the user get a peaceful night’s sleep. This is only the case when pursuing the right product and from a reputable brand. This is no easy feat as the market is flooded with products claiming to provide the best results.

To help make it easier to differentiate the ones that can help clear allergies as they can keep humidity at around 40%, and those that will be ineffective, we have created the following buyer’s guide.

What To Look For In a Humidifier For Allergies

Tank Capacity

Usually, it is a case of the bigger the tank, the longer the humidifier can stay on throughout the night. This is important as the more relief from allergies the humidifier can provide, the better. This can also help to clear sinuses which is a common issue for those with allergies so anything around 6 liters and above is going to go a long way towards making the nights more comfortable. 

Quiet Operation

Whether the intention is to use the device in the office throughout the day or in the bedroom at night, it still needs to be quiet. Most brands ensure theirs are ‘whisper quiet’ and although this term gets banded around a lot, it is a good indication as to how easy it is going to be on the ears.

Programmable Cycles

Being able to tailor the experience when using a humidifier for allergies is important as using it for too long could be detrimental. This is why intermittent cycles and strength of the output are all going to help. This can also extend the time it can be used throughout the night.

Easy To Clean

Anyone with allergies will know that hygiene is important for helping clear up sinuses and getting rid of a cough or dry throat. Because of this, it is important to clean the humidifier regularly. The easier the tank is to remove, and the filters to change, the better.


Coverage Anyone with a large bedroom will need a more powerful product that has the coverage to reach the stretch of the room. Before purchasing, ensure you know the meters squared of the room you intend to use it in so you can find a suitable product. 


Features like auto shut off are important, especially when dealing with the combination of water and electricity. Most reputable brands ensure this is in place as standard, with some going even further.

How Often Should I Use A Humidifier For Allergies?

The trick is to not overdo things, so you don’t want the humidifier running 24/7. A room that is too humid can harm health and allergies. A lot of experts say that humidity shouldn’t exceed 50% when indoors. It is best to find a product where you can program the humidity levels so that it never becomes too damp in the room which can cause breathing difficulties as well as mold. 

Are Humidifiers Good For Allergies?

Because they add moisture to the dry air which is known to carry allergens among other things, humidifiers are beneficial when used correctly. It is important to remember to clean them properly and regularly so they are always pushing out the clean mist. The fewer allergens there are in the air, the better it is for the sinuses and the less inflammation there will be.

Will a Humidifier Help Sinuses?

The consensus is that pushing more humidity into the air can help. They unblock the sinuses by creating more moisture which makes breathing easier and the nights a lot more comfortable.

How Much Does A Humidifier Cost?

It is difficult to put a price on a good night’s sleep, so if a humidifier helps to clear sinuses and alleviate some of the symptoms of allergies, then it is a worthy purchase. Most reputable brands tend to start at around $40 but can be well over triple that amount for something with a larger tank, wider coverage, and added features. 

What Is The Best Humidifier For Allergies?

After considering numerous products, we found the best to be the TaoTronics Cool Mist Humidifier. With its wider coverage of 30 meters squared, it can be used in most average-sized rooms and is quieter at most when in operation due to its 38 dB noise output. Also, it can be used up to 30 hours meaning it is great for helping with allergies and leaving it to work its magic.
