Best Hygrometer

While often going unnoticed to most people, the humidity level of any given room has the potential to affect your overall health. From affecting the quality of your skin if humidity is too low to even making it more comfortable to breathe thereby increasing the likelihood of suffering from allergies to even fostering the growth of fungal outbreaks in the form of mold to causing asthma attacks, humidity should always be something that is constantly monitored.

Even when it comes to preserving your precious cases of wine, valuable books, and dry-aged meats, humidity has the potential to either spoil or enhance. 

To help you keep tabs on your surrounding’s overall humidity levels – be it at home or anywhere else – hygrometers will be your best friend. Used by meteorological scientists and the general public for centuries, they are able to accurately measure the humidity of any given room. So, to help you navigate your way through the market of hygrometers, check out our take on the best hygrometers you can get right now.

A Buyer’s Guide to Hygrometers


Much like a ruler, there’s no point in measuring anything if what you use produces incorrect results. Every option we’ve reviewed is extremely reliable and will suit the average user, but you should always ask yourself how much precision matters to you. If you’re looking for something for your household, garden, or office, anything that has a margin of error of roughly +-1% RH should be okay but if you’re a budding scientist looking for cutting-edge precision, we suggest you look elsewhere.


Powering your hygrometer and ensuring it’s constantly working is essential when it comes to getting the most accurate result possible. If you’re opting for a digital device, ensure you have a set of batteries constantly ready for when the juice runs low. If you’re using a mechanical hygrometer though, you can virtually ignore this point.


The best hygrometers for home use is one that is totally unnoticeable and unobtrusive. You don’t want to have some unwieldy and ugly device clogging up your rooms after all! While balancing compactness and accuracy is an entirely separate debate, the average user will not have to worry about comprising one or the other in the vast majority of cases.

Just don’t forget to check the size of your intended device and use it before purchasing – the last thing you want is for your hygrometer to be entirely inappropriate (e.g. using it in a tiny music case or meat box).


Frequently Asked Questions (FAQs)

How does a hygrometer work?

It’s essentially a measuring device that keeps track of the humidity level of any given environment. It does this by measuring the amount of moisture in an area and calculates it as relative humidity, which is basically the quantity of water in relation to the highest temperature at present expressed as a percentage.

Another less common measurement some hygrometers calculate is specific humidity which is instead the amount of water vapor in any given kilogram of air.

You won’t find this in any of the products we’ve reviewed though if that matters. So naturally, if you were walking through the Sahara, your hygrometer will present extremely low readings. Conversely, sailing through the ocean or walking through rain will do the exact opposite. 


What is the danger of having too much humidity?

Too much humidity is often a problem that arises when summer comes. You’ll find excessive condensation building up on windows and more damp spots around your house which will lead to mold and fungi buildups if left unchecked. This in turn can aggravate respiratory problems like asthma and even allergies.


What is the danger of having too low humidity? 

Unfortunately, the flip side of too much humidity also presents a serious problem. You’ll find your wood-based furniture warping and shrinking, your painted walls starting to peel, and even the air feeling uncomfortable to breathe. You’ll also notice cracking skin on your lips, itchy throats, and even more serious health problems such as bleeding nostrils and colds.

Deadly microbes like viruses absolutely love low humidity environments and will affect you not addressed.
