I f you care for your family’s health and your house, then you shouldn’t neglect humidity variations. Whether it is going up or down, it can do some serious damage. You could experience dry skin and itchy eyes, breathing problems, aggravated allergy attacks, or watch how your furniture begins to crack. In this case, the only solution is constant humidity monitoring.

The best indoor hygrometer will help you monitor the humidity level through accurate readings. All the units in our top have a thermometer function as well, designed to offer even more information about the environment in which you grow your plants, store your cigars, or pamper your reptile. Nevertheless, our ranking focused on their main function, so you can rest assured that no matter what device you choose, it will deliver only high-quality results.

What Is a Good Indoor Humidity Level?

Let’s start off with the definition of humidity. What is it exactly? Well, it’s the amount of moisture vapor the air contains. What is the right indoor humidity level? It should range from 30% to 50%. There is reasoning to these specific parameters – your health and even the structure of your home have to suffer if humidity is higher or lower than the recommended threshold.

  • Dangers of high indoor humidity: First off, there’s the issue of comfort. When humidity is high, your body won’t be able to regulate internal temperature properly. This results in the room feeling much hotter than it actually is. Considering that high humidity is usually an issue during the warm season, the feeling of discomfort is amplified greatly. Secondly, high air moisture spells trouble when it comes to your direct health because mold, fungus, and dust mites thrive in this sort of environment. For individuals who suffer from asthma or allergies, it’s a dangerous situation because the aforementioned air pollutants can trigger their symptoms and worsen their health issues. Third, the structure of your home can be compromised. Wood will rot with time, and insects will find their way inside. Furniture and other items can swell and warp, damaging beyond repair. The EPA offers some great tips on how to control moisture levels indoors when dealing with excess humidity, regardless of the problem’s source.
  • Dangers of low indoor humidity: Health-wise, dry air causes quite an alarming range of problems. Your skin starts to itch for one. Dry air also irritates the nose and causes breathing difficulties, making you cough and wheeze. You are more predisposed to catching colds when the air is too dry, which is worrying considering that this issue tends to appear during winter when the flu is already a circulating problem. When it comes to the well-being of your home, wood furniture, structures, and items are the ones to suffer once more. Wood warps and bends as it shrinks in size because of low moisture. If you have wooden floors, the planks will separate with time and start to creak more often. Woefully, low humidity even makes the room feel colder. Considering that it’s a problem typical for the cold season, you will end up abusing the heater just because humidity conditions don’t create a pleasant enough environment no matter how much you crank the heat up.

As you can see, there are serious repercussions related to both low and high humidity. Luckily, there are measures to combat both problems and keep a healthy indoor humidity level. However, the first step is always monitoring, and the best tool for this is the hygrometer. Stick with us, and you will learn what options you have and what makes these specific products better than their competition.

While solutions are plenty to fix low and high humidity issues, there are two products that are unbeatable when it comes to efficiency.

  • If you want to reduce humidity, a dehumidifier is your best ally. It works by pulling in air from the room, removing the moisture in it and trapping it in a special reservoir or directly draining it in a source of your choice, releasing dry air back into the room.
  • If you want to raise humidity, a humidifier is the way to go. While there are several types available according to their precise operating manner, what all of them have in common is their end goal – releasing moisture into the air to elevate humidity levels.

If you have a crawl space, it needs special attention. This is an oddly-sized area where high humidity is an inevitable issue, especially if you haven’t encapsulated the crawlway. A normal-size dehumidifier won’t fit here, and even if it does, it won’t work because of the harsh environmental conditions and very high moisture that it simply won’t manage to tame. What you need instead is a specialty crawl space dehumidifier that isn’t as tall as its regular counterpart, boasts a durable casing, can handle large spaces, and removes high amounts of humidity over a 24-hour period.

Super compact but featuring a solid structure, it is one of the most accurate and convenient on the market. The generous temperature and humidity ranges make it perfect for all types of environments, including basements, where high humidity can cause mold, storage areas, and laboratories. It is efficient in reading a humidity level between 10% and 99% and can measure temperatures between 14 and 140 degrees Fahrenheit. Moreover, it allows for measurement swap, so you can always change the temperature from Celsius to Fahrenheit.

Superior Accuracy

Some spaces need advanced temperature and humidity control. For example, the incubator might not deliver any chicken if the humidity isn’t high enough or your reptile pet might get sick if the humidity isn’t high enough. In this case, you will want to make sure everything is in order, and this device can help you do it due to the following features:

  • NIST certifiable - it shows that it complies with IOS and national-recognized accuracy standards
  • Strong RH accuracy - it can variate +/-4% between 25% and 85%
  • Temperature accuracy - at only ± 1.8° F, it has one of the most efficient temperature monitoring function in its class
  • Up to 2 measurements per second - this performance is difficult to overcome, as most models have a frequency of 1 measurement per 10 seconds or longer

The reduced dimensions make it portable. It measures only 4.3″ in height and has a footprint of 3.9″ x. 0.78″, so you will be able to maneuver it with ease, a function that will prove helpful if you are going to place it into a reptile tank or an incubator. Furthermore, as it comes with a stand and a bracket, you can choose either to place it on a table or shelf or hang it on the wall.

Premium Features

The solid structure is just one of the criteria that made us place it in the first position. We surely have appreciated the paint that makes the housing more durable and the high-quality materials that were used in its construction. Nonetheless, what impressed us the most was its versatility and convenience provided by a strong set of premium features:

  • Remote probe - makes the measuring even more accurate by extending the area 18 inches behind the walls
  • Audible alarm - activates when the minimum or maximum humidity value set by you is reached
  • Min/Max storing - the memory will store daily maximum and minimum values, for easier humidity tracking
  • Generous LCD screen - allows for simultaneous display of temperature, humidity, and dew point in large letters and numbers that can easily be read from the distance

The DEW point is a great addition that is rarely provided with a hygrometer. It represents a calculation of humidity and temperature that will allow you to know when condensation will happen. Thus, you can act against it by speeding up the dehumidifier, the air conditioning, or the fan and preventing mold from forming on your walls. For calibration, it features an adjustment pot and a reset function. Nevertheless, for field calibration, you will need to purchase the optional calibration kit. Besides that, with a 1-year warranty being offered by the manufacturing, you can put your mind at ease and test its accuracy.

If you’re interested in temperature readings instead and want a product that works both outside and in, we recommend that you get an indoor outdoor thermometer instead.

Extech Instruments Digit 445815 Performance Ratings – Tester’s Feedback
  • Humidity monitoring accuracy: Score – 10/10
  • Temperature monitoring accuracy: Score – 10/10
  • Ease of calibration: Score – 9.6/10
  • Ease of use: Score – 10/10
I did have a bit of trouble when first calibrating it, but I got the separate kit and the whole procedure went out easier after that point on. To check and see how accurate the Extech Instruments Digit 445815 is, I did the wet towel test. I just placed a damp towel over the instrument and waited 20 minutes on the clock. Then, I checked to see what humidity level the Extech showed, and it was on par with what it had to indicate – 99%. What I like most is that it shows the dew point since I got this nifty little device for my basement where I have condensation issues quite often and never seem to turn on the dehumidifier at the right time for it to pick up the excess moisture. I set the humidity threshold at 60%, and as soon as this level was reached, the hygrometer promptly sounded off the alarm to let me know. It’s very reliable and among the easiest to use, so even if you’re a first-timer, I’m positive your experience with the Extech will be just as pleasant as mine.

If you are willing to splurge, then you should go with a smart option, and this little hygrometer is just the best choice. Alternatively, if you want a second option with smartphone connectivity, you can look into the Govee Hygrometer Thermometer H5051 that is a bit cheaper than this SensorPush model. In fact, it consists of a tiny sensor that can be paired with your phone to deliver precise data on a range of up to 325 sq. ft. The sensor measures only 1.57″ in height and has a footprint of only 1.57″ per 0.65″, so it will fit in any tight space, no matter if we are talking about a cigar box, a reptile’s habitat, or an instrument case. It comes with a corner hole that allows you to hang it on the wall with the help of a lanyard. Furthermore, if you use it in a space that needs constant monitoring, you can purchase the optional G1 Wi-Fi Gateway, which looks like a miniature modem and helps connect the sensors to the internet so you can get real-time data from the distance. Additionally, if you wish to keep an eye on multiple spots in your house, you can invest in more sensors.

With a humidity range of 0% to 100%, you can rest assured that, no matter how close to the extreme the humidity will get, you will receive pertinent information, with an accuracy rate of 4.5% to 7.5%. Not as sharp as the first model, but still reliable, it measures the humidity once every minute. It can work in temperature conditions of -40F to 140F, with an accuracy of +/-0.5F to +/-0.9F, which is better. The overall performance is superior to most models, especially if we consider its ability to signal when the maximum or minimum humidity has been overreached. The signal isn’t audible. It is a notification that is pushed on your phone. Nonetheless, keep in mind that if you haven’t purchased the tiny modem and are not in the area, you will not receive the notification.

It records the extremes of every day and has enough capacity to store them for two days. The app provides access to graphics and tables that will show you the evolution of the parameters. It is easy to understand due to the straightforward categories. Besides that, you can rest assured that your cigars or iguana pet won’t remain unsupervised, not even a day, as the battery can last up to a year, so often replacements aren’t implied. The warranty is standard, with 1 year being offered for parts and labor.

  • Tiny and lightweight, easy to fit in narrow spaces
  • Smart sensor automatically sends data to the phone
  • Works in high-humidity environments
  • Accurate temperature measuring

If there’s a place in the house in need of a high-quality hygrometer, it is the basement. As it is placed underground and, thus, poorly ventilated, this space in the house is more prone to develop mold and bad odors. Moreover, the lighting is usually a problem in basements as no large windows are available to let the light in and, as no one is spending a lot of time there, the artificial lighting source is usually poor. In this case, the use of a device that can measure humidity with accuracy and display it on a large screen with tall characters is mandatory, and this model from ThermoPro meets all the requirements. If you want a cheaper alternative from the same manufacturer (ThermoPro is one of the finest brands on this market, we must specify), then look into the ThermoPro TP50 before you decide. It might be better suited for you.

First of all, the LCD screen of the TP55 is one of the largest you could find in these instruments and is backlit, so the information is available no matter if you place it in the darkest corner or try to read it with the light off. Nevertheless, despite the huge screen, the unit remains compact, measuring only 4.3 inches in height, 3.3 inches in width, and only 1 inch in depth.

In terms of accuracy, we have appreciated that it is one of the most precise in its class, as it offers an RH precision of 2% to 3% for a humidity range of 10% to 99%. The temperature readouts are reliable as well, as the maximum deviation doesn’t overcome +/-1 degree F. In this case, the measuring range is -4 to 158 F for indoor. Worthy to mention, it can be used for outdoor measurements as well. It collects new data every 10 secs and can be programmed to display temperature values either in Celsius or Fahrenheit. Plus, it stores minimums and maximums for every day, allowing you to keep track of the variations from the past days, and previsions the trend through arrows, allowing you to take measures before temperature or humidity reach critical values.

The touch screen is straightforward and allows for easy configuration. Besides that, it offers 3 mounting methods that make it highly versatile. Thus, you can place it on a shelf or a table, as it comes with a built-in stand, hang it on the wall, or stick it on the fridge, as it includes a magnet for this purpose. Not to mention that, in terms of warranty, this brand is super generous, offering 3 years for repairs and parts, and knowledgeable and friendly customer support for 5 days a week.

  • Large backlit touch screen is easy to read in the dark and user-friendly
  • Accurate readouts for both temperature and humidity
  • Three mounting methods
  • Excellent 3-year warranty
  • Trend arrows allow you to preconize dropouts or growths in humidity and temperature and make adjustments before critical values are reached

  • Although it is advertised as an indoor-outdoor unit, it is efficient only indoors
  • When the backlight is turned on, the temperature raises 3-4 degrees Fahrenheit


This is a solid model with plenty of options and comes at a great price, so it is totally worth the investment. The jumbo touch screen with the backlit option is a nice addition as it allows for distance reading. Plus, it can store min and max values for the previous days and uses arrows to indicate the trend for the following hours, so you will not have to wait for the parameters to reach critical values to adjust your appliances.

Grow rooms require constant monitoring, as the health of plants is directly dependent on environmental conditions. If the medium is too dry or too hot, the leaves can easily develop diseases linked to dehydration, while a high level of humidity can facilitate the growth of mold or cause the plants to rot. In this case, the most appropriate choice is a model that can stand the humidity conditions of a growth room while providing correct information. AcuRite 01083 can measure humidity values ranging from 1% to 99% with an accuracy of +/-2%, so we can easily place it among the most precise on the market. Moreover, it can collect data about the indoor temperature as well, with a span of -4 to 158 degrees F and precision of +/-0.5 degrees F. The measurements are made every 10 sec., so the results are always fresh from the field.

It features a large LCD, which is divided into two sections. On the top side, you will find the relative humidity value and the min and max of the day, while the bottom side shows the temperature and, once again, the minimums and maximums. It uses arrows to show the trends for both parameters. Plus the extremes of every day are stored, so you can get an accurate perspective on the parameter variations over time. In the middle of the screen, you will find a humidity level indicator, which uses 3 colors to indicate room conditions. Thus, if the blue LED is on, it means you will need to increase the moisture in the air. If the indicator is red, the moisture in the air is too high and your house is at risk of developing mold. Nevertheless, when the green light is on, it means everything is perfect and you can just enjoy your comfort.

Apart from the fact that it can be easily calibrated at home, as the instructions are clear and easy to follow, its popularity is increased by the three mounting alternatives. Thus, you can stick it on a fridge as it comes with a magnet, or mount it on the wall, as it offers this option. Additionally, you can place it on a table, as it includes a built-in stand. It is super compact, with a height of 3 inches, a width of 2.5 inches, and a depth of only 9 inches, so it won’t occupy too much space. The good news though is that the digital screen occupies most of it, so the characters are large, and you will be able to easily read them from the distance.

  • One of the most precise on the market
  • Can resist high humidity conditions
  • Large LCD screen allows for easy reading from the distance
  • Offers three mounting options
  • Easy to calibrate

  • Some customers complained that the backlight is rather dim
  • Calibration button is in the back, so it’s fairly inconvenient to access if you decide to mount the hygrometer

Produced by the same reliable manufacturer that brought us the impressive ThermoPro TP55, it is proof that you don’t need to spend a lot of money to get accurate readouts. In fact, if we look at its error range, we observed that the humidity may be off with 2% to 3% from the real value, while the temperature deviation won’t overcome +/-1 degree Celsius. It can work in any indoor environmental condition as the plastic housing make it resistant to wet spaces. Thus, it is an excellent choice for a wide spectrum of activities, including the growth of plants in a greenhouse, cigar collection, or the care for a reptile pet. It offers a broad array for humidity gauging, starting from 10% to 99%. Furthermore, it can display the values for temperatures spanning from -58 to 158 F, so you can count on it to provide correct information even if you use it in the basement.

Apart from the excellent accuracy features, which are compulsory in a great hygrometer, it features a practical design as well. Thus, the LCD occupies most of the space on the frontal side, so the characters are tall and easy to read. Along with the current RH and temperature values, which are refreshed every 10 seconds, the low and high values of the day are displayed. These can be stored as well for further analysis. Nevertheless, one of the most attractive features is the air comfort indicator, which uses face icons to show the comfort level. Thus, with a single look at the LCD, you can check if the air in your home is too humid, too dry, or just perfect.

With a height of 3.11 inches, a width of 2.62 inches, and a depth of 0.84 inches, it is portable and easy to carry around. Moreover, its versatility is increased by the two mounting options, which allow you either to stick it on a fridge or a metallic wall or place it on a tabletop, as it comes with a built-in stand. Regarding the warranty, we should mention that it covers parts and labor for a long period of 3 years, which, considering the price, is super generous. Nevertheless, you will have to register on the manufacturer’s website to get this offer. Otherwise, you will only get 1 year from the date of purchase.

Just like the EEEKit Hygrometer Thermometer Digital LCD Monitor, it includes multiple small-size hygrometers. To be specific, there are 4 tiny hygrometers ready to measure and display the relative humidity and temperature in the narrowest spaces in your house. Many customers have bought them for their reptile tank, as they are built of ABS and, hence, resistant to different environments. The small size of each unit is an essential factor as well, as it won’t cut too much into the space of the tank. Additionally, it is provided with an LCD screen that shows RH and temperature in large characters. The LCD measures 1.4 inches in width and 0.66 inches in height, while the whole device measures only 1.89 inches in width, 1.13 inches in height, and 0.6 inches in depth, so it is easy to figure out that the display occupies almost the entire surface.

Regarding the array of quantification, it is wide, varying from 10% to 99% for humidity and -58 to 158 degrees F for temperature. With an RH precision of +/-5% and a temperature precision of +/-2 degrees, it is suitable for home measurements, especially as the values are rechecked every 10s, so you will get real-time data that will help you to assess the situation on the spot and act immediately.

Regarding mounting options, it doesn’t come with a magnet or a stand, but it can be easily placed on a shelf, a table, in a cigar box, a reptile tank, a cellar, a closet, or wherever you need it most. Plus, as the set includes 4 pieces, you can get accurate data from different spots and determine if there’s a humidity problem in certain areas of your home. The temperature reading system can be easily switched from F to C and back. However, it doesn’t store lows and highs, so you won’t be able to get an overview of the measurements.

  • 4-piece package comes at a great price
  • Strong ABS housing makes it highly durable in harsh environments
  • Highly versatile due to the compact design that allows it to be placed in any space around the house
  • Great data update frequency
  • LCD screen is large enough for easy reading

  • The units are pre-calibrated and cannot be calibrated at home
  • Not suited for incubators


To summarize, the compactness of each unit makes this set perfect for multi-spot measuring. You can place one in your terrarium, one in your cigar box, one in your musical instrument case, and one in the greenhouse, and thus make sure each of your hobbies are under control. Besides that, the price is great and the measuring range is generous, so this is a clever investment.

Frequently Asked Questions

Where should I place the hygrometer?
There’s just one main rule you must abide by when it comes to placement, and that is to keep the humidity measuring tool away from the excess moisture that results from normal activities that unfold in the bathroom or kitchen. For short, if you keep the hygrometer say in the living room, home office, or bedroom, and you make sure that the doors to the kitchen and bathroom are closed during activities that amp moisture levels indoors, you can rely on the hygrometer to provide accurate readings related to living conditions.

Are home hygrometers accurate?
For the most part, hygrometers are very reliable instruments for humidity level readings. Most models are accurate within 5%, and we recommend that you check the specs provided by the manufacturer and go for a product that is within the 0% - 5% range. Just beware that accuracy mostly relies on calibration. A calibrated hygrometer is much more precise, so don’ neglect this procedure.

Which is better, an analog or digital hygrometer?
In theory, digital hygrometers are the superior option since their accuracy is said to be higher. However, at lower humidity levels, analog hygrometers have proven to be more accurate when it comes to the provided readings. Nevertheless, if you opt for a qualitative digital model like the products we reviewed previously, chances of any inaccuracy are slim, regardless of ambient conditions. There’s the added perk that digital instruments show the temperature too, so they come in handy in more ways than one.

How long does it take for a hygrometer to get an accurate reading?
The average time after you turn the digital hygrometer on until you can read the first reliable humidity stat it shows is approximately 3 minutes. It’s recommended that you place the instrument at least 3.3 feet above the ground to help it detect ambient humidity as accurately as possible.

How do I know if my hygrometer is working?
There’s a simple test that you can perform to check the tool’s accuracy. It consists of dampening a towel that you wrap around the hygrometer for about half an hour. If the tool is properly calibrated and works perfectly, it should show 100% humidity or the top humidity level that a specific model can display. If it’s not perfectly calibrated, the reading will likely be 10% to 20% lower than the peak level it can display.

How do you check humidity without a hygrometer?
Say that your hygrometer is temporarily unavailable for one reason or another. Or you’re away and you forgot the nifty tool at home, yet you want to check humidity as accurately as possible where you are at that moment. There best alternative methods include the wet and dry bulb and the ice cube method.

What is the best humidity level for sleeping?
The ideal level for sleeping is the same as it is generally, namely from 30% to 50%. While most studies agree with this threshold, there are other sources that recommend humidity from 40% to 60%. What is generally agreed upon is the peak threshold – moisture level indoors, regardless of whether it’s during sleep hours or normally, shouldn’t exceed 60%.

What humidity grows mold?
When humidity levels exceed 60%, the risk of mold growth appears. As the moisture level goes higher, the chances of mold growing raise too. In environments where humidity exceeds 80%, it is unlikely that mold hasn’t already settled in, for example.

What causes high humidity in a house?
There are several culprits for this issue. First, there’s a malfunctioning AC that doesn’t remove humidity as well as it should when it circulates the air in your home. Then, there’s a whole range of everyday activities you perform that amps moisture levels, including washing the dishes, cooking, bathing/showering, using the washing machine, and even sweating. Excess moisture also appears because of leaky pipes or cracked roof tiles. While less frequent, rising damp can be the source problem too. Moisture can rise from the ground through the masonry and brick pores.

How do I fix high humidity in my house?
Using a dehumidifier is the optimal solution to fix high humidity indoors. However, there are other viable fixes for this issue, namely:

  • Using the AC to expel the warm and humid air outside;
  • Turn on exhaust/ventilation fans whenever you cook and shower to expel the damp air ASAP;
  • Clean the gutters regularly and direct the downspout as far from your home as possible;
  • Keep the windows open as much as you can (this is recommended only if you don’t have an AC that would take care of taking the humid air out much more effectively);
  • Hang the clothes outside to dry instead of indoors whenever you can;
  • Relocate your plants in a room that is better ventilated;
  • Improvise a dehumidification tool by using charcoal briquettes that naturally absorb moisture;
  • Check if there are any leaky pipes around the house and fix them;
  • Take your showers as cold as you can.


No matter if you need to keep an eye on the humidity variations in your home and thus care for your family’s health or for specific activities that require accurate monitoring of the environmental parameters, an indoor hygrometer is always a great investment. As you have probably noticed, these devices are highly versatile and can easily match any space, but some are more accurate than others, while in some cases, the design adds value and makes the product more desirable.

Our ranking has focused on these 2 criteria while paying attention to the prices and warranty periods as well, so you can trust that the order reflects the quality of the products. Nevertheless, some models come with fewer functions but are more suitable for specific tasks, like monitoring a reptile tank or a box of cigars, so keep this in mind when making your decision.
