What You Need to Know About Humidity

Indoor humidity levels affect floor, walls, and furniture. What is more, it has a great impact on human’s health. For instance, excessive moisture may cause allergic rhinitis or even asthma. On the other hand, if the air in your room is too dry, you may end up with sinus trouble. Lack of humidity weakens an immune system, causes fatigue and grittiness. Too low or too high humidity is harmful to kids, especially newborn babies. That is why it is essential to monitor humidity levels, especially if you have children. Indoor humidity depends on many things such as weather and climate conditions, as well as the use of various household appliances. A hygrometer allows controlling indoor humidity level to preserve your health and valuables.

More Than You've Expected

No matter how many mobile devices you have at home, they all can be used to monitor the measurements as long as you download the app. Moreover, if you have several sensors, a single gadget will allow you to monitor them all. If you are away, the device will save data for the last 20 days for your reference. Moreover, there is even an option to monitor the parameters from any part of the world provided you have access to the Internet.

Though the SensorPush hygrometer was designed for indoor use, it can come in handy for measuring outdoor temperature and humidity, just make sure it is protected from the elements (the unit is not waterproof).

To sum up, this professional humidity monitor is the perfect choice for those who appreciate advanced technologies and take care of their health.

Know Your Home Humidity

Some of us tend to forget about the importance of the indoor climate. Humidity matters just as much as the home temperature levels, and certain household objects or wines can even be damaged if the numbers go off. The Govee humidity monitor is always there to tell you if everything is up to the standards – and beneficial to your health.

Let’s start with the comfort level indicator that shows if the indoor conditions are comfortable or uncomfortable. This is important for preventing such health issues as colds, asthma, or allergies. If the readings get off normal, you’ll know about that first-hand and be able to adjust the settings for humidifier, dehumidifier, heater, AC, and more.

This humidity monitor can be easily checked via the Govee Home App within the Bluetooth range of up to 262 ft. While the app doesn’t have a Wi-Fi version, it gives you all the necessary info in just a few taps. The 20-day stored data is always at your disposal, and the handy alerts will notify you if the readings exceed the preset limits. This way, you’ll know immediately if something changes in the home microclimate and there is a need for action.

Upscale Accuracy

Is this humidity monitor accurate? Actually, a lot. With the temp range of ±0.54 °F and the ±3%RH for humidity, you’ll be impressed at how amazingly it works. At last, no second-guessing or suspecting your monitor of misinforming you. Enjoy some of the most accurate data you’ll get from a device in this class.

As for the design, the Govee will surprise you with how user-friendly it actually is. It’s compact but easy to read with big and clear digits. Use it anywhere around the house, from the cellar to the baby room. Just one glance at the monochrome display – and you’ll know all about the indoor temp and humidity.

Great news for sustainable households; this humidity monitor doesn’t consume a lot of power, and you’ll only need to replace the batteries once in 3-4 months. Yes, it’s a bit hard to open up for a change, but not impossible. In the end, your bills won’t suffer from yet another smart device, and you’ll happily save up in case your heating/cooling system turns out to be somewhat off.

In conclusion, the accuracy and usability of this humidity monitor makes it a welcome buy for any modern home.

Your Perfect Microclimate

The indoor microclimate can change for better – or for worse – without you even noticing it. The ThermoPro TP50 digital hygrometer will make sure that this won’t happen in your case.

To start with, this practical hygrometer has an air comfort indicator with the 3 conditions (Dry, Comfort, Wet) to let you know what really happens at your place. Additionally, each of them has a simple face icon to be recognized immediately. The monochrome display comes with the big easy-to-view digits, so you won’t have to come face to face with the device for reading it.

Regarding the accuracy, the ThermoPro measures on the professional level with ±1°F and ±2~3%RH for the temperature and humidity respectively. However, the comfort zone indicator range may not be one hundred percent accurate at all times. When in doubt, check the readings against what is considered “dry” or “wet” in your home region.

This hygrometer updates every 10 seconds for your ultimate comfort. You can get the exact readings practically anytime – and adjust your AC, heater, or humidifier to save the day without delay.

Compact & Handy

The ThermoPro is one portable hygrometer, measuring 3.11 x 0.84 x 2.62 inches. You can use a handy stand to put it on tables or cabinets (just like an alarm clock). Alternatively, stick it on your fridge with a magnet and let it sit beside your shopping lists and notes. The choice is all up to you thanks to the user-focused design.

Great, but do you really need a humidity monitor at home? The correct answer would be “yes” if you do care about your health and wellbeing. If the humidity (or temp) is wrong, this can lead to colds, allergies, and other conditions.

You can also use this device to keep track of your fridge, soil, or pet reptiles. The more versatility, the better, as you don’t need to buy 100+ more gadgets to keep an eye on everything at home. The ThermoPro keeps the history of high and low readings for the stats.

The power source for this hygrometer is a single AAA battery that’s included in the package. No need to change the battery too often, which is good for the nature – and your wallet, of course.

All in all, this practical device will be your watchful eye at home – and give you the exact humidity and temperature at almost any moment.

Large Easy-to-read Display

One of the things most people don't like about hygrometers is that they are usually very small and have cramped LCD screens that are hard to read. However, the AcuRite humidity monitor is different.

The standout of this model is its large 2.4" х 3.1" LCD screen, which makes it easy to read not only the current measurements but also the max/min data for a day. Aside from the basic data, it has a humidity level icon, telling you when the humidity level is good, low or high. The readings are displayed in the bold font and are large enough to easily read them at a distance.

Another advantage of the model is that it can be placed just about anywhere, be it your office desk or bedside table, thanks to the fold-out stand. Moreover, it has an ergonomic magnetic backing, making it possible to hang it on the door of your refridgerator, the reptile tank, and more.

The device is powered by a single AA battery. However, take note that it's not included with the purchase and you need to buy it separately to start using the device after unpacking.

How to Reduce Home Humidity

If the air in the room is too dry, it needs to be humidified. High humidity is bad for your health and detrimental for your home. Too much moisture in the air can be caused by climate/weather conditions or geographic location, such as ponds near houses or a lot of water underground. 

If the problem is the location, you need to optimize the humidity level in the room. The first thing you can do is heat and ventilate your home. This method can help in cool weather. The most convenient way to normalize humidity levels is to use a specially designed device called a dehumidifier. It will help remove excess moisture from the air. In addition to providing the perfect humidity level, these high-quality up-to-date devices will purify the air, which is very important for human health.

Get Accurate Readings

Neat and accurate, this digital hygrometer is very simple in use. Just open the battery compartment, insert the battery, and replace the cover. Then, choose the temperature units - Fahrenheit (ºF) or Celsius (ºC) using the switch on the unit's back. Place the unit out of direct sunlight and away from heat or humidity sources and vents to get the most accurate measurements.

Small & Handy

Actually, there is no need to overpay for a hygrometer. You can have a highly accurate one for much less if you get the Goabroa mini humidity monitor. Let’s take a good look at this handy portable device.

First of all, where do you use it? Thanks to the size of 1.89 x 1.13 x 0.66 inches, it can be placed just about anywhere, from a guitar case to a reptile tank or incubator. The hygrometer is as small as it gets, which is a huge advantage besides the economical price. Keep an eye on your pet lizard’s habitat – or help the eggs hatch with the right microclimate.

The Goabroa gives you fresh readings every 10 seconds for more comfort. The built-in sensor provides accurate – if not 100% precise – humidity and temperature. If there is a discrepancy, it’s not excessive by any means. However, you’re welcome to try the good old salt and water test to read the difference. This device is not a pro tool, but then, it doesn’t cost like one.

As for the range, you’ll get -58 °F ~ 158 °F (temp) and 10% RH ~ 95% RH (humidity). Just fine for home use and keeping it all at the right level for your and family’s wellbeing.

Read It at a Glance

Although small, this hygrometer is equipped with a readable LCD screen. The main digits are big enough to not overstrain your eyes, and all the info can be viewed at a glance. Just what you need for checking how your reptile pets, cigars, or wine bottles are doing. If you don’t want the overloaded “stations” – just a basic unit – then look no further than the Goabroa.

Another pro of this device is that it comes with a durable LR44 battery that is included in the package. You won’t have to change it for as long as 18-24 months – and when you have to, simply order a replacement; this battery type is pretty common and nothing out of the way. The battery compartment is a bit too easy to open, although this really is a minor issue. The important thing is that you can use the hygrometer straight outside the box.

What could actually be improved is the absence of instructions or a manual. Hey, Goabroa, you can do better and include them even if the unit seems as simple as the ABC.

To sum up, this mini humidity monitor is just what it says on the tin: a very compact and highly precise device to keep track of your domestic microclimate.

What Is a Hygrometer?

At all times, health comes first. However, it can be easily affected by external factors, such as living conditions in which we live. Humidity is one of them. If it's too high, it can cause your heart to beat faster, resulting in hyperthemia, and when it's too low, it can cause dry eyes, blocked nose, chronic fatigie and dehydration. That's why it's important to keep it balanced, and this is where a hygrometer comes to your help. Now, let's take a look at the benefits of having a hygrometer.

First of all, it contributes to the well-being of your family by keeping you informed of the humidity level in your dwelling so you know if it deviates from the norm and can do adjustments. And secondly, it helps prevent damage to the property, wall art, fine wines, and luxury cigars, eliminating the risk of mold and decay earlier than the time comes.

To help you pick the right product, we've narrowed down the choice of options available to the top 5. Take a look and make up your mind.

If you need a device displaying a broader spectrum of measurements, you may want to have a look at our best weather stations review. Another appliance that may help with maintaining the optimal temperature in your room is a portable air conditioner.

What Features to Compare

Use

The first thing to consider while selecting a humidity monitor is its scope of application. In our five best hygrometer review, you will find middle-sized models designed for home and office use. There are also efficient portable devices designed to monitor dampness in cigar humidors and wine cellars in order to preserve the high quality of these fine goods. In addition to an RH (relative humidity) index, digital hygrometers usually display temperature. Some multifunctional devices also display time and date.

Next, there are hygrometers specifically designed for indoor and/or for outdoor use. Some indoor models can be used with outdoor remote sensors. There are even sophisticated models that work as remote sensors sending the measurements to your mobile device via Bluetooth or the Internet. In other words, these smart hygrometers will allow you to monitor an RH index and indoor temperature and will display them on your gadget's screen even when you are not at home. You should keep in mind that most hygrometers on the market are not waterproof, which means they will show accurate readings only if you place them in a protected area. Please, always carefully follow the manufacturer's instructions to ensure a long service life of the tool.

Measurements

The next tip is a measuring range. Some cutting-edge devices allow monitoring the RH index starting from 0% up to 100%. However, for everyday home use, a model with 20%-90% range is quite enough (the normal humidity index is 45%-55%). One more important characteristic is the device's max/min temperature acceptable for its proper operation. Most indoor thermometer hygrometers work within the range of 32ºF to 122ºF (0ºC to 50ºC). If you are looking a unit to obtain measurements outdoors, make sure it has a wider temperature and humidity range appropriate for your climate.

One more thing to consider is the measurements accuracy, which depends on more than just your chosen model. The readings might be less accurate if the RH index gets too high. Generally, a ±2% increment (±3% under high humidity conditions) is quite common.

Extras

Selecting the humidity meter, keep in mind its additional features. Choose a model with min/max data saving option and you will be able to monitor dampness during the whole day, or even a longer period of time if needed. A large LCD display is easy to read, especially if it is backlit, it is clearly seen even in a dark room. If you own a big house, consider getting the device with remote sensors for monitoring both indoor and outdoor areas, such as you cellar, porch, garage, greenhouse, yard, etc.

Do not forget about the convenience of use! Humidity monitors usually have foldout stands for placing them on a shelf and holes for hanging them on a wall and/or magnetic backings perfect for mounting on a metal surface. Most electronic hygrometers are battery-powered; some models come with a battery included so you can use them right of the box. Easy-to-follow user instructions will help you in setting up the hygrometer and calibrating it.
