With both online and in-store shopping, Walmart is a convenient and often affordable place to shop. In this guide, we’ll dive into the function of a humidifier and provide you with our top five picks for Walmart humidifier options and our top pick from Amazon.

Humidifiers come in all sizes and utilize various technologies to increase indoor humidity. You can choose from warm mist or cool mist models and some incorporate additional features such as essential oil diffusion. When it comes to shopping for humidifiers, Walmart is a great place to start.

Low indoor humidity can make your throat scratchy and dry and may also exacerbate other respiratory conditions like allergies and asthma. If you experience frequent bloody noses, chapped lips, or colds and flu, a humidifier might be able to help. 

What Does a Humidifier Do? 

As you might imagine from the name, a humidifier is a device that humidifies the room. These are small, portable devices that often sit on top of a table or counter and help increase humidity levels in the room in which they are placed. They draw water from a storage tank and then release it into the air in the form of vapor or steam.

There are two primary categories of humidifiers: warm mist and cool mist. Cool mist humidifiers are safe for all applications but warm mist humidifiers use a heating element which may pose some degree of danger for children and pets. However, warm mist humidifiers have the added benefit of killing bacteria and germs because they boil the water before then releasing it.

Cool mist humidifiers come in several forms, the most common of which are evaporative and ultrasonic. An evaporative humidifier utilizes a moisture-wicking filter and a fan. The filter draws in moisture and the fan blows air over it, turning the water into tiny droplets that are then dispersed into the air. Ultrasonic humidifiers use high-frequency technology to create and release a fine mist.

By increasing indoor humidity levels, humidifiers can help reduce symptoms of asthma and allergies, relieve issues with dry skin, and may keep you from getting sick as often. Most humidifiers allow you to choose from multiple settings to customize the mist output. Some even automate the entire process, measuring your indoor humidity and adjusting accordingly.

Is a Humidifier Right for You? 

Before you go shopping for a humidifier, ask yourself if you really need one. It’s wise to first measure your indoor humidity levels using a hygrometer to determine if it’s necessary. A hygrometer is an inexpensive device that measures moisture levels in the air. Humidity somewhere between 30% and 50% is ideal for the home.

If you find that your humidity level is actually too high, a dehumidifier might be a more appropriate choice. These devices work opposite of humidifiers – they remove moisture from the air. A dehumidifier can help prevent damage to flooring and furniture caused by high humidity levels and may help reduce symptoms of asthma and allergies. 

After determining that your indoor humidity level is too low, you can start to shop around for a humidifier. Walmart is a great place to start, but you’ll find plenty of options elsewhere online. Check out our in-depth review of one of the top humidifiers on the market, the Veva Humidifier.

Bottom Line

Every home is different and indoor humidity levels can be affected by the climate in which you live. Hot and moist climates are more likely to have indoor humidity because the air holds more moisture at high temperatures. If you live in a colder climate, you’re more likely to experience issues with low humidity and might benefit from a humidifier.
