Who Should Buy a Humidifier

There are several reasons to purchase a humidifier, but one of the most common is to ease congestion caused by colds and allergies. If you frequently suffer from dry sinuses or even dry skin, a humidifier can create a cool mist that can keep your sinuses and skin hydrated. For more options to moisturize dry skin, check out our review of the best massage oils.

Low humidity is generally experienced in the winter months, although some climates tend to be drier throughout the year. Maintaining an ideal humidity range in your environment – whether it’s your bedroom, your family room, or your office – can improve your overall health.

The best way to measure the humidity in your home is by using a hygrometer. These can be purchased at your local hardware store – or you can consider buying a humidifier with a built-in humidistat so you always know the level of humidity inside your home.

When purchasing a humidifier, consider the room or area you want to use it in and choose a humidifier that can accommodate the square footage of the space. Buying a humidifier that is too large for the space can cause excess moisture, which can lead to mold and mildew. Bacteria and mold can also grow inside your humidifier if it’s not cleaned properly. Choosing a humidifier that provides warm mist can minimize the bacteria that form inside the humidifier. Be sure to maintain your humidifier regularly to avoid potential issues.

Important Features to Consider

A humidifier should be able to provide you with sufficient mist to alleviate the symptoms of a cold or allergies. Here’s what to consider when selecting a humidifier:

  • Capacity. Before purchasing a humidifier, consider the size of the room in which the unit will be placed. If the unit is too small, it will not properly humidify the room. Too large, and it could cause condensation or mold issues from too much moisture.
  • Filter requirements. Some humidifiers require you to change a filter after several uses. Other humidifiers are filter-less, so there are no costly filter replacements to buy. However, you should still maintain these units properly, including cleaning them regularly.
  • Mist options. Some humidifiers offer only cool mist, while others offer both cool and warm mist. A cool mist is more beneficial for soothing cold and sinus symptoms. A warm mist is healthier overall since the water heats to a temperature that kills bacteria and mold that can form inside the humidifier.
  • Warranty. All humidifiers carry different warranties, generally from 30 days to 2 years. Researching the warranty details can help protect your initial investment.

Frequently Asked Questions

What is a humidifier and how does it work?

A humidifier works by adding moisture to dry air by using an invisible mist. Different types of humidifiers include evaporative, ultrasonic, cool mist, and warm mist. The humidity of your home should always be in the 40-60% range.

Humidifying the air is also beneficial for your overall health. It is also crucial for keeping your home balanced by providing moisture for wood floors and cabinets and even preventing static electricity.

Is it good to sleep with a humidifier?

Certain climates tend to have dry air year-round, while most climates require humidifiers only in the winter. Humidifiers are useful for alleviating congestion from colds and can aid in suppressing symptoms for respiratory illnesses.

How often should you clean your humidifier?

It is recommended that you clean your humidifier every few days. Use a soft brush and a mild soap to wipe away any debris or buildup. Rinse the humidifier to remove any residue and wait for it to dry completely before refilling with fresh water. You can also use a damp cloth to clean the exterior of the humidifier as it will gather dust and dirt over time.

Which is better cool or warm mist humidifier?

Warm-mist and cool-mist humidifiers are equal when it comes to adding moisture to the air. If you are using a humidifier in a child’s room, cool-mist humidifiers are typically recommended for safety.
