The answer to 'should I get humidifier or' is that it depends on your specific needs and home environment. A humidifier can provide several benefits, such as reducing dry air, relieving respiratory symptoms, and protecting wood furniture. However, a dehumidifier may be more appropriate if you have issues with excess moisture or mold.
Factors to consider include the climate you live in, any existing moisture problems in your home, and whether you or your family members have respiratory conditions that could be improved with better humidity control. It's also important to choose the right size and type of humidifier or dehumidifier for your home's square footage.
