The answer to 'should I get humidifier or' is that it depends on your specific home environment and needs. Whole-home humidifiers and portable humidifiers both have their advantages and are useful for different situations.
Whole-home humidifiers integrate directly with your HVAC system and can automatically maintain optimal humidity levels throughout your entire house. They are more expensive to install but provide consistent, even humidity control. Portable humidifiers are less expensive and can be moved from room to room, but may require more manual adjustments. The right choice depends on the size of your home, your climate, and your desired level of humidity control.
