Frequently Asked Questions
Q: How often do I need to change my air purifier filter?
A: Most True HEPA filters need replacement every 6 to 12 months, depending on your air quality and usage. Always check the manufacturer’s guidelines for your specific model.
Q: Do I need a whole house air purifier for every room?
A: Not necessarily. A high-capacity air purifier designed for large areas can often handle open floor plans. However, for smaller, closed-off bedrooms, a separate unit or a portable purifier is usually better.
