What is HEPA Filtration?
HEPA filtration is a method of air purification that captures at least 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, and volatile organic compounds.
These filters force air through a fine mesh that traps these tiny particles, ensuring significantly cleaner air.
Unlike standard 1-inch pre-filters that primarily block larger particles and require replacement every three months, HEPA filters offer more effective and efficient filtration and only need to be changed every six to 12 months.
On the other hand, UV lights are designed to kill bacteria and viruses by exposing them to ultraviolet light, but they do not remove particulate matter from the air.
HEPA filters provide a comprehensive solution and work best alongside pre-filters and/or ultraviolet lights.

People You Can Count On!
Are Portable or Whole-Home Air Purifiers Better?
Portable air purifiers are convenient devices designed to improve air quality in a single room or small area. They offer effective but limited coverage and require multiple units to purify the entire home.
Whole-home air purifiers are integrated into the HVAC system, ensuring clean air circulates throughout the living space. This comprehensive approach provides consistent air quality in every room, reduces the need for multiple devices, and is more efficient in maintaining a healthier indoor environment.
Whole-home air purifiers are the best solution for those seeking thorough and consistent air purification across their entire home.
