With exact dimensions of 15.5 x 24.5 x 3.75 inches, this SlimFit design is tailored for 4-inch systems while delivering cleaner, more breathable air in daily life.

Why it stands out

  • High filtration efficiency targets small particles and general household debris.
  • Large particles like lint, pollen, and dust are captured to help keep surfaces cleaner.
  • Certified asthma and allergy-friendly, supporting a thoughtful approach to indoor air care.

Real-life benefits

In homes with pets, exposure to smoke or smog, and seasonal allergens, this filter supports a perception of cleaner air in living spaces. Users may notice smoother airflow as the filter operates, contributing to a more comfortable home environment.

  • Pet dander, smoke-related particles, and general allergens are addressed as air moves through the filter.
  • Regular filtration can help reduce visible dust buildup between cleaning tasks.

  • Replace the filter at least once per year for optimal performance in 4-inch systems.
