Product Description

Say goodbye to allergies and hello to clean air with the revolutionary PuroAir HVAC Mega Air Filter! Our high-performance carbon-activated filter is the ultimate solution for improving air quality in both residential and commercial HVAC systems. By harnessing the power of activated carbon, these MERV 13 filters reduce a wide range of pollutants that traditional fiberglass HVAC filters can't capture, including allergens4, harmful gases, odors1, volatile organic compounds (VOCs5), and other airborne particles.7 The cutting-edge technology behind carbon filtration ensures a cleaner, fresher, and healthier indoor environment, making it the perfect choice for any space where air quality matters.

Looking to take your clean air to the next level? Create the ultimate clean air environment in your home or office by combining the power of Mega HVAC Filters and the air cleaning technology of PuroAir Air Purifiers. With this whole home system, you and your loved ones will breathe easier than ever before.

Benefits of the PuroAir HVAC Mega Filter

Activated Carbon Layer: The heart of the filter is its activated carbon material, which has a highly porous surface that purifies odors1 and gases. This makes it an effective barrier against smoke4, cooking odors1, pet smells, and other household or environmental pollutants.

MERV 13 Layer: The MERV 13 rated filter layer blocks fine air particles down to 1 micron7.

Pre-filter Layer: Filters larger visible air pollutants like dust3, pollen4, pet hair, and more.

Volatile Organic Compounds (VOCs5): Activated carbon is particularly adept at adsorbing VOCs5, which are chemicals emitted from paints, cleaning supplies, and other household products.5 Reducing VOCs5 helps create a healthier indoor air environment by minimizing exposure to potentially harmful substances.

Odor: One of the most notable benefits of carbon-activated PuroAir Mega HVAC Filters is their ability to reduce stubborn odors1, such as those caused by cooking, pet dander4, mold4, and smoke4. This can significantly improve the comfort and freshness of indoor spaces.7

Ideal for Sensitive Environments: These home air filters are ideal for households with allergy sufferers, asthma patients, or individuals sensitive to air quality. They are also highly effective in environments like offices, and restaurants, where air purity is essential.

Quiet Operation: Carbon-activated filters do not disrupt HVAC system operation. Their design allows for smooth airflow, maintaining optimal air circulation without adding noise or strain to the system.7

Easy Installation and Maintenance: Carbon-activated HVAC filters are typically designed to fit most standard HVAC units. They are easy to install and replace, making them a convenient option for improving indoor air quality without major modifications to your existing system.

Features:

  • MERV Rating 13
  • Pleated filter to mitigate more particles6
  • Lasts 3x longer than fiberglass filters6
  • Ideal AC filter for people with allergies or respiratory issues7

REPLACING YOUR FILTER

We recommend replacing your air filter every 3 months or 90 days.  Due to build-up of captured air pollutants, waiting longer than 90 days could decrease the effectiveness of your air filter.  During periods of poor air quality due to increased allergens, wildfire smoke, renovation projects, etc. we recommend replacing the filter sooner.
