Meet the PuroAir MegaFilter

The PuroAir MegaFilter is engineered for 20x20x1 HVAC slots, delivering a precise fit with an actual size of 19.75" x 19.75" x 0.75". It installs quickly in most furnaces and air conditioners, typically in about 30 seconds, so you can refresh your indoor air without a long interruption to your day.

Three-layer filtration designed for real-life spaces

The MegaFilter uses a robust three-layer system to tackle everyday indoor particles. A prefilter catches larger debris, a MERV 13 main layer handles finer dust and pollen, and CarbonTech activated carbon targets odors. This combination aims to keep living rooms, bedrooms, and shared spaces feeling fresher overall.

  • Three-stage design targets common household irritants like pollen, dust, and pet dander.
  • Activated carbon helps reduce everyday odors from cooking, smoke, and everyday activity.

Performance you can notice, not promise guarantees

Independent lab testing suggests improved filtration efficiency for particles in the 1–3 micron range when paired with typical MERV 13 and carbon filtration. The design is described as 4X stronger than some lower-grade filters, though results can vary by system and environment.

  • Enhanced filtration compared with basic fiberglass options under lab conditions.
  • CarbonTech layer helps address odor molecules for a fresher indoor feel.

Long-lasting value and convenience

Built for durability, these filters are designed to extend intervals between replacements, delivering steady filtration performance over time. The 4-pack format keeps you stocked, helping simplify maintenance when schedules get busy.

  • Longer-lasting filtration than traditional fiberglass alternatives in typical use.
  • 4-pack provides a ready-to-change supply to reduce shopping trips.

What this could mean for your space

In everyday life, you may notice a sense of cleaner air and more consistent HVAC performance. While individual results vary, a system using these filters can contribute to a drier, more neutral indoor odor profile and a steadier airflow throughout the home.
