PuroAir MegaFilter 20x20x1 – MERV 13 + Activated Carbon HVAC Filter (2-Pack)

Upgrade Your Indoor Air with PuroAir MegaFilter 20x20x1

Designed for tight spaces and busy homes, the PuroAir MegaFilter blends a robust 3-layer filtration system with Activated CarbonTech to help reduce common indoor pollutants. It fits standard 20x20x1 HVAC openings with an actual size of 19.75 by 19.75 by 0.75 inches, making installation quick and straightforward in most air conditioners and furnaces.

What sets this filter apart is its layered approach: a durable prefilter protects the core, a MERV 13 filter captures fine particles, and the CarbonTech activated carbon layer targets odors and volatile compounds. In independent testing, this combination efficiently filters fine particles in the 1 to 3 micron range and blocks particles far smaller than a human hair. Real-world results can vary, but many users notice crisper air and less lingering dust over time.

Fast, simple installation is a hallmark. The MegaFilter slides into place in about 30 seconds, and the filter is designed to stay in place in most 20x20x1 systems. Built to last longer than typical fiberglass filters, it aims to reduce the frequency of replacements while keeping filtration performance steady across the season.
