Fully tested by an independent ISO Certified Lab in Canada. The HempGuard achieved a rating of MERV 8 (Minimum Efficiency Reporting Value), which is the new standard for residential HVAC filters. The HempGuard can filter down to 0.5 microns, effective for Pet Dander, Pollen, Mold, Smoke, Odor, Bacteria, and Dust.
The HempGuard lasts up to 6 months (100%) longer than any other allergen filter on the market) and can be cleaned periodically to improve pressure drop, thereby saving energy and wear-and-tear on your HVAC unit.
It is perfect for every home and office!
