Greentech Ultra Shield™ - MERV 13 HVAC Filter with ODOGard®
Maximum protection—down to virus carriers.
This filter is like a fine-tuned sports car: precise, powerful, and not for everyone.
If you want the highest level of home air filtration, Ultra Shield™ delivers. This is our most advanced residential filter, capturing ultra-fine particles such as smoke, bacteria, and virus carriers—offering hospital-grade performance in a household setting. Combined with ODOGard®, it also neutralizes odors and harmful VOCs at the molecular level, giving you cleaner, fresher air with every breath.
Because of its dense filtration, Ultra Shield™ fills up faster than lower-rated filters. For optimal performance, it should be changed every 30 to 60 days. If regular filter changes aren’t realistic for your lifestyle, our Paws & Pollen™ (MERV 11) may be a better fit—it still provides excellent filtration with fewer replacements.

Higher MERV Rating, Lower Air Pressure.
Unlike high-efficiency filters that rely on temporary static charges to boost performance, our filters utilize cutting-edge advancements. We’ve perfected the science behind our filters by incorporating nanofiber with superior nonwoven material. This means we achieve the desired MERV rating without artificially inflating efficiencies by resorting to temporary static charges. Now we can achieve a true mechanical MERV rating throughout the filter’s lifespan.
Why is Nanofiber So Great?
Improved Filtration
Nanofiber provides a true mechanical MERV rating with the low-pressure drop commonly associated with electrostatic filters or lower MERV rated mechanical filters.
Reduces Expenses
Our Nanofiber technology allows for an airflow greater than you would normally achieve with standard pleated filters. This results in less strain on your HVAC system, helping to reduce HVAC related expenses.
Less Wasteful
Nanofiber uses up to 70% less plastic material to create the same MERV rating as traditional and electrostatic filters. One 24" x 24" x 2" filter offsets the equivalent of eight 12oz plastic bottles.
Eliminate Odors and Volatile Organic Compounds, for good.
Our HVAC filters are the only filters to have the revolutionary, patented ODOGard® coating that eliminates odors at the molecular level, making it impossible for the odor to survive. Even the toughest, seemingly permanent odors don’t stand a chance against ODOGard.
