What's New
We’ve improved the filtration and airflow capabilities, so you’re getting a better filter without a price hike. This filter features 2.5x the filtration surface area compared to standard air filters.
Better Filtration
Simplified Installation
The filter works no matter which way it’s installed, so there’s no way to mess up the filter replacement. We’ve carefully designed this filter to maximize efficiency and simplify this chore even more.
We’ve reduced the amount of cardboard used in shipping, which in turn reduces our carbon footprint.
Eco-minded
What's The Same
The exact quantity and size of filters required for replacement are delivered right to you.
Each package includes a personalized message with instructions on how to change the filters.
Filters are delivered on schedule as a timely physical reminder to change them.
FAQ
Absolutely! It uses much of the same base filtration technology as existing air filters, with much-needed improvements to the overall design. You’re actually getting more efficient airflow, which puts less strain on the HVAC unit.
About Second Nature
Is this new filter okay for most HVAC systems?
The Flex-Lock frame is designed to better withstand shipping. Because it’s folded up, it can’t be damaged as easily as regular cardboard filters. Plus, the smaller package size is easier to transport, and more environmentally friendly. When the filter pops into shape, it “locks” into position, stronger than almost any other air filter on the market. When truck space is at a premium, less space per filter means more sizes and types of filters can be carried and less time spent going back to
restock supplies.
Why does it bend? Is that sturdy?
It’s been tested and verified to perform equal to or better than a typical MERV 8 air filter. That means it’s great at removing pollen, pet dander, dust particles and more from your air. In fact, it actually stops up to 97%* more of the smallest particles like bacteria. And unlike a typical MERV 8 air filter that performs worse when installed backward, these air filters are effective and perform well when installed in either direction.
How does this filter perform?
Like many air filters, this filter doesn’t touch or interact with the coils. If any type of air filter goes unchanged for too long it can clog up and restrict air flow to the point an overrun HVAC unit can freeze up. Regular air filter changes will prevent this issue.
Will this filter damage HVAC coils?
We’ve rigorously tested our air filters and verified them to work as expected, but we’re happy to help troubleshoot any issue you may encounter, including examining and testing the air filter to identify any anomalies. We stand behind the research and design of our new innovative filter and will work with you, should the need arise, to help find a root cause.
What happens if something does go wrong?
Due to shipping, portions of the pleated material may appear slightly flat upon opening. However, once installed, the airflow will straighten these pleats out over a few days, and there are no negative impacts to filter efficiency or HVAC compatibility.
The pleats look flat, is that normal?
Better Performance
10% less initial pressure drop compared to standard MERV 8 filters, meaning a more efficient airflow.
Industry-standard ASHRAE 52.2 tests verify this filter meets or exceeds MERV 8 standards.
The soft-edge frame creates a tighter seal, which leads to several particle-stopping improvements.
This new filter has been tested and verified to capture:
97% more of the smallest particles like bacteria*
38% more medium-sized particles like mold spores
16% more of the largest harmful particles like pollen

Design Updates
The frame is constructed from durable medium carbon, spring tempered steel. Strength-wise, the material is comparable to valve springs in car engines. It holds strong well beyond the pressure levels generated in residential HVAC units.
The frame design is similar to designs NASA uses for deploying antennas and solar cells.
The flexibility of the frame means we can package these filters for better durability during shipping, unlike traditional cardboard frames that are subject to collapse.
This new design virtually eliminates damage accidentally caused by the end-user when opening and installing the filter. It also puts an end to damaging inventory while being carried on a service truck.
