Sanders filtration systems

The problem

Reduce Risk Of Airborne Viral Transmission.

Air volume is the largest surface in any building and must be cleaned and filtered. COVID-19 is likely, at least in part, transmitted through the air, and in HVAC systems. Current HVAC filters cannot protect against sub-micron pathogens such as COVID-19 which can travel through the HVAC systems. (ASHRAE 2020) (OSHA 2020) *

The solution

Innovation In HVAC And Room Filtration

With efficiencies as high as 99.9998%, Sanders containment filters remove sub-micron particles the size of known viruses and bacteria from the air. For the first time a solution that allows NIOSH N-99 Filtration without the need for HVAC system retrofit. Using a simple cut to fit pad, these filters can be applied to any current standard HVAC system or on a simple air mover for a quick and efficient “scrub” of the air. Treat and filter your facility from sub-micron particles and allergens and reduce the threat of viral transmission. During a viral respiratory disease outbreak, “we cannot guarantee the air we breathe is clean, so we must assume it is not.” Large volume indoor spaces such as airports, schools, hospitals, cruise ships, and physician offices are typical candidates that benefit the greatest.


Reduce over 80%-95% of the sub-micron particles (1 hour/4+ hours) and has efficiencies as high as 99.99980% BFE. Sanders Containment Filter filter can be retrofitted in residential and commercial HVAC systems. Our cutting-edge synthetic media has MERV 16 efficiencies at .1 micron, capturing particles the size of known pathogens, including Influenza A, H1N1, viruses, bacteria and fungi.

MERV EXPLAINED: Minimum Efficiency Reporting Values

These ratings report a filter’s ability to capture larger particles between 0.3 and 10 microns (μm). The higher the MERV rating the better the filter is at trapping specific types of particles. Sanders containment filters are rated to capture particle @ 0.1 micron (μm) which is beyond the capabilities of MERV rated filters.


MERV 6 – not sub micron rated (3.0-10.0μm particles)
MERV 10 – not sub micron rated (1.0-3.0μm particles)
MERV 14 – 0.3 (μm) @ 50%
MERV 16 – 0.3 (μm) @ 95%
SANDERS – 0.1(μm) @ 99.25% or greater

Electrostatic trap sub-micron particles that contribute to viral outbreaks, colds, flu, allergies, and asthma caused by mold.


The primary function of residential and light commercial HVAC systems is to heat and cool spaces. Filters protect the blower motors and condenser coils, not filter out sub-micron particles such as bacteria, viruses, and particulate matter under .3(μm). The addition of a higher rated filter system offering additional particulate filtering may cause numerous consequences to airflow, electrical load, and mechanical components' longevity. Sanders Filters address the weakness in traditional HVAC design by maintaining high flow rates that do not significantly change a system's dynamics and added functionality from efficient 0.1 (μm) electrostatic trap filtering. Using higher efficiency MERV 16 or HEPA filters may lead to potential problems through significantly increased energy use (>5%)* and usability. Systems using lower rated MERV filters that are already close to blower performance limits may exceed the performance limits with MERV 16 filters' addition.

Corona viruses are spherical particles averaging about 0.125 micron, measured by electron microscope (Zhu et al, 2020)
