What Merv filter will stop Covid?
What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses.
09 μm.) The diagram below demonstrates that MERV 16 filters trap up to 96% of virus-sized particles*, to help prevent the proliferation of airborne viruses in the home.
What is a hospital grade air filter?
Hospital grade HEPA air purifiers are devices with a higher air cleaning capacity compared to most of the random portable products you see around. They are carefully designed for all-round action, and really makes a difference where ever it is used.
What are HEPA filters in hospitals?
What is a Medical-Grade HEPA filter? HEPA filters known as High-Efficiency Particulate Arrestance filters were originally developed to filter fine radioactive particles. A HEPA filter will filter with a minimum efficiency 99.97% of particles at 0.3 microns and 95% of particles at 0.1 microns.
Is MERV 11 too restrictive?
A MERV 11 air filter has a higher efficiency rating. Meaning, it can capture finer particles and clear more contaminants out of the air. … In most cases, a MERV 11 air filter isn’t too high for residential use.

Are MERV 13 filters good for face masks?
MERV-13 filters are engineered to effectively block impurities down to sub-micron levels (. 3 microns) with 99.97% efficiency. These filters offer the highest level of face mask insert filtration available, while maintaining breathability. … Thus, MERV-13 is considered by most to be the optimal face mask filter.
What MERV rating does Lennox recommend?
