i was told that a high merv will make the furnace to work harder and can reduce its lifetime. So what's the solution.

[@MEPAcademy]

You may need to upgrade your fan motor to a higher static pressure version if your AC Contractor determines that the existing fan lacks the static pressure to overcome the additional resistance created by a thicker, higher static drop filter.

As Engineers and Contractors, we are sought out for advice on how to deal with those things that come along in life that create anxiety for the public. Providing solutions is what a good engineer or contractor does for their customers who have concerns about these issues. We put HEPA filtration systems in for dentists, hospitals, pharmaceutical manufacturers, microelectronic manufacturers and laboratories. The technology is scientifically proven to work as reflected in research papers.
