Debating over air filters

Living in St Petersburg, Florida, the cooling system is an essential component of the household, but the cooling system operates just about year round, however i hope to shut off the AC, open the windows plus care about some fresh air during the months of January, December plus May. The high heat plus excessive humidity create a big workload for the cooling system, however electric bills are a major part of the budget. I’ve done everything possible to eliminate energy waste. I’ve caulked around windows, weatherstripped doors plus invested into blown-in insulation. I’ve installed ceiling fans to help push the heat up plus out of the house. I close the blinds against the sun during the afternoon, make sure to turn lights off plus avoid running the oven. Having a tightly sealed condo helps to reduce energy waste but also causes some concerns with indoor air quality. The humidity in St Petersburg makes cockroaches, mold, mildew, dust mites plus bacteria correct concerns. I am diligent in cleaning the cooling system coils, condensate drain plus condensate pan. Those are the areas where toxins tend to thrive. I also make sure to change out the A/C air filter every other month. I have looked into all unusual types of air filters. The cheaper air filters with a lower MERV rating don’t capture especially small contaminants. However, they also don’t clog as suddenly. The air filters with a higher MERV rating feature much smaller holes that trap microscopic particles, promoting a cleaner plus healthier residing environment… Unfortunately, they become dirty very suddenly, but once the air filter is clogged, it detracts from cooling system airflow plus energy efficiency.
