Therefore, here we are sharing more information from EPA (United States Environmental Protection Agency) about how to prevent duct contamination so that your ducts keep healthier:

“How to Prevent Duct Contamination

Whether or not you decide to have the air ducts in your home cleaned, committing to a good preventive maintenance program is essential to minimize duct contamination.

To prevent dirt from entering the system:

checkmarkUse the highest efficiency air filter recommended by the manufacturer of your heating and cooling system.
checkmarkChange filters regularly.
checkmarkIf your filters become clogged, change them more frequently.
checkmarkBe sure you do not have any missing filters and that air cannot bypass filters through gaps around the filter holder.
checkmarkWhen having your heating and cooling system maintained or checked for other reasons, be sure to ask the service provider to clean cooling coils and drain pans.
checkmarkDuring construction or renovation work that produces dust in your home, seal off supply and return registers and do not operate the heating and cooling system until after cleaning up the dust.
checkmarkRemove dust and vacuum your home regularly. (Use a high efficiency vacuum (HEPA) cleaner or the highest efficiency filter bags your vacuum cleaner can take. Vacuuming can increase the amount of dust in the air during and after vacuuming as well as in your ducts).
checkmarkIf your heating system includes in-duct humidification equipment, be sure to operate and maintain the humidifier strictly as recommended by the manufacturer.”
