EPA（米国環境保護庁） はダクトに防カビなど勧めてくる業者に注意してくださいと警告しています。ダクトは清掃か交換です。日本のハウスメーカーさんからもダクトに防カビはやめてほしいと言われています。防カビコート等は化学物質を吸い込むため推奨されていません。（防カビビジネス業者に注意）防カビをしても汚れが積もってそこにカビが生えますので定期的なメンテナンスでカビを生やさないようにしましょう。

Air duct cleaning service providers may tell you that they need to apply chemical biocide to the inside of your ducts as a means to kill bacteria (germs) and fungi (mold) and prevent future biological growth. They may also propose the application of a "sealant" to prevent dust and dirt particles from being released into the air or to seal air leaks. You should fully understand the pros and cons of permitting application of chemical biocides or sealants. While the targeted use of chemical biocides and sealants may be appropriate under specific circumstances, research has not demonstrated their effectiveness in duct cleaning or their potential adverse health effects. No chemical biocides are currently registered by EPA for use in internally-insulated air duct systems.
