Back to Basics: The HEPA Sandwich Method for Mold Remediation
Vacuum. Clean. Vacuum.
Albeit labor-intensive, the “HEPA sandwich” method of traditional mold removal is still one of the most popular methods in the industry. Specifically, this practice occurs following the setup of containment barriers and after the removal and demolition of unsalvageable items and structures. It consists of using a high-efficiency particulate air (HEPA) vacuum to clean semi-porous and non-porous items, then damp wiping or wet cleaning the items, and then implementing another round of HEPA vacuuming to remove any leftover contaminants.
For an even more thorough cleaning, many mold remediation professionals repeat the HEPA sandwich process two to three times.
