The first thing that a biohazard cleaning service does when they get to a site is remove the odour source, such as a decomposing pet or human body. Once the odour source is addressed, a cleaning crew assesses the situation in the indoor environment. In most cases, the odour removal stage of biohazard cleaning is usually the hardest because a crew must ensure that indoor air is fresh before proceeding. It is why biohazard cleaning teams use the most effective odour removal devices to accomplish the task, some of which are highlighted in this post.

Air Scrubbers — Air scrubbers, also known as air filtration devices or AFDs, are some of the most common pieces of equipment that biohazard cleaning teams use to remove decomposing odours. An air scrubber generates negative pressure in a room during operation, which aids in expelling contaminated air while simultaneously drawing in the fresh air. Therefore, you might ask where contaminated air goes to. Notably, biohazard cleaning services know better than blowing indoor air into the external environment and polluting it in the process. Instead, an AFDs is designed to filter contaminated air into a containment. Other types of air scrubbers allow a crew to recirculate contaminated indoor air, thanks to sophisticated filters that remove even the most minute contaminant in the air. One significant advantage with AFDs is that cleaning crews can eliminate the decomposing odour with occupants present.

Ozone Generator — An ozone generator converts the oxygen in a room into ozone, destroying contaminant particulates in the process. Notably, ozone generators are most effective in pre-cleaned environments; therefore, a cleaning crew must do thorough work. Otherwise, it might take the equipment longer than necessary to eradicate decomposing odour. One major difference with ozone generators is that an area must be evacuated before the machine starts running. The reason is that ozone generators are hazardous to pets and humans. Additionally, a biohazard cleaning crew must put up warning signs to deter entry by unsuspecting public members. Residents or occupants can only return when an ozone generator has been removed and adequate ventilation introduced.

Ultra-Low Volume (ULV) Fogger — As its name suggests, an ultra-low volume fogger uses fog to scrub contaminated air. The machine releases cold or wet fog into the air to quickly muffle the foul smell. Its fast action makes ULV suitable for odour removal in large open areas such as halls. The best part is that ULVs can produce extremely tiny droplets that can easily get into hard-to-reach spaces, such as the cracks on walls and furniture joints. First, however, you must cover all delicate items and surfaces such as electric outlets, drywalls or cabinetry.
