How Does An Air Scrubber Work

An air scrubber works in different stages that help it to remove pollutants from the indoor air efficiently. These stages ensure that the indoor environment is filled with safe air so that people inside a home can breathe easily.

Here are the 6 stages of air filtration of an air scrubber:

• Stage 1: Blower: In the initial stage, the blower (fan) pulls the air from the indoor environment. It makes sure that the air is getting pulled and goes inside the air scrubber efficiently.
• Stage 2: Pre-Filter: In the second stage, the blower sends the polluted air to the pre-filter. The air passes through this filter and the large airborne particles get captured by it. After this, the air goes through the next stages.
• Stage 3: Primary Filter: The air that is filtered by the pre-filter goes to the primary filter (HEPA filter) in the third stage. Here small airborne particles that have a size of less than 1 micron are captured.
• Stage 4: Carbon Filter: The gaseous substances don’t get captured by the primary filter. So in the fourth stage, the carbon filter removes most of the gaseous substances from the air which enhances the filtration process.
• Stage 5: UV Light: In the sixth stage, pathogens like viruses and bacteria that survived through all stages are eliminated by the UV light. When the air passes through the UV light all pathogens get killed as a result clean air is provided.
• Stage 6: Blower: In the last stage, the filtered air goes to the blower again. The blower throws the air into the indoor environment and this cycle repeats again and again to keep the air pure.
