Air quality in indoor spaces is an often-overlooked aspect of our daily lives, yet it can significantly impact our health and comfort. Air scrubbers, a specialized kind of air purifier, play a vital role in improving indoor air quality by removing particles, gases, and chemicals from the air. These devices are especially critical in environments where air quality is compromised due to pollutants, allergens, or contaminants such as dust, mold spores, or chemical fumes. By drawing air through filters and often using additional technology like UV light or negative ions, air scrubbers effectively cleanse the air we breathe every day.
An air scrubber is a device specifically engineered to improve the air quality within your home or commercial building. Attached directly to the existing HVAC system, air scrubbers work seamlessly with the heating and cooling units to remove various airborne contaminants. This technology can effectively target pollutants such as dust, dander, volatile organic compounds (VOCs), and even microorganisms like bacteria and viruses from the indoor atmosphere.
The operation of an air scrubber involves drawing in air from the living space, filtering it through a series of mechanisms to capture impurities, and recirculating cleaner air back into the environment. These devices are particularly beneficial for people with allergies or respiratory conditions, as they can greatly reduce the presence of irritants that commonly provoke symptoms.
Different types of air scrubbers, including dry, wet, and thermal oxidizers, cater to diverse needs and settings. Whether they use physical filters, chemical reactions, or ultraviolet light, these systems share the common goal of delivering a cleaner and healthier indoor air quality. Their use extends beyond residential to commercial and industrial applications.

Overview of Air Scrubbers
Air scrubbers have become a go-to solution in the quest for cleaner indoor air. They are integral components of modern air purification systems, effectively removing a myriad of airborne contaminants.
Definition and Purpose
Key Components of Air Scrubbers
The efficacy of these devices depends on their several key components:
- Filters: Capture solid particulates like dust and pollen.
- Germicidal UV Light: Targets and deactivates microorganisms such as bacteria and viruses.
- Catalytic Process: Engages in chemical reactions that reduce odors and volatile organic compounds (VOCs).
Main Types of Air Scrubbers
There are mainly two types:
- Portable Air Scrubbers: Designed for temporary use in specific areas.
- Installed Units: Integrated into HVAC systems for continuous air scrubber technology throughout a building.
Air Scrubbers vs. Air Purifiers
While they share a common goal to purify air, air scrubbers and air purifiers have distinct methods of operation:
How Air Scrubbers Work
Air Scrubber Work Process
An air scrubber work process begins when air enters the device containing a series of filters. These filters trap particles such as dust, allergens, and other contaminants. The air moves through these filters, often including a pre-filter for larger particles, a HEPA filter for fine particles, and an activated carbon filter for odors and gases.
The Role of UV Light
Post-filtration, the air passes by a UV light. This UV light is crucial because it uses ultraviolet radiation to inactivate microorganisms, including bacteria, viruses, and mold spores, making the air not just cleaner but also more hygienic.

Types of Contaminants Addressed
Volatile Organic Compounds
Volatile organic compounds (VOCs) are gases that are released from certain solids or liquids, often found in household products like paints, varnishes, and cleaning agents. VOCs can have short- and long-term adverse health effects. Air scrubbers are effective in reducing VOCs in the indoor environment, making the air safer to breathe.
Particulate Matter and Larger Particles
Microorganisms and Allergens
Finally, air scrubbers address various microorganisms and allergens, including bacteria, mold spores, and viruses. They help minimize exposure to these potential pathogens and allergens, contributing to a cleaner, healthier living environment. Their ability to kill particulates and organisms like mold and viruses is one of the key benefits of incorporating air scrubbers into HVAC systems.
Air Scrubber Technology
HEPA Filter Integration
HEPA filters are a cornerstone in air scrubber technology; they effectively trap particles as small as 0.3 microns with a 99.97% efficiency rate. Integration of HEPA filters in air scrubbers ensures that common allergens like dust, pollen, and dander are removed from the indoor environment.
Germicidal Light Technology
Utilizing Germicidal light , or ultraviolet (UV) light, air scrubbers provide an extra layer of purification by inactivating airborne pathogens. Technologies like ActivePure® go further by not only trapping but also neutralizing harmful microorganisms, making them a powerful agent against mold, viruses, and bacteria.
Electronic and Ionic Technologies
Air scrubbers may employ electronic or ionic technologies to charge particles with a negative or positive charge, causing them to clump together for easier filtration. This is especially beneficial for capturing smoke and minuscule particulates that would otherwise pass through traditional filters.

Comparing Different Models
When comparing different models, one should examine:
- CADR (Clean Air Delivery Rate)
- Filter types and durability
- The presence of UV-C light for enhanced purification
It's also advisable to consider user reviews and any certification or endorsement by health and industry standards, as these can provide additional assurance of the unit's performance and reliability. Given the variety of options on the market, comparing models thoroughly is key to finding the right fit.

Maintenance and Upkeep
Cleaning and Replacing Filters
Frequently inspect the primary filter and air filters for accumulations of dust and debris. For most air scrubbers, cleaning reusable filters every 6 to 12 months is recommended, while disposable filters should be replaced within the same interval to sustain peak performance. Failure to adhere to these guidelines can reduce the efficiency of an air scrubber and compromise air quality.
