Understanding Air Purifiers And Air Scrubbers
Air purifiers and air scrubbers are both devices designed to improve indoor air quality by filtering or cleaning the air, but they work slightly differently.
What Is An Air Purifier?
An air purifier is a device that helps to improve the air quality in a room or space. It removes pollutants, allergens, and other harmful particles from the air, leaving behind cleaner and healthier air to breathe. (1.)
How Does An Air Purifier Work?
An air purifier typically refers to a type of air cleaning that is filter-based.
The most common type is the HEPA filter air purifier, which uses a high-efficiency particulate air (HEPA) filter to trap and remove airborne particles, such as dust, pollen, pet dander, and smoke.
HEPA filters comprise a dense network of fibers that trap particles as air passes through. They can remove particles as small as 0.3 microns in size, which is smaller than the width of human hair.
Some air purifiers also use additional filters, such as activated carbon filters, to remove odors, gases, and chemicals from the air. (2.)(3.)(4.)
Types Of Air Purifiers:
Several types of air purifiers are available, each with unique features and benefits.
Some of the most popular types include:
| Type of Air Purifier | Features and Benefits |
| HEPA filter air purifiers | – Most common type of air purifier, effective at removing airborne particles |
| Activated carbon air purifiers | – Effectively removes odors, gases, and chemicals from the air |
| UV-C air purifiers | – Use ultraviolet light to kill bacteria, viruses, and other microorganisms in the air |
| Ozone air purifiers | – Emit ozone into the air to kill bacteria and other microorganisms. Not recommended for use in occupied spaces due to harmful byproducts |
When choosing an air purifier, you must consider your specific needs and the device’s features.
Some air purifiers are designed for larger spaces, while others are more portable and can be moved from room to room.
Additionally, some air purifiers may be more effective at removing specific types of pollutants than others.
What Is An Air Scrubber?
An air scrubber is a machine that cleans the air inside a home or building.
It is primarily used in commercial settings like factories or building sites but could act as a whole-house air purifier.
Air scrubbers are primarily used to remove chemicals, gases, and toxic particles from the air that come from household projects or indoor issues. (1.)
How Does An Air Scrubber Work?
An air scrubber works by drawing in air from a larger area and then simultaneously decontaminating the air.
The air is then passed through a filter that removes harmful particles such as chemicals, gases, and toxins.
The air is then expelled back into the room or building, providing cleaner and healthier air for individuals to breathe.
There are different types of air scrubbers that work in different ways to clean the air.
| Types of Air Scrubbers | Features |
| Combination filter air scrubbers | – Use a combination of filters like HEPA and activated carbon filters to remove harmful particles. |
| UV-C air scrubbers | – Use UV-C light to kill bacteria and viruses in the air. |
| Portable air scrubbers | – Can be easily moved from room to room. Typically used for smaller spaces. |
| Stationary air scrubbers | – Installed in a specific location. Used for larger spaces like warehouses or factories. |
| Negative air machines | – Create negative air pressure in a room or building. Prevent harmful particles from escaping into other areas. Commonly used in healthcare settings like hospitals or clinics. |
What’s The Difference Between An Air Purifier And An Air Scrubber?
Air scrubbers and air purifiers may seem similar, but their technology and mechanisms differ.
Key Differences In Technology And Mechanisms
Understanding the differences in technology and mechanisms between air purifiers and air scrubbers is essential in deciding which one is best for you.
Here is a comprehensive comparison of the two systems:
| Air Purifier | Air Scrubber |
| Uses HEPA, activated carbon, or other filters to capture particles and pollutants from the air | Utilizes UV-C light, ozone, or other chemical processes to neutralize or eliminate contaminants |
| Primarily designed for removing dust, pollen, mold spores, and other airborne particles | Primarily targets gases, odors, VOCs, and bacteria, as well as particles |
| Filters need to be replaced periodically, adding to maintenance costs | Some models require minimal to no filter replacements, reducing maintenance costs |
| Often quieter, as they rely on filters and fans to clean the air | May produce some noise from the fan, but models utilizing UV-C light or ozone can operate silently |
| More suitable for residential and small commercial settings | Can be used in residential, commercial, and industrial settings, depending on the model’s capacity |
| Generally less expensive upfront, but filter replacements add to long-term costs | Typically more expensive upfront, but may offer lower long-term costs due to reduced maintenance |
By examining these fundamental differences, you can better understand how air purifiers and air scrubbers work and ultimately choose the most suitable option for your specific needs.
