Air Scrubber vs. Air Purifier: What’s the Difference?

Highlights:

• Learn why indoor air quality matters.
• Explore the difference between an air scrubber and an air purifier.
• Discover how each system works to make it easier to pick the best option.

Introduction

An air purifier is a consumer-grade device that typically uses a HEPA filter to trap airborne particles. An air scrubber is a system that often utilizes active technology, such as UV light or ionization, to sanitize the air and surfaces. While air purifiers are ideal for eliminating allergens and dust, air scrubbers are better suited to prevent odors, germs, and mold.

Understanding how each system works when comparing an air scrubber and an air purifier makes it easier for homeowners to decide which is a better fit for their specific indoor air quality (IAQ) needs.

What Is an Air Purifier and How Does It Work?

An air purifier helps improve IAQ, using a fan to pull air through HEPA or carbon-activated filters to trap pollutants. Most units are portable and designed for in-home use.

HOW HEPA FILTRATION REMOVES AIRBORNE PARTICLES

HEPA filters are designed to capture dust, pet dander, pollen, and other types of allergens.

BEST USES FOR AIR PURIFIERS

Air purifiers provide excellent dust reduction and allergy relief in small living spaces. They are best suited for areas that require targeted solutions, such as nurseries, kitchens, and bedrooms.

PROS AND CONS OF AIR PURIFIERS

• PROS: Air purifiers offer passive filtration and seamlessly blend into the surrounding area with aesthetically pleasing designs. They are lightweight, compact, affordable, and considerably quieter than air scrubbers.
• CONS: Air purifiers tend to have high operating costs, with a significant upfront purchase price and recurring electricity use and filter replacements.

What Is an Air Scrubber and How Does It Clean Your Air?

Air scrubbers go beyond filtration, using UV light and ionization to actively treat and sanitize indoor air and surfaces. The integrated system is commonly used to eliminate mold, odors, and germs, providing whole-home coverage.

ACTIVE AIR CLEANING TECHNOLOGIES EXPLAINED

Common household air scrubber technologies are engineered to remove particles, pathogens, volatile organic compounds (VOCs), and gaseous pollutants through chemical, electrical, and mechanical methods.

Active air purification methods include:

• Activated carbon
• HEPA filtration
• Photocatalytic oxidation (PCO)
• UV-C light

These systems can be integrated into existing HVAC systems to remove contaminants and eliminate odors.

WHAT AIR SCRUBBERS ARE BEST AT

Air scrubbers are best suited for homeowners seeking whole-home coverage. They are an ideal solution for reducing odors, molds, spores, germs, and other contaminants that filters alone may not fully capture.

PROS AND CONS OF AIR SCRUBBERS

Air scrubbers offer whole-home coverage and can be integrated into existing industrial air filtration systems. However, they do require professional installation and regular maintenance, resulting in slightly higher operating costs.

Filtration vs. Active Cleaning: Key Differences Homeowners Should Know

Each option offers distinct advantages and disadvantages for improving IAQ. It is important to consider these differences to ensure the system addresses current needs.

PARTICLE REMOVAL VS. AIR AND SURFACE SANITATION

While air purifiers are specifically designed to trap particles, air scrubbers effectively neutralize contaminants.

WHOLE-HOME SYSTEMS VS. STANDALONE DEVICES

Portable air purifiers provide localized filtration and are an ideal solution for specific spaces in the home that require pure IAQ, such as nurseries, kitchens, bedrooms, etc.

Air scrubbers, on the other hand, can be integrated into HVAC ductwork to deliver whole-home coverage, with active surface sanitation and germ reduction throughout the house.

Which One Is Right for My Home?

Air purifiers are a common choice among renters. The plug-and-play units are best suited for specific rooms that require a targeted solution. Air scrubbers are the best option for homeowners seeking a comprehensive, whole-house integrated air treatment system to break down pollutants on surfaces and in the air.

CHOOSE AN AIR PURIFIER IF…

An air purifier is the best option for users who want to address localized air concerns, such as:

• Allergies
• Dust
• Pet Dander

CHOOSE AN AIR SCRUBBER IF…

An air scrubber is ideal for eliminating the following contaminants to achieve whole-home air quality improvement:

• Germs
• Mold Concerns
• Odors
