Living in the Phoenix Valley comes with plenty of perks—beautiful landscapes, warm weather, and a thriving community. But it also means dealing with dry, dusty air and frequent allergens. For homeowners looking to improve indoor air quality, two popular options often come up: Air Scrubbers and Air Filters. But which one is better for your home?
In this comprehensive guide, we'll explore the differences between air scrubbers and filters, how they work, and which option might be best for your specific needs in the unique climate of the Phoenix Valley. According to the Environmental Protection Agency (EPA), "The most effective ways to improve your indoor air are to reduce or remove the sources of pollutants and to ventilate with clean outdoor air" with filtration serving as "an effective supplement to source control and ventilation" (EPA, 2022). And if you're looking for professional advice, Viking HVAC is here to help with free consultations and discounts on air scrubbers when combined with a new AC installation.
Understanding Indoor Air Quality in the Phoenix Valley
Before diving into air purification solutions, it's important to understand why indoor air quality is particularly challenging in the Phoenix Valley region.
The Phoenix Valley Air Quality Challenge
The Phoenix metropolitan area faces unique air quality challenges due to:
Arid Climate: The dry desert environment means more dust particles constantly circulating in the air.
Urban Heat Island Effect: Phoenix's concrete jungle absorbs and radiates heat, creating air circulation patterns that can trap pollutants.
Monsoon Season: During summer monsoons, dust storms (haboobs) can dramatically increase particulate matter both outdoors and indoors.
High Pollen Counts: Despite the desert environment, the Valley has numerous non-native plants and trees that produce significant allergens, particularly in spring.
Limited Rainfall: With minimal precipitation to naturally clean the air, pollutants tend to linger longer than in wetter climates.
According to the American Lung Association, Phoenix ranks among the top cities for year-round particle pollution, making effective indoor air quality solutions especially important for Valley residents.
What Are Air Scrubbers and Air Filters?
Let's break down what these systems are and how they work to purify your home's air.
Air Filters: The Standard Option
Air filters are the most common way to improve indoor air quality. They are typically built into your HVAC system and work by trapping particles such as dust, pollen, pet dander, and mold spores as air circulates through your system.
How Air Filters Work
Air filters catch particles as air passes through a mesh or pleated surface. The filter media physically blocks contaminants from entering your home's air circulation system. Different filters have different capabilities based on their MERV (Minimum Efficiency Reporting Value) rating, a system developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) that measures a filter's ability to capture particles (ASHRAE):
MERV 1-4: Basic filters that catch large particles like dust and pollen
MERV 5-8: Medium-efficiency filters that trap smaller particles like mold spores
MERV 9-12: High-efficiency filters that capture very fine particles
MERV 13-16: Hospital-grade filters that can trap bacteria and some viruses
HEPA Filters: True HEPA filters can capture 99.97% of particles as small as 0.3 microns (EPA)
Advantages of Air Filters
Cost-effective: Relatively inexpensive initial investment
Simple to install: Most HVAC systems are designed to accommodate filters
Variety of options: Different MERV ratings available to suit various needs
Proven technology: Decades of use have demonstrated their effectiveness for many common air quality issues
Limitations of Air Filters
Passive technology: Only filters air that passes through the HVAC system
Regular replacement: Need to be changed every 1-3 months depending on usage and environment
Airflow restriction: Higher MERV ratings can restrict airflow and put strain on your HVAC system
Limited reach: Only purifies air, not surfaces
Cannot eliminate gases or odors: Standard filters don't address chemical pollutants or smells
Air Scrubbers: The Advanced Solution
Air scrubbers take air purification to the next level. Unlike air filters, air scrubbers actively remove contaminants from the air and surfaces throughout your home. Viking HVAC installs Aerus Air Scrubbers that use ActivePure® Technology, which is proven to reduce up to 99.9% of contaminants.
How Air Scrubbers Work
Air scrubbers use advanced technology that goes beyond simple filtering:
Active Purification: Rather than waiting for air to pass through, many scrubbers actively send out purifying agents into your home.
Ionization: Some scrubbers produce negatively charged ions that attach to positively charged particles like dust, causing them to clump together and fall out of the air.
Photocatalytic Oxidation (PCO): Advanced scrubbers use UV light and a catalyst to create molecules that break down pollutants, similar to how sunlight naturally purifies outdoor air.
Surface Sanitization: The purifying molecules can settle on surfaces throughout your home, reducing bacteria and viruses on countertops, doorknobs, and other high-touch areas.
Advantages of Air Scrubbers
Comprehensive purification: Addresses both airborne and surface contaminants
Active technology: Continuously works throughout your entire home
Eliminates microscopic threats: Effective against bacteria, viruses, and VOCs (Volatile Organic Compounds)
Odor elimination: Breaks down molecules that cause unpleasant smells
Low maintenance: Typically requires service only once a year
Whole-home solution: Purifies every room connected to your HVAC system
Limitations of Air Scrubbers
Higher initial cost: More expensive upfront investment
Professional installation: Usually requires expert installation
Technology variations: Different brands and models offer varying levels of effectiveness
Energy usage: May increase electricity consumption slightly

Why Air Quality Matters in the Phoenix Valley
The Phoenix Valley's unique environment can significantly impact your indoor air quality. According to the American Lung Association, Phoenix ranks among the top cities for year-round particle pollution, making effective indoor air quality solutions especially important for Valley residents. Common local pollutants include:
Natural Desert Pollutants
Dust and minerals from the arid landscape can infiltrate even well-sealed homes
Pollen from desert plants including mesquite, palo verde, and non-native landscaping
Seasonal allergens that vary throughout the year, with peak seasons in spring and fall
Urban Pollutant
Vehicle emissions from Phoenix's car-dependent infrastructure
Industrial pollutants from manufacturing and processing facilities
Construction dust from the Valley's continuous development
Indoor Pollutants
Pet dander from indoor animals
Cooking byproducts including smoke and grease particles
Cleaning chemicals and other household VOCs
Mold spores that can develop even in our dry climate, especially in bathrooms and kitchens
The EPA notes that "common contaminants that can be found indoors include particulate matter (including PM2.5 [fine] and PM10 [coarse]), formaldehyde, mold, and pollen" and since "most people spend about 90% of their time indoors, mostly in their homes, much of their exposures to airborne pollutants will happen in the home" (EPA, 2022).
Poor indoor air quality can lead to both immediate and long-term health effects:
Short-term symptoms: Allergies, respiratory irritation, headaches, fatigue, and eye irritation
Long-term concerns: Potential development or worsening of asthma, COPD, and other respiratory conditions
Installing an air scrubber or high-quality air filter can help create a healthier environment for you and your family by addressing these concerns.
Which One Is Better for Your Phoenix Valley Home?
The best choice depends on your specific situation, health concerns, and budget.
When to Choose an Air Filter:
You're mainly concerned about dust, pet hair, and larger allergens
You're on a limited budget and need a simple, effective solution
You're diligent about replacing filters regularly
You have minimal respiratory concerns or allergies
You rent your home and need a temporary solution
When to Choose an Air Scrubber:
You want to eliminate viruses, bacteria, and other microscopic particles
You want an all-in-one solution that purifies air and surfaces
You struggle with severe allergies or asthma

This powerful combination ensures maximum protection against particles of all sizes while extending the life of your filter and HVAC system.
Special Considerations for Phoenix Valley Residents
Living in the unique climate of the Phoenix Valley means certain factors should influence your decision:
Dust Storm Season
During monsoon season (June through September), the Valley experiences dramatic dust storms. These events can drastically increase the particulate matter in your home. Air scrubbers provide an advantage during these periods by actively working to clean the air rather than waiting for it to cycle through a filter. Research shows that "portable air cleaners and HVAC filters can reduce indoor air pollution; however, they cannot remove all pollutants from the air" (EPA).
High AC Usage
Phoenix residents run their air conditioning systems more than most Americans, which means:
Your HVAC filter works overtime
More opportunity for an air scrubber to distribute purifying molecules
Higher potential for energy savings with a clean, efficient system
Winter Visitors
Many Phoenix homes welcome winter visitors or have part-time residents. Air scrubbers can help maintain air quality even when the home is unoccupied for extended periods, reducing musty odors and preventing mold growth. This aligns with ASHRAE's standards for ventilation and acceptable indoor air quality, which are the recognized standards for ventilation system design (ASHRAE).
