Dust on the furniture is easy to see. The smaller particles moving through your home’s air are another story.
Everyday activities, pets, outdoor air, cooking, and other sources can introduce particles and contaminants into your indoor environment. Once inside, some of them may continue circulating as your heating and cooling system moves air throughout the house.
Improving indoor air quality isn’t about finding one product that solves every problem. It usually means understanding what’s affecting your home’s air and choosing the right combination of filtration, ventilation, humidity control, source control, and, in some cases, supplemental air-cleaning technology such as iWave.
What Is Indoor Air Pollution?
Indoor air pollution is a broad term for particles, gases, odors, and other contaminants that can affect the quality of the air inside a home.
Some pollutants originate indoors, while others enter from outside. Common examples may include:
- Household dust and lint
- Pollen brought in from outdoors
- Pet hair and dander
- Smoke and fine airborne particles
- Cooking grease and odors
- Dust mites
- Certain volatile organic compounds (VOCs)
- Biological contaminants in some indoor environments
Humidity also plays an important role in overall indoor comfort. Air that is excessively dry or humid may make the home less comfortable and can contribute to other indoor air quality concerns.
Southside Heating & Air Conditioning offers several indoor air quality solutions, including whole-home air cleaners, filtration, humidification, dehumidification, ventilation, and ionization technology.
Why Can Indoor Pollutants Build Up?
Your home is constantly exchanging air with its surroundings, even when the windows are closed. Pollen, smoke, and other outdoor particles may enter when doors open or through normal air leakage. At the same time, everyday activities inside the house continuously add new particles.
Cooking can introduce grease, odors, and fine particles. Pets contribute hair and dander. Cleaning, hobbies, furnishings, and household products can introduce additional particles or odors.
During a Minnesota winter, homeowners may also spend long stretches with windows closed while the heating system circulates indoor air repeatedly. That makes proper filtration and ventilation particularly important when you’re trying to improve whole-home air quality.
Start With the Sources of Indoor Air Pollution
Before adding air-cleaning equipment, consider what can be done to reduce pollutants at their source.
Simple source-control steps may include:
- Keeping indoor spaces regularly cleaned
- Using kitchen and bathroom exhaust fans appropriately
- Limiting indoor smoke
- Managing moisture problems promptly
- Keeping pets and bedding regularly groomed or cleaned
- Following manufacturer directions when using paints, cleaners, and other household products
Reducing the amount of pollution entering the air in the first place helps lessen the burden on the filtration and air-cleaning equipment that comes afterward.
Filtration Is an Important Part of Indoor Air Quality
Your HVAC filter plays a straightforward but important role: it captures particles as air passes through the heating and cooling system.
Filters come in different sizes and efficiency levels, and a more restrictive filter is not automatically better for every HVAC system. The filter should be appropriate for the equipment so that it provides useful filtration without creating excessive airflow resistance.
Filters also need to be replaced according to their condition and the needs of the system. A heavily loaded filter can restrict airflow and make it harder for your HVAC equipment to move air properly.
If you’re unsure which filter belongs in your system, Southside can help homeowners select the appropriate HVAC replacement filter.
What Is an iWave Air Purifier?
Filtration is only one way to address contaminants circulating through a ducted HVAC system. Another option is ionization technology.
Southside Heating & Air Conditioning offers the iWave-R, an active ionization air purification system designed for installation in residential ducted heating and cooling systems.
Rather than acting as another physical filter, the iWave works within the air stream. As air moves through the HVAC system, the device generates positive and negative ions that travel with the circulating air.
This makes iWave a supplemental air-treatment technology rather than a replacement for your home’s HVAC filter.
How Does Ionization Technology Work?
Ionization can sound complicated, but the basic idea is fairly simple.
The iWave produces charged ions within the HVAC air stream. Those ions can interact with airborne particles as air circulates through the system. One intended effect of the process is causing smaller particles to join together into larger clusters, which may make them easier for filtration to capture.
The manufacturer also positions iWave technology as a way to address certain odors and other airborne contaminants as part of a whole-home air quality strategy.
What ionization does not mean is that you can stop using your HVAC filter or ignore the other factors affecting indoor air quality. Filtration, ventilation, humidity, and the sources of pollutants inside the home all still matter.
iWave vs. Your HVAC Filter: What’s the Difference?
It helps to think of filtration and ionization as doing different jobs.
Your HVAC filter physically captures particles. As return air passes through the filter, particles that the filter is capable of trapping remain in the filter media instead of continuing through the HVAC system.
iWave treats circulating air using ionization. The device adds ions to the air rather than acting as another layer of filter media.
Because the technologies work differently, homeowners shouldn’t think of the choice as “iWave or a filter.” An ionization system may be used alongside appropriate HVAC filtration as part of a broader approach to improving air quality.
Indoor Air Quality Is About More Than Air Purification
One of the most important things to understand about indoor air quality is that no single air cleaner addresses every source of pollution in every home.
A more complete approach may involve several strategies:
- Source control: Reduce pollutants and excess moisture where possible before they enter the home’s air.
- Ventilation: Provide appropriate air exchange so stale indoor air can be replaced with outdoor air when conditions allow.
- Filtration: Capture airborne particles as air passes through the HVAC system.
- Humidity control: Use humidification or dehumidification when indoor moisture levels regularly become uncomfortable.
- Supplemental air treatment: Consider technologies such as iWave when they fit the home’s HVAC system and specific air quality goals.
The right combination depends on your home. A household dealing primarily with dry winter air may need a different solution than a home concerned about seasonal pollen, persistent dust, pet dander, or outside smoke.
Who Might Consider a Whole-Home Air Quality Upgrade?
You may want to take a closer look at your indoor air quality if you regularly notice:
- Dust returning quickly after cleaning
- Pet hair and dander throughout the home
- Seasonal pollen making its way indoors
- Persistent cooking, pet, or household odors
- Smoke or outdoor particles entering the house
- Indoor air that regularly feels excessively dry or humid
- An HVAC filter that doesn’t seem to address your primary concerns
These symptoms don’t automatically mean an iWave is the answer. They are reasons to look at the home’s overall air quality strategy and determine whether filtration, ventilation, humidity control, or additional air treatment could help address the specific concern.
Choosing the Right Indoor Air Quality Solution
Before installing an air cleaner or purifier, it’s helpful to consider how your HVAC system is set up and what you’re actually trying to improve.
An indoor air quality evaluation may consider:
- Your existing furnace or air handler
- The type and condition of your HVAC filter
- Whether your home uses ducted or ductless equipment
- Humidity levels
- Existing ventilation
- The specific particles, odors, or comfort concerns you’ve noticed
That approach helps avoid adding equipment simply because it sounds appealing. The goal should be to choose IAQ solutions that make sense for the home’s existing system and the homeowner’s priorities.
