When the summer heat kicks into high gear, your air conditioner becomes one of the most important appliances in your home. It keeps you cool, comfortable, and—if your system is well-maintained—it can also help you breathe cleaner, healthier air. But even the best air conditioning system can’t perform at its best without a properly chosen and maintained air filter.
At Delta T Heating & Air, we often talk with homeowners who don’t realize just how big of a role their air filter plays in their home’s comfort and air quality. Whether you’re concerned about allergies, dust buildup, or just want to make your AC run more efficiently, choosing the right filter is a great place to start.

Why Air Filtration Matters in Coastal North Carolina
Living in a coastal climate has many benefits: fresh ocean air, beautiful views, and plenty of sunshine. But it also comes with unique challenges for your indoor air. Increased humidity, salty air, and higher concentrations of airborne allergens can all affect the air inside your home.
A high-quality air filter helps your HVAC system trap these pollutants before they circulate through your living space. Not only does this help reduce dust and allergy symptoms, but it also protects your HVAC components from premature wear. A clogged or inadequate filter can force your AC system to work harder, which can increase energy costs and reduce system lifespan.
If you’ve noticed that your system isn’t cooling as efficiently or your indoor air seems stale or dusty, your air filter might be due for a change or an upgrade. Check out our indoor air quality services for more ways to keep your system running smoothly.
Common Types of Air Filtration Systems
Several types of air filters are available for residential HVAC systems. Each type has pros and cons, and the best one for your home depends on your household’s needs, priorities, and lifestyle.
1. Fiberglass Filters: Basic and Budget-Friendly
Fiberglass air filters are the most common type found in many entry-level or builder-grade HVAC systems. These filters are made with thin layers of spun glass and are designed to capture large airborne particles such as dust and lint. They are inexpensive, usually costing just a few dollars per filter, and are meant to be replaced monthly.
- Pros: Low upfront cost, readily available, easy to replace
- Cons: Limited filtration capabilities, not effective against smaller particles like pollen, pet dander, or smoke
- Best for: Homes without pets or allergy sufferers, or homes where the HVAC system is used infrequently
While fiberglass filters do provide a basic level of protection, they are primarily designed to protect the HVAC system itself rather than significantly improve indoor air quality. They’re a good option for homes with no specific air quality concerns, but not ideal if clean air is a priority.
2. Pleated Filters: Reliable Protection for Everyday Use
Pleated filters are made from polyester or cotton materials folded into accordion-like pleats to increase surface area. This design allows them to trap a wider range of particles, including pollen, pet dander, mold spores, and fine dust.
- Pros: Better particle capture than fiberglass, affordable, widely compatible
- Cons: Can restrict airflow if not changed regularly, may cost slightly more than fiberglass
- Best for: Households with pets, children, or mild allergy concerns
Pleated filters strike a great balance between performance and affordability. For most families, especially those with active households, pets, or frequent AC use, pleated filters offer a solid upgrade in both air quality and system protection.
3. Electrostatic Filters: Reusable and Eco-Conscious
Electrostatic air filters use self-charging static electricity to attract and hold particles. They come in both disposable and washable versions, with the washable models offering a more sustainable option for long-term use. These filters are available in a variety of sizes and thicknesses, and can even be custom-ordered to fit older or non-standard HVAC systems.
- Pros: Effective against fine particles, environmentally friendly if washable, customizable
- Cons: Higher initial cost, washable versions require regular and thorough cleaning
- Best for: Environmentally conscious homeowners or those concerned with smoke, fine dust, or allergens
Electrostatic filters are an excellent solution for families looking to reduce household waste while maintaining cleaner air. Just be sure to keep up with washing if you go the reusable route, as neglecting maintenance can reduce effectiveness.
4. HEPA Filters: Maximum Filtration for Sensitive Households
High Efficiency Particulate Air (HEPA) filters offer some of the most advanced filtration available, capturing up to 99.97% of particles as small as 0.3 microns. These include microscopic allergens like mold spores, bacteria, smoke particles, and even some viruses. HEPA filters are often used in hospitals, labs, and cleanrooms, and are becoming more common in high-end residential applications.
- Pros: Exceptional filtration, ideal for severe allergies or respiratory issues
- Cons: More expensive, not compatible with all HVAC systems, may require system modification
- Best for: Homes with allergy or asthma sufferers, or where indoor air quality is a major health concern
If you or a family member has serious respiratory issues, a HEPA filter could make a noticeable difference in comfort and wellness. However, always consult an HVAC professional before installing one, as many systems aren’t designed to handle the airflow resistance HEPA filters create.
Choosing the Right Filter for Your Needs
With so many options, it can feel overwhelming to choose the best air filtration system. Consider these questions:
- Do you have pets that shed?
- Does anyone in your home have allergies or respiratory issues?
- How often do you use your HVAC system?
- Are you willing to spend more for long-term performance?
