Keeping your home’s air fresh and your HVAC system running efficiently is a real challenge on Florida’s Space Coast. High humidity, salty air, and constant pollen mean your air filter does more than just trap dust. It’s essential for your comfort, health, and energy savings. This guide will explore your options and help you choose the right one for your home.
What Does an HVAC Air Filter Do?
Your HVAC air filter traps airborne particles like dust, pollen, pet dander, and mold spores before they circulate through your home or build up inside your system.
A quality air filter helps you:
- Improve indoor air quality, making breathing easier—especially for allergy sufferers.
- Protect your HVAC system from dust and buildup, reducing wear and tear.
- Maintain strong airflow and system efficiency, which can help lower energy bills.
A clean filter doesn’t just benefit your lungs, it also keeps your HVAC system running smoothly and reliably.
Types of Filters for HVAC
Not all air filters are created equal. Here’s how the most common types perform in Florida’s unique climate:
Fiberglass Air Filters
Fiberglass filters are basic, disposable, and affordable.
- Best for: Budget-conscious homeowners without pets or allergies.
- Strengths: Good at trapping large dust particles and protecting your HVAC equipment.
- Limitations: Less effective at capturing smaller particles like pollen or pet dander, so they don’t do much to improve indoor air quality.
While inexpensive, fiberglass filters aren’t always ideal for the Space Coast’s high pollen and humidity. They won’t help much with allergens or mold spores that are common here.
Pleated Air Filters
Pleated filters are made from folded polyester or cotton, giving them more surface area to trap finer particles.
- Best for: Most homes in humid or high-pollen areas.
- Strengths: Capture more dust, pollen, and mold spores than fiberglass. Available in a range of MERV ratings for different filtration needs.
- Limitations: Higher MERV pleated filters can restrict airflow if your system isn’t designed for them.
Pleated filters are a strong choice for Space Coast homes because they trap pollen and mold spores more effectively, supporting better air quality in our humid, allergy-prone environment.
Electrostatic (Washable/Reusable) Air Filters
Electrostatic filters use self-charging fibers to attract and trap dust and allergens.
- Best for: Homes with pets or high dust levels.
- Strengths: Available in both disposable and washable versions. Washable types can be reused, reducing waste and saving money over time.
- Limitations: Washable filters need regular cleaning (at least monthly) and must be dried completely before reinstalling to prevent mold, especially in Florida’s humidity. Proper care keeps them effective and safe.

HEPA Filters
HEPA (High-Efficiency Particulate Air) filters are the gold standard for removing airborne particles.
- Best for: Severe allergies or asthma.
- Strengths: Capture up to 99.97% of dust, pollen, mold, and even bacteria.
- Limitations: Not all residential HVAC systems can accommodate them due to their density, which can restrict airflow.
HEPA filters are excellent for Florida’s high pollen and mold counts, but you must check system compatibility, as not all units can handle the airflow restriction.
Activated Carbon Filters
Activated carbon filters are designed to remove odors and volatile organic compounds (VOCs).
- Best for: Homes with strong odors from pets, smoke, or cooking.
- Strengths: Excellent at eliminating smells and chemical sensitivities.
- Limitations: Usually used alongside pleated or HEPA filters and need regular replacement.
These filters are helpful for removing musty or coastal odors, but should be paired with a pleated or HEPA filter for full particle filtration.
UV Filters
UV filters use ultraviolet light to neutralize bacteria and mold spores as air passes through your system.
- Best for: Homes concerned about germs and mold, especially in humid climates.
- Strengths: Help control germs and mold.
- Limitations: Do not remove dust or pollen and should be paired with another filter type for complete protection.
UV filters are particularly useful in Florida’s humid climate to help control mold and bacteria growth inside your HVAC system.
What Kind of Air Filter Do I Need for My Home?
Choosing the best air filter depends on your household’s needs and your HVAC system. Consider these factors:
- Allergies or pets: Pleated or electrostatic filters with higher MERV ratings trap more dust and dander.
- Odors: Activated carbon filters help keep your air smelling fresh.
- Reusability: Washable filters reduce waste, but require regular, careful cleaning, especially in Florida’s humidity.
- System compatibility: Not all systems can handle high-MERV or HEPA filters. Always check your owner’s manual or ask an Ellington technician for guidance.

How Do I Change My Home Air Filter?
Changing your air filter is quick and easy:
- Turn off your HVAC system.
- Remove the old filter from its slot (usually in a return vent or air handler).
- Insert the new filter, or a cleaned reusable one, making sure the arrows match the airflow direction.
- Secure the cover and turn your system back on.
Check your filter size before buying replacements, and inspect your filter monthly, especially during heavy use. For a full walkthrough, visit our Space Coast HVAC maintenance guide.
How Often Should I Change My HVAC Filter?
Most disposable filters should be replaced every 1–3 months. You may need to change them more often if:
- You have pets or allergies
- You notice dust building up quickly
- Airflow from your vents is reduced
- There’s a musty or stale odor when your system runs
Washable filters should be cleaned monthly. Regular filter changes are a key part of HVAC maintenance and help keep your system running efficiently and your air clean.
