Keep Air Filters Clean (Change Disposable Filters Regularly)

It’s one of the simplest home maintenance tasks—and also one of the most commonly overlooked.

Changing your HVAC system’s disposable air filter regularly can have a major impact on your home’s overall comfort in Bremerton. Whether you’re trying to improve the air quality inside your home, protect your HVAC system, or lower your utility bills, keeping your air filter clean is a small habit with big benefits.

If you’re not sure when you last changed your air filter—or even where it is—don’t worry. You’re not alone. Our team at Dana’s Heating & Cooling will help you take a closer look at why this simple step matters, how often to change it, and how to choose the right filter for your home.

Why Clean Air Filters Matter

Your HVAC system’s air filter plays an essential role in maintaining indoor air quality. As air circulates through your home, the filter traps dust, pollen, pet dander, mold spores, and other airborne particles.

This filter not only helps protect the health of you and your family, but also keeps dirt and debris from accumulating inside your heating and cooling equipment.

When the filter becomes clogged with buildup, airflow is restricted. That forces your HVAC system to work harder to push air through, which leads to higher energy usage and increased wear and tear. A dirty filter can even contribute to system overheating, short cycling, or frozen coils—none of which you want to deal with during peak heating or cooling season.

Simply put, keeping your air filters clean protects your system and improves your comfort.

How Often Should You Change Your Air Filter?

The answer depends on a few factors, including the type of filter you’re using, the size of your Bremerton, home, whether you have pets, and if anyone in your household has allergies or respiratory concerns.

As a general guideline:

• Basic 1-inch filters: Change every 1–2 months
• High-efficiency pleated filters: Change every 3 months
• Homes with pets or allergy sufferers: Change every 30–60 days
• During high-usage months (summer and winter): Check filters monthly

If you’re unsure, set a reminder to inspect your filter every 30 days. If it looks gray, dusty, or clogged, it’s time for a replacement.

Choosing the Right Filter

Disposable HVAC filters come in a variety of styles and efficiency ratings. The most common measurement is MERV (Minimum Efficiency Reporting Value), which ranges from 1 to 16. The higher the MERV rating, the more particles the filter can trap—but it may also restrict airflow if your system isn’t designed for it.

For most residential homes in Bremerton, and surrounding communities, a filter with a MERV rating between 8 and 13 offers a good balance of filtration and airflow. These filters capture dust, pollen, and pet dander without putting too much strain on your system.

If someone in your home has severe allergies or asthma, or you’re concerned about very fine particles like smoke or bacteria, consider a higher-rated HEPA filter or consult your HVAC technician about upgrading your system to handle advanced filtration.

Signs Your Filter Needs Changing

Even if you’re not checking your calendar, your home may give you clues that your air filter is overdue for a change. Look for:

• Dust buildup around vents and on furniture
• Musty or stale odors
• Unexplained increase in allergy symptoms
• Reduced airflow from registers
• System running longer than usual to maintain temperature

These are all signals that airflow is restricted and your HVAC system may be struggling.

Don’t Forget About Seasonal Changes

Spring and fall are great times to check your air filter, especially if you’re switching between heating and cooling. In spring, allergens like pollen and mold spores can increase the load on your filter. In fall and winter, when Bremerton, homes are sealed up tightly and systems run more often, filters can clog faster with indoor dust and pet dander.

Keeping up with seasonal changes ensures your filter can handle what the weather brings.

Added Benefits of Regular Filter Changes

Beyond keeping the air cleaner and your system healthier, changing your filter regularly can also:

• Improve energy efficiency, reducing utility bills
• Extend the lifespan of your HVAC equipment
• Maintain consistent airflow and temperature throughout your home
• Lower the risk of costly repairs caused by overworked components

It’s a quick fix that pays off in both comfort and savings.

Make It a Habit

Changing your disposable air filter doesn’t require tools, a technician, or a lot of time—just a little consistency. Keep spare filters in a closet or utility area so they’re ready when you need them. Write the replacement date on the frame with a marker or set recurring reminders on your phone or calendar app.

If you’re scheduling seasonal HVAC maintenance, changing the filter at the same time can make it part of your routine. Your technician can also recommend the best filter type for your HVAC equipment and check for any issues that might be reducing your system’s efficiency.

Clean Filter, Cleaner Air, Better Comfort

Something as simple as a clean air filter can make a big difference in how your home feels—and how your HVAC system performs. If you want cleaner air, fewer breakdowns, and lower energy costs, start by checking that filter.
