Is Your Air Filter the Right Size? 16x28x4 Aprilaire vs. 16x25x4
The selection process of HVAC filters requires more than just measurement considerations. I have seen many HVAC systems installed throughout my career which leads to a common question regarding the filter selection between a 16x25x4 and a 16x28x4 Aprilaire model. The two filter dimensions might look equivalent but they can lead to different effects on airflow function as well as filtration capabilities and full system operational output.
In this guide, I’ll share first-hand insights and analysis, offering a detailed comparison. By the end, you’ll have a clearer understanding of which filter will deliver the best results for your specific HVAC setup.
Top Takeaways
1️⃣ Filter Size Matters:
• The right filter size improves air quality, airflow, and system efficiency.
2️⃣ Energy Savings:
• Correct filter choice reduces energy consumption and lowers bills.
3️⃣ Improved Air Quality:
• Upgraded filters reduce indoor pollutants for cleaner air.
4️⃣ Long-Term Investment:
• The right filter extends the HVAC lifespan and lowers repair costs.
5️⃣ Regular Maintenance is Key:
• Replace filters regularly to keep your system running smoothly.
Case Study & Real-World Examples: Reducing the Need for Expensive HVAC Repairs
Here’s how choosing the right filter size made a difference in two real-world cases:
Case 1: Improving Air Quality in a West Palm Beach Home
Problem: A family struggled with poor indoor air quality due to a clogged 16x25x4 filter.
Solution: I recommended upgrading to 16x28x4 Aprilaire HVAC furnace replacement air filters to improve airflow.
Result:
✔️ Air quality improved with fewer dust particles and allergens.
✔️ The HVAC system ran more efficiently, reducing energy usage.
Case 2: Boosting System Efficiency in a Commercial Building
Problem: A commercial property in Boca Raton had inconsistent heating and cooling with a standard 16x28x4 filter.
Solution: Switched to a 16x25x4 filter to better match the system’s airflow.
Result:
✔️ Energy consumption dropped by 15%.
✔️ The system’s performance became more consistent.
In both cases, selecting the right filter size improved air quality, system efficiency, and energy savings.
“From my years of experience working with HVAC systems, I’ve seen firsthand how the right air filter size can transform both air quality and system efficiency. In one case, switching to a larger filter improved air quality and reduced energy usage, while in another, the right filter change saved 15% in energy costs. The difference isn’t just in the dimensions—it’s in how the filter interacts with the system to optimize performance. Selecting the right filter is more than a specification; it’s about creating a healthier, more efficient environment for your home or business.”

Final Thought & Opinion: Why Size Matters in Filter Selection
Selecting the right furnace air filter is key to maximizing HVAC performance and air quality. Here’s why:
Better Efficiency & Air Quality
• The right filter size improves airflow and filtration, leading to cleaner air and better system performance.
• Whether it’s upgrading to a 16x28x4 filter or choosing a 16x25x4, the correct filter makes a noticeable difference.
Cost-Effective Investment
• In my experience, switching to the right filter pays for itself quickly through lower energy bills and better system efficiency.
• Filters that fit the system properly prevent overwork and reduce energy consumption.
Overlooking Filter Size
• Many people assume all filters perform the same, but the size and type matter more than most realize.
• The right filter not only fits but works best for your specific HVAC, delivering long-term benefits.
The small extra effort to choose the right filter is a worthwhile investment that results in a healthier, more efficient, and cost-effective environment.

Frequently Asked Questions
Can I clean my furnace air filter instead of replacing it?
Yes, some washable filters can be cleaned and reused, but disposable filters should be replaced rather than cleaned.
Can air filters be washed and reused?
Yes, certain types of filters, specifically washable or reusable ones, can be cleaned and reused, while others are designed for one-time use only.
What are the symptoms of a dirty furnace filter?
Symptoms include reduced airflow, increased energy bills, frequent furnace cycling, strange noises, and poor indoor air quality.
What happens if you never change a furnace filter?
Neglecting to change can lead to decreased efficiency, increased energy costs, damage to the furnace, and poor indoor air quality due to accumulated dust and allergens.
How often should furnace filters be changed?
Furnace filters should generally be changed every 1 to 3 months, but this can vary based on filter type and usage conditions.
Which is better fiberglass or pleated furnace filter?
Pleated filters are typically better than fiberglass options as they capture more particles, have a higher efficiency rating, and last longer, improving indoor air quality.
