Are You Using the Right Size? 16x28x4 Aprilaire HVAC Furnace Replacement Air Filters vs. 16x16x1
Selecting an appropriate HVAC air filter exceeds the basic task of selecting filter dimensions. Through my experience working with multiple homeowners, I have witnessed how suitable air filters directly affect system efficiency together with indoor air quality.
In this guide, I’ll break down the differences between two popular options—16x28x4 Aprilaire filters and 16x16x1 filters—by sharing my experience and insights. I’ll not only explain how each size and MERV rating affects filtration performance but also highlight practical considerations based on real-world usage.
Top Takeaways
1️⃣ Right Filter = Better Air Quality:
• Choose the correct size and MERV rating for improved filtration.
2️⃣ Higher MERV = More Particles Removed:
• MERV 13+ filters capture more allergens, dust, and pollutants.
3️⃣ Change Filters Regularly:
• Replace every 1-3 months to maintain system efficiency.
4️⃣ Tailor Filter Choice to Your Needs:
• Consider allergies, pets, and local conditions.
5️⃣ Long-Term Savings:
• Upgrading filters improves performance and reduces energy costs.
Case Study: Real-World Impact of Filter Size and MERV Rating
A family in Palm Beach County was dealing with persistent allergy symptoms, despite regular filter changes.
• They were using 16x16x1 filters.
• The filters were too small and lacked sufficient filtration for Florida’s high humidity.
Results:
✔️ Within weeks, allergy symptoms significantly decreased.
✔️ The air quality improved, and the HVAC system ran more efficiently.
✔️ The larger filter reduced system strain, extending the HVAC’s lifespan.
Another Example: Miami Homeowner’s HVAC Efficiency
A homeowner in Miami was using a 16x16x1 filter with a low MERV rating.
• High traffic areas with dust and pollutants.
• The HVAC system was inefficient, with frequent breakdowns and high energy bills.
Results:
✔️ The new filter captured more dust and allergens.
✔️ The HVAC system became more efficient, reducing energy costs and repairs.
✔️ The homeowner noticed better air quality and fewer system issues.
The right air filter isn’t just about size—it’s about matching the filter to your home’s specific needs for optimal air quality and HVAC performance.
"From my years of hands-on experience, I've seen firsthand how the right filter can transform both air quality and system efficiency. It's not just about fitting a filter into your system—it's about choosing the right size and MERV rating to meet your home's unique needs. In my experience, this thoughtful approach can reduce allergy symptoms, improve system performance, and save homeowners money in the long run."
Supporting Statistics: The Impact of Filter Choice
Selecting the right HVAC furnace filter is critical. Here’s what the research says:
ASHRAE Insights
• Filter performance varies based on home factors like leakage, air circulation, and climate.
• A one-size-fits-all approach doesn’t work—tailor filter choice to your specific conditions.
• (ashrae.org)
EPA Recommendations
• MERV 11 filters remove about 20% of particles between 0.3 and 1 micron.
• MERV 13 filters capture up to 50% of these tiny particles, improving air quality.
• (epa.gov)
CDC Guidance
• MERV filters help remove airborne particles, including viruses and bacteria.
• Upgrading to higher-rated filters can enhance health and reduce system strain.

Final Thought & Opinion: The Importance of Choosing the Right Filter
Selecting the right filter is more than just a convenience—it’s essential for your health and the system’s efficiency. Here’s why:
• The right filter can make a noticeable difference for allergy sufferers.
• A properly sized and rated filter helps your HVAC system run smoothly, reducing strain.
• Cleaner filters mean fewer repairs and lower energy costs.
From My Experience
• I’ve seen families experience significant allergy relief just by switching to a higher MERV filter.
• Homeowners have saved money on energy bills and avoided costly repairs by upgrading their filters.
Key Insights
• Upgrading your filter may come with an initial cost, but it offers long-term benefits.
• Choose a filter based on your home’s unique needs to improve air quality and HVAC performance.
Next Steps: How to Choose the Right Filter

✔️ Consider allergies, pets, and local conditions (humidity, pollution).
✔️ Check your HVAC system’s manual for filter size.
2️⃣ Choose the Right Size
✔️ Ensure the air filter size matches your system’s specifications.
✔️ Common sizes are 16x16x1 and 16x28x4.
3️⃣ Pick the Correct Rating
✔️ MERV 8-11 for general air quality.
✔️ MERV 13+ for allergies or respiratory issues.
4️⃣ Upgrade Your Filter
✔️ Buy from a trusted supplier.
✔️ Consult an HVAC professional if unsure.
5️⃣ Maintain Your System
✔️ Change the filter every 1-3 months.
✔️ Schedule annual HVAC maintenance.
Keep your HVAC system running efficiently!
Frequently Asked Questions
Do you really need to change the furnace filter every 3 months?
Yes, changing every three months is recommended to maintain efficient airflow and improve indoor air quality.
Does MERV 11 restrict airflow?
MERV 11 air filters impose reduced airflow compared to lower-rated alternatives although residential heating systems usually work fine using this level of filtration.
How do you restart the furnace after changing the filter?
The process of restart begins with turning off the power while replacing the filter after turning it back on. After setting the thermostat at the desired temperature restore the system operations.
Is no furnace filter better than a dirty one?
No, using no filter can cause dust and debris to accumulate in the furnace, leading to potential damage and reduced efficiency, while a dirty filter can restrict airflow.
What happens if you wait too long to change filters?
Waiting too long can lead to reduced airflow, and increased energy costs, and may result in the furnace overheating or breaking down.
What is the best MERV rating for an old furnace?
A rating of 8 to 10 is generally considered best, as it balances filtration efficiency with airflow capacity without overly restricting it.
