🛠 What We See All the Time (And Fix)
Our team services hundreds of HVAC systems yearly. These are the most common mistakes we fix:
Wrong filter size (e.g., using a 1" instead of a 2")
Incorrect MERV rating – too low for air quality needs, or too high for system airflow
Infrequent replacements – leading to clogged filters and overworked systems
Poor fit/seal, letting unfiltered air bypass the system
When corrected, homeowners see:
Better airflow
Less dust
Lower humidity indoors
Quieter HVAC operation

Our Pro Tip
Not all filter upgrades are equal.
Wrong size or MERV rating? You could reduce airflow instead of improving it.
We always recommend pairing a filter upgrade with a quick airflow evaluation.
That’s how you turn a basic air filter swap into a smart, system-wide upgrade.
Bottom Line
A high-efficiency 20x25x2 filter is one of the simplest, most cost-effective upgrades you can make—for your air, your comfort, and your wallet.
Next Steps: What to Do Now
Ready to improve your indoor air and HVAC performance? Follow these simple steps:
1. Check Your Current Filter
Look for the size (should say 20x25x2)
Confirm MERV rating (ideally MERV 11–13)
Not sure? Take a photo and ask your HVAC tech
2. Choose the Right Filter
Select a high-efficiency MERV 11–13 filter
Pick trusted brands with good airflow ratings
Consider allergen or odor-reducing options if needed
3. Install It Properly
Match airflow arrows with your system
Ensure a snug, gap-free fit
If your system struggles after install, airflow may need balancing
4. Set a Reminder
2” filters last 3–6 months
Add a calendar alert or set up auto-delivery
5. Schedule a System Check
Especially helpful if you're upgrading from a 1” filter
Ensures your system handles airflow efficiently
Can prevent short cycling and early wear

Frequently Asked Questions
How often should I replace my 20x25x5 air filter?
You should replace your 20x25x5 air filter every 3 to 6 months, but check it monthly for dirt and debris, especially if you have pets or live in a dusty area.
What is the best MERV rating on air filters?
The best MERV rating for general home use is typically between 8 and 12, as these filters effectively capture allergens without significantly restricting airflow.
What is the best filtration level for an air filter?
The best filtration level depends on your specific needs, but a MERV rating of 8 to 11 is often ideal for balancing air quality and system efficiency in residential settings.
Can a high MERV filter damage my furnace?
Yes, a high MERV filter can restrict airflow and potentially damage your furnace if it's not designed to handle such filters, leading to overheating and increased wear.
Do pleated air filters restrict airflow?
Pleated air filters can restrict airflow more than flat filters, but they are generally designed to maintain adequate airflow while providing better filtration.
Is MERV 8 or 11 better?
MERV 11 is better than MERV 8 in terms of filtration efficiency, as it captures smaller particles, making it more effective for improving indoor air quality.
