Frequently Asked Questions

How often should I change my 20x25x1 air filter?

You should change your 20x25x1 air filter every 1 to 3 months, depending on your indoor air quality, pets, allergies, and HVAC system usage.

Is MERV 11 too high for residential?

MERV 11 is generally not too high for residential use and can be a great choice for improving air quality without overly restricting airflow in most systems.

Is MERV 14 too high for residential?

MERV 14 is typically too high for most residential HVAC systems and can restrict airflow unless the system is specifically designed to handle such dense filtration.

Is it better to use cheap or expensive air filters?

Expensive air filters often provide better filtration and last longer, but the best choice depends on your needs—such as allergies, pets, or dust levels—versus your system’s capabilities.

Is MERV 13 too high for home?

MERV 13 is near the upper limit for residential systems and is suitable if your HVAC can handle it, especially for homes with allergy sufferers or health concerns.

Are premium air filters worth it?

Premium air filters are worth it if you prioritize air quality and have specific health concerns or allergies, provided your system supports their airflow demands.

Is MERV 8 good enough?

MERV 8 is good enough for many households, capturing common airborne particles like dust and pollen without overly restricting airflow.

How much should a good air filter cost?

A good air filter typically costs between $10 and $30 depending on its size, MERV rating, and whether it includes features like odor control or antimicrobial treatment.

What are the disadvantages of a high flow air filter?

High flow air filters may allow more air through with less resistance, but they often sacrifice filtration efficiency, letting more contaminants circulate indoors.

Do carbon filters improve air quality?

Yes, carbon filters help improve air quality by trapping gases and odors that standard filters may miss, such as smoke, cooking smells, and VOCs.

Are the green AC filters good?

Green fiberglass AC filters are inexpensive and allow high airflow, but they offer minimal filtration and are generally not ideal for homes concerned with air quality.

What is the difference between FPR and MERV?

FPR (Filter Performance Rating) is Home Depot’s proprietary system that loosely corresponds to MERV ratings but is less standardized and not as widely used.
