Know before you buy
The nominal size of 18x18x1 is the industry-standard label used for shopping, while the actual dimensions are 17 11/16’’ x 17 11/16’’ x 3/4’’. Always measure your current filter or housing slot to ensure the actual size fits your specific HVAC system.
While MERV 13 filters are denser than lower-rated options, this model is engineered for low airflow resistance. However, if your system is older or has weak blower motors, you should monitor your system's performance after installation to ensure it maintains proper circulation.
For optimal air quality and to prevent strain on your HVAC system, we recommend replacing these filters every three months. If you live in a home with pets, high dust levels, or frequent smoke, you may need to check them sooner.
A MERV 13 rating is highly effective at capturing 93% of airborne particles, including virus carriers, bacteria, smoke, pollen, pet dander, and mold spores. It provides a significant upgrade over standard filters, making it a great choice for households concerned with indoor air quality.
Yes, this filter is comparable to MPR 1500-1900 and FPR 10 ratings. You can use it as a direct replacement if your current system calls for those performance levels.
