Finding Your Perfect Purolator Filter Fit

To identify the ideal Purolator filter for your HVAC setup, follow these steps:

Examine your existing filter: Look for size information printed on the frame of your current filter.
Take precise measurements: If size details aren't visible, use a tape measure to determine the length, width, and depth of your filter slot.
Explore upgrade options: Purolator offers filters of varying thicknesses. Your system may be compatible with a thicker filter, potentially enhancing filtration and reducing replacement frequency.
Utilize Purolator's resources: Browse through our detailed size charts to pinpoint the exact filter that matches your system's requirements.
Seek expert advice: If you're uncertain, reach out to a qualified HVAC professional or a Purolator expert to ensure you select the most suitable filter size and type for your particular system.

Understanding Purolator's MERV Scale

Purolator's comprehensive filter lineup includes options with MERV (Minimum Efficiency Reporting Value) ratings ranging from 8 to 15.

This broad spectrum caters to diverse needs, from basic residential filtration to more demanding commercial and industrial applications, offering superior air purification without compromising system airflow.

MERV 8-10 filters: Suitable for general household use, effectively trapping larger particles like dust, pollen, mold spores, and pet dander. These filters provide a good balance between filtration and airflow, making them ideal for most residential HVAC systems.

MERV 11-13 filters: Ideal for homes with allergy sufferers and light commercial spaces. These filters capture smaller particles such as fine dust, smoke, and bacteria, providing enhanced air quality without significantly impacting system performance.

MERV 14-15 filters: Designed for more demanding environments like hospitals, laboratories, and industrial settings. These high-efficiency filters can trap microscopic particles, including some viruses and odor-causing molecules, offering superior air purification for sensitive environments.

Purolator's attention to filter media ensures optimal efficiency and performance across all MERV ratings. As you move up the MERV scale, filtration efficiency increases, but it's important to consider your specific needs and system capabilities when selecting a filter.

Higher MERV ratings may require more frequent changes and could potentially impact airflow in some systems not designed for high-efficiency filtration.

Regardless of the MERV rating you choose, Purolator's commitment to quality ensures that you're getting a filter that balances effective particle capture with optimal system performance.

Always consult with an HVAC professional or Purolator representative to determine the best MERV rating for your specific application and system capabilities.
