Custom Filters Direct 14×17.5×1 air filters provide high-quality air filtration for homes and businesses. With premium quality materials, moisture-resistant frames, and synthetic filtration media, our air filters are highly efficient at capturing more than 90% of harmful particles in the air.

Our air filters maintain excellent airflow, provide exceptional working performance, and have a maximum dust holding capacity. All these qualities make our air filters a superior choice for residential and commercial air filter needs. 14×17.5×1 air filters not only remove most microscopic particles but also neutralize even the strongest odors. These filters will eliminate smells associated with food products, alcohol, sewers, cooking, and more.

All our air filters are proudly made in the USA and are ergonomically designed to capture and absorb harmful particles from the air. Though our custom air filters are designed to last long, we recommend you to check the filters regularly. Once these filters are clogged, they are unable to allow proper airflow to pass through. The lack of airflow leads to health problems like breathing issues. That’s why we suggest you change your air filters every 2-3 months to maintain healthy indoor air quality.

Custom Filters Direct 14×17.5×1 air filters are available in 3 different MERV ratings –


These air filters trap most of the airborne particles sized 3 to 10 microns. These are filters are ideal to use in homes to trap dust, pollen, mold, and bacteria.


These air filters are more efficient than MERV 8 as they trap most smaller particles from the air stream. MERV 11 filters will trap more than 85% of air particles 3.0-10.0 microns in size and 50% of air particles 3.0-10.0 microns in size. These filters are ideal for households with pets or babies.


These filters specialize in trapping more than 90% of airborne allergens sized between 3 to 10 microns and will also be effective to remove up to 75% of harmful contaminants sized 0.3 to 1 micron. Unlike MERV 8 and MERV 11, these AC and furnace filters also trap tobacco smoke, smoke from fires, pollutants in bodily fluids released through sneezing and coughing, and bacteria.
