Custom Filters Direct 16.5x21x1 air filters are one of the most efficient filters available on the market. Our air filters will capture more than 90% of airborne allergens such as pollen, mold spores, fine dust, pet dander, and particles that carry viruses and bacteria. 16.5x21x1 air filters not only remove the unwanted allergens but also minimize system back pressure and keep the airflow clean and fresh.
Custom Filters Direct 16.5x21x1 air filters are made to perfectly fit your home or office HVAC unit. Our air filters come with a heavy-duty beverage board frame that stands up to rough and difficult conditions while providing long-lasting results. Though our filters are long-lasting, it is recommended to check them regularly and replace them once they become dirty.
Our air filters offer unmatched dust-holding capacity. However, you need to make sure you replace the air filters every 2-3 months. Replacing your air filters on time will not just help you maintain healthy indoor air quality, but also save on costly HVAC repairs.
MERV 8 AC and furnace air filters can provide superior filtration as compared to cheap air flyers available on the market. Our MERV 8 filters will capture 85% of the airborne particles to keep the indoor air of your home or office clean.
MERV 11 air filters are more efficient at eliminating particles than MERV 8 filters. Choosing MERV 11 filters will help you eliminate more than 85% of the airborne particles 3.0-10.0 microns in size, and 50% of the particles 1.0-3.0 microns in size.
MERV 13 AC and furnace filters are even superior to MERV 8 and MERV 11 filters. We recommend using MERV 13 air filters for hospitals, high-end restaurants, healthcare facilities, and other places where superior air filtration is required.
