Custom Filters Direct 12x18x1A air filters are commonly used in home and commercial HVAC systems to eliminate dust particles from entering via airflow. Designed for both residential and commercial spaces, these filters are engineered for sturdy, economical performance, and ease of use. With 100% synthetic filter media, these air filters greatly improve clean airflow while eliminating very small particles that can irritate your lungs. Better airflow means your HVAC doesn’t have to work as hard and will heat or cool your home or office in less time and at a lower energy cost.
Our 12x18x1A air filters are designed to fit into almost any HVAC system and serve as a protective layer against irritants and allergens. However, it is necessary to check your air filters regularly and replace them every 3-4 months.
Though these air filters are fabricated for better airflow and longer-lasting air filtration, eventually dirty particles accumulate on the filter surface, resulting in a poor level of filtration. Therefore, it is necessary to replace your filter frequently depending on the factors like health issues, environmental challenges, and more.
The MERV rating indicates how well the filter can remove contaminants and particulate matter from the air. The higher the MERV, the more efficient the HVAC filter is. At Custom Filters Direct, we offer 12x18x1A HVAC filters in MERV 8, 11, and 13 ratings.
MERV 8 air filters will capture 85% of common allergy particles like pet dander and dust mites.
These MERV 11 air filters will capture more than 85% of 3.0 – 10.0 micron size particles. This air filter is a great choice if you or someone in your home has moderate allergies. For more serious or severe allergies, we suggest a MERV 13 rating.
MERV 13-rated AC and furnace air filters come with more than 90% efficiency to capture 3.0 – 10.0 microns size particles. In addition to that, these will collect very smaller particles between 0.3-1.0 microns in size.
Whether you need a single 12x18x1A AC and furnace air filter or a set of four or more, we have what you need at a great price. You can save money when ordering air filters in bulk. You can choose from different MERV ratings, and you can buy one filter at a time or multiple air filters from the comfort of your home.
