The Primary Effect Paper Frame Filter is a type of air filter designed to capture larger particles and contaminants from the air. This filter is commonly used in various HVAC (Heating, Ventilation, and Air Conditioning) systems to improve indoor air quality.

The filter's construction typically involves a frame made of paper or cardboard material. The paper frame provides structural support and stability to the filter, allowing it to fit securely within the filter housing of an air-handling unit. The filter media, often composed of fiberglass or other synthetic materials, is strategically arranged within the frame to create a barrier that captures particles as air passes through.

The primary purpose of this filter is to target larger particles such as dust, pollen, and lint. While it may not be as effective in capturing smaller particles when compared to more advanced filters like HEPA filters, it serves as an essential first line of defense in preventing larger contaminants from entering the HVAC system and circulating through the indoor environment.

Regular maintenance and replacement of Primary Effect Paper Frame Filters are crucial for optimal performance. Over time, these filters can become clogged with accumulated particles, reducing their efficiency and potentially compromising the airflow in the HVAC system.

In summary, the Primary Effect Paper Frame Filter is a foundational component in air filtration systems, providing an initial level of defense against larger airborne particles. Its affordability and widespread use make it a practical choice for improving air quality in various residential and commercial settings, especially when combined with other filters for comprehensive filtration.
