Accumulair® Gold is an air filter designed with better air quality and higher filtration efficiency in mind. It is given an APR 650 filter rating, which means that it is a medium-efficiency filter that removes airborne particles smaller than 1 micron. This means that it removes a large variety of indoor air pollutants, including dust mites, bacteria, mold spores, pet dander, pollen, lint, and smoke.

Unlike regular fiberglass filters, the Accumulair® Gold filter uses electrostatic filtration, which is a special filtration media that uses an electric charge to attract and trap air particles. With a dust spot efficiency of 30-35%, the Accumulair® Gold filter removes 20 times more particles than ordinary fiberglass filters. Even with high particulate efficiency, it manages to maintain low resistance to airflow. Accumulair® Gold filters are available in many different sizes, but they can also be custom made to fit any desired filter system.

Construction:

• 100% synthetic media
• Pleated shape
• Hydrophobic fibers
• Does not support microbial growth
• Recyclable, galvanized, corrosion resistant metal backing
• 2-piece heavy duty die cut frame

The construction of the Accumulair® Gold filter is vital to the filter^TMs performance and durability. It is constructed of 100% synthetic material that provides excellent particulate efficiency with relatively low resistance to airflow. The uniform pleated shape is intentionally designed to maximize airflow and to enhance particle holding capacity. This filter media is made chemical free, so it does not pose threats of contaminating household air. Also, composed of hydrophobic fibers, this filter does not support the growth of microbes like bacteria, mold, mildew, or fungi.

The pleated filter media is laminated to a steel support that helps prevent bending and warping of the filter from pressure as air moves through the filter. The filter is then bonded to the inside of a heavy duty board frame. This two-piece, die cut frame is constructed of a heavy duty, moisture resistant, clay coated board and is designed with horizontal and diagonal grid supports to add to the durability and output of this filter.

How It Works:

Accumulair® Gold filters use electrostatic filtration, which is a special filtration media that is designed to provide higher efficiency filtration. All regular fiberglass filters remove air pollutants from air circulating inside, but they only manage to capture the bare minimum. Electrostatic filters, such as the Accumulair® Gold filters, take filtration to an extra step. As air circulates through the HVAC system, it passes through the electrostatic filter. The electrostatically charged fibers work like tiny magnets to trap the oppositely charged air particles, leaving purified air circulating throughout the house.

Accumulair® Gold filters can be installed in existing filter systems, usually without any necessary modifications. Though Accumulair® Gold filters are often used as a primary filter, they can also serve as a pre-filter for more expensive, higher efficiency filters in industrial and commercial agencies (i.e. hospitals, plants, schools, office buildings, etc.).

Accumulair® Gold filters typically last about three months, but their filter life depends on several factors. Air quality, rate of airflow, types of allergens, and other factors all contribute to the length of filter life. However, for maximum filtration output, it is important to keep the filters replaced regularly because particles begin to build up around the electrostatic fibers,
resulting in lower efficiency.

Accumulair® Gold Removes:

• Dust particles
• Dust mites
• Bacteria
• Mold spores
• Pet dander
• Tobacco smoke
• Pollen grains
• Lint, dirt, debris, etc.

Ideal For:

• Anyone with poor to medium air quality
• Anyone looking for better air quality for home, work, or school
• Anyone who needs pre-filtration for higher efficiency systems
