Carter Electrostatic Filter INFO

Electrostatic air filters clean the air by using static electricity – a safe, naturally occurring phenomenon. An electrostatic charge is generated by air flowing through a maze of static prone fibers. Airborne particles are attracted and held by the static charge until released by washing. 

• Never needs replacing
• Cleaner air to breathe
• No harmful ozone emissions
• Reduces pollen, dust and airborne pollutants
• Reasonably priced
• Less housecleaning
• Anti-microbial filter media
• Limited Lifetime warranty
• High dust & particle holding capacity

 Carter Gold Frame filters are made with two layers of anti-microbial woven polypropylene, self-charging electrostatic fibers. Sandwiched in between those layers is one extra capacity polyester self-charging filter media for high capacity dust / contaminant retention. Then these layers are externally supported by an expanded metal mesh support. All of this is then housed in a premium quality extruded aluminum, gold anodized frame with a durable and attractive finish. These filters are designed to last a lifetime and hold a lifetime warranty to prove it. The frame is 4 separate pieces with a single screw fastening each corner together. The frame is strong and sturdy ideal for all applications. Gold Frame filters come only in the standard 1″ depth. 

 The air you breathe contains many irritants such as pollen, dust, bacteria, mold spores, pet dander and smoke. Most of these particles are smaller than ten microns. Your Carter filter is an effective and efficient way to reduce the number of these particles in your air.

 Arrestance is just a fancy word for filtering capacity. All carter filters come in one of two types of arrestance – either 94% or 88%. The 94% arrestance filter provides higher filtering capacity by trapping up to 94% of particles in the air. We also offer filters with an 88% arrestance. This provides slightly less filtering capacity, but is less restrictive, allowing greater airflow through the filter. An 88% arrestance filter would be appropriate using the following formula. If the filter square footage is less than the tonnage of the unit, we recommend an 88% arrestance filter. How To Determine If You Need an 88% or 94% Arrestance Filter Here’s an example: If you have a 16×25 filter and a 2.5 ton unit, the square footage of the filter is 2.8 sq feet (16 x 25 / 144 = 2.8). Since 2.8 is greater than 2.5, you are fine with using a 94% arrestance filter in this system. If the filter size is 12×18, the square footage of this filter is 1.5 (12 x 18 / 144 = 1.5). Since 1.5 is less than 2.5, we would recommend an 88% arrestance filter in this case. All 94% filters and the flexible frame 88% filters contain an EPA registered anti-microbial material to inhibit the mold and bacteria growth on the filter surface. 

 Every filter we manufacture is either a standard size or a custom size. The length and width of a standard size air filter is undercut by 3/8″ to accommodate standard size openings. This is consistent with other filter manufacturers. For example, if you are replacing a 25″ x 25″ disposable filter, then you need a standard size 25″ x 25″ electrostatic air filter. The actual size of this filter is actually 24 5/8″ x 24 5/8″. A custom size filter, however, is cut to the exact sizes you specify. So a custom size 25″ x 25″ filter will be exactly 25″ x 25″ – there is no undercut. The difference is very important – so if you have questions, please reach out
