Key Benefits of Filtedeg Fiberglass Air Filters
Fiberglass Air Filters have many advantages. We can customize a variety of structural sizes according to your needs in different scenarios

The fluffy glass fiber structure can effectively reduce wind resistance, which is more suitable for HVAC equipment with air volume requirements. The lower resistance helps reduce the load on the fan and keeps the system running steadily.

The density reduction structure of Fiberglass HVAC Filter from sparse to dense is that particles of different sizes are distributed at different depths of the Filter material, which is not easy to cause blockage and can fully use the dust capacity.

Fiberglass Air Filters have a variety of choices such as mesh surface, metal support, paper frame support, dispensing support, etc. on the border and supportable mesh selection, which can provide effective support for fluffy glass fiber filter material and prevent Air filter displacement or deformation.

Filter material and frame directly We adopt continuous bonding and sealing design, which can prevent the possibility of edge air bypassing the filter material and help the air filter better fit the mounting slot.

Fiberglass Air Filter Applications
Filtedge glass fiber air filter is widely used in commercial buildings, industrial plants, warehousing and logistics, residential heaters and other multi-stage filtration systems. It can effectively intercept large dust, hair and fibers, protect fans and coils, and effectively reduce energy consumption and operating cost
If you need to purchase air conditioning systems for office buildings, hotels, schools, and shopping malls, then Filtedge fiberglass air filters can be used as primary air filtration products to help you protect fans, coils and heat exchangers, etc. The commonly used sizes are generally 1 inch and 2 inch
In industrial plants, problems such as excessive dust in the workshop, frequent dust accumulation in equipment, increased energy consumption, etc. may increase your production cost and affect your EIA. Filtedeg Glass Fiber Air Filter has some excellent characteristics, fluffy Fiber gradient, high dust capacity and low wind resistance, which can help you increase the dust capacity. Under normal working conditions, its life is up to 6-12 months, which reduces consumables and maintenance costs by more than 30% for you. It can also effectively protect the back-end Air Filter, so that the overall energy consumption of the ventilation system in the factory can be reduced by 10%-15%, and the energy-saving benefits of long-term operation are remarkable.
Fiberglass Air Filter Specifications
Fiberglass air filters are mainly used to trap hair, batting, fibers and larger dust particles to reduce the accumulation of pollutants in fans, coils and equipment.

You will need the following information when purchasing:
- Test standards adopted
- Test Air Volume and Windward Wind Speed
- Product size and thickness
- Initial resistance in test state
Filtede can select the appropriate filter material and structure according to your needs, and the final MERV grade should be subject to the test report of the specific model.
There is no definite replacement cycle for fiberglass air filters, which is determined by the following factors:
- HVAC system running time
- Dust concentration
- Filtration area of filter
- System rated air volume and onward wind speed
- Initial and final resistance of the filter
The normal condition of the cycle that needs to be replaced is as follows:
- Regular shopping malls usually take 6-12 months
- High dust environment usually takes 3-6 months
- Clean scenes typically take 18-24 months
Any air filter will have air resistance, which is inevitable. However, the airflow resistance of glass fiber filter is extremely low, and its material is fluffy, which has a relatively low impact on the system air volume. Generally, the airflow of the plate air filter and the non-folding structure is relatively smooth, but if it is not replaced for a long time, it will cause blockage and the resistance will gradually increase. Therefore, not only to choose the right Fiberglass AC Filter, you also need to maintain it regularly.
Glass fiber air filters are usually less resistant and economical, while folding air filters have a larger filtration area. They differ as follows:
| Compare Items | Fiberglass Air Filter | Folding Air Filter
|
| Structure | Loose type | folded type |
| Filter Grades | Common MERV1 – MERV4 | Common MERV8 – MERV13
|
| Initial resistance | usually lower | higher |
| Filtration area | smaller | larger
|
| Fine particle filtration capacity | Limited | Good |
| Dust Holding Capacity | Low | Relatively High |
| Main Application | Equipment protection,pre-filter | Fine filtration |
Fiberglass air filter has a variety of borders to choose from including: kraft cardboard, moisture-proof cardboard, plastic, galvanized steel and aluminum, etc. You can choose the right material according to your working conditions.
- Kraft paper border
Light weight, low cost, suitable for commercial HVAC, cannot be used in humid and corrosive environments. - Moisture-proof paper frame
It has better moisture resistance than kraft paper, and is suitable for environments with humidity but no moisture condensation. - Plastic border
Compared with kraft paper frame and moisture-proof paper frame, it is moisture-resistant, but cannot be used in high-temperature environment, and has the advantage of stable structure. - Galvanized steel frame
Galvanized anti-rust, high mechanical strength, suitable for more commercial HVAC systems, can operate in high air volume environment - Aluminum frame
Lightweight, corrosion-resistant, moisture-resistant, generally used in precision equipment environment, its price is more expensive than paper-framed glass fiber air filter.
