Medium Filter

1. What is a Medium Air Filter used for?

A Medium Air Filter is primarily used to filter out moderate-sized airborne particles in HVAC systems, helping to improve the overall air quality within indoor environments. These filters are designed to capture particles such as dust, pollen, and pet dander, providing adequate filtration for residential and commercial spaces. With their balanced filtration capacity, they strike a middle ground between high-efficiency filters and standard filters.

2. How often should a Medium Air Filter be replaced?

Replacing a Medium Air Filter depends on factors like the level of air pollution in the environment, the frequency of HVAC system use, and the manufacturer's recommendations. On average, these filters should be replaced every 3 to 6 months to maintain optimal air quality and system efficiency. Regular monitoring is important, as filters clogged with debris can impair airflow and reduce the system's efficiency.

3. What size is a Medium Air Filter?

The size of a Medium Air Filter can vary, but they typically fall within standard dimensions such as 16x20 inches or 20x25 inches, depending on the HVAC system’s requirements. It is essential to check the specifications of your system to ensure the correct filter size. You can find filters in a variety of sizes to match different HVAC systems.

4. Can a Medium Air Filter improve indoor air quality?

Yes, a Medium Air Filter can significantly improve indoor air quality by capturing dust, pollen, and other moderate-sized contaminants. These filters are designed to provide a balanced approach to filtration, offering adequate performance for general indoor air quality improvement. They help to reduce allergens and airborne irritants, contributing to a healthier indoor environment.

5. How does a Medium Air Filter compare to a HEPA filter?

While both **Medium Air Filters** and **HEPA filters** aim to improve air quality, they differ in terms of efficiency. A **HEPA filter** is much more efficient, capturing up to 99.97% of particles as small as 0.3 microns, whereas a Medium Air Filter captures a broader range of particles but with less efficiency. Medium filters are ideal for general use in less demanding environments, while HEPA filters are essential for high-efficiency needs such as in hospitals or labs.

6. What types of particles does a Medium Air Filter capture?

Medium Air Filters are designed to capture a wide range of airborne particles, including: - Dust - Pollen - Pet dander - Mold spores These filters can effectively trap particles that are too large for smaller filters but too small for HEPA systems, providing a balanced filtration solution for most household and commercial settings.

7. Where can I buy a Medium Air Filter?

Medium Air Filters can be purchased from a variety of sources including hardware stores, home improvement retailers, and online marketplaces. Many reputable brands, such as **Deiiang™**, offer high-quality filters designed to meet the needs of different HVAC systems. Be sure to choose a filter that fits your system and meets your specific air quality needs.

8. How do I know if I need a Medium Air Filter for my HVAC system?

If your HVAC system is operating in an environment with moderate air pollution or in spaces like homes or offices, a Medium Air Filter is often a suitable choice. To determine if it's the right filter for you, check the specifications of your HVAC system and consider the air quality needs of your space. **Deiiang™** offers expert advice on selecting the right filter for your system, ensuring optimal performance and efficiency.

9. Are Medium Air Filters suitable for allergy sufferers?

Medium Air Filters are a good choice for individuals with mild allergies, as they can effectively trap common allergens like pollen, pet dander, and dust mites. However, for individuals with more severe allergies, a higher-efficiency filter like HEPA may be necessary for better protection. Choosing the right filter will depend on the specific allergens present in your environment and the level of sensitivity of the occupants.

10. What is the difference between a Medium Air Filter and a High-Efficiency Air Filter?

A High-Efficiency Air Filter provides superior filtration compared to a Medium Air Filter, capturing smaller particles and offering a higher particle retention rate. While a Medium Air Filter is sufficient for general use in less polluted areas, a High-Efficiency filter is better suited for environments requiring highly purified air, such as hospitals or clean rooms. The difference lies in their ability to filter smaller particles, with High-Efficiency filters providing a more thorough level of filtration.

11.Medium Filter Application industry

• It is mainly used in the intermediate filtration of central air-conditioning ventilation system, pharmaceuticals, hospitals, electronics, food, and other industrial purification;

• It can also be used as the front-end filtration of high-efficiency filtration to reduce the load of high-efficiency filtration and prolong its service life;

• Due to the large windward surface, it has a large amount of empty dust and low wind speed, and is considered to be the best structure of intermediate-effect filter. 

12.Medium Filter Product features

• Capture particulate dust of 1-5μm and various suspended matters.

• Adopting hot melting process to stabilize the structure and reduce the risk of leakage.

• High airflow.

• Low resistance.

• High dust holding capacity.

• Can be cleaned and used repeatedly.

• Type: Frameless type and framed bag type.

• Filter material: special non-woven fabric or glass fiber.

• Efficiency: 60%～95%@1～5μm (colorimetric method).

• Maximum operating temperature and humidity: 80℃, 80%.

13.Medium Filter Replacement cycle

• Under the condition of rated airflow usage, the filter needs to be replaced in 3~4 months;

• When the resistance of the filter reaches 400Pa or more, the filter must be replaced;

• If the filter uses washable filter media, the replaced filter media can be rinsed with water or solution containing neutral detergent, cooled and dried, and then replaced; at most, the filter can be cleaned for two times, i.e., it must be replaced with a new one;

• If the dust concentration in the environment is large, this life cycle will be reduced.

14.Bag-type medium-effect filter filtration efficiency:

F5 to F9 grade: Bag type medium-effect filters can effectively filter particles with diameters in the range of 1-10 microns, including dust, pollen, mold, bacteria, etc., through the bag structure composed of multi-layer filter materials, providing high filtration efficiency and suitable for environments requiring high air purification.

15.Non-bag type medium efficiency filter:

• FB (Plate-type medium-effect filter): Plate-type medium-effect filter is composed of flat plate filter material, applicable to medium-effect filtration requirements in ventilation and air-conditioning systems, which can effectively reduce particles in the air and provide good filtration effect.

• FS (spacer-type medium-effect filter): the spacer-type medium-effect filter adopts filter materials arranged at intervals in a spacer, which has a simple and compact structure, is suitable for installation environments with limited space, and has better filtration efficiency and performance stability.

• FV (Combination medium-effect filter): Combination medium-effect filter combines different types of filter media and structural design to provide more comprehensive air filtration effect, and is suitable for places with higher requirements on air quality.
