Advantages of Washable Pre Filter

Environment-friendly: Most conventional air filters are usually made of cardboard frames, metal mesh, and fiberglass. The process of recycling these materials is very challenging, and it will take a lot of time to separate them for the local recycling center.

Money saving: The main problem with the other filters is that you need to change them almost every 6 weeks or 90 days; this will make you spend money on new filters more frequently. One of the main advantages of reusable filters is cost savings. Their long lifespan means fewer frequent replacements, leading to lower overall expenses.

Time-saving: When your disposable filters expire and you need to buy a new one, it takes your precious time, and you will do this every 3 to 6 months. Purchasing a new filter can be challenging because you will spend a lot of time trying to find a perfect-size filter that can properly fit into your HVAC system.

Improved air quality: The washable or reusable air filters improve indoor air quality by capturing airborne particles like dirt and dust. These filters are effective in removing large particles of size more than 10 microns.

Features of Washable Pre Filter

Primary Efficiency Washable Plate Filter

Outer frame

Constructed from metal (such as aluminum alloy, galvanized steel) to form a solid frame ensuring the filter media remains stable and resists deformation after cleaning.

Filter material

Made of synthetic fiber, laid in the outer frame in a flat shape, some models are covered with metal mesh or plastic mesh to enhance protection.

Washable design

The filter material is water-resistant and chemically resistant, allowing dust removal through washing, compressed air blowing, or soaking in a neutral detergent solution- restoring filtration performance.

Application of Washable Pre Filter

Central air conditioning ventilation system

Washable pleated filter is used as a primary filter and installed at the air inlet of the HVAC unit to filter out pollutants such as dust, hair, and pollen in the air, thereby protecting subsequent medium and high efficiency filters and equipment, and effectively reducing operating costs.

Industrial pre-filtration

In clean workshops in the electronics, food, pharmaceutical and other industries, it is used as a pre-filter device for HEPA filters to extend the service life of the terminal filter; Installed at the inlet of industrial exhaust treatment systems, it effectively reduces large-particle dust abrasion on equipment.

Commercial and civil applications

Suitable for centralized ventilation systems in office buildings, shopping malls, and hospitals; some models are also suitable for home air purifiers, computer room air conditioners, laboratory fume hoods where moderate air purification is required.

Production Process of Washable Pre Filter

The process begins with the preparation of filter media, typically made from ultra-fine glass fibers or synthetic materials, which are arranged into a dense, randomly oriented mat. This material is then pleated to maximize the surface area and enhance airflow efficiency.

The pleated media is carefully inserted into a sturdy frame, often made of metal or high-strength plastic, which provides structural integrity. The frame is sealed with adhesives or gaskets to ensure a tight fit and prevent air leakage.

Quality control tests, including efficiency evaluations and particle retention tests, are conducted to confirm the filter's ability to capture at least 99.97% of airborne particles as small as 0.3 microns.

FAQ

Q: What is the use of pre-filter?

A: The primary purpose is to collect large dust particles, pet fur, and pollutants and preserve the HEPA filter and extend its lifespan.

Q: Can you wash any pre-filter?

A: No, not at all. In particular, you must not wash pre-filters that are combined with a carbon or HEPA filter.

Q: How long do the pre-filters last?

A: If the pre-filter is combined with a carbon or HEPA filter, it is entirely replaced with other filters. However, washable filters should rarely be changed, except when some significant physical damage occurs.

Q: Is pre-filter necessary?

A: In my opinion, it is, primarily if you have pets. But even if you don’t have them, the pre-filter will definitely extend the life of the HEPA filter.

Q: How often do you have to clean the pre-filter?

A: It is generally advised to clean the pre-filter on average between 2-4 weeks. It is optimal once a month. If you notice that the pre-filter gets dirty quickly, you can clean it more often. Or if it doesn’t get dirty much, it doesn’t need to be cleaned as often.
