Anping County Boli Hardware Wiremesh Products Factory, established in 1998, brings over two decades of manufacturing expertise to the HVAC filtration industry. Our HEPA Pre-filter for HVAC Systems (24x24x2, MERV 8, 80% Efficiency) is designed to drastically reduce dust and pollen in commercial buildings, offering a cost-effective solution that extends the life of your main HEPA filters. With annual export values exceeding US$5 million and shipments to major global markets including North America, Europe, and Southeast Asia, our factory in Hengshui, Hebei, China delivers consistent quality and reliable performance.
This pre-filter acts as the first line of defense in your HVAC system, capturing larger airborne particles before they reach the main filter. Its MERV 8 rating ensures 80% efficiency on particles between 3 and 10 microns, including common allergens like pollen, dust mites, and mold spores. The 24x24x2 inch size fits standard commercial HVAC racks, making replacement quick and hassle-free. Backed by a 1-year warranty, this filter is built to withstand continuous operation in demanding environments such as office buildings, hospitals, schools, and retail centers.
- High Dust-Holding Capacity: The pleated design increases surface area, allowing the filter to trap more dust without clogging prematurely.
- Low Air Resistance: Optimized media density minimizes pressure drop, saving energy and reducing strain on HVAC blowers.
- Moisture-Resistant Frame: Optional galvanized steel frame resists warping in humid conditions, while the standard cardboard frame is suitable for dry indoor use.
- Easy Installation: Lightweight and flexible design slides easily into standard 24x24-inch filter slots.
- Environmentally Friendly: Disposable and recyclable materials reduce waste (check local recycling guidelines).
- Consistent Performance: Each filter is manufactured under strict quality control to ensure uniform pleat spacing and media integrity.

Our HEPA Pre-filter is specifically engineered to protect downstream HEPA filters and improve overall indoor air quality. By capturing bulk dust and pollen, it reduces the load on the final filter, extending its service life by up to 50%. This translates to lower maintenance costs and fewer filter changes for facility managers. The pleated construction also ensures consistent airflow even as the filter loads, preventing sudden spikes in static pressure that could disrupt HVAC system balance.
For commercial buildings, maintaining a healthy indoor environment is critical. Our MERV 8 pre-filter effectively removes common allergens, reducing the risk of respiratory issues among occupants. It is also an economical choice compared to higher-grade filters, making it ideal for large-scale applications where thousands of filters are needed annually. The 24x24x2 size is one of the most popular dimensions in the industry, ensuring compatibility with existing filter racks from major manufacturers.
As a manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory has shipped US$5-10 million worth of products annually to clients across North America, South America, Europe, and Asia.

Frequently Asked Questions (FAQ)
-
Q: Is this filter a true HEPA filter?
A: No, this is a MERV 8 pre-filter, not a HEPA filter. HEPA filters typically have a MERV 17 or higher rating. This pre-filter is designed to capture larger particles and protect the main HEPA filter, extending its life. -
Q: What is the actual efficiency of this filter?
A: The filter has an 80% efficiency on particles between 3 and 10 microns (based on ASHRAE 52.2 testing). It is less effective on smaller particles, but it excels at capturing dust, pollen, and mold spores. -
Q: Can this filter be used in residential HVAC systems?
A: Yes, the 24x24x2 size is also common in residential systems, but it is primarily designed for commercial use. Check your system's filter slot dimensions before purchasing. -
Q: How often should I replace this filter?
A: Under normal commercial conditions, replacement every 3-6 months is recommended. In high-dust environments or during peak pollen seasons, more frequent replacement may be needed. -
Q: Is the frame made of metal or cardboard?
A: The standard frame is corrugated cardboard. A galvanized steel frame is available as an option for environments with high humidity or where extra durability is required. -
Q: Does this filter come with a warranty?
A: Yes, it comes with a 1-year warranty against manufacturing defects. Contact us for the full warranty terms. -
Q: Can I get custom sizes or packaging?
A: Yes, we offer customization on size, frame material, label, and packaging. Minimum order quantities may apply. Please inquire with our sales team. -
