What Role These Filters Play
In most air handling units and small HVAC systems, you need a simple, inexpensive, and easy-to-replace first-stage filter.
These disposable panel filters are located at the front of the system and:
•Catch fibers, lint, hair, and coarse dust
•Keep coils and fan wheels cleaner for longer
•Reduce the load on any F5–F9 or HEPA filters installed downstream
They are not "high-tech" parts of the system, but they are often the ones you buy and replace the most. Our factory's responsibility is to manufacture these everyday consumables with consistent specifications and reliable delivery, making it convenient for you to stock them long-term and use them in your projects.
Typical Uses – Where Buyers Put Them
Based on the projects we are currently shipping, this type of panel filter is mainly found in several types of systems：
Commercial and light industrial AHUs
As the first pre-filter stage in office buildings, shopping centres, hospitals and small factories, usually in standard modular sizes.
Rooftop and package units
Used as quick-change filters in rooftop units and packaged AC units where service teams want something that can be swapped in minutes.
Residential and light commercial furnaces / AC systems
As simple HVAC panel filters or "furnace filters" in common inch sizes, especially in markets where end-users expect a low-cost, replaceable filter.
Temporary or rental equipment
On rental air handlers or dehumidifiers where the filter is replaced at every job and cost control is important.
How the Filter Is Put Together
We only present the facts and clearly explain the structure, making it convenient for engineers and procurement personnel to compare and contrast:
Media Options
Fiberglass media – the classic blue/white type, a traditional solution used for decades, suitable for simple pre-filtration.
Synthetic non-woven – made of polyester or similar fibers, more durable than fiberglass, produces less lint, and performs more stably in high-humidity environments.
Frame types
Moisture-resistant recycled cardboard for standard HVAC use.
Galvanized steel or aluminium frames for rough handling or where cardboard is not acceptable.
All frames designed to fit common filter tracks or simple holding frames.
Support & sealing
Expanded metal or plastic mesh on at least one side to keep the media flat
Media bonded to the frame on all four sides to minimise bypass
Gasket strip can be added on request if your housing has tighter leakage requirements
How the Filter Is Put Together
• Efficiency:
•Coarse grades roughly G2–G4 Approx. MERV 6–8, depending on media and thickness
• Media: Hydrophobic synthetic fiber or glass fiber (resistant to moisture and mold) .
• Frame Options: Reinforced cardboard, galvanized steel, or recyclable plastic.
• Dimensions: Standard sizes (e.g., 20x20x1", 24x24x4") + full customization support.
• Lifespan: 3-6 months (varies with air quality).
We specialize in small MOQs, ODM/OEM services, and logo imprinting to meet niche market demands.
Choosing Media & Thickness for Your Market
When manufacturing these disposable panel filters, practices vary significantly across different countries and distribution channels. We typically discuss two options with you first: the filter media and the thickness.
5.1 Fiberglass vs. Synthetic
Fiberglass
•Lower cost, commonly used in many older projects and according to local standards.
•Lower resistance, suitable for applications sensitive to energy consumption but not sensitive to fiber shedding.
Synthetic non-woven
•Better moisture resistance, more stable in high-humidity or frequently starting/stopping systems.
•Less fiber shedding, preferred by processes sensitive to particulate matter.
5.2 1" vs. 2" Thickness
1" thickness
•Widest compatibility, most existing furnaces and small AHU filter frames are made to this size.
•Slightly higher replacement frequency.
2" thickness
•Lower resistance and higher dust holding capacity at the same airflow.
•Suitable for systems that allow for thicker filters and want to extend replacement cycles.
You tell us your target market, common unit types, and main distribution channels (engineering/OEM/retail/e-commerce), and we will configure the media and thickness according to end-user habits, rather than simply assuming "thicker is better" or "higher grade is better."
How We Supply Disposable Panel Filters to You
From a purchasing or brand operations perspective, we generally offer three modes of cooperation:
Project-based batch supply
Production scheduled according to project specifications
Outer packaging can be marked with project number, floor number, and unit number
Facilitating distribution by construction or maintenance teams by area
Long-term stock of standard specifications
Selecting a core set of sizes and specifications (e.g., 20×20×1, 20×25×1, 24×24×2, etc.)
Creating fixed material numbers for your company
Placing orders on a rolling quarterly/annual basis to reduce stock shortages and frequent design changes.
OEM / Private Label
Outer packaging and labels designed according to your brand
Your logo and model number can be printed on the filter frame or label
Suitable for retail and e-commerce channels for furnace filters, AC filters, etc.
Multiple sizes can be mixed in one pallet or container. We will prepare a packing list before shipment to make unpacking and sorting easier in your warehouse.
Client Success Stories
Our partnerships speak for themselves:
Long-term Partners:
Several European HVAC suppliers have been sourcing from us for over 8 years-they keep coming back because we consistently deliver what they need, on time and as promised.
Custom Solutions: A client in the Middle East once approached us with humidity challenges. We developed a humidity-resistant variant for them, and it ended up cutting their maintenance costs by 30%-they were thrilled with the result.
Fast Turnaround: Even for small orders with custom branding, we can wrap up production in 15 days. It's all about keeping things efficient so clients don't have to wait around.
About Us
In recent years, we've been regulars at international purification exhibitions-from the 2009 Pakistan Exhibition and 2014 US Air Intelligence Exhibition, to the 2015 Vietnam and India shows, 2016 Thailand and Malaysia exhibitions, 2017 Turkey Expo, 2018 Australia Exhibition, 2023 Hong Kong Show, and 2024 Thailand Exhibition. Each time, we show up with genuine enthusiasm and top-tier product quality. Clients often take notice-they're impressed by the filters' performance, and our conversations flow easily. It's through these face-to-face interactions that many partnerships first take shape, with many clients turning into long-term collaborators after seeing our products up close. These shows haven't just helped us showcase what we do; they've let us understand global market needs better, making our products even more tailored to clients worldwide.
FAQ
Q:Are these disposable panel filters suitable as the only filter in a system?
A: In many comfort HVAC systems, yes-especially in simple commercial or residential units. In cleaner production or high-spec projects, they are usually used as the first stage, with higher-grade filters behind them.
Q: What information do you need to quote?
A: There are three main points: dimensions (width × height × thickness), media type (fiberglass or synthetic fiber), and expected efficiency range (e.g., G3–G4 / MERV 6–8). If you have a sample of the filter you're currently using, taking a few photos would be even more helpful.
Q: Can you supply different sizes in the same shipment?
A: Yes. We frequently ship 5–10 different specifications in one container to the same warehouse or multiple project sites. As long as you clearly list them in your order, we will palletize and label them according to the list.
