We Solve More Than Just Size Problems

Standard catalog filters don't fit every system. Many buyers need non-standard dimensions, special frame materials, specific efficiency ratings, or unique sealing methods — and they simply can't find them off the shelf.

Clean-Link exists to build the filter your system was meant to have.

We don't start by asking for a full technical datasheet. Instead, we begin by understanding your real pain points:

• Is your current filter letting air bypass because it doesn't fit the rack properly?

• Is the standard filter depth too long for your confined installation space?

• Are you burning through filters too fast because the standard media can't handle your airflow or dust load?

Solve the problem first. Then talk about the product. That's our approach to every B2B partnership.

Standard vs. Custom: At a Glance

The real value of a custom air filter is this: it solves a real, application-specific problem that standard products can't address.

When Do You Need a Custom Air Filter?

If any of these five situations sound familiar, a standard product won't work — and you need Clean-Link.

1. Non-Standard Dimensions — It Doesn't Fit or Seal

Older equipment, imported systems, and retrofit projects often use filter sizes that aren't stocked anywhere. The wrong size means difficult installation, deformed filters, or air bypassing the filter entirely.
Our Solution: We manufacture to your exact length, width, and depth. The filter slides in perfectly. No gaps. No bypass.

2. Limited Installation Depth — Standard Is Too Long

Many AHUs and equipment have shallow filter housings. A standard-depth bag filter or compact filter simply won't go in.
Our Solution: We redesign the filter structure to maximize media area within your available depth — maintaining airflow while fitting your space constraints.

3. Airflow & Pressure Drop Mismatch — High Energy Bills

Two filters with the same dimensions can perform very differently under different airflow conditions. High airflow across an undersized filter causes pressure drop to spike, wasting energy and potentially triggering system alarms.
Our Solution: We select or engineer media with lower resistance, matched to your system's actual airflow. Less strain on your fan. Lower operating cost.

4. Harsh Conditions — Standard Media Won't Last

High humidity, corrosive gases, oil mist, or VOCs/odors? Standard synthetic or fiberglass media will fail prematurely.
Our Solution: We offer activated carbon, antimicrobial, oleophobic/hydrophobic, and high-temperature media, plus corrosion-resistant frames, to handle tough environments.

5. OEM & Private Label — You Need Consistency

As an equipment manufacturer or distributor, you need filters that are dimensionally identical every time, with your brand on the box and the product.
Our Solution: Full OEM & private-label support — custom dimensions, branded packaging, labels, and long-term supply agreements with price stability.

What Can Be Customized? Full Control Over Specifications

We don't just cut filters to a different length. We offer deep engineering customization to match your exact system requirements.

Our Custom Air Filter Workflow — Clear, Transparent, Predictable

We understand that B2B purchasing involves multiple stakeholders and careful planning. That's why our process is designed to be straightforward from start to finish.

Step 1: Requirement Gathering — As Easy as You Want It to Be

• Easy mode: Snap a photo of your old filter with a ruler next to it. Send it to us.

• Standard mode: Tell us your application, dimensions, and efficiency target.

• Expert mode: Share a drawing, CAD file, or physical sample.

• We never turn away an inquiry because you don't have complete data. We'll help you figure out what's needed.

Step 2: Engineering Review & Selection

Our team evaluates your application — airflow, pressure drop, operating conditions, and installation constraints — and recommends the optimal media, structure, and frame combination.

Step 3: Quotation & Sample Confirmation

You receive a detailed, line-item quote. For complex or high-volume projects, we can produce samples or send production drawings for your approval before moving forward.

Step 4: Manufacturing

Production begins based on confirmed specifications. Every batch is quality-checked at each stage to ensure consistency.

Step 5: Inspection & Packaging

Finished filters undergo final dimensional and visual inspection. They are then packed according to your requirements — bulk, individual cartons, or branded packaging.

Step 6: Repeat Supply Support

For OEM partners and maintenance programs, we offer long-term supply agreements, raw material price locking, and consistent batch-to-batch quality.

• Low-Friction Engagement: Whether you send us a complete CAD drawing or just a photo taken on your phone, we respond with clear next steps. We make it easy to get started.

• Application-First Support: Our team doesn't just sell filters. We help you select the right media, optimize pressure drop, plan replacement schedules, and troubleshoot installation issues.

Frequently Asked Questions

Q: What is a custom air filter?

A: A custom air filter is designed and manufactured to meet specific project requirements — non-standard size, special media, unique efficiency targets, custom frame or gasket, or OEM packaging.

Q: When do I need a custom air filter?

A: When standard sizes don't fit, your system has special airflow or pressure drop needs, the environment requires special media, or you need OEM/private-label supply support.

Q: I only know the length, width, and height of my old filter. Can I still request a quote?

A: Absolutely. This is the most common scenario. Just send us a photo of your old filter with a ruler or tape measure next to it. Or tell us your AHU model number — we can often cross-reference the OEM specifications.

Q: Does Clean-Link support OEM air filter manufacturing?

A: Yes. We provide full OEM services — custom dimensions, consistent repeat orders, private-label packaging, and long-term bulk supply for equipment manufacturers and distributors.

Q: What is the minimum order quantity (MOQ)?

A: MOQ varies by product type and complexity. We understand that projects start somewhere. Contact us with your requirements and we'll provide flexible options.

Q: Can you provide samples before bulk production?

A: Yes. For custom projects, we typically offer sample production or drawing confirmation before moving to full-scale manufacturing.
