Give your equipment the protection it deserves with a custom-fit filter solution from Universal Air Filter (UAF). Fit it to your board, your rack, your cabinet—especially if it wasn’t designed with one.

As an engineer or equipment manufacturer, you know all too well: air, dust and debris don’t wait for “perfect conditions.” Whether you’re building a high-performance computing system, a telecom rack, a compact OEM appliance or gear destined for a dusty or salty environment, extending system life and reducing maintenance starts with the right air filtration. But what if your enclosure has no filter slot, only a tiny vent, or just wasn’t built for the environment you’re deploying it in?

That’s where UAF’s DIY Filter Kits comes in: we walk you through how to add a custom filter (or retrofit one) that fits your exact shape, size, and spec—so you can stop adapting your system to a generic filter, and instead let the filter adapt to your system!

DIY Filter-Build Steps (for *Engineers & OEMs)

Here’s how to approach adding/creating a filter for an enclosure that didn’t come with one (or needs an upgrade).

1. Audit the application environment

• What contaminants are present (dust, salt, moisture, water ingress, EMI, etc.)?
• What airflow/cooling path does your system require?
• What space constraints exist (thin profile, rack depth, curved surfaces, irregular frame)?
• What industry/standards must you meet (UL 94 HF-1, UL 60950, NEBS, IP/NEMA rating, etc.)?

2. Determine filter requirements

• Decide on frame layout: will it be a retrofit panel, a slot filter, a wrap-around basket, or cable/vent pass-through?
• Choose media: e.g., open-cell foam for airflow, closed-cell for tight seal, hydrophobic mesh for water protection.
• Define form-factor: thickness, mounting method, gasket, sealing surface, cut-out. UAF’s online CAD tool can help.
• Specify performance: target MERV rating or equivalent, dust holding capacity, cleanability, fire safety, reuse/maintenance cycle.

*_{Note: Installing a custom filter into an existing design may affect airflow, thermal performance and service interval. Always validate with your system and environment. UAF recommends integration by qualified engineers or OEM teams.}
