Configure to Order: Flexible Options for Custom Air Filters

Sometimes the filter you need already exists; it just doesn’t fit your dimensions or materials. Configure to Order lets you choose the dimensions, media, and performance levels that fit your application. We’ll build to those requirements so your custom air filters  work in your product where it counts.

Customize the air filter specs that matter most

From dimensions to efficiency ratings, Configure to Order puts the control in your hands. Here's what you can customize.

Dimensions & Filter Size

We cut to the filter size numbers you give us—length, width, depth—built with industry-standard tolerances so the filter installs without adjustment.

Media & Efficiency

From MERV to HEPA, ULPA, carbon, synthetics, or specialty blends, we match media to your performance targets and the environment your product runs in.

Frames & Housings

Metal or plastic, rolled, stamped, or welded, we build frames and housings in stainless, aluminum, galvanized, or composite to match strength, cost, and application needs.

Gas Phase & Odor Removal

Carbon media can be filled in bulk, bonded, or nonwoven formats to capture gases, VOCs, odors, and corrosives, keeping air quality safe and equipment protected.

Packaging & Labeling

Filters ship ready to use with options like barcoding, branded labels, kitting, shrink wrap, or dock-to-stock prep for faster handling.

Volume Flexibility

We run what you need, small pilot batches or large production runs, with just-in-time delivery to match your schedule.

Regulatory-Ready Options

Designs can be built to align with standards such as UL 900, ISO 16890, ASHRAE 52.2, FDA-grade, or flame-retardant requirements.

How Configure to Order Works

We keep things simple. Just send us the custom filter details and we’ll make sure the fit and performance are right, and production scales to match your build.

Why customize your filter specs?

Your customers expect performance, reliability, and trust. Configure to Order gives you the freedom to design filters that support your product vision while keeping costs and compliance in check.

Here’s what makes Rensa different

Details matter. We move fast without cutting corners, combining hands-on engineering with service that keeps projects on schedule.

Why partner with Rensa?

Because every filter solution we design is backed by collaboration, speed, and reliability—ensuring you get more than a product, you get a true partner.

Fast lead times

We know production moves fast. That’s why we deliver custom filters in as little as 7–10 days, keeping your build schedule on track.

Volume pricing

Annual buys shouldn’t break your budget. Lock in volume pricing that reduces cost per filter without sacrificing performance.

Reverse engineering

If a filter goes off the market, we’ll build one to match. Our team recreates discontinued parts so your equipment keeps working as intended.

Prototyping for validation

Before you scale, you need proof. We’ll send prototypes that match your design so you can test and tweak while there’s still time to adjust.

Proof in performance

We share the test data (efficiency, airflow, compliance) so you can see how the filter performs before you commit.
