Koch SprayStop 3300 Series (Hi-Efficiency Expanded Paper) Paint Arrestor

Start with the booth manufacturer and model, then identify the filter slot location: intake (ceiling) filters sit upstream of the spray operation; exhaust (paint arrestor) filters sit downstream and capture overspray. Each stage uses different media designed for that purpose.

Then verify the slot dimensions on your booth — manufacturers occasionally revise filter slot specifications between model years and production runs. When in doubt, measure the existing filter or consult the booth manufacturer's documentation, or request a quote with your booth model and we'll confirm sizing.

Yes — custom paint booth filtration is made to specification for older booths, retrofits, and non-standard slot dimensions. Request a quote with the booth manufacturer, model, slot location (intake or exhaust), exact slot dimensions, and the media type or efficiency level required, and we'll confirm what's available and the production lead time.

You're covered by our Filter Fit Guarantee. If a stocked filter doesn't fit as expected, contact us within 30 days and we'll make it right — including a custom-sized replacement when slot dimensions don't match standard. Customers are responsible for verifying booth filter slot dimensions before ordering, but if you're close and the size is borderline, call us at 866-469-8556 before placing the order and we'll spec it correctly the first time.

Paint arrestor products in this catalog are commonly specified for auto body and miscellaneous surface coating operations regulated under 40 CFR Part 63 Subpart HHHHHH (6H). Specific product capture efficiency and ASHRAE 52.1 test data are listed in the product description.

The end user and facility operator are responsible for confirming that the selected filter meets the applicable rule for their specific coating operation and air permit. The product description contains the manufacturer-published performance data needed to make that determination.

Subpart 6H (40 CFR Part 63 Subpart HHHHHH) covers auto body refinishing, collision repair, and miscellaneous surface coating of motor vehicles and mobile equipment.

Subpart 6X (40 CFR Part 63 Subpart XXXXXX) covers area-source metal fabrication and finishing operations, including spray painting of fabricated metal parts.

Both rules require filter-based capture of paint overspray and particulate hazardous air pollutants, but capture-efficiency requirements, recordkeeping, and test methods differ. Operators are responsible for confirming which subpart applies to their facility.

No — we supply filtration products and general reference information. We do not provide regulatory determinations, permitting guidance, or legal advice. Determining which NESHAP subpart, state implementation plan, or local air district rule applies to a coating operation is the responsibility of the facility operator, in consultation with their environmental compliance officer or regulatory authority. We can confirm filter specifications and performance data once you know which rule and capture efficiency you need to meet.

Change cadence is driven by booth runtime, coating volume, paint type, and manometer reading — not by a calendar. Most operations replace exhaust paint arrestors when the booth's static pressure differential reaches the manufacturer's published change-out point (typically marked on the booth's manometer). Intake (ceiling) filters are usually changed on a longer cycle than exhaust arrestors.

Running filters past the change-out point reduces airflow, can compromise overspray capture, and risks pushing the booth out of compliance with its air permit. Booth manufacturer documentation is the authoritative source for change-out triggers on your specific equipment.

Intake (ceiling) filters sit upstream of the spray operation. Their job is to clean inbound air before it reaches the paint application zone — reducing dirt, lint, and airborne particles that would otherwise contaminate the finish. Common media: tackified polyester or fiberglass diffusion media.

Exhaust (paint arrestor) filters sit downstream of the spray operation. Their job is to capture overspray before exhaust air leaves the booth. Common construction: progressive-density paint arrestor pads, accordion-style fiberglass, or pleated panels engineered for high holding capacity.

Used paint arrestor filters loaded with paint overspray may be classified as hazardous waste depending on the coating chemistry, applicable state and federal rules, and how the facility manages waste streams. Disposal is the responsibility of the facility operator and should be handled in accordance with the facility's hazardous waste management program and applicable EPA, state, and local regulations. RememberTheFilter.com supplies replacement filtration; we do not provide waste disposal guidance.

Standard stocked paint booth filters ship within 1–2 business days from the warehouse nearest to your shipping address. Most orders arrive in 2–5 business days via UPS or FedEx for case quantities. Pallet quantities ship LTL freight with delivery typically within 5–10 business days depending on destination.

Custom-sized filters are made to order and have their own production lead time. Live timelines on our production schedule page.

Yes — pallet, partial-pallet, and full-truckload quantities are routine for collision shops, OEM finishing, and industrial coating operations. Pallet orders ship LTL freight to commercial addresses; residential delivery and lift-gate service are available at additional cost. Request a quote with your filter spec and quantity for pallet pricing and freight estimates.

Yes. Volume pricing, scheduled delivery, and standing rotation orders are available for collision centers, OEM finishing operations, government fleet maintenance, woodworking finishing, aerospace finishing, and industrial coating operations. Request a quote with your filter specs, booth manufacturer/model, and estimated annual volume, or visit Commercial Services for the full commercial lineup.

Yes to both. Purchase orders and net terms are available for established commercial accounts. RememberTheFilter.com is family-founded and supplies government and military buyers regularly — W-9, certificate of insurance (COI), NDAA Section 889 documentation, tax-exempt setup, and PO/net terms are all available on request.

For tax-exempt setup, submit your certificate through our tax-exempt purchases page and we'll configure your account so future orders ship tax-free with no repeated paperwork.

Yes — scheduled delivery on a cadence that matches your production rhythm is one of the most common arrangements for collision shops and OEM finishing accounts. Weekly, bi-weekly, monthly, or by-runtime triggers are all on the table for established accounts. Contact us at 866-469-8556 or request a quote with your facility's typical change-out cadence and we'll structure the standing order around it.
