Product details

Per the Koch OdorKleen ES product bulletin, the Koch OdorKleen ES is a MERV 8 extended-surface pleated panel filter that combines particulate filtration with carbon-impregnated odor and VOC removal in a totally disposable unit. Per Koch, OdorKleen ES uses a two-ply media element: a 100% mechanical upstream layer for particulate capture (rated 70% efficient for 3-10 micrometer particles), backed by a downstream layer impregnated with carbon media for absorption of volatile organic compounds (VOCs) and odors from the air stream. Per Koch, the carbon media carries a minimum activation of 60%, providing high odor absorption efficiency and extended lifecycle between filter changes.

4″ 500 FPM 0.29″ w.g. 1.0″ w.g. 9

Per Koch, the rated capacity (CFM) for each filter size at 300 FPM and 500 FPM face velocities is published in the OdorKleen ES bulletin. For the specific size you're ordering, refer to the Koch bulletin linked at the bottom of this page or contact RTF for assistance.

Applications (per Koch OdorKleen ES bulletin)

Per Koch, OdorKleen ES is specified for environments with light to moderate contaminant levels where both particulate filtration and odor/VOC control are required:

  • Commercial Office Buildings
  • Airports
  • Sports Arenas
  • Hospitals
  • Schools
  • Painting Facilities
  • Industrial Plants
  • Smoking Lounges

About carbon-impregnated odor and VOC filtration

Standard MERV 8 pleated filters capture particulate — dust, pollen, lint — but pass right through gaseous contaminants like cooking odors, paint fumes, off-gassing from new construction materials, and other VOCs that occupants describe as "smells" rather than "dust." Carbon-impregnated filters add a downstream layer of activated carbon media that adsorbs (traps onto the surface of) gas-phase molecules as the air stream passes through. Per Koch, OdorKleen ES carries a minimum 60% carbon activation, which is the measure of how much VOC adsorption capacity the carbon layer can deliver before saturation. Higher activation = longer service life before odor breakthrough.

Where OdorKleen ES fits: Office buildings dealing with cleaning chemical complaints, schools with art-room or science-lab odor transfer, hospitals managing waiting-room and visitor-area smells, painting facilities controlling solvent overspray drift to office areas, and historically smoking lounges (a classic OdorKleen application). For higher contaminant loads or specific gas removal (e.g., formaldehyde, hydrogen sulfide), Koch offers higher-grade gas-phase filters — contact RTF support if your application needs more capacity than OdorKleen ES.

Sizing and ordering notes

  • Sizes are nominal. Per Koch K-100B (Multi-Pleat XL8 frame family), actual dimensions are typically 1/2″ less than nominal in width and height, and 1/4″ less in depth. Example: 20x25x1 nominal = 19-1/2″ x 24-1/2″ x 3/4″ actual.
  • Match your filter slot to the nominal size shown. Standard HVAC filter racks are sized to nominal dimensions; the actual filter slips into the rack with appropriate clearance.
  • Each variant ships in the case quantity shown. Per Koch sheet notes: "These products shipped in full cartons only."
  • "Call for Quote" sizes: Some sizes are available by special order only. Request a quote for these or for facility-scale orders.
  • Replacement schedule: Standard MERV 8 maintenance interval (typically 90 days for office HVAC), but odor breakthrough is the practical end-of-life signal — if you start smelling what the filter is supposed to be capturing, the carbon layer has saturated and it's time to replace, regardless of pressure drop.
  • Operating temperature limit: Per Koch, continuous operation up to 120°F (49°C). Not suitable for high-temperature exhaust applications.
  • Disposal: Filters loaded with VOCs may have specific disposal requirements depending on your jurisdiction and the contaminants captured. For painting facility or industrial applications, follow your local hazardous waste regulations.

Koch product literature

Detailed product specifications, capacity tables, and complete performance data for Koch OdorKleen ES are published in the Koch OdorKleen ES product bulletin: OdorKleen ES Product Specification PDF (Koch Filter Corporation). Per Koch, actual filter dimensions reference Bulletin K-100B (Multi-Pleat XL8 frame family). Both bulletins are available through Koch Filter Corporation (kochfilter.com) or by request through RTF.

Customer Reviews

What customers say about Koch OdorKleen ES (MERV 8 Carbon Particulate Filter for VOC and Odor Control)

Frequently Asked Questions

Answers to the questions we get every day

From sizing and MERV ratings to bulk orders and subscriptions — here's what customers ask before they buy. For product-specific specs, check the description above.

Sizing & fit
How do I know what size filter I need?

The size is printed on the edge of your current filter. Read the nominal size — for example, 16x25x1 — and order that size. The actual filter will measure about 1/2″ less than the nominal size on each dimension. That's industry standard and is how the filter slides into the slot without binding.

If the printed size is worn off, measure the filter slot itself — not the old filter — and round up to the nearest standard size. Our How to Measure guide walks through it step by step.

What if the filter doesn't fit my system?

You're covered by our Filter Fit Guarantee. If the filter doesn't fit your system as expected, contact us within 30 days and we'll make it right — including custom-sized replacements for non-standard slots. One flat $30 fee covers exchanges under the guarantee, and we'll walk through sizing with you so the replacement fits the first time.

Do you offer custom filter sizes?

Custom filters are made to specification down to 1/8″ precision — useful for older homes, clinical spaces, schools, and commercial AHUs with non-standard slot dimensions. Available in every MERV rating from 1–4 through 13, plus washable and extended-surface options.

If you don't see your size listed in our standard lineup, contact us or request a quote and we'll confirm what's available in the media and efficiency you need.

MERV & performance
What is a MERV rating and which one do I need?

MERV (Minimum Efficiency Reporting Value) is the industry-standard scale for how effectively a filter captures airborne particles. Higher numbers capture smaller particles. Most homes do well on MERV 8 to MERV 11. MERV 13 is the step up for pets, allergies, or wildfire smoke exposure — if your HVAC system supports it.

The MERV Rating Explained guide has the full breakdown, or take the 60-second MERV quiz for a personalized recommendation.

Will a higher MERV filter hurt my HVAC system?

Not when it's matched properly. Higher MERV filters do add airflow resistance, but most modern furnaces and air handlers handle MERV 11 comfortably, and many support MERV 13 — especially systems with 4″ or deeper media cabinets. The filter slot depth matters as much as the MERV rating.

Older systems (pre-2000) or tight 1″ slots may struggle with MERV 13. If airflow feels weak from vents, the blower sounds strained, or the coil ices up, step back down to MERV 10 or MERV 11. When in doubt, upgrade in steps — MERV 8 → 11 → 13 — and monitor for a cycle before moving up again.

What's the difference between MERV, MPR, and FPR ratings?

MERV is the universal industry standard, published through ASHRAE 52.2 testing and used by HVAC professionals worldwide. MPR (Micro-Particle Rating) is 3M's internal scale for their Filtrete line. FPR (Filter Performance Rating) is Home Depot's proprietary rating for filters sold in their stores.

MPR and FPR roughly correlate to MERV within their own brand lineups, but they aren't directly comparable across retailers. A Filtrete MPR 1900 is roughly MERV 13; an FPR 10 is also roughly MERV 13. Always check the MERV rating for an apples-to-apples comparison.

What is pleated filter media made out of?

Pleated filter media is a synthetic nonwoven fabric — most often polyester, sometimes a cotton-polyester blend — pleated over a supporting frame of galvanized wire or paperboard. The pleats add surface area, and the frame holds them open so the media keeps its shape under airflow.

Shipping & delivery
How fast will my filter ship?

Standard stocked 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. Custom-sized filters are made to order and have their own production lead time listed in the product description.

Current production and shipping timelines are always live on our production schedule page.

Do you ship to Alaska, Hawaii, or PO boxes?

We ship to Alaska and Hawaii — shipping is calculated at checkout based on the address. Free shipping on orders $50+ applies to the lower 48 contiguous states only; AK and HI orders ship at carrier rates.

PO boxes cannot be accepted. Filter boxes are physically oversized and our carriers (UPS and FedEx) won't deliver to PO boxes at this size. You'll need a street address, business address, or pickup location for delivery.

Orders, returns & subscriptions
Can I return or exchange a filter I don't need?

Unopened stocked filters can be returned within 30 days under our refund policy. Custom-sized filters are made to your specification and aren't returnable unless they arrived damaged or incorrectly sized from us.

If a filter arrives damaged or doesn't match what was ordered, submit a claim and we'll replace it — no back-and-forth.

How does the subscribe & save option work?

Most filters ship on recurring delivery at a 10% discount — cadences from every month through every 6 months, plus an annual option at 5% off. Pick the interval that matches your change-out schedule on the product page, and we'll auto-ship on time with no reordering required.

You're only charged when an order ships, and the discount applies to every delivery — not just the first one.

Can I pause, skip, or change my subscription?

Yes, any time. Pause, skip a delivery, change the cadence, swap the filter, update the shipping address, or cancel entirely — all from your account dashboard. No emails required, no hold times, no cancellation fees. See our subscription policy for the full details.

Bulk, commercial & tax-exempt
Do you offer bulk pricing for schools, clinics, or property managers?

Yes — bulk and volume pricing is available for facilities, multifamily properties, fleets, and any organization ordering in standing rotation. We work with schools, clinics, property management companies, government agencies, and industrial facilities on recurring orders with negotiated pricing.

Request a quote with your filter specs and estimated annual volume, or visit our Commercial Services page to see the full commercial lineup.

Are you set up for tax-exempt and government purchases?

Yes. We work with schools, government agencies, non-profits, and resale-exempt buyers regularly. Submit your certificate through our tax-exempt purchases page and we'll set up your account so future orders ship tax-free with no repeated paperwork. Purchase orders and government procurement are supported for established accounts.
