Why MERV 13 plus carbon

Standard MERV 13 pleated filters capture fine particulate (smoke, fine dust, virus-sized particles) but do nothing for gas-phase contaminants — odors, VOCs, and the specific gases that activated carbon is designed to adsorb. Standard carbon-impregnated filters target gases but typically deliver only MERV 8 particulate efficiency, missing finer particles.

The OdorKleen 200/M13 is engineered for applications that need both:

  • MERV 13 particulate efficiency — captures fine particles down to sub-micron sizes including wildfire smoke, virus-laden aerosols, and fine industrial particulate
  • 200 gsm carbon load — provides gas-phase adsorption capacity for odors, VOCs, and the specific gases listed in Koch's features (ammonia, formaldehyde, sulfur dioxide, hydrogen sulfide)
  • Tradeoff: The MERV 13 layer is denser than the MERV 10 layer in OdorKleen 600, which costs airflow. The 200/M13's 2″ depth has higher initial resistance (0.53″ w.g. at 500 FPM) than the 600's 2″ depth (0.45″ w.g.). Verify your HVAC system can handle the higher pressure drop before specifying.

OdorKleen 200/M13 construction and specifications

  • Form factor: Extended-surface pleated panel with two-stage media (gas-phase carbon + MERV 13 particulate layer)
  • Carbon load: 200 gsm of granular activated carbon (per Koch). Koch describes the carbon as having "nearly five million square feet of surface area per pound."
  • Particulate layer: Polyester blend MERV 13 efficiency layer
  • Media: 100% synthetic carbon-impregnated mechanical media
  • Media support: Self-supporting
  • Frame: High wet-strength beverage board with cross-member designed to increase filter strength and rigidity. Frame is recyclable.
  • MERV rating: MERV 13 per ASHRAE Test Standard 52.2
  • UL certification: Underwriters Laboratories classified to UL 900
  • Maximum continuous operating temperature: 180°F (93°C)
  • Recommended Final Resistance: 1.2″ w.g.
  • Available depths: 1″, 2″, and 4″
  • Disposability: Single-use disposable; not washable

Performance data by depth

Filter Depth Test Air Velocity Initial Resistance Recommended Final Resistance Pleats / Linear Foot
1″ 300 FPM 0.34″ w.g. 1.2″ w.g. 15
2″ 500 FPM 0.53″ w.g. 1.2″ w.g. 14
4″ 500 FPM 0.48″ w.g. 1.2″ w.g. 9

The MERV 13 particulate layer delivers finer filtration than the MERV 8 or MERV 10 layers in other OdorKleen products, with corresponding higher pressure drop. Pleat density at 1″ (15 pleats per linear foot) and 2″ (14 pleats per linear foot) provides the media area needed for both fine particulate capture and gas adsorption.

Targeted gaseous contaminants

Per Koch's product features, OdorKleen 200/M13 is designed to remove:

  • Ammonia (NH3) — alkaline gas common in pharmaceutical, agricultural, and laboratory environments
  • Formaldehyde (HCHO) — off-gas from new construction materials, laminate adhesives, embalming, and some manufacturing processes
  • Sulfur dioxide (SO2) — combustion byproduct and industrial process contaminant
  • Hydrogen sulfide (H2S) — rotten-egg odor at low concentrations, toxic at higher levels; common in wastewater treatment, oil & gas, and certain industrial processes

Applications

OdorKleen 200/M13 is specified for environments needing both fine particulate filtration and gaseous contaminant control:

  • Chemical Storage
  • Laboratories
  • Museums and Archives
  • Pharmaceutical
  • Hospitals
  • Airports
  • Industrial Facilities
  • Commercial Office Buildings
  • Sports Arenas
  • Smoking Lounges
  • Casinos
  • Laminate Adhesives (manufacturing)
  • IAQ Emergency response

Choosing the right OdorKleen tier

Koch produces four carbon-impregnated pleated filters in the OdorKleen product family. Choosing between them depends on whether you need higher particulate efficiency or higher carbon capacity:

  • OdorKleen 200/M13 (this product): MERV 13, 200 gsm carbon. Highest particulate efficiency in the family. Use when fine particulate (wildfire smoke, virus aerosols, fine industrial dust) is the primary concern AND gas-phase capacity is needed.
  • OdorKleen 600: MERV 10, 592 gsm carbon/alumina blend with 5% KMnO4. Highest carbon capacity in the family. Use when gas/odor removal is the primary concern, especially for ammonia, formaldehyde, SO2, H2S in heavy industrial settings.
  • OdorKleen 250: MERV 8, 250 gsm CarbonWeb® carbon with potassium permanganate alumina. Mid-tier general carbon filter for heavy VOC loads. Use for pharmaceutical, lab, museum applications without the MERV 13 requirement.
  • OdorKleen ES: MERV 8, basic carbon impregnation. Standard carbon-impregnation pleated filter for lighter contaminant loads. Use for office buildings, schools, and standard HVAC environments with light to moderate odor and VOC loads.

If you're unsure which tier fits your application, contact RTF support with your contaminant profile, target gases, particulate concerns, and operating conditions, and we'll help match the right filter.

Sizing and ordering notes

  • Sizes are nominal. Match nominal dimensions to your filter slot. Actual filter dimensions are typically 1/2″ less than nominal in width and height per the Multi-Pleat XL8 frame family standard.
  • Carton qty varies by depth: 1″ ships 12 per case, 2″ ships 6 per case, 4″ ships 3 per case — reflecting filter weight and shipping density.
  • Additional small sizes available: Per Koch, the OdorKleen 200/M13 product line includes 12″x12″x1″ and 12″x12″x2″ sizes not stocked in this RTF lineup. Request a quote for these or for custom sizes.
  • Pressure drop consideration: The MERV 13 layer means higher initial resistance than other OdorKleen products. Verify your HVAC system fan capacity can handle the airflow demand before specifying, especially for retrofit applications.
  • Replacement schedule: Standard MERV 13 maintenance interval applies, but odor breakthrough or gas-specific breakthrough is the practical end-of-life signal — if ammonia, formaldehyde, sulfur, or hydrogen sulfide odors return, the carbon has saturated regardless of pressure drop.
  • Operating temperature: Continuous operation up to 180°F (93°C). Suitable for elevated-temperature HVAC applications.
  • Disposal: Filters loaded with target gases (ammonia, formaldehyde, SO2, H2S) or other industrial contaminants may have specific disposal requirements depending on captured contaminants and quantities. Follow your local hazardous waste regulations.
  • Frame is recyclable once stripped of the spent media.
  • UL 900 classified — meets standard UL fire and flammability classification for HVAC air filters.

Customer Reviews

What customers say about Koch OdorKleen 200/M13 (MERV 13 High-Capacity Carbon Particulate Filter)

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.
