CRP-int bv develops polymer filter resin that captures unwanted gases and odors at the molecular level — without fragrances, without external power source, without compromise. From hotel rooms to nursing homes, our media keeps indoor environments fresh and healthy.
For three decades we've been refining the absorption of odour molecules. Today our filter media is inside 50+ brands, distributed across 31 countries and over 12,000 stores — from hotel rooms and nursing homes to cat litter boxes, aquariums and car cabins.
Custom-tuned resins that adsorb ammonia, formaldehyde and volatile organic compounds — engineered for industrial and consumer applications.
A finished consumer cartridge for hotels, B&Bs, lodges and care facilities. Easy to install, easy to refill, works for up to 30 days per sachet.
Manufactured in Arendonk, Belgium with a focus on low CO₂ logistics and recyclable packaging — sustainability is part of the spec sheet.
CR Resin is a polymer filter resin developed and continuously refined since 1993. Its molecular structure presents maximum surface area to gas — and molecularly binds ammonia, formaldehyde and VOC molecules rather than physically trapping them.
The principle: If the molecule is gone, the smell is gone. Fragrance is camouflage; absorption is the solution.
80% of travelers report odor discomfort in hotel rooms. Spraying scent over the problem can backfire — once the fragrance fades, the underlying odor often returns stronger than before. Our resin captures the molecules instead of masking them.
Tell us about your rooms, your guest profile, your odor challenges. We'll recommend the right pack and quantity.
Founded in 1993 in Arendonk, Belgium, CRP-int bv has spent three decades developing polymer filter media that capture unwanted gases and odors at the source — quietly, naturally, and without an external power source.
The best filter is one you never notice. No buzzing motor. No artificial fragrance. No replacement schedule that disrupts the room. Our resin works in the background, neutralising ammonia, formaldehyde and a range of volatile organic compounds before they reach the people you serve.
Whether the application is a hotel suite, a nursing home corridor or an OEM water-treatment cartridge, the principle is the same: capture, don't mask.
See what we make →A short version of the journey from a single polymer formulation to a finished consumer brand.
The company starts with a single mission: develop polymer filter resin that captures unwanted gases naturally — without combustion, fragrance or external power source.
Filter media are integrated into industrial OEM products and water-treatment cartridges across Europe.
Listening to hotel and resort operators, we begin work on a finished consumer cartridge for guest rooms.
A premium peel-and-stick air filter for hotels, B&Bs, lodges and care homes. Up to 30 days of fresh air per sachet, no external power source required.
Production stays in Arendonk to keep CO₂ low and quality close. We work directly with operators, OEMs and distributors to fit each environment.
If the molecule is gone, the smell is gone. Fragrance is camouflage; absorption is the solution.
Production lives next door to R&D. Shorter shipping, tighter quality, smaller carbon footprint.
Our best customers are the ones who keep buying. We design products that last and people who answer the phone.

The polymer science behind every CRP-Int product — how the resin is made, what it absorbs, and why it works without electricity, fragrance or filters that need replacing every week.
A unique polymer formulation developed and continuously refined since 1993. The resin works on the principle of absorption — molecularly binding unwanted gas molecules rather than merely trapping them physically.
The unique formula — manufactured and processed since 1993 — begins as raw polymer precursors. The molecular structure is engineered to present maximum surface area for gas capture.
In the second production phase the resin is built up and polymerisation begins. Granules charge up, developing absorbent binding sites for ammonia, formaldehyde and VOCs.
The resin cools to room temperature. The finished granules are highly porous, strongly adsorbent for polar gases, and work excellently even in humid environments.

Zolux's aquarium line. Resifilt cartridges combine CR Resin with mechanical media for nitrate / nitrite removal in both aquariums and small ornamental ponds.
One of France's leading aquarium and pond brands.
Reptile keepers face two distinct challenges. Dry terrariums for snakes, lizards and geckos generate ammonia and organic odours from waste and shed skin — the gas-phase CR Resin handles those. Turtle tanks and aquatic-reptile setups are wetter and more nutrient-rich than typical aquariums — the aqueous-phase resin tackles dissolved nitrates, nitrites and phosphates that drive cloudy water and algae. Same filter resin family, different grain size and format.
Two grain sizes available — fine 2–4 mm for compact under-tank cartridges, coarse 4–10 mm for canister and corner filters in turtle tanks.
The fastest-growing segment for Sentipure Pro. Hotel rooms, B&Bs, lakeside cabins, Airbnb properties, holiday rentals — guests don't remember the room that smelled fine, but they always remember the one that didn't. Click a property type below for the full deployment story.
Hotels live and die on the first 30 seconds in the room. Stale tobacco, last-night's dinner, ammonia from the en-suite, the lingering perfume of the previous guest — once a review mentions a smell, the booking score drops for months. Sentipure Pro mounts behind the bed or in the bathroom and silently absorbs odour molecules at the source for 30 days, before housekeeping has to react to a complaint.
Designed to disappear into the wall. Guests notice the room smells fresh; they don't notice why.
Sentipure Pro is CRP-Int's flagship hospitality brand: a discreet, fragrance-free CR Resin cartridge that captures ammonia, organic odours and VOCs in hotel rooms, B&Bs, lakeside cabins, Airbnb properties and holiday rentals. One brand, five industry tiers.
Built for hotel rooms, B&B suites, holiday cabins, hunting lodges and Airbnb properties. Peel-and-stick installation — no wiring, no batteries, no fragrance. The CR Resin sachet absorbs odours passively while you sleep, cook or work.
Discreet, brand-appropriate, fragrance-free. Operators love it because it doesn't compete with the room scent — it just makes the air read clean.
For hotel chains and large operator groups: Sentipure Pro is available as a fully custom-branded cartridge. Your colours, your logo, your packaging — CRP-Int's CR Resin sachet inside. Minimum order quantity from 6 display units.
Whether you operate 6 boutique hotels or 600 — we co-design a cartridge that fits your brand and ships at the volumes you need.
Bed-and-breakfast properties have a distinct challenge: the breakfast smell is part of the brand, but only at breakfast. Once a guest is back in their room, the lingering aroma of bacon, coffee or kippers transferring from the dining room to the upstairs guest rooms becomes the wrong kind of memorable. Sentipure Pro absorbs cooking-derived VOCs and the usual ammonia / sweat compounds without a competing fragrance — keeping rooms neutral, the breakfast service smelling great, and the two clearly separate.
Designed for small properties where the dining room and the guest rooms share the same airflow. Captures cooking-transfer VOCs without scrubbing the breakfast experience.

Lakeside lodges, ski cabins, hunting lodges and wilderness retreats face a different odour profile than urban hotels. Wood-burning stoves leave a lingering smoke residue, damp clothing dries indoors, wood-clad walls trap odours over decades. The CR Resin captures both the polar VOCs from woodsmoke and the ammonia / mildew compounds from damp gear — without competing with the natural cedar or pine aroma that's part of the property's character.
Designed for properties where wood, woodsmoke and seasonal damp build up faster than in urban hotels. Tested for stable performance in cold, humid conditions.

Airbnb hosts know the truth: a single guest review mentioning a smell can drop a property's nightly rate for months. The space is too lived-in for industrial cleaning to work between guests, the host isn't there full-time, and air fresheners are the most common complaint after the smell itself. Sentipure Pro is the host's silent partner — peel-and-stick, fragrance-free, lasts 30 days, and quietly absorbs the residue every previous guest leaves behind.
Designed for short-let properties — quick to install, invisible to guests, and won't show up in a "smells artificial" review.

Holiday-park cabins, beach huts, vineyard guest cottages and seasonal rental properties have a problem most year-round properties don't: they're closed for weeks or months at a time. Whatever odour was there at the end of October is still there in April, often amplified by trapped damp. Sentipure Pro deployed at season's end works through the closure period, capturing ammonia and VOC residue while the property is empty — so the first guests of the new season walk into a fresh space, not a stale one.
Engineered to keep working between guest stays — even when "between" means a four-month winter closure.

The Sentipure family for newborns: a home-grade Diaper Pail Odor Filter for the family nursery, and the professional Sentipure Pro for multi-room day-care, crèche and nursery facilities. Both 100% fragrance-free, both NedLab-certified.
The Sentipure cartridge absorbs ammonia and organic odours from soiled diapers. It fits most standard diaper pails and nappy bins, keeping the nursery clean without masking agents, fragrance or electricity — the safest possible environment for a newborn's developing respiratory system.
Hundreds of micro-pores on each granule absorb odours like a sponge, locking them away at the molecular level — keeping the nursery fresh for up to 30 days, with zero need for external power source and zero fragrance.
A baby day-care or crèche handles dozens of nappy changes per day across a small footprint. The Sentipure Pro cartridge is wall-mounted at the nappy-change station and inside disposal pails — capturing ammonia at the source for infants whose respiratory systems are still developing. No fragrance to mask, no chemicals to inhale, nothing for parents or regulators to second-guess.
One Sentipure Pro per nappy-change station, plus one inside each disposal pail. A typical day-nursery room is fully covered with two to three units.
Footwear, locker rooms, gym floors — the same complex mix of ammonia, fatty acids and short-chain VOCs that creates "sports smell." CR Resin captures it at the molecular level, in three different formats sized to the space. Click an application below.
Sweat and bacterial activity inside sports shoes produce persistent organic odours — a complex mix of ammonia, fatty acids and short-chain VOCs. The CR Resin sachet slips inside the shoe and absorbs these gases at the molecular level. No spray, no powder, no fragrance — and no residue when you put the shoe back on.
Compact, dry resin sachet designed for the inside of sports shoes, lockers and gym bags. Starts working the moment it leaves the wrapper.
Sports clubs, schools and gyms all share the same problem: hundreds of items of damp kit, hundreds of pairs of post-workout trainers, all sealed inside metal lockers between sessions. The CR Resin Locker Pack is sized for the inside of a single locker — captures sweat-derived ammonia, fatty acids and the persistent VOCs that build up in enclosed kit storage, without resorting to overpowering deodoriser sprays that linger on the kit itself.
Compact dry sachet designed to slot inside individual locker units — installs in under five seconds, replaces in less.
Commercial gyms, boutique studios and CrossFit boxes all run into the same wall: HVAC dilutes odour but doesn't capture it, scented cleaners just shift the problem, and member surveys consistently flag "smell" as a top three reason for cancellation. Sentipure Pro mounts behind cardio equipment, in changing-room corridors and around mat-floor zones — passively absorbing ammonia, sweat-VOCs and the residual odour of yesterday's class for the full 30 days between cartridge changes.
Designed for the high member-density, high-airflow environments where standard HVAC dilutes but doesn't capture. Mounts behind equipment.
Healthcare environments need odour control — but the patients in them often can't tolerate fragrance. CR Resin captures ammonia, formaldehyde and biological VOCs without releasing anything in return. Click an application below for the full spec.
Adult day-care facilities serve seniors and adults with mobility or memory needs for 6–10 hours at a stretch. The spaces handle continence-care needs throughout the day, in a setting that's part-clinical, part-living-room. Sentipure cartridges absorb ammonia silently, without fragrance, so the room stays welcoming for everyone — guests, staff and family members visiting at pickup time.
The Sentipure cartridge fits the same wall-mount used in nursing-home rooms, scaled for the larger floor-plate of a day-centre common area. Bulk multi-room packs available for facilities with multiple wings.

For hotel chains and large operator groups: Sentipure Pro is available as a fully custom-branded cartridge. Your colours, your logo, your packaging — CRP-Int's CR Resin sachet inside. Minimum order quantity from 6 display units.
Whether you operate 6 boutique hotels or 600 — we co-design a cartridge that fits your brand and ships at the volumes you need.
Truck drivers spend 9–12 hours a day inside the cabin. The combination of diesel-traffic ammonia, off-gassing from upholstery, and air drawn from busy industrial zones builds up faster than any standard pollen filter can handle. CR Resin sits in the cabin air-filter housing and captures the gas-phase contaminants the standard filter lets through.
Custom-spec cartridges for European HGV and LCV manufacturers, plus aftermarket retrofit cartridges for fleet operators concerned about driver air-quality exposure.
Sentipure Pro is CRP-Int's flagship Transport & Logistics brand: a discreet, fragrance-free CR Resin cartridge that captures ammonia, organic odours and VOCs in cars, truck cabins, taxis, RVs & motor homes and caravans. One brand, five industry tiers.

Taxi and ride-share cabins handle 20–40 different passengers a day, each bringing their own scent profile — perfume, food, smoke, sweat. CR Resin sits in the cabin air filter and captures these organic odours as they cycle through the recirculation system. The driver gets a cleaner work environment, and every new passenger steps into a neutral cabin — not one that smells of the last fare.
The same cabin filter format used in private cars — fitted with the high-performance CR Resin layer that handles passenger-turnover odours rather than just road-pollen.

An RV or motor home is part vehicle, part living room, part bedroom — and all of it is enclosed. Cooking, sleeping and pets all happen in the same space, often with the windows closed at night or in bad weather. CR Resin captures ammonia, cooking-VOCs and pet-odours from the cabin air, so a 10-day road trip ends as fresh as it started.
Two formats for the recreational-vehicle market: cabin-filter cartridge for the HVAC system, and a wall-mounted Sentipure unit for the living-space air.

Caravans and trailers spend most of the year in storage — and a closed caravan with no airflow is a perfect environment for stale-air build-up, damp odours and lingering ammonia from the previous trip's chemical toilet. CR Resin works passively while in storage, capturing the odours that would otherwise greet the family the next time they unzip the awning.
The same Sentipure technology, with extended-life packaging for the long storage periods caravans typically face. Wall-mountable inside the caravan to work through the off-season.

Wherever there's a toilet, there's an ammonia-rich environment that needs to be managed without drainage, electricity or service-crew interruption. CR Resin captures ammonia and organic odours passively, on a 30-day rotation. Click an application below.
Home bathrooms are typically small, often windowless, and accumulate ammonia from regular use. Most households default to scented sprays or plug-ins, which mask the problem briefly and add chemicals to a small space. The Sentipure cartridge mounts on the wall, captures the molecules at source, and lasts a month — quietly, with zero fragrance.
Peel-and-stick, fragrance-free, 30-day cartridge. Designed for the small enclosed footprint of a typical home bathroom.

Public restrooms in offices, retail spaces, transport hubs and entertainment venues see hundreds of users per day. The cleaning team can keep surfaces spotless, but ammonia builds up in the air faster than scheduled cleans can address it. CR Resin captures it continuously between cleaning rotations — so the experience for the next user is consistent, regardless of who came before.
Higher-capacity cartridge format for high-traffic public facilities. Wall-mountable in stall and lobby areas, with bulk-supply options for facility-management operators.

Mobile toilets, festival cabins, construction-site units and marina facilities all share the same problem: high ammonia load, no electricity, no plumbing for active ventilation, and a service crew that visits once a week. CR Resin works passively — no fan, no external power source, no liquids — and is rugged enough for outdoor cabins exposed to heat, cold and humidity.
Designed for mobile-toilet operators, event-sanitation companies and construction-site managers. The cartridge fits inside the cabin's existing odour-control housing and is replaced as part of the standard servicing rotation.

Feminine-hygiene disposal units are a routine fixture in office, retail and hospitality washrooms — but the difference between a serviced unit and a neglected one is immediate to every user. Our resin cartridge sits inside the disposal box and absorbs ammonia and organic odours continuously between service visits, so the unit stays presentable for the full 30-day rotation. Supplied as OEM cartridges to commercial hygiene-service providers across Europe.
Custom cartridge formats for the leading hygiene-service brands. Slot directly into the lid or back wall of the unit, and last the full service rotation.
