Innovative resin in service of cleaner spaces
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.
Make filtration invisible.
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.

A short version of the journey from a single polymer formulation to a finished consumer brand.
CRP-int bv is founded in Arendonk
The company starts with a single mission: develop polymer filter resin that captures unwanted gases naturally — without combustion, fragrance or external power source.
From resin to filtration partner
Filter media are integrated into industrial OEM products and water-treatment cartridges across Europe.
Hospitality enters the roadmap
Listening to hotel and resort operators, we begin work on a finished consumer cartridge for guest rooms.
Sentipure Pro launches
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.
Sustainable, European, hands-on
Production stays in Arendonk to keep CO₂ low and quality close. We work directly with operators, OEMs and distributors to fit each environment.
Three values, kept simple
Capture, don't mask
If the molecule is gone, the smell is gone. Fragrance is camouflage; absorption is the solution.
European by design
Production lives next door to R&D. Shorter shipping, tighter quality, smaller carbon footprint.
Service over sales
Our best customers are the ones who keep buying. We design products that last and people who answer the phone.
