PURE-D ensures flawless extraction of unpleasant odors so that you can leave the smallest room with your head held high.

Power outlet (110-240V)
Do you have a socket near the toilet? Then you can also opt for the version with power adapter. With this, the PURE-D is equipped with an USB cable (2m) at the back side of the toilet seat and a 5VDC USB adapter.
Automatic start-stop
A smart sensor knows when someone is sitting on the toilet and turns on the PURE-D automatically. When there’s no one sitting on the toilet, the PURE-D will continue ventilating for ashort period of time and will automatically turn off right after.
Odor detection
The PURE-D has a build-in smart odor sensor. If you ofter sit on the toilet for longer periods of time, the system saves energy by limiting the power of the fan. If necessary, the odor sensor reacts immediately and switches the fan back to standard power so that you can count on a flawless extraction and filtering of unpleasant odors.
No chemicals or other hazardous substances
Due to the optimal airflow combined with a carbon filter, the elimination of unpleasant odors can be done completely without chemicals or other harmful substances. This way it’s not only safe for yourself, but also for the environment.
Soft Close & Quick Release
The in-house developed Soft Close hinge system makes sure that the PURE-D always closes gently, silently and safely. With the Quick Release function you can remove the PURE-D from the toilet in 1 action easily to clean the toilet and the PURE-D.
Durable, antibacterial and scratch-free
The PURE-D is made from Duroplast, a practically unbreakable and light type of plastic. The PURE-D is also more hygienic, very user-friendly and scratch-free due to the extra smooth surface and the pore-free Duroplast material.
Replaceable filter
Thanks to the integrated filter, you can be sure of an optimally functioning system for at least 6 months(1). If your filter is saturated, you can order more filters from us. You can easily replace the filter and it’s also biodegradable.
