An un-smelly toilet without chemicals

We’ve never liked adding chemical to our toilet cassette, and so we’ve tried a few different things. But finally, we have a system that we think is great.

Last year we installed a toilet ventilation system onto our toilet cassette. It extracts smells from the toilet cassette and pulls them through a filter before releasing the air to the outside world. The system is great, apart from one thing: the filters. We found they were hard to get where we were travelling, expensive, and were synthetic: so, ‘bad’ waste for the environment. Then, we came up with a new filter system. 

First we made a filter container by stapling wire fly-screen, to make a container that fit where the original filter would have been housed. 

 Then we filled it with carbon pellets like used in aquariums. We bought our pellets in a small town pet shop without a lot of choice, there are probably many other carbon pellet options.

Then installed it. 


We’ve been using this system for just over 2 months now and it’s still working fine. When the time comes we will easily dispose of the charcoal pellets and add fresh ones to our basket.  

We don’t expect this method to damage our system in any way, but if you choose to do this please note that you may be voiding any warranty with the product manufacturer and you should make your own assessment as to whether this system might help you.
