Frequently
Asked Questions
Q. Does the Maxi-Filtra really work?
A. Yes, provided that the odours
you are suffering from are eminating from the ventilation pipe the Maxi-Filtra definitely solves the problem. We have now sold many hundreds of Maxi-Filtras and we receive only positive feedback.
Q. What can't the Maxi-Filtra do?
A. The Maxi-Filtra prevents unwanted odours from escaping via the ventilation pipe. It can't do anything about
odours eminating from other parts of the sewage system such as a broken
covers or leaking pipes.
Q. How does the Maxi-Filtra work?
A. The Maxi-Filtra contains
a cartridge of Activated Carbon that prevents the Sulphides, which cause the smell, from reaching the atmosphere. Air can pass through the filter in either direction, allowing the system to "breathe", but the bad smells can't escape. more info
