Before embarking on our pursuit, we first analysed the current solutions
that are available for deodorization of toilets and their short-comings. A
summary of our findings can be obtained here.
1) Perfume or Naptha balls: This is the most commonly used method for tackling
toilet odour. Perfumes used may vary in price from affordable deodorants to
high-end fragrances while naptha balls are usually cheap. They just offer a band-
aid solution and tend to fade away with time.
2) Water-less toilets: Water-less toilets though proven to provide odorless sanitation
and capable of saving water, come at a steep price. Majority of today's
washrooms cannot be upgraded into a water-less facility without making drastic
changes, thus limiting its usage.
3) Bioblocks: Bioblocks provide a bio-response that is, they release benevolent
bacteria every time they come in contact with urine. The bacteria prevent odour
formation in addition to release of a fine fragrance. Their only limitation is the fact
that they need to be replaced every few days, making them inconvenient.
