How Odourless by Expella works

Ceiling and window fans only capture toilet odour after it has travelled through the bathroom. The same is true for windows (assuming you have a window); it’s always open, and the airflow doesn’t carry the odour through your home.

You can try to mask the odour with air fresheners, but that just mixes two fighting smells. Plus, spraying air fresheners can be a public admission of something you’d rather keep to yourself.

With Odourless by Expella, toilet odour never leaves the toilet bowl.

Odourless by Expella is a patented ventilation system hidden in your toilet cistern. The system makes your toilet odourless by quietly extracting odour from the toilet bowl and discreetly sending it into the sewer. A nonreturn valve sealed in our odour control device ensures that the smell is gone for good.

Made from injection-moulded plastic, the ventilation system is ultrasonically welded for a perfect seal and long life.

Why “mask” odours when you can eliminate them?

“16.4% of Australians experience health problems when exposed to air fresheners, including breathing difficulty, headaches and skin problems.”

Steinemann, A. (2017).
“Health and societal effects from exposure to fragranced consumer products.”
Preventive Medicine Reports

Making a safer home possible

Most exposure to pollutants that affect health occurs indoors. Air fresheners alone emit over 100 different volatile organic compounds (VOCs), many of which are classified as harmful. Diffusers (plug-in and reed) also release harmful VOCs.

By choosing Odourless by Expella, you save everyone the embarrassment of drawing attention to themselves with an air freshener and reduce the pollutants in your home.

A bathroom breakthrough so innovative they had to update Australia’s plumbing code

Designed on the Northern Beaches of Sydney, Australia, Odourless by Expella is the first system in the world to capture 99.7% of toilet odour at the source and send it straight into the sewer.

The system is so innovative that the Australian Building Codes Board had to create a new technical specification (ATS5200.425, 2009) to recognise the odourless toilets we have made possible.

What our customers say

★★★★★

We are really happy with the effectiveness of the Milu Odourless toilets. We have installed many of these toilets and found them to have quality components that are easy to install. The odourless system works so well, I’ve installed one in every bathroom of my home.

We recently built a new guests bathroom in the centre of the ground floor of our house. Having no windows in the centre of the house we were faced a very difficult and costly solution to exhausting the new bathroom. I was lucky enough to find the Expella odourless toilet. Not only was the exhaust problem solved at a fraction of the cost of the ducted exhaust, we were happy that the architecture of the toilet was equal to the upmarket alternatives. The most impressive aspect of the internal exhaust system is that the odours never leave the pan, unlike normal ceiling exhausts where the odours pass your nose on the way to the ceiling. Yes, clearly we were ecstatic with the solution and the aftersales assistance. So much so that we purchased another toile for our laundry that could have been exhausted conventionally.

I’ve been using Expella’s extraction system in toilets since 2005, and have just started installing Milu Odourless toilets on my residential projects. The quality is of a high standard, which is important to my clients, and the all-in-one unit makes installation simple. No one really wants to talk about bathroom odours, but my clients are always so happy. I almost feel irresponsible not installing Milu Odourless toilets!

For about a year now we have a Milu Odourless toilet from Expella in our bathroom. It’s been a life-changing experience! It has an automatic ventilator that effectively extracts all the odours that you don’t want to deal with in your every day to day life. We also like the sleek, seamless design that’s easy to clean and the seat’s very comfy too!

A clever blend of design and technology innovation brought together to resolve an age old problem. This has the potential for significant commercial impact on the toilet market, particularly in commercial fit-outs that tend towards in-wall cisterns. A potential game-changer for this market. True design innovation that solves a problem and has the potential to make a positive impact on the quality of our lives.

I just thought that I should drop you a line to let you know that we installed the odourless toilet last week and that it has exceeded my expectations.

I couldn’t be happier with it and would be happy to recommend it to anybody considering purchasing one.

Should we decide to sell this house in the future then I will most certainly install another one in any new house that we move to.

Thanks again for all your assistance and professionalism.

Odourless toilets actually work!!! Shout out to Expella bathroom products – we installed 3 of the Milu Odourless toilets (2 back- to-wall & 1 in-wall) and they are awesome. Perfect for open plan bathrooms and the in-wall buttons are quality powder coated metal (not plastic). Customer service has been incredible. Local business based in Cromer who invented the system. Bathroom Collective have a working display toilet so you can see how the magic happens. They also so bathroom ventilation. Highly recommend.

Need to keep your plumber or builder comfortable?

An odourless toilet will bring you years of comfort, but sometimes builders and plumbers need to be made comfortable, too. You might find that your builder or plumber wants to use a toilet they install all the time, even though that toilet won’t give you the years of odour-free bathroom enjoyment you’re looking for.

You can assure your builder or plumber that Odourless by Expella is a patented addition to a standard toilet. This means that installing an Odourless by Expella toilet is the same as installing any other standard toilet. All that’s required is power for the ventilation system, which your electrician will have no trouble providing.

In addition, Odourless by Expella is fully compliant with Australian Standards and the Plumbing Code of Australia. (We know this because we worked with the Australian Building Codes Board to add Australian Technical Specification ATS5200.425 (2009) to the plumbing code specifically to recognise the innovation behind Odourless by Expella.)

As well as providing you with our easy-to-follow installation guide, we’re happy to talk to your builder or plumber if that would be helpful.
