There is a way of finding out the percentage of filter that is still available at any time. Go to Main Menu by pressing the right hand arrow. Then scroll down to Filter Details. Press the right hand arrow again and it will tell you the percentage. Ventis will tell you that once this figure goes below 20% you need to change the filter. They don't explain why. I am unable to replace a filter myself so have to pay approximately $200 once a year to maintain this supposedly "cheap to run" system. It's a good regular money earner for the company! Although I have found service to be efficient and technicians punctual, my experience with the system is like many others - it just doesn't do what it is promised to do. Very disappointing.

I was not initially impressed with the product, or the customer service I had experienced in the past. However, after recent telephone contact and a subsequent visit from Gary from Ventis, I have changed my mind. Gary showed a genuine interest in the issues I raised, and worked with me to deal with them. He also explained the workings and benefits of the system, and how to operate it to gain the best results. I now feel that the system is a worthwhile addition to my house.

I bought my system in January 2015.When the filters needed replacement Ventis were in receivership so I sourced filters elsewhere at $42 each.I was recently contacted about replacing filters again but the same filters from Ventis are now $99 each and the company I sourced from last are now prevented from selling to me by Ventis.This system is useless in Australian conditions and only during winter can some use be made of roof cavity heat.I have made some bad decisions in my life(69 years) but this has to be one of the worst.I wish they had stayed in receivership and saved other people from making the mistake I made.Do not buy this system!!!!

I have never written one bad review. This is the first. I recently had a Ventis serviceman change the filter on my Ventis system. I had booked in a service for the main purpose of an explanation as to why the vents do not blow anymore and how to use the system properly. When he arrived he changed the filter and told me he had no time to explain why the vents do not blow, it is an older model and he has no idea. He told me to look on the website which of course does not explain anything. He was unhelpful did not have any time to even show me how to use the system and seemed irritated for my asking this.
The main reason for the booking was to explain how to use it so I could understand it.
Unimpressed.

Turned it off it is as useful as an ejector seat in a helicopter. If having smoky air sucked in and distributed throughout your home is what you want, particularly in winter when there is so much inversion around from polluting wood heaters well go ahead and blow your hard earned money on one of these systems. Since moving into our new home with this Ventis system both myself and my wife have developed constant coughs and throat irritations. We have never had any problems previously now we are regretting buying this home. Particularly with all these irresponsible polluters in the neighbourhood, wood fires should be banned totally.

I have a Ventis system installed in my house, when it works well life is good. But having to deal with this company when there is a problem, one big nightmare. Missed appointments, no communication, multiple invoices issued of different amounts for the same job, e mails not returned, lost my entire fan motor when they took it away for servicing, extended warranty is not worth the paper it's written on and poor record keeping. My advice would be to stay away from this company. They clearly have no idea what they are doing.

We had a Ventis system installed two years ago. The system worked well for a while, but the fan has now stopped. We have been told that we are out of the warranty period and the only solutions are to get a rebuilt or new fan, at a cost of between $600-$900. The initial purchase price was over $3,000. We would not recommend this system as it is expensive and unreliable. It is a pity as we enjoyed the system while it worked.

Had this system installed 2 years ago. The fan is not much better or stronger than in a portable 2 settings heater. The included filter is of a very cheap cardboard framed unit with a rough fiberglass mat, It was promised to have a pressure differential switch to show filter element condition. However it only has a timer which after a year (even when hardly ever used) indicates filter has to be replaced. As we are pensioners and do not venture in to the roof space anymore cost of replacement is over $100.00. System should not get a star at all !
