    Customer Testimonials


    I purchased the benchtop 12L filter, and it’s just what I needed. It removes all manner of bad content and adds in the good stuff, the minerals, and you can’t taste anything. It tastes like fresh water. Better than the bottled stuff.

    At first, even after emptying out one load as per instructions, it tasted horribly like sucking on a wet terra cotta pot (well how I would imagine it), but I emptied the batch out and filled it up again, and it was perfect. Just needed that one extra flush.

    On-going, it’s easy to use.

    Water filter was easy to fit. It’s the first time we’ve had one after being told to get one by my son. I can honestly say that the water definitely tastes better & of course we know the health benefits. Highly recommend this product. Thanks. 

    Dear team at My Water Filter,

    What can I say.. Thank you. Thank you, for your professionalism through the purchase and delivery stages. Thank you for your extraordinary product. I could not be more happy with the purchase I have made with The Whole Home Filtration system.

    I have immediately noticed a taste difference in the quality of water and my body is responding to it in a positive way. I look forward to drinking water so much more now. My family all agree that it was a sound investment. All of our healths will benefit from the installation.

    What else can I say..

    Thank you.

    Hi Rod,

    I am very pleased to be able to give some feedback. I am extremely pleased with the above counter reverse osmosis water filter, which was only $285.00. I didnt need to do any plumbing to install it and Rod talked me through how to install, which I did myself! The water tastes delicious, so pure and easy to drink. I am very pleased I can now filter as much water as I need every day. So far I have been filtering 6 litres per day and I am drinking more water now, which I am noticing is helping me!! Which is so much better than buying water in plastic containers! I estimate this unit will pay for itself in 10 weeks if you currently buy water, which I did.

    Thanks Rod, A great product.


     I am very happy with the customer service provided by Rod. He is so helpful and efficient

    I purchased the free-standing stainless steel gravity filter to replace bottled water I was having delivered.

    The water quality and taste is excellent, so I'm glad I made the switch.

    Some written instructions on assembly and first use of the candle filter would be helpful as we were drinking chalky tasting water for a few times, not realising the need to flush it more than we did.

    After-sales service was excellent and we were quickly in business.

    The candle seems to build up residue on the outside quicker than expected but it is easy to clean and well worth the effort.

    Thank you My Water Filter!


    I'm blown away by your whole teams level of customer service I really appreciate it and will definitely let you know how it goes either way :) Leah

    Hi, I ordered a benchtop filter and received it one week later. Very pleased with the beautiful workmanship and outstanding quality of the product. Best of all the water surpasses the freshness of the 10ltr boxes I was buying no more lugging around 10ltr boxes and having to dispose of the waste after.... so much more eco-friendly.

    Many thanks Cheryl

    Hi Rod and Team,

    We just ordered our first water filter through your online website and received it at the address we provided within the 3 to 4 days you estimated the delivery. Great Service and the whole ordering experience was very easy. We will certainly be using you guys again and will also be recommending you to friends!


    It has only been 3 days since I installed our whole house water filter. The difference has been remarkable. My wife and I have both noticed how soft our hair is and the water feels nicer. We have told friends and neighbours about the filter and I know you will be getting more business.

    Thanks heaps
