NEW Shower filter with patented KDF-55 media

You might ask why we have this new shower filter when we already have a very successful range.

The old adage that "shower filters ain't shower filters" applies in this situation - I’ll do my best to explain.

New regulation in Australia means that hot water systems now should have a tempering valve to regulate the temperature of home hot water, to avoid children scolding themselves.

The problem with these tempering valves is that they were never designed to handle pressure variation - they are first and foremost a temperature regulator.

There are some very good quality shower filters on the market that work extremely well - most of the good brands have a larger quantity of KDF media and less carbon, due to use in hot water shower situations. KDF is a media made primarily from copper and zinc which are the two heaviest and most dense metals in the world. Because they are metals and don’t wear out, they produce a kinetic reaction that has the effect of neutralising Chlorine to very high standards.

What can exhaust a KDF filter is a build-up of materials that bond the two metals, which slows the kinetic reaction - and in some cases, less favourable water ends the life of KDF fairly quickly.

Not only is KDF heavy and dense, but it’s also one of the most expensive filter media in the world - and unfortunately it’s needed in hot water situations.

I can’t speak for all the systems on the market. But our experience with most of the more expensive brands that use a lot of KDF (apart from being very expensive), is that they are also very dense which places a high degree of back-pressure on the hot water tempering valve.

The result of this can be the inability to stabilise the temperature of the water under the shower. In short, the tempering valve becomes confused and continues switching from hot to cold, which isn’t a pleasant situation when you are in the shower. I have had personal experience with this, to the point my wife insisted I remove the shower filter completely…  So I removed the tempering valve instead. Because I’m chemical intolerant, I need the shower filter more than I need the tempering valve.

I then set about finding a shower filter that didn’t create too much back pressure, and these are our current White and Chrome plastic shower filters. These have served us well for a number of years, but the downside of these shower filters is that they have more carbon and less KDF, so they don’t last as long in hot water as the more expensive brands that use more KDF and less carbon.

But the upside is that we have never had a back-pressure issue since changing to these filters and all we do is change the cartridge at 2-4 months rather than 6-12 months.

Now we have this shower filter which has the “more KDF” and less carbon, coupled with the low back-pressure. It’s taken some time for manufacturers to get the idea, but we are somewhat over-regulated in Australia with plumbing standards and I suspect these issues haven’t been too well known overseas.

So it’s all about choice now, we have the cheaper shower filter with a shorter life, or this new shower filter with “more KDF” and longer life (and also a low back pressure rating).

Whichever way you choose, we have it covered, but for my recommendation based on being an end user that relies on chemical extraction, I highly recommend you pay a little extra and use this filter for longer life, less back-pressure and a higher level of chemical extraction.

Fits to an international standard shower head.

Replacement Filters

Cartridges can last 2-6 months depending on water quality and usage volume. To replace your cartridge simply turn off your mains water supply and unscrew the shower hose from the filter. Take off the outer casing pull out the old cartridge and put in the new one. Then screw the casing back on and screw the shower hose back onto the filter.
