The apartment that we're living in has very hard water, causing very itchy scalp for myself and tangled hair for my partner. We've bought and installed a shower filter previously, and it worked pretty well for a few months. Now that we want replacement cartridges though, it seems to be very difficult to obtain and/or expensive.
Anyone have any recommendations for shower filters that work well, and have obtainable cartridges?
We have used sprite shower filters in the past the cartridges are about $50 - $60 each https://watershop.com.au/product-category/water-filter-syste…
