Whole House Water filter - Good idea to switch from regenerating salt based water filter ?


Hello folks,

Considering to replace our water filter system, which currently filters water for a small house with three apartments. This system uses Regenerating salt bags for purification. We consume around 300 cubic meters of water per annum.

Current system works reliably but fed up with purchasing loads of 25 kg salt bags for regeneration. I heard there is a new technology which uses oxygen cylinders instead(reverse osmosis)? Looks like you ay need to replace the cylinder once a year or so? How reliable are they? It is a good idea to shift from salt based water purifier with reverse osmosis technology?

1.Does somebody have experience with such whole house water filter system?
2. How relatable are they?
3. Which model/make would you recommend?
4. Any installer who can install this in Brussels?


Not sure why you think it's necessary to filter or soften the water, but if you really do want to "relate" (sic) better with your water supply, find out more about the various options out there, and to answer all your questions, go to Batibouw 2020. Every major company supplying water softeners / filters in the Belgian market will be present. It's at the end of February.

I wouldn't bother unless you have plenty of spare cash you don't know what to do with. There is a reason why traditional softeners are extremely popular - they are cheap to run, and they work very well.

Our old system consumes around 50 Kg of salt per month. Also wastes 10~20%. water for regeneration, say around 30 cubic meters per year, total water consumption around 300 cubic meters per annum.

Lugging 24 bags of 25kg salt per year also adds transpiration cost, creates storage issues etc.. Yes, It has been tested and certified to work excellent recently.

Not sure if this is normal/abnormal?

We have a water filter which requires regular refilling with salt. For the reasons given here, we stopped refilling it recently. Does anyone know if this could give rise to problems?

Q - "Does anyone know if this could give rise to problems?"
A - None at all. Water will just pass through it without getting softened.

Long term, if you're stopping using it altogether, probably best to get a local plumber to come round and disconnect it. Or you may be able shut it off with an existing bypass circuit.

Yeah - the resin thing will clog up and stop working.

Personally, the unfiltered water makes me come out in blotches. I can tell immediately when our thing needs refilling.
It also keeps appliances like the washing machine and kettle from fuzzing up, and the tea tastes better with softened water and you don't get a thin layer of scum on top.

We consume in the region of 150kgs salt/year.

Oppressed in Oppem, the only consequence is that your water will be filled with calc, and your washing machine, boiler, dishwasher, etc will all perform much less efficiently and need replacing more quickly. You'll also need to use far more soap to wash with, and your hair will turn to steel wool :-)
