How long/what size filter?
The larger the capacity of resin the longer/more rinses you will get.
The harder the water the shorter life the resin will have as it has to work harder to de-ionise.
So all filters will do the job but depending on the water hardness, the number of rinses & volume of water used will determine how long the resin will last.
The larger the cylinder, the less frequently you will have to replenish the resin.

As a general rule water is considered soft if total hardness is less than 75 ppm, moderately hard at 75 to 150 ppm, hard at 150 to 300 ppm, and very hard at 300 ppm or higher.

    Our advice

    Perfect for the home multi wash user, giving very high filtration to stop water spotting & streaking, whether left to naturally dry, by towel or Blaster Dryer. We recommend rolling the cylinder once a month to keep the resin mixed to give best results. Portable or use our wall/steady bracket.
