for those of you that have a bestway or Intex swimming pool and use those blue and white filter cartridges, at your own risk you can try the following as I needed a filter and my stockist Espace Maison had run out if the III size.
I re-cycleed the filter by using a nylon dishwashing brush by carefully rinsing off the debris and the brushing in-between the fold of paper carefully not as not to split the paper type material. I then rinsed it again and it almost looked quite new so I tried it again in the filter and it worked and collected the similar debris etc as before when the filter pump was switched on. I guess that if the filter is not too soiled you can clean it up and use it again so as to get more than one use out of it . Of course I now have some spare filters which are waiting to be used but my recycled one is on its fourth use now. I think I should give the filter an end of life after 5 usages but if it does the trick for five times then I have saved the cost of 4 filters and also saved the environment by not having 4 more pieces of plastic to dispose of
