Pre Filters Advice For RO van system

[maxiswindies]

I have 4040 RO set up with Di vessel and two 20 inch pre-filters. Would like to change the pre-filters as part of maintaining the kit. Can someone suggest the best place to get the 20 inch filters as a set? Are there any videos on the forum to show how to do this. I'm confident but like the forum for these type of resources. I would think I need the carbon filter and the normal sediment filter. Any help would be appreciated. Thank you.
