Filters, ??????????????

[Mr B]

I have a stack of filters for my water systems, Including the watermaker,
They have no marks on them any where except the manufacturers name,

How do I tell what grade filters they are, 5 microns, 20 Microns, Etc,
They do have a red and a blue line around some,
The others have nothing on them at all,

Thanks Brian,

First, I wouldn't use the opened charcoal filters for your watermaker. They looked previously used, thus not safe for a watermaker.. The other two filters are color coded. The lighter blue one should be a 20 Micron where the darker blue is probably a 50 micron. But I don't recognize these filters, they could be special purposed filters such as oil/water separators etc. Watermakers are expensive, filters are cheap, I'd start with new to be safe.

Thank you,
I took them out of the sealed plastic bags to take a Piccy of them,
They came with the boat and have been sitting on the shelf for years,
The filter bowls were set up before entering the pressure pump of the water maker and before the freshwater flush for the water maker, ,

My watermaker requires a 5 micron filter, So these arent suitable any way,
I also changed the 110 volt motor and pressure pump for a 240 volt pressure washer and hooked that up to the watermaker instead, It works perfectly,

The 110 volt motor was cactus any way, $90-00 for a complete pressure unit against $1100-00 for just a new motor,
If it dies, I will just put a new 240 volt, $90-00 unit back in,
Just a pressure pump replacement is $90-00, Plus fitting,

Cartridge Filtre Element Colour Coding:
Generally, manufacturers colour code the plastic end caps, if at all (not stripes on the element).
I haven't noticed any commonality of colour codes across different manufacturers.

This is true, but most manufacturers are catching up with the common color codes of yellow for 50 Micron, blue for 20 Micron, and white for 5 Micron. But not all companies do. Not sure about the stripes as well.
