small unicel cartridges

I'm looking for the "better" cartridges suggested for the intex pools and the ones linked to on this site are both larger than the cartridge size on my filter - they are either 8 or 10 inches and mine are around 4-5 in. Does anyone know if this is correct?

These are the unicel ones, but I'm not sure if it would fit because it has a cone on the end cap, which the cheap-o-ones my filter came with do not have. I thought I would check here before I purchased. Thanks!

Do you have the intex size "D" filters? I do not believe that Unicel or Filbur have ones in those sizes (I've been looking for them for my SIL who also uses the size D filters)

Ah, yes that is what we have. I guess we'll stick to the intex ones.

Check again for Filbur and Unicel.

I just checked (heaven forbid!) the Pleatco site, and they seem to have a cross reference to Unicel C-4313, and Filbur FC-3753.

Check your filter size (measurements). Are they 4-1/4" diameter, 3-3/4 long, 2-1/16 top and bottom holes?

Why didn't I think of that, lol! Thanks Charlie_R!

bellini - I checked on Amazon, and all 3 of the products listed as the Unicel c-4313 are pleatco's or another substitution. It does look as though Amazon sells the Filbur FC-3753 (2pk for $15.35 - although the picture doesn't look like a Filbur, the description says it is a genuine Filbur). The other one for Filbur says it is sold externally through Filters Fast (2pk for $9.97 + $5.97 shipping) and on their website they say they are genuine Filburs as well.

I'll pass the info on to my SIL so she can order some for her pool, best of luck to you on your pool as well!

See, this is what makes Pool Forum great. Pool owners helping pool owners! Thanks 7sanders and Charlie_R!

Got 'em - thanks!
