Unicel Cartridge Filters?

[longshot]

I'm looking to get a second filter for my Jacuzzi J-210, and I found an online store that sells Unicel brand filters that appear to be made as replacements for the OEM filters.

Any thoughts on these? Price is about half what the OEM filter costs. Thanks.

Unicel makes fine filters.  They make a lot of the OEM filters that you see on the market for both hot tubs and swimming pools.

I have 2 unicel filters that I rotate, and have done so for a year. They look and feel like new still.
