Your spa filter system was designed to work most efficiently with this
25 or 50 square foot heavy duty Unicel filter cartridge. While routine
cleaning can extend the life of your filter cartridge, algae, suntan
oil, body oil and other contaminants will rapidly clog the tiny pores of
the filter membrane which drastically reduce the effectiveness of your
filter. We recommend cleaning your cartridge twice a month and replacing
it every 3-4 months.
This filter cartridge is not intended for use in any other spa filter
system than the Waterway brand Top Load or In-Line Spa Filter System
we sell. If this is not the filter system you have, click here.
The dimensions are 13 1/4 inches tall, 5 inches outside diameter, with a
2 1/16 inch center hole.
This item is not returnable, and carries a 90-day limited warranty.
