Pentair cartridges are superior to other ones I have replaced with. Inyo was the only firm I was able to directly order from that supplied me the Pentair cartridge replacements.

Pros: durability/performance
Cons: price
Altho pricey compared to the competing brands, Pentair original equipment filters are worth it. Outstanding performance by these filters.

Have used Pentair from Inyo ever since I first replaced cart. filters in 2002. Usually last 2 seasons with 1 or 2 clean-ups. Best deal out there
