4 Pack for Hayward Sharkvac Filters RCX70101PAK2 Replacement Pool Filter Cartridges Compatible with Hayward Robotic in-ground Pool Cleaners AquaVac, TigerShark and SharkVac

You get two pairs for the price of one Hayward branded filter. The filter material is different. It feels different and is more stiff compared to a Hayward branded filter. But, having run a few cycles now with the filter, it does seem to work. The only question is whether this will last a season or not. I will have to update this review after some time.

This is a superb set of filters for the Hayward TigerShark pool vacuum. They fit and work perfectly in the TigerShark. You only need two at a time, so four should last for a very long time!Quality seems excellent. They filter very efficiently and are very easy to clean.Finally, kudos to the manufacturer, seller and Amazon for making such a great and useful product available at a very fair price!I will update this review if needed based on further experience.
