A novel filter system comprising open cell reticulated foam rings compressed between retaining plates and fitted into a filtration housing was evaluated for the recovery of oocysts of Cryptosporidium from water. Mean recoveries of 90·2% from seeded small and large volume (100–2000 l) tap water samples, and 88·8% from 10–20 l river water samples, were achieved. Following a simple potassium citrate flotation concentrate clean‐up procedure, mean recoveries were 56·7% for the tap water samples and 60·9% for river water samples. This represents a marked improvement in capture and recovery of Cryptosporidium oocysts from water compared with conventional polypropylene wound cartridge filters and membrane filters.
