Bottom line: use fine media for fine, settled debris
NanoFilters™ are pleated media intended to retain smaller material such as fine dirt, silt, pollen, and settled dead algae. Results depend on particle size, filter condition, flow, and how often the pool is cleaned; the robot does not replace balanced water chemistry or the main circulation system.
Included and compatible are not the same
Some current Quantum, Premier, and Sigma packages are with NanoFilter™ media, while compatible media for models such as the Cayman may be sold separately. Product names and feature labels do not guarantee compatibility. Verify the current product listing, manual, and filter part number before ordering, especially when comparing value-oriented options.
Use coarse and fine media deliberately
- Remove large debris first or use coarse media or a leaf-focused option during heavy leaf season if the model supports it.
- Rinse pleats before packed debris restricts flow, following the manufacturer's cleaning directions.
- Inspect seals and seat the filter correctly so collected material does not bypass the media.
Pool compatibility still comes first
Fine media does not establish whether a cleaner fits your pool. Make sure rated dimensions, surface guidance, cleaning zones, cable or runtime limits, and whether the selected media is included with that exact model version.
