Convert your 4-filter TidalFit to Ego3: 4 pre-filled cartridges, one for each filter well.
Guaranteed to fit TidalFit Swim Spas — match the pack to your spa’s filter count. TidalFit models use 2, 3, 4, 5, or 6 filters depending on model and single/dual temp configuration. Count your filters (large 6.75″ EZ01 and small 6″ circulation EZ02), or send us a photo and we’ll confirm the correct set before you order.
Ego3 filter cartridges come pre-filled with filter media. Once converted, you never buy filters again — when the media is spent, pop the canister open, drop in an Ego3 refill, and you’re done.
