2 Pcs Cold Plunge Filter Scum Absorber, Ice Bath & Cold Plunge Accessories, Reusable Ice Bath Tub Filter Oil Scum Balls Floating to Keep Water Clear, Cold Plunge Water Filter, Ice Bath Water Cleaner

Does the job

Crap- had high hopes for these but didn't absorb anything at all

Helps to keep the tub cleaner

They arrived late, they haven't changed anything in my ice bath what so ever, I don't think they are doing what they claim to do. They're are just floating around like unemployed soft balls, I'll give it a little bit more time and see what happens. Would I recommend this product, well at the moment I wouldn't as nothing is happening in my ice bath.

These work great!

Do not bother. They do not collect any oils and such from cold plunge. Waste.

I used a hydrogen peroxide solution and place a capful between plunges. I noticed a huge difference and that water quality would last much longer when paired with the scum catchers, and seem to get a lot more out of each change. Easy and recommended!

I am filling my cold plunge with rain water, which means more scum much faster. But not really the human scum, more like the natural scum. I put these in right away, but honestly don't think they did anything... hard to say though.. anyways they are still pretty white and I would believe they'd turn yellowish if they actually absorbed something. Seems quite gimmicky.

Seems to work. They are simple but my bath has stayed clean and clear for well over a week now. Easy to clean and reuse to keep the cleaning going.
