Perfect
Saw the negative reviews on this filter, but at this price was willing to take a chance. Even if it wasn't the one advertised, it was better than what I had and was much cheaper than the 89 dollar Watkins filters I had been buying. When it arrived, it was a Unicel filter just as was advertised and the thing I liked best was the big, Made in the USA label. It was cheap, and one of the better filters on the market. Arrived in two days and is now cleaning the water in my hot tub. I will definately order again.

Identical to the Manufacturers
Today we opened the hot tub after it was closed for the winter. We cleaned the hot tub, emptied out the antifreeze and filled the hot tub. Then it was time to add the filter and the chemical. The filter did such a great job (and the chemicals) that I had PERFECT numbers on the hot tub testing strip. This hot tub filter is the correct size and fit just as promised. Could not be more pleased. Try it, it works!

Quality
This product is made with quality fabric and rubber materials. It appears to be the same product that was in the hot tub when we purchased to home. With regular cleaning the previous filter was at least 4 years old ( likely older ). I would purchase this again.

Good filter quality
I was leery of an off-brand vs Watkins, but is is holding up actually better. I’ve been using for 8 mo, and usually the other brand shows wear around the center ring that holds the fabric folds, this filter has not shown that typical wear. Pleased this quality and will purchase again

Great value and product
I try to shop locally, but the value and price of this item is such a good deal that I had to buy it through Amazon. It is identical to the one we purchased in the past at our local store for twice as much money, which is significant. Our hottub is as clean as can be with this replacement filter.

The price is great but I find with this unicel filter causing my tub to trip. The indicator indicates that the flow through the heater is insufficient. When I put in my pleatco one, no issues. If you look at the inner tube, the unicel has small 1/2 inch holes spaced out whereas the pleatco one is like a cage inside with much more flow.

Product was as advertised. Very pleased with quality. Went to order a spare but now does not qualify for prime free shipping. Will just go to local store for same final price.
