These work fine in my Healthy Living HL-7 hot tub (and most likely the entire HL series). The recommended filters sold by the spa supply companies are far more expensive, and I have my doubts about the very expensive mineral filters.

La altura del filtro es 1-2 mm más alto que el original de Endless Pools y hay que rebajarlo con una lima para que cierre la tapa, el resto OK.

Perfect fit for our Nordic spa. Much more affordable than buying from our local spa supply store. Works great!

This worked perfect for my master spa. Half the price and exact same filter.

After several attempts I have found a filter that works with my spa and I can order them as needed. The " dealer" that I bought my spa from never has the correct filter in stock. Thankfully Amazon does !!The filter fits well & has the correct micron range & is built well enough to be able to wash it out & reuse it.
