Clarathon 2-Pack Spa Filter Replacement for Sundance Microclean 6540-502 FC-2812

Bought this two pack of spa filter replacements for our Sundance spa. My plan was to buy a two pack and compare performance between the Sundance OEM ones (that my local spa shop sells for $16/each) and these. After using one of these and comparing its performance to the OEM ones, I can report that I have noticed NO difference in performance. The filtration performance and lifespan are at least extremely similar, if not the same. I plan on using these in the future as they have proven themselves to be of similar quality at a significantly cheaper price.UPDATE: After a longer sample size of these filters was tested (about five or six filters over an almost two year period), I am deducting a star due to noticing that these filters are slightly less effective as the weeks go by than their OEM counterparts. They still work fairly well, but a difference in performance is noticeable. Bottom line, if the OEM ones are not much more expensive, stick with them; if there is a significant price difference, these will be effective so long as you keep on top of them and change them out a bit more often.Hope that helps.

Good value for the money. No diff than OEM for a lot less

Perfect and exactly what I needed love the fact that it comes in a duo pack.

They fit perfectly, and they were a great value.These worked out great for us!Quality seemed similar and lasted just as long as the previous name brand filters.No issues.... so 5 Stars!

Fast shipping filters work well

Works as advertised.We bought these and lasted just as long as the factory ones we buy from the spa store which are twice the price.Just keep your tub clean and at the right fluid levels and these will last.

Easy to install and appear to work as well as recommended manufacture but at a fraction of the cost.

This is an item we continue to reorder. Fast easy and good price

Excellent works great

very pleased with quality, value, and price!
