Microban filter # 8553 (2009+) for Softub Spas

Exactly what i asked for. Great quality

Fits perfectly

We needed a new filter for our Softub, so I selected this filter since its filtration element is made of antimicrobial material. The old filter was a bit difficult to remove since the base ring had apparently hardened a bit from constant exposure to the warm chlorinated water. However the new filter slipped on easily. Of note was that this was apparently due in part to the base ring (and end cap) having been lightly coated with what appeared to be a silicone lubricant. The filter was effectively sealed in shrink wrap from the factory, and our original pre-filter sleeve (which I was able to clean and reuse) fit perfectly.

As good as the Regular Filter with the Frog

I have the big soft tub that was purchased in Oct 2010. At first I used the regular filter with The Frog and then 2 years ago switched to this filter. Decided to experiment and the first year I used it with The Frog and then this past year without. Can't say I noticed anything different without The Frog, other than using a little more chlorine to compensate for no Frog. I use the tub daily - here in the midwest ambient temp of -15 F to 105 F. In the summer I keep the water temp about 94 - 96, however. In terms of water clarity, foam, pH, etc. I haven't seen any difference in the amount of chemicals used. I do add Water Clear weekly and change the water each spring and fall.
