Welcome to our forum.
My '05 maxxus is going on 6 months & I have not had any problems W/ my filter. My dealer told me that the filter was good for only 6 months. How long are they rated for? (based on average usage). On another note I finally received my steps & the color match & quality is very good.
The filters are not rated for any length of time. The Microclean II filters are generally supposed to last about 6 months, but it depends on the amount of use the spa gets. The more use the more replacing. If it was my spa, I would replace it about every 4 months when the spa gets drained. I have not read or heard anything that would tell me the filters are supposed to last a whole year.
If your dealership is charging $100 bucks that seems to be a little high to me. They should cost at most $75 bucks.
I am going to change my opinion. I think $80 would be a fair price and give the dealer a very fair margin. At $100, I think the margin is pretty high.
