These are in my Bi monthly filter rotation for my hot tub! works great and the price is affordable for the amount of use i get out of them!

Fit perfectly. Will definitely buy these again.

Keeping my hot tub clean.

I have used these filters in my hot tube for years, They are very durable and can be washed out for a year or more. Great value for how long they last.

Did as expected ,price was good so far to early to tell.

Product was what was described at a reasonable price.

Fit well and work as designed!

Good but damn expensive

Inexpensive alternative to the brand names. Just replace them instead of clean them, work great!

Parfait pour mon jacuzzi

They are perfect. Exactly what we wanted.

Dure facilement 2x plus longtemps que le filtre d origine avant de nécessiter un grand nettoyage par trempage . Très satisfait.

Work well as a replacement but the original had more pleats and therefore filtered a little better. You just need to change them more often.
