We recommend having two sets of filters for your hot tub as this allows for proper cleaning.

Your filter needs to be fully dried before placing back in your spa, therefore a spare set allows you to do this without interrupting your hot tub usage. 

Your filters should be replaced every 6 months for maximum filtration. Free filters with every full service.
