Should I choose a hot tub with or without a filter?

The decision of getting a unit with or without a filter depends mainly on how often you plan to use your tub and how much effort you want to make while taking care of the water. 
When no filter is used, you will need to drain the water after every 1-2 uses over 1-2 days. We recommend this option if you are going to use the hot tub only on weekends, when you do not have a shortage of water supply, and do not mind changing the water often (we estimate that water price for a single fill-up will cost around £4).

Our model with a water filter allows you to keep the same water for a longer time (2-4 weeks when operating the filter for 4-5 hours daily and using chlorine-free sanitisers).
