To keep the water on your Intex PureSpa looking its best, you will need to periodically purchase replacement Intex Pure Spa Filters. There’s nothing worse than getting ready to climb into the hot tub for a relaxing session in the bubbles, only to find that the filters are clogged and the water feels disgusting.
Also, be sure to regularly vacuum your hot tub to keep it clean as long as possible!
Intex hot tubs are great products, and require very little maintenance over the course of their lives. However, ensuring you have the right Intex Pure Spa Chemicals and the proper filters are key to keeping your water clean, clear, and ready to soak in.
Intex Pure Spa Filters
All of the Intex PureSpa hot tubs use the same format for the filter, the Intex S1 Filter system. This makes purchasing replacement filters very simple. These units are sold in several different quantities, from two unit packs to the cost-saving bulk 12 pack shown here.
Depending on how frequently you use the tub, how often you change your water, and the source of the water you use in your tub, you’ll need to replace the filter more or less frequently.

Intex Spa Water Treatment System
The Intex Pure Spa water treatment system has a built-in hard water removal stage, which is a great bonus not found on many other brands of inflatable hot tubs.
Hard water can cause irritation on the skin, on bathing suits, and even can cause damage to the hot tub’s mechanical systems. Due to this hard water issue, Intex created an electromagnetic filter system to remove unwanted minerals and chemical compounds that harden water.
Intex uses an electromagnetic field to agitate calcium and other minerals present in the spa’s water profile. The agitation suspends these crystals in the water, as opposed to keeping them attached to various surfaces. By suspending the crystals in the spa’s water, the minerals will flow through the pump, and through to the filter system.
From there, the water filter does the rest. The filter removes any suspended minerals and crystals floating in the water, and the water is left soft, clean, and clear. It’s ready for soaking and soothing!
We have the inflatable intex, one filter is alway dirty and the other is clean. There is no water flow thru the filter that is the furthers from the pump. the on next to the pump work fine. What could this mean?
