The X10 Water Filter will eliminate many water quality problems in a hot tub.
The tap water, well water, and lake water used to fill a hot tub is probably not as pure as you think. Impurities such as copper, calcium, sodium, iron, mercury, and other heavy metals can be harmful to bathers, can harm your spa parts and make it harder to balance your hot tub water. These deposits can seriously harm your heater element, jets, pump and spa shell. These deposits will also make it difficult to balance your spa water and can impair water quality.
The X10 Water Filter is a spa pre-filter (hose filter for the hot tub) which can reduce and eliminate rust, organic debris, turbidity, bad taste, chlorine, sulfur, odours, aluminum, iron, mercury, and other heavy metals.
Instructions: Attach the spa pre-filter to your garden hose and run the water through the filter for 30 seconds before filling your spa. Replace when the spa pre-filter is full and flow becomes restricted. The X10 Water Filter is guaranteed to filter a minimum of 10,000 US gallons (37,854 liters) of water.
