Current Stock:

Vision is an excellent alternative to conventional sanitizers and offers clean, clear water without the harsh chemical smell, red eyes, bleached clothing and dry skin. Its silver catalyst technology kills 99.96% of pathogenic bacteria on contact. Vision is easy to install and lasts a full six months. It now features a convenient "Installed/Replace" Reminder Ring.

The Vision Cartridge System:
The Vision Cartridge is manufactured by Dimension One Spas, Inc. The new Universal cartridge replaces the following products: from Dimension Pure Vision cartridge, Ultra Vision Cartridge, Crystal Vision System-Complete, Crystal Vision Cartridge, Crystal Vision Basket and Crystal Vision Lid.

What is a Vision Cartridge?
Vision is an alternative sanitizing system that is used with your spas water management system. The advantage of Vision over conventional sanitizers such as Bromine and Chlorine is that it will provide softer-feeling water as a result of lower overall chemical use. Also, fewer chemicals results in lower total dissolved solids (TDS) which means less spa maintenance.

How a Vision Cartridge Operates:
The Vision Sanitizing System has no moving parts and requires no electrical connections. It contains a powerful, Silver Nitrate catalyst bed with a large surface area. Water circulates through the Vision Sanitizing Cartridge, through the filter, through the heater and finally returned to the spa. When used with a a Water Management Systems and a Chlorine base, Vision provides a soft, residual bactericide that compliments the oxidizing power of ozone and the sanitizing power of Chlorine. Refer to your spa's owners manual for proper guidance on pH, Total Alkalinity, and Calcium Hardness levels. These levels must be properly maintained for adequate spa water balance.

Used in Spas of all types
Even thought the Vision Cartridge is manufactured by Dimension One Spas, it will fit in most other spas as well. This vision cartridge should fit in your filter area or  skimmer basket with a minimum of 5 inches of space. This Vision Cartridge lasts 6 months versus the the 4 months Nature2 Spa Purifiers, and Spa Frog S Purifiers.

  • Crystal Pure (Models 1989 - 1996)
  • Crystal Zone (Models 1992 - Current Year)

    We have an older D1 spa and have used the vision cartridges regularly for 15 years. They work well at keeping the water clean and fresh
