Pura Stainless Steel UV Units
Highest Quality Stainless Steel Ultraviolet Water Purifiers from America's Top UV Manufacturer
Pura's powerful new stainless steel ultraviolet units come in three sizes, each with higher lamp intensity and higher flow rates than the comparably sized traditional plastic Pura systems. The stainless units each feature LED display with sophisticated visual and audible alarms. lamp change reminder, and countdown lamp timer. They also are available with an optional lamp intensity monitor that provides a constant reading of the unit's UV dosage intensity. These are versatile units, easy to install, easy to maintain, and easy to adapt to numerous applications.
Each of the stainless units has an easy-to-read monitor that reports the lamp's remaining service life and warns of lamp failure. The stainless units are trouble-free, user-friendly systems that feature the latest in UV techology.
Here are some leading features of the new stainless units:

To understand the differences between the conventional Pura units and the new stainless units, it's necessary to talk a bit about how UV dosage is measured. UV dosage is typically described in units called "Joules," and it is most frequently expressed in terms of "mega Joules per square centimeter," or mJ/cm². (Microwatts per second per square centimeter, expressed as µWs/cm2, and mJ/cm2 represent the same dosage and are used interchangeably.) The higher the number, the higher the dosage. The UV dosage increases as the flow rate of the water being treated decreases, so a UV unit that puts out a dosage of 16 mJ/cm² while treating water at a flow rate of eleven gallons per minute (gpm) will be rated as 40 mJ/cm² if the flow rate is decreased to 4.5 gpm.
NSF International believes that a UV dose of 40 mJ/cm2 is the minimum UV dose required to ensure that all bacteria, viruses, Giardia and Cryptosporidium are killed or inactivated to a safe level. However, for practical purposes, much smaller doses are usually regarded as adequate. The most common concerns, e Coli, Giardia, and Cryptosporidium, are effectively eliminated at less than seven mJ/cm².
Pura's stated gallon-per-minute ratings for its stainless models are based on a dosage rate of 30mJ/cm². In other words, the UVSS-6 has a 30mJ/cm² rating at a flow of 6 gpm. As the table below indicates, there's a significant margin of safety built in. (The conventional plastic Pura units are rated for a dosage rate of 16 mJ/cm², so comparing the two systems can be tricky. A Pura "Big Boy" series plastic unit, for example, that is rated for 16 mJ/cm² at a flow of 15 gallons per minute, has a much higher dosage rate at normal residential flow rates.)

Pura stainless units are tough, durable, easy to install, and easy to maintain. Pura stainless units are divided into regular units (designated SS) and monitored units (designated SS-M). The monitor is an intensity monitor that actually provides a reading of the current intensity of the UV lamp. Since it's a high tech instrument, it's expensive.

One strong feature of the traditional plastic Pura ultraviolet units is that they're sold with optional
|2.5" X 20" and 4.5" X 20" cartridges fit the housings above.|
Pura's stainless units are sold as UV only, so we've added some filters from our regular stock to supplement them. The cartridge filters listed later on this page are identical to the filter housings on the original plastic Pura filtration systems. The purchaser can, of course, use the stainless unit with an existing filter or add his own filtration from another source to the stainless Pura system. With UV, unless the water is very clean, it's necessary to pre-treat with at least a five micron sediment filter to insure adequate UV treatment.
Sizing suggestion: Use either size with UVSS-6 and UVSS-6M units, but use larger size only (4.5" X 20") with higher flow sizes.
