The only residential UV system available that is capable of destroying harmful micro-organisms in pool water to the level claimed.

Purity UVC Vessel

Our scientists, engineers and consultants analyzed the leading UV Pool systems and found that they had significant flaws and did not perform as they claimed.

CHOOSE PURITY UVC FOR THE SAFEST AND BEST SWIM

DELIVERS 25% MORE UV-C DOSAGE INTENSITY OR FLUENCE THAN THE LEADING COMPETITIORS

Fluence is the light intensity at a given wavelength and exposure time. Intensity at any given point is determined by bulb strength, the placement of the lamps and the design of the reactor. The exposure or residence time is governed by the geometry and the hydrodynamics (the flow rate and pattern of the water) throughout the reactor.

THE LEADING COMPETITORS LEAVE 100 TIMES MORE HARMFUL PATHOGENS THAN PURITY UVC

Leading competitors have at best a Log 3 reduction. For example, in laboratory tests, starting with 100,000 pathogens, a Log 3 kill leaves 1,000 harmful micro-organisms active after a 99.9% reduction. In contrast, PURITY UVC’s Log 5 reduction reduces the harmful colony to 10 bacteria after a 99.999% reduction. So, the competitors’ UV light manages to get a Log 3 kill rate at best and leaves 100 times more harmful micro-organisms to breed and infect than does the PURITY UVC which gets a Log 5 kill. The competitors UVC systems leave 100 times more harmful viable micro-organisms in the water than the Purity UVC system.



CDC LISTING OF TOP POOL ILLNESSES



According to the CDC, The most commonly reported recreational water illnesses are the following:

• Acute gastrointestinal illness (such as diarrhea or vomiting)

• Skin illnesses (such as rash)

• Acute respiratory illness (such as cough or congestion)

Ultraviolet light instantly inactivates scores of pathogens and harmful microorganisms, even tough to get Chlorine resistant strains, including Cryptosporidium.

Cryptosporidium

Legionella

Pseudomonas

Coronovirus

Shigella

E.coli

Chloramine

Giardia



PURITY UVC’S SUPERIOR DESIGN FOR 99.999% PURITY

OPTIMAL VESSEL DESIGN

Purity UVC’s 4″ vessels are half the diameter of other vessels, and we separate our lamps, so all the water flows right by the UV lamps, and pathogens cannot survive.

REFLECTIVE TECHNOLOGY

Purity UVC’s stainless steel reflects UV rays back to the center. This, along with lamp spacing, eliminates shadowing so pathogens cannot survive.




OTHER UV SYSTEMS ARE FLAWED: 
NON-REFLECTIVE, OVERSIZED VESSELS WITH CLUSTERED LAMPS

PROBLEM: DIAMETER

The diameters of other UV pool systems are too big. UV intensity decreases 12% or more per inch, resulting in weak UV rays at the edge of the vessel, allowing pathogens to survive.

PROBLEM: SHADOWING

Other UV pool systems use plastic vessels and cluster their lamps in the center, allowing shadows that enable pathogens to survive.



OTHER UV SYSTEMS ARE FLAWED:
TURBULENT WATER FLOW

TURBULENT WATER FLOW

Other UV pool systems have oversized vessels with undersized inlets/outlets. This creates turbulent water, allowing pathogens in the fast currents to survive.

THE PURITY UVC SOLUTION

Purity UVC’s narrow vessels with wide inlets/outlets, create even flow without turbulence, so pathogens cannot survive.



LOWEST COST OF POOL OWNERSHIP

Reduce Chemical Use by 90%.  Save Hundreds of Dollars each Season.

Chemicals Only With Purity UVC $avings
Residual Chlorine 3-4 ppm 0.3-0.5 ppm 90-94%
Chlorine Shock Every 1-2 Weeks Every 3 months 85-93%
Algaecide 1-2 times a year Never 100%


Limited Lifetime Warranty
Only Purity UVC offers a lifetime warranty on its stainless steel vessels. Competitors can’t match Purity UVC because their vessels are made from plastic that eventually cracks and leaks.
Purity UVC offers and industry best 3-year warranty on the electrical control box

WHY CHOOSE ULTRAVIOLET?

UVC light neutralizes harmful organisms by damaging DNA. UVC also breaks down chlorine by-products and chloramines that commonly lead to eye and skin irritations, asthma and allergies. UVC is chemical-free and has no negative side-effects or by-products.
