FREQUENTLY ASKED QUESTIONS - Ultraviolet
Q: I saw a similar item, called an ozone generator. Is this the same thing?
A: Absolutely not! The CaluTech Blue™ is not an ozone generating air cleaner. Ozone is harmful to your health.
Q: What's included?
A: You are supplied with the new CaluTech Blue™ air purifier system, two (2) high intensity ultra violet lamps, a 'stick on' template to place on your home or office ventilation duct for ease of installation, drill bits, screws, a 10 year warranty, instruction sheet, and 6 screws for mounting the unit.. Spare lamps may also be purchased, but you will not need a spare bulb for 12 months.
Q: How much maintenance does the unit require?
A: The CaluTech Blue™ requires minimal maintenance. All you need to do is change the lamps once a year for maximum efficiency. Once your unit is installed, you simply plug it in.
Q: Is this something the average homeowner can install themselves?
A: Yes. Installation is simple, but if you prefer you can contact your local heating and air conditioning company for installation or a handyman. The unit can be installed in as little as 20 minutes.
Q: What kind of warranty or money back guarantee does CaluTech offer?
A: The CaluTech Blue™ system carries a warranty of 10 years against parts and labor.
Q: I've seen other units available that claim to be high powered air purification utilizing UV. How does CaluTech's unit compare?
A: There is no comparison. The Calutech Blue™ produces over 24,000 microwatts of complete air sterilization and has been tested to safely sanitize between 98 and 99.9 percent of the indoor air. No other unit we're aware of on the market has this rating. The effect of irradiation is based on microwatts and time of exposure. The lethal exposure period of an organism is determined by its susceptibility. The wavelength of radiation, the density of the radiation flux (watts per unit area) and time exposure. These UV lamps are regulated at 253.7 nm energy. The germicidal effectiveness is proportional to the product of intensity time from one micro-second to a few hours. CaluTech estimated a typical air velocity of a home furnace and doubled the amount of UV actually needed .

American conference of Governmental and industrial hygienist, Threshold limits for workroom air.
Ultra-Violet Radiation by Koller, Pub. John Wiley and sons.
Any state government agency should also have information on the technology used in the wastewater field which is much more critical than air sterilization. UV is commonly used in place of chlorine for disinfections and the technology has been used extensively in the pharmaceutical industry.
Q: There are a lot of units on the market. Where does the CaluTech Blue™ fall into place?
A: Because of the recent scare of bio-terrorism, companies have virtually popped up overnight selling units that look a lot like the CaluTech Blue™ purification system. These are NOT CaluTech units and they do not perform to the level of CaluTech standards.
Q: Is the CaluTech Blue™ constructed in a solid manner, and are the electrical components safe?
A: The Calutech Blue™ is encased in a steel box and the electrical components are UL and CSA Listed.
Q: How many watts? What are the details of the bulb?
A: UV-C: 26 Watts. Bulb: 36 watts, Hot Cathode.
Q: Is Hot Cathode better than Cold Cathode?
A: In the uppermost vertical section of your plenum both hot and cold cathode tubes suffer diminished effectivness based on cooler temperatures. We overcompensate with excessive UV-C wattage to get a maximum kill without ozone.
Q: How much does all this cost?
A: While units on the market are similar in price, but usually much higher, they do not outperform CaluTech. The CaluTech Blue is fully guaranteed. Pricing can be viewed in the shopping cart. Replacement lamps, are available for an average $26.00 each and should be replaced annually for maximum efficiency.
Q: I've had a CaluTech system in my home for over a year and have never changed the lamps. Does this mean it is no longer cleaning the air?
A: No. Although the lamps should be changed yearly for maximum efficiency, your unit is still cleaning the air. Not changing the lamps every year lowers the effectiveness of the sanitizing cycle.
Q: Similar UV air cleaners sell for $500 or more. Why is the CaluTech Blue sold for such a low price?
A: CaluTech is a wholesaler and manufacturer of air purification equipment. Because we're not a reseller for someone else we don't need to profit more. Many companies sell products by others. This causes pricing to be raised more and more as the product goes from one company to the next, and finally to the end user...you. We manufacture and sell wholesale to the public.
Q: I'd like to benefit from the use of a UV air cleaner, but I do not have forced air ducts in my home. Can I use the CaluTech Blue?
A: Unfortunately you cannot, it is for ventilation only but we are currently testing a portable version of the CaluTech Blue which should be available in early 2004.
