Q: I already have a duct mounted UV air purifier, will these do more
for me if I add it to what I have?
A: Even better! If you have one by a competitor you can trade it
in and take up to 50% off, depending on the unit you have, no matter how old
it is, for one of our air duct UV air purifiers! Just email us with what you
have!
Q: I saw a similar item, called an ozone generator. Is this the
same thing?
A: The CaluTech products are not ozone generating air cleaners.
Ozone is harmful to your health. See our “ultraviolet" More Information page
to find out more about what an ozone system really does.
Q: Do your UV lamps produce ozone?
A: Many UV lamps intentionally produce ozone in big amounts
(UV-V), which we do not recommend, nor does the EPA or American Lung
Association. The UV lamps we use (UV-C) have special tubing that filters
out the 185nm ozone wavelength, however all UV lamps that are considered
'ozone free' do produce some ozone, but the amount of ozone produced is so
minute (0.002ppm) it is not considered an ozone producing lamp.
Q: How does your product compare to the ionic purifier on TV?
A: Simply put, to date there is no known scientific evidence that
ionic air purifiers actually help people in any way, just opinions, no proof.
UV-C is proven. That's a good marketing department they have!
Q: How long are UV lamps good for?
A: CaluTech products use UV-C germicidal lamps which operate at a
wavelength of 253.7 nanometers and can last as long as 3 years. Each lamp is
under warranty for 1 year, and 36W replacements are only $22.99 each, not $40
or $80 each like other companies (we don't mark them up). Replacement 18W
lamps are $22.49. It is a very cost effective UV air purifier. The lamps are
known to operate for as long as 3 years. We recommend annual changes of the UV
lamps for maximum ultraviolet air sterilization.
Q: Why are your UV-C germicidal lamps / bulbs so inexpensive?
A: It's very common for customers to think our UV lamps are not
efficient like competitors because they are under $25, but the fact is they
are more powerful than most UV-C germicidal lamp products used in other UV air
purifier systems. Plain and simple, we don't mark them up. You can find our
same style lamp used in our UV air purifier at a competitor site for $45 each,
and we even found another for $107 each, that's just ridiculous. Lamp cross

Q: How much maintenance does the unit require?
A: CaluTech
Blue™ air purifiers require 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. Portable units use a washable filter.
Replacements are only $10 to $20 if needed, that's it!
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. If you do not
wish to install a furnace duct mounted germicidal air purifier you should have
a qualified contractor install it for you. Installation if very simple and
only requires a drill with a 2" holesaw and a phillips screwdriver, that's it!
(holesaw can be 1 3/4, 1 7/8, 2, 2 1/4, or 2 1/2)
Q: What kind of warranty does CaluTech offer?
A: The CaluTech
Blue™ , CaluTech
Mini-Blue UV air purifiers carry a warranty of 10 years against parts and
labor. The Airtronics UV purifier carries a 5 year warranty, and the Hurricane
portable UV air purifier carries a 90 day warranty. We also offer replacement
parts here
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. The Blueray produces
a whopping 40,000! No other unit we're aware of on the market can
compete. 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. Some references you can check:Ultraviolet and Infrared engineering by
Summer, Interscience Publishers 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 to US Canadian standards, encased in a steel box and OSHA
compliant for commercial applications. All CaluTech inner components use only
UL / CSA certified parts.
Q: How many watts? What are the details of the bulb?
A: UV-C: 24-26 Watts. Bulb: 36 watts each hot cathode. This is
the spec for the Blue, Hurricane, and Airtronics UV air purifiers. The high
output duct mounted UV air purifier features 120 watts. The CaluTech
Mini-Blue furnace / A/C duct mount air purifier features 2 18w lamps with
short lamps for tight areas.
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: What is Snapcat?
A: Snapcat™ is
an advanced air oxidation technology, commonly called Photocatalytic
Oxidation. A Photocatalyst for air purification. To read more about

Q: How much does all this cost?
A: Units on the market are similar in price, but usually much
higher. The CaluTech Blue is fully guaranteed.
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: 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: It is for ventilation only but you can benefit from the
CaluTech Hurricane, a portable system that we created for people who do not
have forced air ventilation. The United Nations uses this same air
purifier.
Q: I've just received my furnace air duct UV air purifier. The
instructions explain everything well, but I'm still not sure where to put it?
A: If you have A/C we recommend installation above the coils. If
you do not know where they are look for a drain hose or copper lines entering
your air duct. This is where the coil is. You want to install the unit above
this coil. Because coils are always wet, even when the A/C is not running, it
becomes a breeding ground for bacteria, viruses, dust mites, and mold. The UV
light shining down on this coil burns all of these pathogens up. DO NOT drill
right into the duct where the drain or copper lines are coming out. You must
install it above the coil. If you run a drill bit into this coil all the freon
will come out and you will need an HVAC contractor to open the duct and repair
the coil, or even replace it. A good idea is to drill a small inspection hole
above where the coil is, or even open the air duct to look at where it sits,
so you know you've installed it in the right spot. If you do not have A/C you
can install the unit easily in the cold air return line, which is the duct
that brings the air in the home or building to the furnace so it can be
heated. If you're in doubt, call a heating & air conditioning company to
install it for you. It doesn't cost much to have it professionally installed.
Install time is usually less than 15 minutes. Maximum plenum temp is rated at
140F.
Q: I have a humidifier on my supply duct. Can I install the UV
air purifier near the humidifier?
A: Yes, at or above the humidifier. If you install it below the
humidifier water droplets can drip down on the lamps and shorten their life.
Q: My HVAC contractor cut the cord off the CaluTech duct mounted
air purifier and wired it direct to the fan. Does this mean I have no warranty
now?
A: You would have been better off with the unit on always, not
connected to a relay or switch on the fan. When the fan isn't running the
pathogens and mold spores in the air don't stop too. In addition, the dust
mites don't stop mating and multiplying. You want the UV on whenever possible.
If mounted at the coils keep in mind that they are always wet, even when the
fan shuts off. If the UV goes off at the coil for even 10 minutes mold already
begins to form. Keep it on for cleaner air. This extends the lamp life and the
electrical cost is no more than a single light bulb.
Q: Will you really beat any price by $20 ?
A: Yes, if the competitor's unit is comparable, no matter what
the cost is, we will beat it by $20 if their price is lower than ours,
guaranteed. Comparable means the unit has the same amount of UV sterilization.
For example, if you find a 2 lamp air purifier like the CaluTech for a low
price and it performs with the same amount of UV generated we will offer you
ours for $20 less, even if it's on sale.
Q: If the air duct UV air purifiers fail how do I get my
replacement?
A: That's easy. No return authorization needed, just send it back
to us and we'll send you the replacementimmediately. Be sure to include the
name and zip code inside the box that you used when you purchased so we can
locate your information (unless your unit has a warranty serial number tag on
it. If it does we scan the bar code and know who you are).
Q: What exactly is ultraviolet light?
A: Ultraviolet light is an invisible light (to humans) but many
insects can see it (known as phototactic eye sight). UV light emits at
different levels called nanometers (a unit of measurement that is one
billionth of a meter). Ultraviolet light is separated into three common
spectrums. UVA operates between 315 and 400 nanometers (nm). These are known
as black lights and many insect zappers use this UV lamp to attract insects to
the zapper because the insects think the light they see is the sun. UVB is
used for tanning beds and operates between 280 and 315 nm. UVC is used for
UVGI (ultraviolet germicidal irradiation) and this is what our units operate
at. This light has a wavelength of 100 to 280 nm. Our products operate at
253.7 nm which is the optimal level of UVC light for sterilization of the air,
and even water. UV light is present in a fluorescent lamp tube which contains
a mixture of 3 mgs of mercury and a phosphor coating. When UV lamps are
energized the electrical current is mixed through the lamp tube that contains
the phosphor and mercury vapor. The atoms in the Mercury absorb the energy
from the electrical current which causes the atoms to become unstable. The
atoms seek to become stable again so in order to do this they must lose any
extra energy they contain. When the atoms release this energy it is released
in the form of ultraviolet radiation. When the UV radiation is present in the
tube lamps it attempts to get out of the phosphor coated lamps (coated inside
the tubes). When this happens UV light is released. The more or less amount of
phosphor coating inside the lamp tubes the higher or lower the amount of
nanometers. With different mixes of phosphor the desired amount of UV is
produced (A, B, or C).Our UVC light penetrates the outer membrane of viruses,
bacteria, mold, and even yeasts. When this happens the DNA of the microbes is
modified, which causes modifications to the DNA structure, and eliminates the
possibility of these microbes to reproduce, so they eventually all die off
just as humans would if we could no longer produce. All microorganisms have
different levels of tolerance to radiation and these levels are measured
(known as a D Value) which makes it possible to estimate the time of exposure
required to destroy these different microorganisms. The chart on our home page
shows many of these values and where possible we also link to more information
about the virus, mold, bacteria, yeast, etc.
Q: How hard is instalation?
A: Take a look for yourself.
