The Fresh-Aire UV APCO™ is the next generation in Indoor Air Quality improvement technology.
The award-winning APCO UV Air Purifier system (Advanced Photocatalytic Oxidation) represents a technological advanced type of air purifier.
The APCO UV uses a unique combination of UVC light and activated carbon to achieve germicidal and odor reduction without producing any harmful ozone. Ultraviolet (UVC) light reacts with titanium dioxide infused into the carbon which effectively disintegrates the captured contaminants and leaves only harmless water vapor and CO? to be released back into the air.
For over a century scientists have known about the germicidal properties of Ultraviolet light. We love our furry friends, but nobody wants home guests to smell the kitty box or last night’s fish dinner lingering around.
APCO UV removes odors by transforming odor-causing VOC molecules into harmless water vapor and CO2. The UVC light in APCO works just as well at keeping AC coils clean as our non-PCO products. Volatile Organic Compounds (VOCs) can make indoor air smell bad and can be harmful to your health. There are two common UVC emitting lamps types currently employed for pond or aquarium UV Sterilization: the low pressure and the medium pressure mercury lamp. The emission peak of the Mercury electron transition within these low pressure (hot cathode) UV lamps is fixed in both energy and wavelength. The low pressure lamp used by most all Premium Aquarium & Pond UV Sterilizers (not always the low end UVs such as Jebo & AquaTop) is clearly the better choice based on this information.
The low pressure lamp does have one flaw which the medium pressure lamp does not suffer from and that is the low pressure lamp is affected by water (or air) temperatures and operates best between 20 C (68 F) and 40 C (104 F). Many UV Sterilizers come with quartz sleeves which form an air pocket between the lamps and water that in theory increases operating temperatures. HOWEVER my own tests have shown this improvement to be nominal at best especially when compared to a well designed direct contact UV Sterilizer.
In a test with a custom 15 Watt UV Sterilizer and a 13 Watt Quartz sleeve UV Sterilizer (a well designed one at that), the increase in temperate was only 2 degrees F (I have observed up to 5 degrees depending on the units compared). This test started at 68 F and was conducted over 15 minutes, then water was removed from the units and the temperature measured.
I have serious doubts to these claims based on the fact the emission peak of the Mercury electron transition is fixed in both energy and wavelength and I don't think coatings can emit additional UV to any advantage. One such company, Emperor Aquatics, makes the claim that their UV Lamps feature an internal chemical coating that provides added resistance to solarization.
The Hot Cathode lamp operates from a ballast or transformer and requires a device such as the glow switch starter to preheat the electrodes in order to start the lamp. Operation at low temperatures may result in excessive lamp blackening and rapid depreciation in ultraviolet 'C' output.
Comments attacking the authors rather than the subject matter with “straw man”, ad hominem statements will be immediately marked as spam so that future posts by such individuals here or elsewhere in the blogosphere will be recognized as such. This UV Sterilizer is without equal at any price for those desiring the BEST UV unit for their pond or large aquarium system.

The Royal Sovereign RCD-2000 4-way Counterfeit Detector provides multiple levels of counterfeit detection. The UV counterfeit detection system allows for easy verification of security threads on bills and holographic images on IDs.
The magnifying lens conveniently equipped on the top of the unit allows for the verification of microprinting, which are tiny text, numbers, and markings hidden in the bill.
Watermarks are hidden images embedded within the authentic bill's fabric that are difficult to see.
With the introduction of smart phones, tablets and other handy electronics, eyes are exposed to harmful light spectrums now more than ever. That being said, it may occur to some that a pair of sunglasses should suffice for eye protection. You can be proactive about protecting your eyes from harmful blue light and UV rays by wearing BluTech lenses in your favourite frames. It’s important to realize that one of the keys to controlling the risk factors for any disease- including AMD- is efficient patient education. The ceramic metal halide lamp is commonly found in shops, special stores, boutiques, museums, pubs, studios, and others.
Established in 1992, CNLIGHT is an experienced ceramic metal halide lamp manufacturer and supplier in China. Designed in simple, elegant style and in well-matched, fresh and bright colors, the dimmable lamp can create a comfortable, relaxed atmosphere for you. Due to our consistent dedication to product improvement in line with international standards, we have received the ISO9001 certification. As an experienced hid ballast producer and provider, CNLIGHT also provide UV lamp, metal halide lamp, LED lighting, automotive lighting, energy saving lamp, and many other products. The superior bulb reduces odors, allergens and other air contaminants while the lower level bulb next to the coil prevents mold and bacteria from growing within your air handler or furnace.
The APCO UV Purifier unit is installed in the ductwork of your central Air Conditioning & Heating system where it cleans the air as is passes through. APCO UV Air Purifiers are particularly effective at reducing odor-causing and potentially toxic volatile organic compounds (VOCs), including toxic chemical vapors such as toluene & formaldehyde.
Because this frequency of light is filtered out by the Earth’s atmosphere microorganisms have no defense against it.
There are thousands of different VOCs produced and used in our daily lives, including toxic chemicals such as formaldehyde, benzene, and acetone. Generally this is not a major concern considering most aquarists operate their aquariums well within this range. Unfortunately the quartz sleeve is accepted as a standard that sounds great in theory, but in practicality is not a significant improvement in most applications (I would recommend them in some applications such as Lobster tanks, but even here a pre-heater would also be recommended). Coatings usually capture UV and convert the emission wavelength via further energy transitions to some visible part of the spectrum, perhaps with several spectral peaks depending upon the composition of the coating.
The electrodes, located at the ends of the lamp, are tungsten filaments coated with emission material and, under normal operation, govern the life of the lamp. It comes equipped with a magnifying lens to aid in the viewing of microprints, a magnetic sensor that will detect traces of iron in authentic US bills, a fluorescent light for easy viewing of hard to see watermarks, and UV detection which reveals the hidden security thread on bills and hidden holographic images on IDs.
The most notable microprinting security marking is the text printed on the security thread of each US bill.

The RCD-2000's fluorescent plate will shine light through the bill to reveal a watermark image that is located on the far right side of the bill (bill facing up). This guide will help you determine if a US bill is authentic or counterfeit by diagramming the location of the markings present on all genuinely minted US bills. In fact, our eyes are exposed to harmful high energy blue light and UV rays more often than many of us realize. To put it simply, blue light causes gradual oxidation and deterioration of the macula and leaves eyes more susceptible to macular degeneration, contrast sensitivity and issues with glare. BluTech lenses are scientifically proven and are infused with the precise balance of ocular lens pigment and melanin to defend your eyes against harmful blue light spectrums both indoors and out.
By wearing blue-filtering lenses, maintaining a healthy, active lifestyle and supplementing with a triple carotenoid formula, sight stealing conditions like macular degeneration can be avoided and vision can be preserved into old age. Optimized electric arc design and spot size helps guarantee precise control of light distribution.
The ceramic metal halide lamp provides compact structure, optimized design and maximum lumen output. In order to better serve our customers, we also provide other products such as light fixture, lamp, automotive lighting etc., in addition to ceramic metal halide lamp. With ponds, this is still not a major concern in that most problems, including algae occur in warmer months.
The Hot Cathode Germicidal UV Lamps are similar in their operation to the standard fluorescent lamps. In view of the fact that the life of the electrodes is shortened by frequent starts, the lamp life is rated according to the number of times the lamp is started. Ultra violet light, such as that found in a UV light air purifier, can kill toxic substances in your home, greatly reducing allergens, killing germs and enhancing your family’s health. When viewed under ultraviolet rays, the thread will glow a certain color depending on the bill denomination. Thus, it’s particularly imperative that those who work or play in the sun, construction workers, office workers, farmers, truck drivers, athletes and beach goers (to name a few) protect their eyes appropriately against this hazardous light. Further, such lenses effectively soothe tired, strained eyes and ward off computer vision syndrome for those who use computers frequently. L'ajout d'une led ambre permet d'augmenter la palette des jaunes et des blancs chauds, les leds RGBW utilisent une led blanc froid car le mélange RGB ne donne pas toujours un blanc neutre.
Most government issues IDs, such as drivers licenses, will have an invisible holographic image printed on the ID that will only be revealed under UV light. The RCD-2000's magnetic detection will beep and blink red if it detects this magnetic trait in the ink. Objects and text will also appear clearer, sharper and better defined as a result of wearing blue-filtering lenses. Fluorescent, CFL and LED bulbs all have a high blue spectral emission; and if you’re reading this via your smart phone or computer, you’re more than likely being affected by the blue light coming from your LCD screen.
And while for years doctors prescribed UV blocking lenses as a method to guard against this harmful light, it is now possible to get prescription lenses that have wavelength selective light filtration (or, the ability to filter blue light specifically). Investing in a pair of quality blue-filtering eye glasses and sunglasses for year round use is one of the best things you can do for your eyes.
