Germ Guardian Ac4010 Table Top Muti-layer Air Purifier Review

Average Reviews:

(More customer reviews)Hello everyone. I just received this tabletop air filter and sanitizer today in the mail from Amazon. Initial impressions are these:
1) Great size, will fit any table-top, even night stands.
2) Solid Build quality in the molded plastic housing and electrical cord.
3) SUPER QUIET blower fan with or without filter installed.
4) *Perfect* Air Flow Rate. **Too fast of an air flow rate and there is no way the Germicidal action will occur as it takes time for the DNA Base Pairing of Germs to be disrupted, which is the core of Germicidal UV Technology.
5) Incorrect labeling of the UVC Germicidal lamp (it says UVA, but is CLEARLY UVB at worst**).
6) A common problem with an easy fix... "My bulb isn't turning on!!!" SEE BELOW;
UV Basics; Mercury Vapor Tube lights produce 4 distinct peak UV outputs of light:
Near-UV - "Black Light" - Causes Fluorescence - Peak output at Mercury's H-Line @ 404nm. 400nm+
UVA - "Black Light" - Causes Fluorescence - Peak Output at Mercury's I-Line @ 365nm. 315nm to 400nm.
UVB - "Invisible" - Causes Fluorescence in only special materials not used for "Black Light". 280nm to 315nm.
UVC - "Invisible" - Causes no Fluorescence - Germicidal - Peak output @ Mercury's Line @ 253nm. 100nm to 280nm.
Vacuum UV - "Invisible" - Absorbed by Air and Glass - Requires Quartz Envelope - Creates Ozone - Peak Output at Mercury's Line @ 184nm. 100 to 200nm.
This unit produces no ozone. So from that we know that the bulb used inside is a UVC bulb not in a Quartz Envelope. It should appear lit up as a sky-blue color to the naked eye (you have to depress the safety switch to the top left of the bulb for it to turn on) and will not cause much fluorescence at all compared to a "Black Light" bulb. It is a Coated Glass UVC Low Pressure Mercury Vapor 6 inch Lamp rated around 4Watts. These bulbs last an exceptionally long time and rarely burn out. This Unit get a lot of bad reviews for the bulb being irreplaceable and often not working...
Common problem: "My Bulb won't TURN ON/LIGHT UP!!!";
When I received my unit, my bulb did not turn on. However after a few minutes of being on I noticed a very very faint glow on the left corner of the bulb. These kinds of bulbs are low-pressure mercury lamps and they run on high voltage. High voltage causes faint glowing even if only one side of the bulb is connected because some of the current still affects the mercury gas inside. These kinds of bulbs VERY VERY RARELY Burn out unless physically broken/destroyed. They do not even burn out from prolonged use, they just get dimmer as time goes on. So; there is a faint glow, thus the bulb is not bad. This leaves an electrical connection problem. Clearly high voltage was present from the faint glow - the circuitry must be OK. This leaves mechanical connection problems; let's open 'er up and see what's wrong...
1) The bulbs is held in with a plastic cap on each side held in place with two small philips screws. They are easily removed, but be sure the unit is OFF AND UNPLUGGED. Be sure not to damage the fragile bulb. Just remove the plastic caps and screws. You'll see there is nothing holding the wires of the bulb in, they just sit on tiny metal trays. Here is where the electrical problem is - a weak connection!!!!
2) Carefully remove the bulb with clean dry hands, and very very gently bend the wires a very slight amount so that they are held against the metal trays when the bulb is placed back in. You want the silvered tips of the wires to sit flat on the trays making good contact. Hold bulb firmly but gently in place in a position where it makes good contact to the trays and replace the plastic covers. Carefully put the screws back in and be sure the bulb does not shift position. Do NOT over tighten.
3) Plug unit back in, depress the safety switch with a non-metal/non-conductive object, and turn the unit on. The bulb should now light up fully.

[...]I recommend this unit to anyone who understands how to unplug it and use a philips screw driver since it seems the majority of the time the bulb shifts loose during shipment.
