Here are some pictures from an inspection that I did in Alexandria, Virginia this year. As you can see, it is pretty obvious when there is mold growing in your air handler.  If you are suspicious about your indoor air quality, just taking off the cover to your furnace can be “enlightening”. How To Install a UV Lamp On Your Duct? Most UV light sanitizers will come with a paper template for the mounting procedure. It will be installed on your duct where your furnace or air handler is located (here is my detailed guide on installing HVAC UV lights). I recommend following the size and placement of the holes on the mounting template for your UV light system. ultraviolet home air sanitizer You will first need to drill a pilot hole at the install spot, and then you will need to use a saw bit and drill in the hole. The light bulb(s) will go through the hole in the sheet metal duct, and the UV light unit is secured to the ductwork with screws and possibly metal foil tape. Usually, the unit will just be plugged into a regular outlet in your utility room or closet but you also have the option of wiring the unit with your furnace (an electrician may be required for that). How To Pick The Best UV Light For Your HVAC? There are a few considerations to take into account when buying an KNOCK  ultraviolet air sanitizer. There are generally two types of UV light bulbs, the long and short bulb. If the unit you are buying has a longer bulb, it may be more difficult to install if your furnace is in a very small utility closet. However, with a longer bulb, there is more “surface area” so the light may shine along more areas increasing it’s effectiveness. Another factor to consider is the equipment that comes with the purchase. Some UV light systems come with everything you need for the installation including the sheet metal drill bit that you will need to make holes in the ductwork. Almost all UV air sanitizers will come with a few screws to mount the system onto the duct. Another thing to consider is the cord length. Most UV light systems come with a power cord that is 6′ to 8′ in length. If your utility closet doesn’t have a regular 3-pronged outlet, you may need to buy an extension cord that will go to the closest outlet. And again, you can also wire the ultraviolet purifier into the air handler electrical system, and even wire it so it turns on only when the system is on. An electrician or contractor may be required for custom wiring. company website: https://www.k-nock.com/ How Are UV Light Sanitizers Different From Other Air Purifiers? UV lights are different than furnace filters because they kill microbes while they are growing on the surfaces of the ductwork, the A/C coil, the drip pan, and other surfaces. Furnace filters are a very important part of indoor air quality, and I recommend changing them monthly. However, I have seen many air handlers that had very good paper 3M filters, but on the inside there was extensive mold growth. Indoor furnaces and air handling units are perfect breeding grounds for microorganisms like mold and viruses because they are dark, there is moisture, and a prevalent food source in the form of dust. There are “point of use” indoor air purifiers, like the stand alone units you can place in your living room or bedroom. But these units will not affect the air quality of the whole home like how a UV light inside your HVAC can do. Where To Buy The Best UV Light For Your Air Conditioner? The best place to buy a UV light for your air conditioner is in my opinion Amazon. With our web, we have scoured for the best products, and have read the customer reviews. On page, you can be alerted to problems that you may not of even thought of. In addition, the shipping on our page is frequently free and fast.

What is a UV Light Air Purifier? A UV light purifier is basically a light bulb that is designed to emit a specific frequency that research has found to stop microbial growth. It has been known for decades that specific frequencies of light can harm microorganisms. Most research has been done in medical settings to help prevent contagious diseases. The most commonly used UV light frequency is 253.70nm which is the frequency when light passes through mercury vapor. KNOCK Ultraviolet light at this frequency has been clearly shown to destroy viruses, bacteria, and fungi. UV light is typically shining light 24 hours a day inside of your air conditioning ductwork. Most units will have a sight glass that allows you to see if the light bulb is on and still working. You never want to get UV light on your skin or eyes. The ultraviolet bulb will need to be replaced in a year or two depending on the system. UV air sanitizers can have anywhere from one to four UV bulbs --- the most common is one to two bulbs. The lengths of the UV bulbs can also vary. Brand Name: KNOCK

KNOCK uv water sterilizer Disinfecting the surface of objects (1) Irradiation method: It is best to use a portable ultraviolet sterilizer to move the radiation at close range, or to suspend the ultraviolet light. Small items can be irradiated in an ultraviolet disinfection box. (2) Irradiation dose and time: Different types of microorganisms have different sensitivities to ultraviolet rays. When disinfecting with ultraviolet rays, the irradiation dose must be used to reach the irradiation dose required to kill the target microorganisms. When killing general bacterial propagules, the irradiation dose should reach 10000 uW.s / CM2; when killing bacterial spores, it should reach 100000 uW.s / CM2; the resistance of the virus to ultraviolet rays is between the bacterial propagules and buds; Fungal spores are more resistant than bacterial spores, and sometimes need to be irradiated to 600,000 uW.s / CM2; when the target microorganism to be disinfected is unknown, the irradiation dose should not be less than 100,000 uW.s / CM2. Disinfection of indoor air (1) Indirect irradiation method: The high-intensity ultraviolet air sterilizer is preferred, which not only has a reliable disinfection effect, but also can be used when someone is indoors. Generally, disinfection can be achieved after 30 minutes of booting. (2) Direct irradiation method: Under the condition of no one in the room, it can be irradiated by ultraviolet lamp suspension type or mobile type. When using indoor suspended UV disinfection, the number of UV disinfection lamps (30W UV lamp, intensity> 70 uW / cm2 at 1.0 meter) installed indoors is an average of not less than 1.5W per cubic meter and irradiation time of not less than 30min.

Why use portable UVC led sterilizer? Ultraviolet rays are a scientifically proven and reliable technology that can kill bacteria and viruses at the molecular level by killing them. Hospitals often use ultraviolet light to purify surgical equipment and operating rooms. Mini sterilizers use the same ultraviolet light to safely and quickly neutralize bacteria and viruses from the surface of commonly used small baby products, and have been tested by independent laboratories to ensure results. Use conditions and methods of portable ultraviolet sterilizer: Ultraviolet rays can kill a variety of microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsiae and mycoplasma. Any surface contaminated with the above microorganisms, water and air can be disinfected with ultraviolet light. Ultraviolet radiation has low energy and weak penetration, and can only kill directly irradiated microorganisms. Therefore, the disinfection site must be fully exposed to ultraviolet rays during disinfection. Brand Name: KNOCK When disinfecting rough surfaces such as paper and fabrics with ultraviolet light, the exposure time should be properly extended, and both sides should be exposed. The most suitable temperature range for UV disinfection is 20-40 ° C. If the temperature is too high or too low, it will affect the disinfection effect. The disinfection time can be extended appropriately. When used for air disinfection, the relative humidity of the disinfection environment is preferably less than 80%, otherwise it should be Properly extend the exposure time. When ultraviolet rays are used to kill microorganisms protected by organic matter, the irradiation dose should be increased. Air and water suspended particles can also affect the disinfection effect.

Studies have shown that ultraviolet radiation mainly kills microorganisms by radiating damage to microorganisms (bacteria, viruses, spores and other pathogens) and destroying the function of nucleic acids, thereby achieving the purpose of disinfection. The action of ultraviolet rays on nucleic acids can lead to the breaking of bonds and chains, cross-strand cross-linking and the formation of photochemical products, etc., thereby changing the biological activity of DNA and preventing the microorganisms from replicating themselves. This ultraviolet damage is also a lethal damage. The principle of killing virus by portable ultraviolet sterilizer The ultraviolet light used for disinfection is C-wave ultraviolet light. Ultraviolet sterilization and disinfection is the use of ultraviolet light of appropriate wavelength to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and / or Regenerative cell death, to achieve the effect of sterilization and disinfection. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics, and uses specially designed high-efficiency, high-strength and long-life UVC band ultraviolet light to irradiate flowing water to expose various bacteria, viruses, parasites, algae and Other pathogens are killed directly.
