REKO LightingR2000 Air Purifier Whole House Uv uvc Light in Duct for Hvac Ac (Air Conditioning) Duct Germicidal Filter

INSTALLED: July 17, 2020 UPDATED: July 16, 2021 - Finally found one bulb out! You will need to get new bulbs with the G23 base and rated at 9 watts. Some bulbs mention the glass also filters out the ozone causing frequency radiation. I continue to be 100% satisfied with this unit after one year.Original Post: Our HVAC system is from the 90s. One of the characteristics we noticed was how the air did have a 'wet basement wall' smell almost a moldy smell. Beginning each season we often would run the AC with the windows open for a day to get things breathed out. This I found out to be referred to as 'dirty sock syndrome'. Good name. My first research about the topic found what others were doing to help reduce or eliminate the problem. Here is a list of different methods and results, you will often need to gain access to the evaporator coil:1 - I could visually see some telltale mildew/mold sitting on the fins of the coil. I first used a coil cleaner like NuCalgon rinse-free cleaner. This is a chemical cleaner that does help clear the fins of dirt and mold. NuCalgon even makes one that is germicidal. RESULT: This does help the issue as it physically and chemically goes after the mold but after a while (about 1 week) the problem slowly returns.2 - Purchased a handheld steam gun that directs a blast of hot scalding steam to the coil fins. Here I treated all of the coil area with steam to kill the mold with heat. (general sterilization temp is 160F and a duration time. Steam is 200F). RESULT: This does greatly help the issue as it 'cooks' the mold but after a while (about 1 week) the problem slowly returns.3 - Spray a disinfectant, hydrogen peroxide, onto the coils. RESULT: This does a good job to knock out the problem but after 1 week the problem slowly returns.4 - Bi-Polar Ionizer. Here is installed a NuCalgon iWave-R ionizer that is designed to be installed right after the airstream from the furnace filter. This device did indeed work well and I use it based on need (smoky cooking odors). This device is intended to charge the air with ions and keep the coils from developing mold. It also continues to clean the air of the home. These units are pricey (around $500) and it does a good job, but I still could tell that the dirty sock problem was slightly there (reasonable level).I installed my REKO UV system on July 16, 2020 and here are some of my remarks:- Unit is rather basic in operation. There is a ballast in the base unit, no OFF/ON switch as the intention is that this unit runs 24/7 and uses UV-C light to kill mold/mildew. You could practically make one yourself with the correct knowledge and parts. But it's important to keep this unit on always.- Installation is also straight forward. Just two hole openings to accommodate the lights.- After installation I debated whether to do a steam and hydrogen peroxide cleanse as I knew that would keep things happy for at least a week. But I was curious to see how the lights could change the situation on their own.-After about 48 hours, there was a noticed reduction in dirty sock syndrome (D.S.S.).-After approx. 100 hours an even better clear up of the D.S.S.-At the time of this writing, approx. 400 hours the air has been kept pleasant and I can only slightly detect D.S.S. when I put my face right into a air vent and inhale.I see from reviews that people have been using these units to make a sterilization chamber for objects. This is a smart technique and I can see how it would be effectual (COVID-19 disinfection).Some people try to use the unit to sterilize the air as it passes (air sterilization not surface). I am not so convinced that this will work as the short span of time the air passes air the light is short. The only way to improve results would be to slow the rate of air flow or increase the intensity of the light (physics at play).I do like to occasionally use the Bi-Polar Ionizer to boost the effectiveness and perhaps that is something you may wish to look into.Best of luck to you in your decision about achieving better air quality for yourself and others!Stay happy, stay healthy!Christopher B.

I used a hole saw attached to a drill in conjunction with the template (included in the package) to create the two holes that the lamps fit through. I installed it above my filters and blower for maximum UV exposure/effect. I also installed in conjunction with the appropriate MERV rated filters for my furnace. The indoor air quality of my home has vastly improved. I no longer wake up with sore eyes, sore throat, or stuffy nose. I bought an older home (1966) and I was dealing with mildew spores and air quality issues.

I feel much better and notice e the improvement in our HVAC air quality

This product is a LIFESAVER!! Genuinely thought I was gonna have to move out of my home do to our basement flooding and getting moldy and our furnace trapping the spores. I’m SEVERELY allergic to mold spores and was getting so sick from it. I decided to take a chance and by this little death ray. After a few hours, the musty smell GONE. I was shocked!! Did not expect it to be gone that fast. Super easy to put in and fool proof. Definitely worth the money if you suffer from allergies or want cleaner air!

all good
