I Tested And Reviewed 10 Best In Duct Uv Air Purifier (2023)

I recently installed this UV light on my HVAC unit to combat the unpleasant wet sock smell in my house. Before considering professional duct cleaning, I tried other remedies such as cleaning the filter and coils, as well as spraying bacteria-killing spray in the ducts. While these temporary solutions helped initially, the smell persisted. However, after installing this UV light, I noticed a significant improvement within four days. I believe that the combination of the previous cleaning efforts and the UV light effectively eliminated any remaining bacteria in the coils, resulting in clean-smelling air. It has now been approximately 90 days since the installation, and the light continues to work effectively. The installation process was straightforward, especially since I could easily access the attic where my unit is located.

The installation of this UV light was a breeze. Although I did encounter a minor setback when I found my sheet metal shears afterwards, the overall process was simple. I was able to wire the light directly to the electronic air cleaner (EAC) terminals on the electronic control module (ECM). Having an HVAC background, I made sure to verify the power specifications before proceeding. The light operates by cycling on only when the fan motor is running, which is a clever feature.

I have been experiencing bouts of vertigo without any apparent cause. After researching possible reasons online, I came across mold as a potential culprit. While my house didn't have a significant mold problem, I decided to install this UV light as a precautionary measure. It is a more affordable alternative to purchasing an air purifier, which also incurs maintenance costs. Since installing this device, my vertigo has gradually diminished. While I can't definitively attribute the improvement to the UV light, it could be a contributing factor.

The installation of this UV light was quick and hassle-free. It required a 2 1/8 metal hole saw, and the entire process took me approximately 10 minutes. The light appears to possess considerable power, and I hope it will maintain its effectiveness in the long run.

I opted to have two of these UV lights installed, one on the supply and one downstream of the evaporator. These units have proven to be highly reliable, and the dual LED bulb indicator is a nice touch. I had previously replaced a different model after it failed within a year, but these UV lights have been working exceptionally well.

I recently purchased a UV light for the purpose of destroying odor, mold, and germs, and I must say, I am impressed with its effectiveness. To ensure optimal performance, I constructed a small box out of wood and lined the interior with aluminum to create a reflective surface. I also installed a small fan at the exit point and added a diffuser at the entrance to promote proper airflow. The UV assembly is mounted on the top center of the box.

Upon turning on the unit near a smelly area and allowing it to run for an hour, I noticed a significant improvement in the air quality. The air felt fresher and cleaner than before, which amazed me considering it was just a prototype. Encouraged by these results, I plan to build a larger version of this device and incorporate an air filter. My goal is to create a portable unit that can effectively clean the air in various areas of my house.

It is important to note that while UV-C lights are a great tool for air purification, precautions must be taken to limit exposure to humans and pets. UV-C light can be harmful, so it's crucial to use this product responsibly.

I highly recommend this UV light for individuals suffering from allergies. It has the potential to significantly improve indoor air quality and provide relief from allergy symptoms. I am currently working on a larger version of this box, and I will be sharing the details once it is completed. Please keep in mind that this is a prototype, and the construction process is relatively simple.

For my prototype, I used a heavy server box and lined the inside with reflective aluminum foil. To ensure proper air intake, I had to improvise and use an HP monitor box, cutting large circular holes on both the monitor box and server box. Additionally, I created rails using cardboard scraps to accommodate an AC air filter, which filters out large particles. The UV-C light is mounted in the center of the box on the side.

To facilitate proper airflow, I purchased a cheap squirrel cage air blower and mounted it inside the box, opposite the air filter. This blower efficiently sucks air through the entrance with the filter, pushes it through the reflective chamber of the server box, and expels it out the other end. The advantage of this design is that I only needed to cut a small slot for the fan, ensuring minimal disruption to the box's structure.

It is essential to emphasize that my construction design and modifications are not UL-approved. Therefore, it is crucial to have a good understanding of electronics and take necessary precautions when working with electrical components. Safety should always be a top priority to avoid any potential hazards.

I started using this box on June 14, 2021, and it has been running continuously for over a year. To maintain a sealed environment, I utilized 3M adhesive spray and duct tape. By spraying the adhesive on the areas that require sealing, allowing it to dry, and then using duct tape, I achieved a permanent and secure seal.

I recently installed the UV light in my duct at the exit of the air handler, as there was no room near the 'A' coil. The installation process was easy, and the product worked well. However, I did have to extend the air sensor wire due to the thickness of the duct.

Following the instructions, I ran my A/C unit fan for 24 hours, and there was a small odor as mentioned in the instructions, but it was not overwhelming. After just two days, my wife has noticed a significant reduction in her allergies, which is a great relief.

In addition to using it in my home, I also installed the UV light in our church's A/C system to protect our congregation from COVID-19. We are thankful to have this added UV protection in our system, as it helps to keep the virus at bay, reducing the risk of sickness and unpleasant smells.

I purchased two units of the 144pro with air sensor, and I found the installation instructions to be simple and easy to follow. The UV lights appear to be well built and of good quality.

Although my husband has not installed the product yet, we did plug it in to test it, and it seems to be working well. He believes that the installation process will be fairly straightforward. Compared to smaller single lights, this UV light is a significant upgrade and worth the extra money. With multiple bulbs, we have the assurance that if one light were to fail, we would still be covered. I personally love UV lights and am excited to have this installed in our HVAC system.

I have been using UV-C lights in my HVAC systems for 18 years, and I must say that the BioShield UV Duct Lamp is a great value for the money. Unlike some of the more expensive "name-brands" or the ones sold by home AC installers, this lamp is well-constructed and does not break easily. I have had to replace two sets of Honeywell ballast units in the past 18 years, but the bulbs in the BioShield lamp have lasted about a year each.

One of the standout features of this lamp is the indicator light that lets me know if the bulb is working properly. It is a convenient feature that allows me to check from a distance and ensure that the bulbs are still good. Additionally, I appreciate the fact that the bulbs used in this lamp are made of doped quartz, which blocks the wavelength of light needed to produce ozone. This means that the lamp does not generate ozone, unlike some other UV lamps on the market.

I did some testing with an O3 meter before installing the lamp, and the results were impressive. The ozone levels never went above the ambient level of 0.02ppm, even after 10 minutes of testing. However, it is worth noting that using replacement bulbs with a different part number may yield different results, so it is important to pay attention to the type of bulbs you are using.

The installation process was relatively straightforward, although I did encounter a minor issue with the installation template being incorrect, as others have pointed out. However, this did not affect the overall performance of the lamp.

In terms of longevity, I will have to update my review once I have gone through the first bulb change. But based on my initial experience, I am confident that the BioShield UV Duct Lamp will continue to perform well.

I recently purchased this UV light for my AC system and overall, I am quite satisfied with my purchase. The packaging was done well, ensuring that all the necessary components such as the bulb socket and ballast were securely placed. However, I did encounter some difficulties during the installation process, specifically in my case where I had to install it above the coil. There were many tiny capillaries blocking access to the support, and I didn't want to risk damaging them and incurring costly replacements. Despite this, I managed to find a solution by drilling a small hole and covering it with transparent tape to create a makeshift site glass, allowing me to monitor the light.

One mistake I made was not considering the stiffness of the connector to the bulb socket. As a result, when fastened to the side wall, the connector was smashed against the AHU wall. I had to add a spacer to ensure that the bulb was level and functioning properly. It would be beneficial for future buyers if the connector had a right angle for easier installation.

In terms of quality, the product was of good standard. I installed two UV lights above and below my squirrel cage fan, connecting them to the 24v A/C terminal. It has been working well for about a month now, and I am curious to see how long they will continue to function effectively.

Prior to purchasing this UV light, my AC service provider recommended adding one, and they quoted me a staggering $550 for a single bulb of this size. Opting for this product instead was a wise decision, as it appeared to be very similar to what the AC company was offering, and the installation process was incredibly quick, taking only three minutes. In fact, the total cost for this installation was only around 10% of the quoted price. The installation itself was easy, especially for AC wiring. I connected one wire to the drain pump's wire nut, and the other wire to the common terminal. It is important to remember to disconnect the breaker before opening it up. Overall, I am pleased with the outcome, and anyone who sees it would assume it was installed by a professional AC service company.

I am happy with my purchase as it allowed me to replace my old UV setup from the previous owner. The package arrived well and intact, and the low voltage feature meant that I didn't have to cut the power during installation. I simply connected the two wires, taped the light into my AC system in the attic, and it was done. I hope that the bulb will last at least 6-8 months, which is a reasonable timeframe. It gives me peace of mind knowing that our air is now sanitized, and I anticipate that our AC system will have a longer lifespan as a result.

I recently purchased the Haven Plus UV whole house air purifier and I must say, it exceeded my expectations. Not only was the cost significantly lower compared to similar units quoted by HVAC companies, but the installation process was a breeze. With the help of tin snips, I was able to install it in just about 45 minutes, and even faster since I was cleaning my furnace room simultaneously.

The product itself is well-designed and of professional-grade quality. The base mounts securely and the bulb ballast locks in nicely, giving me confidence in its durability. I also noticed metallic pieces inside the bulb, which I believe to be mercury, further reinforcing the effectiveness of this purifier.

While I can't definitively say that it eliminates odors due to various variables, the science behind it checks out, as it is widely used in commercial HVAC systems. I will closely monitor the bulb's longevity and update this review as necessary.

In addition to its performance, I appreciate how the Haven Plus UV purifier provides a clear view of the inside of my AC unit. I discovered white slimy residue on the coil, which was effectively eliminated after just a week of using the purifier. This gives me peace of mind regarding my family's health and the overall cleanliness of our home.

The installation process was straightforward, and I particularly liked that the kit included a circle saw. Although it didn't come with a chuck bit and pilot drill, I was fortunate enough to have a similar kit that had compatible tools. However, if you don't have these tools, you may need to make a trip to a hardware store. The blade provided in the kit cut through the steel AC cabinet effortlessly, and I was impressed by its quality.

I recently installed this UV light unit in my HVAC system and I must say, it has solved my problem perfectly. I needed to change the airflow direction from side to side to front to back, and this unit allowed me to do that without any hassle. The installation process was easy, although the template provided was slightly off, but it was a minor issue that could be easily adjusted.

One thing to note is that you need to have a nearby plug for this unit. The cord is long, but I had to use an extension cord temporarily until I extended an outlet into the closet where my air handler is located. Additionally, I recommend having AC tape ready as the included screws are not very useful when screwing into fiberglass. The template shows an air handler from the side, but mine is below the duct work, so I made sure to position the bulbs side by side to ensure that the air passes through the middle of the lights.

The only drawback of this unit, as others have mentioned, is that you cannot tell when the bulb is burned out. To overcome this, I have set a reminder on my calendar to change the bulb every 12 months. However, I must say that my other UV light has significantly reduced odors in my house and has helped with my son's allergies, so I have high hopes for this unit.

I decided to try this UV light unit after finding mold in my house recently. As someone who works in Engineering at a modern hospital that uses similar UV light banks in their air handler units, I believe that it will work effectively in a home HVAC unit. I took some images with a WiFi Endoscope on my phone and everything looks good so far. I'm looking forward to cleaner air and will update if any issues arise.

I recently installed this UV light system in my HVAC unit and I must say, it has been a great addition. The installation process was fairly straightforward, although I did need to purchase some additional screws to fit my specific ductwork. One notable feature of this system is that it glows, allowing me to easily identify any leaks in my ductwork. This has been helpful in ensuring that my ducts are properly sealed.

One thing to note is that the UV bulb runs constantly, so it's a good idea to have an extra bulb on hand in case it needs to be replaced. I would recommend checking the bulb at the beginning of each heating or cooling season to ensure it is functioning properly.

I decided to install this UV light system because my wife has a sensitive nose and was noticing an unpleasant odor coming from the vents. We had called an AC company, who informed us that our AC was too old for a deep clean and recommended adding a UV bulb to our system or replacing the AC altogether. Opting for the UV bulb seemed like a more affordable option, so I purchased this product.

After about a month of using this UV light system, we have noticed a significant reduction in the odor coming from the vents. While it hasn't completely eliminated the smell, we are optimistic that with more time, it will continue to improve. Considering the cost of a service call, we are extremely happy with the results this product has provided.

In addition to improving air quality, I also decided to use this UV light system to create a bedroom air purification system. The installation process was relatively easy for me, but I do have some experience with these types of projects. I ended up installing a dedicated outlet near my HVAC unit in the attic specifically for the UV light. It has only been a few hours since installation, so I cannot definitively say if it has made a difference in the purity of the air. However, I did also change my return filter, which may contribute to any improvements we experience.

Currently, my family and I are dealing with respiratory infections, with my eldest son and I experiencing sinus issues. We have taken medication and used a neti pot to alleviate our symptoms and prevent the spread of illness within our household. It will be interesting to see if the UV light system helps to further improve our respiratory health.

I recently installed this unit in my central HVAC system and I'm very satisfied with the results. It was a hassle-free installation process and I didn't encounter any issues. The unit immediately started removing mold and other airborne particles from the air duct, which is a huge relief.

The only concern I have is the availability of the UV tube when it needs replacing. I hope that the manufacturer ensures easy access to replacement parts to maintain the unit's effectiveness in the long run.

The installation process itself was straightforward, and I was able to complete it using a drill and hole saw. Tin snips could have also been used. I followed the provided instructions and was able to install two units within an hour. If you're unsure about the installation process, there's a helpful video available as well.

Initially, one of the bulbs didn't work, but I contacted the manufacturer and they promptly corrected the issue without any questions. I appreciate their swift response and excellent customer service in resolving the problem.

I purchased this unit specifically to sanitize my CPAP equipment, and so far, it has been working well. I'm happy with its performance in keeping my equipment clean and sanitized.

Unfortunately, the first unit I received was defective and didn't work. However, I reached out to the company via email on a Sunday and received a response on Monday morning. They immediately sent me a new unit, which arrived on Wednesday. I must commend the exceptional customer service provided by this company. Despite the initial setback, their prompt resolution and willingness to rectify the situation have left a positive impression on me. I would highly recommend this company based on their excellent customer service.

I am very impressed with this unit after installing it. Although I have only used it for a short period of time, I am already noticing positive changes in the air quality of my home. I initially purchased this unit to replace an older one that had stopped working, and I am glad I made the switch.

The installation process went smoothly for the most part, despite the tight spacing I had to work with. The unit was placed in a challenging location, but the provided alignment guide was helpful in determining where to mount it and what modifications needed to be made. I was able to reuse an existing hole in the ductwork, which saved time and effort. The unit sealed up well against the air duct, ensuring maximum efficiency.

One feature that I really appreciate is the dual external LEDs that indicate the operational status of the bulbs. They are bright and easy to see, making it convenient to check if everything is working properly. In contrast, my previous unit only had a sight glass, which couldn't provide this information at a glance. Additionally, this unit comes with a replaceable fuse, which adds an extra layer of protection. I didn't have this feature in my old unit, so it's a welcome addition.

The unit's performance has exceeded my expectations. Within a short period of time, I noticed a significant improvement in the indoor air quality. There was a slight odor initially, but it quickly dissipated. I attribute this to the unit effectively eliminating mold and mildew that had accumulated on the air conditioning coil. The combination of the circulation fan and UV light running constantly has helped filter the air and maintain a more pleasant environment in my home.
