OdorStop OS144PRO UV Air Purifier 144W System with Energy Saving Airflow Sensor

Have 3 AC units and added 1 of the 4 light systems to each of my units. AC company wanted $1500 per system to install single light UV Air Quality unit. Saved myself $3450 by purchasing and installing these units myself. 2 of my AC units had duct board plenums on the supply side and did have to pay AC company $450 per unit to replace with elongated sheet metal plenums. Used a 2.5" multi-purpose Heavy Duty Bi-Hole Saw bit from Home Depot for the UV light holes and simple tin snips to cut the tabs between the holes. Used box cutter knife and scissors to cut through the insulation in the plenum boxes. Had to pre-drill all the surface mounts to work with provided sheet metal screws (not self-tapping). Used a 3/32 inch bit for the pre-drill holes. Would dry fit the system to insure all fits before installing UV lamps and mounting it. Works flawlessly so far. Turns on when air is flow and off when not to extend lamp life. Very pleased with how easy this was.

The installation of the unit was easy, but you will have to have an outlet within 8 feet of the unit. And extension cord is not recommended. This required installation of two duplex outlets for each of my Oder Stop UVC‘s units. That takes time, knowledge and experience.Once installed, both units worked fine. One of the units still works but the other unit has burned out two sets of bulbs (lamps). The issue is the base unit which is the second of two. Oder stop Customer service wants me to return the base unit for repair. To do so, would leave a large hole in the plenum of that system until replaced. They know what the problem is. However, despite several calls, they would not send a new base unit with a box and RMA label to return the defective unit. The lamp is the expensive part for the unit. Since I ordered it from Amazon, odor stop acts like it is not responsible.If you order this product, use Amazon and a protection plan. Otherwise you will be without recourse.

First off, before I even bought this unit, I called OS and talked to Jessica as I was a bit apprehensive about spending this much for a unit, but it was still cheaper than the OEM version (2-lamps) from Carrier. She was able to assure me that the Pro version with the airflow sensor would work fine in my Carrier Infinity system as it does not move much air when running on stage-1 (I have a 5-stage heat pump)Purchased this OdorStop OS72PRO UV Air Purifier for my new Carrier system that I had put in 2 years ago. I previously had another one, it was "Tinker toy" version of this one with 2 - 9 or 18w lamps in it. This is indeed a pro version with 72 watts worth of UVC killing power.The unit is packed VERY well, but apparently the carrier still found a way to break both lamps. Reached out to OS and Bridget replied and I received replacement lamps within a week. GREAT CUSTOMER service and Bridget responded to my inquiry right away.I had a noticeable difference as the air smelled "Clean" after 2 hours. I will check again in about 6 mos to see what the coil looks like, but am confident it will get the job done and will update my review if anything changes.7/21/20 Update***********Had to drop my rating back due to the following. Unit had been running for a week now. I checked on the unit yesterday morning and one of the green status LED's, that shows both lamps are lit was out. Did not mess with it at the time, but went to check on it again and both LED's were on this time. Don't know what the deal is, but figure if it was a bad lamp, it would have stayed out? Re seated both lamps to be sure. Might be the ballast is having an issue? Will watch it in the coming week and update if it is OK. Kind of worried after only a week*****12/15/20 UPDATE********One of the lamps failed after only 5 mos of use. I have contacted the company to see about a replacement as I think they warranty lamps for 1 year.******2/10/20 UPDATE*********Had to drop it another star, because for the price you pay, it does not seem to delivering any sort of long-term value. Don't know if they had a bad batch of lamps/ballasts or what, but the second original lamp has now failed after 7 mos. I can say, they were good enough to honor the 1-year lamp warranty in Dec when the first one failed and have contacted them again. Beginning to think I got a lemon!If they fail again, then I will be ordering another brand of UV light period.******6/29/20 UPDATE*********The unit has stopped working AGAIN! During maintenance, my HVAC guy said "your UV light is not working" and I tapped on it, then it came on. This was previously repaired and it either has a bad solder joint or bad relay that is sticking?Sent email to Jessica at Odor stop (again) and seeing what our resolution is this time around. NOT HAPPY to have spent $300 on a unit that has not even worked consistently for less than a year!******7/6/20 UPDATE*********Got in touch with them about yet another warranty repair in less than a year. Jessica replied and they are sending a new unit this week. Based on some of the other more recent reviews, I am not the only one having issues apparently. Hope the new one works past a year so i can get some $$ out of this purchase.*****11/20/21 UPDATE********NEVER AGAIN! WHOLE unit was replaced by O.S. on 2/22/21, now again after 8 mos. both lamps are shot. I think they REALLY have a Q.C. issue with their lamps. Would expect lamps to last min of a year. In any case, I CANNOT recommend their product at all. Checked unit and Ballast failed along with both lamps after only having the replacement since June of this year.Side note: Their customer service is great and have stood behind their warranty, but the quality of the procuct is far from stellar to keep having issues like this.

The UV lights were exactly as advertised and only takes about an hour to install. You only need a couple of tools including a drill and bits plus tin sheers and it is easy enough to install by yourself. Once installed I put some aluminized tape around the edges of the unit to make sure everything was sealed and heat would not escape around it. I plugged it in and the two green lights came on confirming the bulbs are working (which I visually checked on the other side where our humidifier and the both lights would come on every time the furnace would turn on and they would shut off when there was no air flow). I bought it to help with flu/cold/corona virus issues but it does help with keeping different odors down in the house as well. It does seem a little pricey but if it lasts and the quality is there than it will be worth it.

I was very happy to recieve OS72 to help me with kitchen and pets odor. I spend a few hours to install it in my air return duct. Installation was relatively easy and the unit started to work immidiatly. After a week of use we ask our relatives if they fill odor improvemt in our house. They did notice a little improvement but open windows are much better but not always possible. After four months the bulbs are dead but thanks to the Odor Stop custome service they are sending me new bulbs. I hope that I have to change bulbs once a year.
