Though I don't work in the fields daily, I have training and experience in indoor air quality, infectious disease control, mold remediation, carpet cleaning, water loss, etc., and own all the equipment and chemicals that a remediation company would. As part of that, I own a handful of "name brand" hydroxyl generators. Knowing how well they work, but how expensive they are, I was enticed to try these Sylvan units, of which I bought multiple, and I've been impressed with their design, build quality and efficacy. I will continue to purchase them and I highly recommend them.

Solid build quality, and unit works amazing! Just using default Hydroxyl function. Moldy odors that air purifiers can't touch were gone in ~2 days. The unit does NOT emit any odor when used without the ozone function.You can significantly increase output (and reduce time) by placing an air mover in front of the output vent, I use the XPOWER P-80A (600CFM) model ($60). You just need to elevate the unit ~2" so the output aligns with the input of the air mover, and minimize space between the two units.You can treat larger items like furniture by wrapping the item in a plastic cover, and placing the unit with the output vent inside the cover, and the input vent outside the cover. The cover should "Inflate" a bit if it's setup properly. This results in a high hydroxyl concentration inside the smallest possible space for maximum effectiveness. Combine with an air mover for even more effectiveness.This method should also be effective for furniture infested with termites (or other insects/pests), but may take 2-3 days of continuous operation to see results.While hydroxyls are technically safe to breathe, the by-products that are created when hydroxyl breaks down toxins is not something you really want to be breathing in and should be aired out ideally. 15 mins with the windows open and a fan is more than enough. And I would avoid staring at the UV light too long.I can't comment on the ozone function since I have not needed to use it. And that should say a lot about the Hydroxyl effectiveness. Ozone lingers and may irritate more sensitive lungs even after airing out the area for a few hours. While hydroxyl does not have any residual effects or odor.

I buy and sell items I get at garage sales and estate sales, etc. One of the last sales that I attended the house smelled like they didn't open the flue in the chimney while burning a Duraflame log which was strange but I really didn't think much of it as I shopped for items. I was able to grab some nice electronic items that I could flip for a great profit and was happy with my purchase but upon arriving home and opening the trunk of the car I was overwhelmed with the same smell that was in the house, uh oh. I took a whiff of the items and wow, they had the incredibly strong smoke smell that was in the house and thought there is no way I will be able to sell these and I probably will have to take a loss on what I purchased. Not giving up that easily and after searching a bit for ways to remove smoke smell from things I realized that the restoration companies used a device after house fires to eliminate smoke smells from the house and contents. That lead me to this device as I was worried about using ozone and the dangers and the fact that it had ozone as an option along with the hydroxyl I figured it could be the best of two worlds.My Process: I used a storage tub and enclosed the machine along with the items that I wanted remove the smell from and set the ozone timer to 80 minutes turned it on and closed the lid. I came back 2 hours later and turned off the machine and did a quick smell test to see what kind of progress had been made. To my surprise there was no longer a smoke smell at all but just the ozone smell (kind of similar to chlorine) that I am sure will dissipate after I let it air out for a day or two.Now my mind is running thinking about all the things that I can use this on to remove the stink from that I may have just tossed out in the past.The unit itself is really well made and was packed very well (Double boxed) to prevent damage. It is definitely a quality product. This device is really going to come in handy and I am glad that I purchased it,

Long story short great product! I highly recommend it for folks who have rental properties or need to eliminate bad odors and disinfect spaces.The photo above shows water damage near our home's foundation that was not detected early because it was under our deck. The hole allowed rats free access to our basement. They (I'm sure it was more than one) died in the walls unable to be found just irrefutable evidence of their presence (scat, pee stains, nutshells). 1 week after discovery, we had thousands of botflies (caught eventually on an agriculture sized fly-paper 12 inches wide), botflies poo also added to the stink. Full N100 respirator and PPE required to sanitize the ceiling, walls, and floor. There was still a residual strange odor. We placed snap traps and 2 months later no rats. Once we got the Sylvan HX-3000 we did 4 hours total with a break of 2 hours between with fan going (~1400SF), and voila: NO MORE ODOR!!! We love this and will use again when needed.

Bei uns in D konnte ich ein solches Gerät nicht finden, schon gar nicht zu dem Preis (auch in der Bucht deutlich teurer).Das Gerät wurde recht fix aus den USA geliefert, insgesamt knapp 14 Tage.Man braucht einen 110V Adapter, aber da gibt es eine große Auswahl von 15 Euro aufwärts.Das Gerät ist leise und wird nicht heiß, kann problemlos mehrere Stunden laufen.Sehr praktisch ist, dass man Hydroxyl- und Ozon-Produktion gleichzeitig laufen lassen kann.Mein Auto hatte einen Brandschaden, der Bordcomputer war durchgeschmort.Etliche Putz-Durchgänge reichten nicht aus und auch nach Ozon-Behandlung kam der Geruch immer wieder.Nach mittlerweile ein paar Stunden Laufzeit im Hydroxyl-Betrieb wird der Geruch tatsächlich immer weniger.Ich denke noch 1-2 Putz-Durchgänge und ein paar Stunden Hydroxyl-Generation und der Wagen dürfte wieder fahrbar sein.Ich bin begeistert.
