Puroxygen P500

Update: So we heard back from the company and after several attempts at troubleshooting the air purifier, they are now replacing it with a new one. I have to say we were very pleased with their responses, help, etc. We were fully anticipating that we would have to eat our losses on this one, but thankfully, there are still companies out there who strive to provide good customer service and this is one of them. Although our original unit didn't make it to a year, we are glad they are sending us a new one and will keep you posted as to how it goes with this replacement! We purchased this air purifier on November 3, 2024. To date, it has done exactly what the manufacturer said it would do. It can get a little loud if the air quality changes enough that it needs to clean the air, but overall it's not horrible, and you can easily adjust the fan level if necessary. We tend to just leave it and let it do what it was made to do. You do need to remove the filter and vacuum any dust off of it periodically, which we have done. You will know when you need to change the filter, because a light will come on, indicating it is time. The filter change is very easy and compared to filters you purchase for say humidifiers, the cost of their filters isn't terribly expensive. Things have been working fine until this week, and now our PM numbers are way over the normal limit and the indicator light stays red. No indication that the filter needed to be changed. We unplugged it, vacuumed the filter per usual, placed the filter back in, removed the side sensor cover and cleaned it per instructions, plugged it back in and same results. I had a new filter on the ready, so we thought let's replace the filter to see if that would resolve the issue. Same result. There is some sort of new odor, which smells more mechanical, almost like an overheating smell?? Reached out to the manufacturer to ask what is happening, and we are hoping for a response. It's almost a year since we purchased this, and we really don't want to have to replace it already. Hopefully we will get some good news from the manufacturer.

Afted 3 months it stopped working which is really a shame for it's price. Used it 3 to 4 hours daily which shouldnt be alot

I have asthma and I was having problems breathing last summer because of the forest fires in Colorado. We live in Colorado, but we also got smoke from New Mexico and Utah. Even people without asthma were suffering. I did a lot of research on air purifiers and found the PurO2xygen air purifier fit our budget. I was pleased with their quality and their performance. The purifier has a nice display at the top that shows a colored circle and a numerical readout that corresponds to the air quality. We purchase two units and found it reduced the smoke and particulate pollution from a red (worst air purity reading) to a yellow, to a blue and finally to a green (best air purity reading) in a very reasonable time. We noticed how quickly it worked when we accidently burned something in our oven and triggered the fire alarm. The purifiers had already indicated a change in the air before we could smell it and before the fire alarm was triggered. Again the purifiers brought the air quality back to a level that was breathable in a surprisingly short period of time. The purifier have the capacity to move air quickly through them using the fans top speed. At night we use the sleep mode, which is the slowest and quietest speed and the led display is blacked out. This is perfect for sleeping. In summary, I am very pleased with their performance and certainly have no qualms about recommending them to others.

I changed the rating from one star to four. Just after posting this review I heard from the manufacturer. They sent instructions on how to clean the sensor, which resolved my issue. They did not respond to my question about the app. There was nothing in the manual about how to access and clean the sensor, so that should be addressed by the manufacturer in the documentation. I purchased this unit along with a pack of replacement filters. I changed the filters every six months as per the instructions. It worked well, and as near as I could tell the air quality indicator was somewhat accurate, a couple of times when we burned something on the stove or when I had to cut some wood in an adjacent room creating wood dust in the air the air quality would decrease, and then return to normal after a time. However on the third filter change the indicator only displays the worst air quality all of the time. Attempts to reset the filter timer as per the instructions do nothing. Removing the filter still indicates the worst air quality. While it is possible my house went from a good quality to the worst, it seems unlikely. I sent a support request on the manufacturers website and got an automated response and link to see if the case was updated. The link just returns me to the manufacturers web page and I never received any responses. One other thing that was annoying, is that there is no app in the App Store as per the description, and there are no instructions on the manufacturers website on what app to use or how to connect it. This makes me question if the unit ever even worked as described at all, or if there was just a display with lights and numbers and a fan. Even if it had failed after warranty I would have bought another unit but I do not have faith that the manufacturer was ever really invested in this filter.

I lived in an area that had really bad wildfires throughout the summer and fall. This purifier has been a life saver! Being able to adjust the fan speed depending on how bad the air was that day is very convenient. It is also quiet enough that it doesn't bother you during the night. It's sleek and the perfect size to fit along the side of your bed.
