After a year, I'm pretty happy with this purifier. I live very close to where the 2025 fires were in Los Angeles. The smoke was awful outside, but things seemed OK with the G714 running inside. Day-to-day since then, things seem fresh even with multiple cats (and a sensitive person) in the household. This purifier was a huge upgrade for me compared to the types of HEPA air filters I've bought in the past, so some things took getting used to. In particular, these units intake air through lots of small holes -- no large gaps or areas that trap hair and need to be cleaned regularly. It was confusing not to have that visual indicator that it was "working." On the other hand, the goal isn't to get big hairs (that's what vacuuming is for!), but keep smaller more dangerous particles out of our lungs. It's also an adjustment not to change the filters as often as cheaper units. It's convenient, of course, but made me wonder at first. The filter seemed to stay surprisingly clean the first couple months and I was questioning if it was really doing its job. After almost a year when I took things apart (and shook out the prefilter outside) it became clear that it had collected a lot. Speaking of taking it apart, the screws seem a little finicky when you need to change filters, so make sure you have the right screwdriver or wrench and take your time so they don't strip. Fortunately you don't have to open it very often, and the upside is that the whole device is very sturdy and seems built like a tank.
We were so pleased with our first P714 in our apartment, we just acquired our second unit for our home. Built to last, effective and serviceable - these purifier is quiet enough to run nearby, unnoticed in our living spaces, not only removing dust, but also odors and viruses. Excellent!
The pre-filters for my AIRPURA C600-DLX are so simple to change. I had feared it might be complicated, but it is so simple. Just unbolt the four screws on the base, remove the filters and line the unit with the new one. It's ingenious how a paper sheet acts as a funnel to reinsert the carbon filter without catching against the pre-filter and moving it out of position! So simple! I vacuum the outside of my unit every few months to pull out any excess dust from the filter helping it last longer. It's a very effective product and highly recommended!
I conducted a lot of research before buying this UV614. I wanted something to help me with mold allergies, and also pet dander. My bedroom smelled completely different after running this unit a few hours, and I noticed I had better sleep quality almost immediately. I also love that the unit has simple to use controls. The dial is easy to turn in the middle of the night as I don't have to find a remote or turn on the lights to operate it as I did with the Dyson before it. It also has a very nice white noise. All around this was more than worth the purchase price. The unit also seems to gather less dust than the Dyson, perhaps because it is bigger. I have had this for 8 months now and it has been maintenance free.
I have bought 3 of these purifiers, one for a friend, one for my daughter & one for us (UV600). It is very reassuring to know this is running & keeping our small home free of contaminates. I believe there may be a mold problem also, so the UV light is an added comfort.
