I bought this same model here about 18 months ago and paid almost 50% more, so this is a pretty good deal.
I love the product and it saved me a lot of suffering from the smoke and air quality during the wildfires we had out here in the PNW at that time.
If all you want to do is push air around your house quietly and effectively, at this price you can’t go wrong.
Can the filter be cleaned, or must it always be replaced?
I’ve had this as well and I had purchased here however my problem was it it just never seems to be enough a regular fan works better and I don’t know if the purifier works that well I didn’t see any proof
filter needs to be replaced every year
biggest problem I see, the air that flows through as the fan runs, is not filtered. The only air filtered is what is pushed through the filter.
I just looked in 2020 it was the same priceI had purchased a fact then it came in kind of made up lots of scratches and had some issues so I ended up returning it
Good deal. We’ve had one for a couple of years. We use it in our living room. Wanted a fan that was relatively attractive due to this and the fact that we watch TV in there, so did not want the noise. I can’t vouch for the air purifier whether it is ‘effective’ but it does seem to keep the dander down (2 cats) and the filter does get dirty 
I’ve had this fan for over a year. I have a heavily automated Smart Home and this barely integrates with it.
+Nice design
+Nice remote
H when you turn it off and turn it on it remembers the speed it was at but it is not remember the oscillation setting
Working through a home automation system such as Google homes is very difficult. To get the oscillation to work took a lot of work to find the right word to use in a script. It worked for about a year and then suddenly stopped working. You’re paying a lot of money for a Wi-Fi enabled fan but their software is pure crap.
As summer comes we need another fan but we’re not going to get this one, even on sale. It’s very sad they can’t find an intern to make this software right!
I just pulled the trigger. I’ve always thought these were way too expensive but I still always wanted one. I’ve had multiple Dyson refurbs and all work and look as expected. Hoping this is the same!
I got a Dyson fan in my office. Quieter than regular fan, air flow is about the same. Probably wouldn’t have bought it if it weren’t for an expense account that I had to spend or lose the balance…
Oh the beauty of misguided incentive systems…
I have not changed mine yet, but I don’t think so.
My guess is that it would damage the hepa filter part, but I’m not sure.
In theory, you can clean the filter by using a brush (make sure you are outside or it kind of defeats the purpose…) to dust off the filter.
However, you really should just buy replacement filters, since mold spores (and other germs) can collect in the filter and eventually grow, then your air purifier will become a mold/germ amplifier.
The actual fan is in the base, it points upward into the big oval. The circular filter surrounds the base, so anytime the fan is spinning, it’s pulling air in through the filter and pushing it up and out through the oval.
If you think that this is using some type of magic spell to accelerate air in one side of the oval and out the other, you’re mistaken.
So it’s not magic?
Well this is disappointing news.
Your question prompted me to check on mine, which is actually a model TP04 and not a TP02 as this one is. The filters are different, and the TP02 filters are a little less expensive to replace than my TP04.
Washing and reusing the filter could probably be done, but I’m sure you’d find their effectiveness fairly diminished.
