I bought this end of 2019. I loved it. Filters are expensive but it worked really well. So yesterday it stopped working and has the exclamation mark with a triangle around it. I tried resetting but it won't stay on long enough. Unplugging it and plugging back in. For the price you pay... Only 3 years of use is crap in my opinion. Warranty is only 2 years. I won't be buying Dyson products ever again.

We used this air purifier rarely, only one summer and it started making mechanical noise on power up and it wouldn't run. Contacted Dyson support as the fan was still under warranty. After series of emails, it was concluded that it has failed and replacement unit will be sent. This was in March of 2022, now is almost November. There was no attempt to repair, nor replacement unit was ever sent. At this point the support doesn't even respond to emails. I understand that there could have been supply chain issues, but this should have been resolved by now, and alternatives offered or refund given. Instead we just get an email saying that when unit is available the replacement will be sent, which at this point will never happen. There are products at the lower price range that are more reliable and the companies that actually honour the warranty. I would not buy their products again. An overpriced product for average performance and quality.

I wish I had this sooner. I’ve had it nearly a month now & have noticed quite the difference in my apartment.
