KEEPOWReplacement Filter for Dyson HP04 TP04 DP04 Pure Cool Air Purifier, 360° Fan Glass HEPA Filter Activated Carbon Filter

Eternally grateful for the reviewer who wrote the following - that fixed it for me!!These filters are exactly the same as Dyson but a bargain at half the price. A little bit fiddly to fit and resetting sensor readings must be done after fitting them by holding the night mode button until you see it count down to zero and then do the same with the oscillating button. If you still get reading of 999 try vacuuming the sensor inlet slots I did and it cured all. Lovely fresh air again !!!!

This filter looks indistinguishable to the original item. They even feel the same to the touch!The four filters fit my Dyson Pure fan perfectly, and the air quality meter shows that they are working just as expected!In fact my old filters were so past their replacement date that the air quality monitor was showing a constant reading of very high particulate matter in my room.As soon as I fitted this new set of filters, it dropped to moderate, and then after running the fan for a couple of hours, it went to "good"! Definite proof that the filters work as expected.The only difference is the price which was well under 50% of the cost of genuine filters.Highly recommended!

I bought this filter for my dyson hot+cool fan and was a bit sceptical if it would fit or not and because it’s half the price as the ones on dyson. Received it very quickly and it fit perfectly and is working great. Has been on my fan now for 3 months and hasn’t needed to be changed, it’s on almost 24/7 too so I’m quite happy with it.

Ive purchased these filters from 3 different places and this one fit in perfectly. If poorly fitted ive noted alot of loss of suction. This is just as good as original as far as i can tell

Works as well as the 'Dyson' original! I will buy these again when they are 'expired'!

Appears to be poor quality as the HEPA filter constantly leaked charcoal all over the floor as I tried to fit it. The Dyson did not see the filter as having been changed.

Replaced my Dyson air purifier with this item-It filters extremely well snd the daily reports are showing good results.Initial fitting was not the best but got there !
