Replacement Hepa Filter for Dyson HP04 TP04 DP04 TP05 DP05 Air Purifier Sealed Two Stage 360 Filter System Pure Cool Purifier Fan HEPA Filter & Activated Carbon Filter

This item fit perfectly into the Dyson air purifier. Very cost effective as well.

I have very sensitive allergies. This filter functions just as well as the dyson parts and is half the cost.

I’ve bought over 4 filters from Amazon. While this one was the best price, it was the worst quality by far. The inner half of the filter doesn’t fit into the Dyson at all. The outer filter does snap in but ONLY if you remove the inner filter. I reached out to the seller and despite selling a defective filter (more than once according to other reviews), they refused to provide a resolution because we are outside the return window. I should’ve returned this filter immediately because i bought 1 to many and didn’t need it. It was such a good price and this a small business, I decided to keep it as a back up because I have 4 Dysons and would need it eventually. Big mistake. Now I’m having to escalate the issue thru Amazon and my bank. I ended up finding Dyson brand filters very close to the same price so buyer beware.

These installed perfectly and seem to be a great replacement!

These are cheap replacement filters that do fit and save money but they are not perfect fit the locks do lock but the covers don't securely lock like they do with faceup factory dyson filters. As far as what they filter with they're carbon filter and paper filter I can't really say but the percentages do drop when there's smoke or other contamination in the room so they must be doing something. The app is still saying I need to change the filters tho as it must not recognize these over factory filters

I bought this filter system instead of expensive Dyson filter. The carbon part of the filter would not snap into my Dyson HPO4. The plastic tabs bent. The paper hepa filter fit well. So basically I could use 1/2 of this filter system

Doesn't fit as well as OEM filters. Very difficult to install properly.

Had a little trouble installing but I think it’s just bc it has to be so specific to be tight. Had no issue resetting the system with the new dust free filter! I noticed that the airflow reduces significantly using this off market filter once I changed to an official (expensive) Dyson 360 Glass Combi filter (which is basically 2-in-1 new version). So basically this product is good for temporary but I recommend buying an official Dyson if you want total airflow.
