TP04 Replacement Filter for Dyson HP04 TP04 DP04 TP05 DP05 Air Purifi-er Sealed Two Stage 360° Pure Cool Fan Combi Glass HEPA Filter & Activated Carbon Filter (Not for HP07,TP01,TP02,TP07,HP09)The Forest Stewardship Council

Works great and fits like it should. Air quality seems good after installing and best of all, it was almost half the price as the name brand one.

Was a little tight to install, but it works well at much less money. I will definitely replace it with this one again. The two pack is the better value, but I only bought one to try before spending more money. Next time two pack it is!

Priced-right alternative to Dyson filters. They fit perfectly and work just fine.

Great value but tough to get the filter to fit into my machine. But once it fits you are good.

I have the TP7A Air Purifier and Fan with Autoreact -- So, there is a lot to say because I feel like buying an off brand can be not worth the time or hassle. Not the case here! I was not willing to spend $80 on one filter from the name brand's website when I did my research into what type of filter it was and what would work overall. Here buying two for $60 was so much better! It was easy to install the new filter. I did have to reverse them because they originally didn't click in. Didn't know if that was actually due to the filters or just me not wanting to break them because I was being too cautious (not saying they are flimsy. all filters are fragile, and I didn't want to damage them in case of returning them). However, after reversing them, fit in perfect. Easy as click, click, click. Turned on the purifier again. The filter still read as red and needing changed, but I got no error or anything alarming. I read from the manufacture's website while doing my research beforehand to make sure you reset the filter after changing it by holding the 'night mode - moon' button for five seconds. The machine will count down and then give a check mark and go back to green. Like I said super simple.

Just make sure you have there correct model number. I had to call the company to determine what mine is, as it was a gift. It worked like a charm, but you do need to download the App because there were specific instructions on what to do after the filter are replace. Nothing big, but apparently necessary.

Great quality. This was my second set of these filters for my Dyson fan. They were a perfect fit and held up as well as the orginal.

Fits well with my TP04 model air purifier, however these things STINK for the first few days. Filter had a musty, plastic smell to it that really took up the whole room for about a week before the scent dissipated. However in the interest of saving a few dollars versus buying brand name Dyson filters, it's still worth the annoyance.
