Let me start by saying, if you own a Dyson HP04, TP04, DP04, TP05, or DP05 purifier and dread the steep price of OEM filters—this CHAMONNY replacement is a game-changer. After 3 months of daily use, here’s my unfiltered (pun intended) take.

The Good Stuff: First off, the packaging deserves applause—each filter (HEPA + carbon) comes individually sealed, pristine and dust-free. Installation was a breeze; it slid into my HP04 like it was made for it (because it is). The HEPA layer traps pet dander like a champ (I have two shedding cats), and the carbon filter neutralizes my roommate’s occasional kitchen smoke disasters. Performance? Identical to my old Dyson-branded filter—same airflow, no error messages, and the app still tracks filter life accurately.

The Nitty-Gritty: Side-by-side with an OEM filter, the HEPA pleats are slightly wider-spaced (not a dealbreaker), and it lacks the OEM’s fine prefilter mesh. For my urban apartment with moderate dust, this hasn’t impacted efficiency. The plastic frame feels marginally lighter but clicks securely into place.

Real-World Testing: During allergy season, I ran it 24/7 for weeks. Air quality sensors stayed stable, and my sneezing fits reduced—proof it captures pollen effectively. The included brush is handy for quick dust-offs between deep cleans.

Value Verdict: At 1/3 the price of Dyson’s $80 filter, this is a no-brainer for maintenance mode. Just note: It won’t fit newer models (TP07/HP07 etc.), so double-check compatibility. For households with pets/allergies? Absolutely recommended—just set a calendar reminder to replace yearly.
