Review on 🧹 XIMOON HEPA Filter Replacements for Dyson Vacuum DC14 DC-14 DC-15 - Pre & Post Motor Filters, Part Numbers 90142-02, 921623-01, 901420-01, 904979-02, 905401-01, 901420-02 by Tina Vaughn

Filter works great and installs with no problems. As the post says, these are not OEM filters. This means they are not built to the same specs. These filters do not contain an activated carbon layer in the pre-filter. The foam material is also less dense than the original Dyson filter. Not sure if this will affect long term operation but remember they are not the same.
