Product Information

New Filter Look! Optimal Performance!

Our filters have had a makeover! Although the look and color have changed, they still provide the high level filtration that helps you Create a Better Home Environment®. The new design optimizes the HEPA performance level filtration filtering 99.97% of allergens down to .3 microns. This is a direct replacement for your current filter. We have updated the design to provide a more rigid filter and changed the frame color to make it easier for you to identify our Genuine HEPA (yellow frame) and HEPA Pet Pure™ Filters (purple). We know how frustrating it can be to find the GENUINE filter in the sea of options you can find online. REMEMBER: It is very important to use only GENUINE filters made by Guardian Technologies to ensure proper performance and fit in your machine. Please don’t hesitate to reach out to our friendly US Based Support team if you have any questions regarding your filter at 1-866-603-5900 or support@guardiantechnologies.com. Thank you for your purchase of Guardian Technologies products.

Important: The fit of your new filter may vary from the original.  It’s due to the change in materials and is designed to be a less snug fit.  This will NOT affect the performance of the filter.

GermGuardian® FLT4825 HEPA Genuine Replacement Filter B is a combination filter. It includes a HEPA filter that captures 99.97% of allergens as small as .3 microns. It also contains a pre-filter/activated carbon filter layer that captures odors from cooking, pets and smoking.  It is recommended to use with the GermGuardian® AC4300BPTCA, AC4900CA, AC4825, AC4825DLX , AC4850PT, CDAP4500BCA, CDAP4500WCA; PureGuardian® AP2200CA and Black+Decker™ Model BXAP148. The use of this genuine Guardian Technologies™ replacement part will maintain the product's performance.


NEW LOOK:  HEPA filter continues to reduce allergens while the new  yellow frame helps you identify that it's a GENUINE HEPA Guardian technologies replacement filter. 

CAPTURES ALLERGENS:  HEPA Filter captures 99.97% of dust and allergens as small as .3 microns such as household dust, pet dander, mold spores and plant pollens.

REDUCES ODORS:  Charcoal filter layer reduces common odors from pets, smoking and cooking.  Acts as a pre-filter to capture large dust particles, helping to extend filter life.
