Review on 2-Pack FLT4825 True HEPA Filter B Replacement with Activated Carbon Pre-Filters for Guardian Air Purifier Models AC4825, AC4300, AC4800, AC4900, AC4850 by Christopher Millet

Revainrating 5 out of 5

OE quality filter

This should last a while, I've used it for about 2 months and should last another 6 or more. The activated carbon filter should be replaced every 2-4 weeks, and the lifespan of the HEPA filter is 3-6 months. It's perfect for my germ protection and quickly removes unwanted odors while the carbon filter is fresh. If I still smell the smell quickly and after a minute I change the activated carbon filter. In general, the quality is the same as OEM filters, but the price is much better than OEM filters.

Pros
  • Durable finish
Cons
  • High price
