Fette FilterPremium H13 True HEPA Replacement Filter J Compatible with GermGuardian FLT5900 for AC5900WCA & AC5900WDLX Air Purifier includes 1 Hepa 2 Activated Charcoal Filter.

I was initially concerned about the fit with any kind of replacement filter. This was the first one I tried and it fitted fine and worked just as good as the original filter that came with my GermGuardian. I will probably try to buy filters in larger quantities next time to save.

Fits perfectly with My germ Guardian air filter.Can see it catching debris in just day 1 use.I feel happy with the product.Feel the product is a bit costly.

Second time purchase. Great value for the money and better air filtration quality for the price too. I was disappointed in the shipping time estimate but was pleasantly surprised when it arrived at least a week earlier than the estimate.

This is a good alternative to the expensive one they tell you to get. It comes with the carbon piece to it, so you have everything you need. Definitely purchasing again.

When installed I noticed a small gap around the edges. When I put the panel back on and hit the power button it wouldn't come on because this replacement filter is to small to recess the pressure activated switch. I had to use duct tape to hold down the switch. I'm concerned that particles will get past the filter around the edges.

This filter fits as well as the factory original. It seems to work about as well. I can’t measure fine particles in my air or anything, but I still don’t have to dust very often, and it clearly catches a lot of junk from the air.

Fits perfect. Price is great and the quality is as good (maybe better) than the brand name, and it comes with an extra charcoal pre-filter. I'll be a regular customer, for sure!

We bought these filters since it seemed to be a good replacement filter and we're happy with the outcome - we'll be purchasing these again in the future.
