Carbon Activated Pre-Filter 4-pack for use with the Germ Guardian FLT4825 HEPA Filter, AC4800 Series, Filter B By Complete Filtration Services

it came with the fold.

I like the way that it captures all the dust in the air. Works well with my Germ Guardian air filter. I dont notice the air being fresher though. With the way the carbon should work. Overall happy with this filter cartridge. Would buy again.

I am extremely allergic to dust and these catch a lot of dust in my air purifier. I ought these because after I rinsed out the first one that came with the filter, I really did not want to put it back on.

I bought these to replace the outer charcoal pre-filter for the GermGuardian AC4825. The filter is cut to the exact size and it sticks very well to the velcro. The material is at least twice as dense as the original filter so will definitely help to filter out more large particles. However, I do worry that the density of the material will put extra strain on the fan motor. I guess Ill find out.

They’re ok, not original the ones that came with my air purifier are not as thick, they are softer, these work but seem to make my purifier noisier.

Product arrived day before expected delivery. These prefilters are for my Germ Guardian Air filter. They are a tiny bit bigger and a little thicker but fit fine. Very happy with them.

This toilet bowl cleaner is the bomb. It makes it much easier for me to clean the toilet. It has enough cleaner that I can clean 2 toilets with one wand.

Fits as intended but feels a bit different than the stock one and doesn’t stick as well to the Velcro on the machine but works well

I am beyond pleased with this product. I have had asthma since 18, now 31, & over the past 2 years Ive needed to use my rescue inhaler anywhere from 2-6 puffs per day! THE FIRST NIGHT I TURNED IT ON, IT WORKED. I didnt use my inhaler after work, before bed, or after I woke up in the morning! Its quiet, compact, and light - which makes it easy to move from my living room to bedroom. I would absolutely recommend this air purifier to anyone.

The filter is a great way to extend the life of my HEPA filter. Right after the 4th of July I checked the carbon pre-filter on my air purifier. The particulate matter from all the fireworks near my home had really coated the old carbon pre-filter. It was great to be able to quickly change just that bit to extend the life of my HEPA filter. Its sill important to regularly change the actual HEPA filter, but I feel that changing the charcoal pre-filter really does help to extend it for a short time
