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

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.

If you think this is a replacement for the one that comes with your air filter you are wrong. This is filter cloth but it looks as though someone free hand cut it with scissors including the wrong angles and thin pieces hanging on the side from bad cuts. they also do not have the Velcro boarder that sticks it in place. does it get the job done yes. Other side is look how much you are paying for it because thats what you would be getting for that price. Works, ill probably buy it again but dont expect perfection.

Does the job its designed for.

Ive been guilty of buying the name brand filter replacements for years. But after finding these filters, I will never go back! These filters seem to be more densely packed to create a better filter than the originals at a fraction of the price! I highly recommend these to anyone with the correct germ guardian filter!

Great filters. I love my purifier machine germ guardian.

Worked exactly like it was ment to, easily installs

Direct replacement, fits perfectly.

Great product delivered quickly at a great price.

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.

Was able to cut to fit to replace filters from my old air purifier that became unavailable. Works good.
