germguardian Guardian Technologies FLT41002PK FLT4100 HEPA Replacement Filter E for AC4100, AC4100CA AC4150BL, AC4150PCA, 2 pack, Black Air Purifier

The Air Purifier is a great machine, small in size but puts out a strong volume of air. I put the machine on the top of the shelf just below the furnace and air conditioning vent that exits near the top of the ceiling above the bedroom door. Often times we have to reduce the airflow of the purifier to the lowest as it cools the room down too much during the night. Above all all it quiet on all 3 settings and makes it very nice to have on during the night when we are sleeping.

These are great. I have pets an allergic to them an these are great. I have 2 sizes of these air purifiers an they are the best. The filter I like. Bought off brand these are best!!!

I was a little skeptical about how much this would purify the air. Then i replaced the filter & WOW! what it filtered out was amazing! The picture makes it look like a brick pattern is on the filter, but no— the white is actually all the garbage that it filtered from the air! I definitely felt that my allergies were improved this spring/summer, but thought that maybe wearing a face mask at work helped too. In any case, it does the job, easy to replace filter. Literally about 10 seconds.

Not much to say about this. It goes with the air purifier I am using and it fits perfectly and does the job! I was impressed at how much dust and crap it filters out of the air, and am very thankful for it as my workplace is the worst when it comes to dust. Great product. Will be buying more as long as my air purifier works!

You can reorder easily and you can wash the black filter and not have to replace the entire filter so much.

I always need this replacement it works so well

Small air filter, but does a great job of cleaning up the air you breathe. I’m a smoker in two rather small Rooms. I turn this unit on while smoking, & turn it up higher in the evening before going to bed. The air is clean in the morning. I don’t smell nicotine when I come downstairs. I love this little unit. Small, but effective!

I really like my table-top filter. Judging by the discoloration that happens, I would say that the filter is taking a great deal out of the air in my apartment. Between allergens and other current health threats, I am glad to have these filters cleaning much of the stuff in my air.

Easy to install, not terribly expensive and does what it is supposed to do. The amount of dust it catches is amazing.

The charcoal fabric filter could be more sturdy, after a few washes it loses its shape & integrity.
