  • What buyers say about Germ Guardian FLT4825 HEPA GENUINE Air Purifier Replacement Filter B

    The package looked the same, but I saw a review that said the filter looked different, but this doesn't seem to be the case.

    My husband bought an air filter machine for my daughter a few years ago, but it wasn't working as well as it could, so we needed a new one.

    They are a perfect fit and feel good, high quality filters with a nice snug fit. Only time will tell how well they hold up, but as of right now I have no reason to believe that they will be anything less than perfect.

    It is recommended to change the entire filter every 6 months, which is right when the light came on. After changing the filter, hold the UV button down for about 5 seconds, and it will reset the light.

    The customer service at this company is very good, and I like that I don't have to call very often, but the two times I have, they got back to me quickly and resolved the problem.

    Common Questions


    I don't see a reset button, the red light is still flashing after I put in a new filter.


    I saw writing on the top of my unit that told me to push the UV button and hold for 5 seconds, and that worked for me.


    Can the pre-filter be sprayed off with water, as we use it next to the cat litter box?


    I keep the pets clean as I can, but I have to save money when I can. I vacuum the filter at least once a week and I take the black pre filter off and just lightly rinse it in cold water, and squeeze it as dry as I can.


    How many times a week do I change the filter?


    I had mine for more than a year and I haven't changed the filter because the sign never came up.


    Do we need to buy another one if we only need the one that has the black and white part?


    Yes. You need to buy another one, but if you keep cleaning it will last about a year.


    Does anyone know what the voltage is on these items or if they are an energy saver?


    I run this 24 hours a day for the past year and my electric bill hasn't gone up.
