Product review (5 stars): for the price of  2 filters in one pkg is a great deal and works great
i bought these online of 3 pkgs  at a time. they are cheaper yes, but they work good . they do the job as said. i had the 2 filters in my humidifier for the whole season. they did get quite yellow from the hard water the apartment complex has for city water, its  hard water. i tried using the water  from the brita filtered water it  helps but costly to use the filters for  the brita pitcher. i will  be  ordering more at the end of season for next year. great filters. this is my daughters account  with amazon. her  mother from roscommon, michigan
