Product review (4 stars): Nice replacement filter at Half the Cost
This is a review for the Replacement Filter for a Homes Humidifier.  This is a type D.  The filter arrived in a box and nicely sealed inside a plastic bag.  This filter fits my Homes humidifier well, and works well.  The only reason I did not give it a 5 star is that though it is made to inhibit microbial growth, it is not TREATED with anything to do so, so you must make sure you do not let your humidifier sit without running and let this filter sit inside moist, or you will have mold in a matter of days.  Not pleasant, and the only solution at that point is to chuck the filter and get a new one.  Unfortunately I have learned from experience.  I use a water treatment when I add water to my humidifier that helps to prevent this from happening.  It is called Bacteriostat, and I highly recommend using it in conjunction with this filter.  It seems to wick the water very well.  I replace mine twice a winter, and I haven't had any problems. It is very dry here in Nevada, so running the humidifier is crucial.  I love Discount Filter Store.com as well, and have had ordered from them many times with good results.  I received this filter at no charge/ or at a discount for review purposes.  My review is my opinion only.  I hope this review has been helpful, if so, please click "yes" below.  Thanks!
