Product review (5 stars): Get ALOT more life out of your filter!!!
Before we tried the S1708 in our humidifier MA0800, we had to replace the filter about once per month.  I would buy a case of 6 filters for over $60 each winter season.  Since our baby was born we have decided to leave the humidifier running year round.  I have used a bottle of this and am now ordering another and have only used 2 filters this entire year.  I went to change it like normal, but the filter was like new.  The only time I've had to change the filter is when we left it off for a few weeks with water in the tank.
Great product that saves me money. Thanks Holmes!

HIGHLY RECOMMEND!!!
