    Sometimes it just doesn't pay to purchase a after market product. If you want a perfect fit you need to come back to the company that makes your humidifier. And the Aprilaire filter fits perfect

    This filter is much too difficult to install and to determine if it is actually working. I hope it works and that I don't break it installing the filter. Improvements are necessary on this product.

    We are happy with your product and service. Do you have tablets to put in the humidifier to retard the growth of mold? That has been recommended to us.

    I bought 2 filters direct from Aprilaire via the company website. The next day I found the same filters being sold (brand new)on Amazon, for 35% less! Aprilaire should not charge its customers a premium for the privilage of shopping on its website! Buy at Amazon.

    I had the help of the old box to know what to order but besides that your web site is very good and customer service and notification very good also. I hate it when a company has a good site and changes it for what reason can only be guessed at. So good job to you!

    It's best to have the branded filter and know that it will work best. It's pretty easy to install - and you clean the unit at the same time.

    The product arrived in prompt time and in good condition. I found that turning down the water flow has helped with build up of minerals in the panel. Appreciated the free shipping offer.

    Second time for ordering the replacement water panel. Great service. If all on line ordering was as easy and as clear as Aprilaire's web site makes it, everyone would be ordering everything online, especially people who don't have stores conveniently located near their homes. Thanks.

    Super fast shipping and worked like a charm; our house now has 42% humidity. Turned out the switch was broken on our unit and when we replaced the filter we found that out. Our house is now very comfortable in this cold weather.

    I initially telephoned your company and spoke to a young man on May 5, 2010 after 3PM who advised me the only way to order this product was online. I then telephoned back at 3:50PM to advise Phyliss about encountering difficulty with the one distributor I called who only wanted to install via a "service call" and Phyliss offered to place the order for this product over the telephone. I commend Phyliss for her high level of customer service!
