Amazon.com Review

In arid climates or the cold, dry days of winter, owning a humidifier makes an awful lot of sense. A humidifier protects household occupants from static electricity shocks, prevents dry, itchy skin, allows stressed lungs to breathe with more comfort, and infuses the room's environment with needed moisture to furniture, fabrics, and plants for long-lasting health. But for all of these positive attributes, using a humidifier may also produce some nasty and harmful results. If not properly cared for, a humidifier becomes the breeding ground for assorted viruses, bacteria, mildew, and mold. In other words, the soothing moist air exhaled by humidifier might be much more harmful than helpful in the long run. To keep the air clean and amply humidified, it is essential to regularly replace the humidifier's filter, where the impurities often fester. Hamilton Beach recognizes the importance of clean filters by offering this replacement filter from their True Air line.

The filter fits Cool Mist models 05520 and 05521. These humidifiers accommodate rooms up to 1200 square feet and feature a 4-gallon output per tank. The filter drops into the tank for simple installation. Filters should be replaced every three months and humidifier water changed weekly to ensure clean breathing air. The Cool Mist humidifiers are also dishwasher- safe for thorough, regular cleaning. To extend the filter's life, some users swap out filters weekly to allow the spare filter to dry well to keep mold from developing. Rotating the filter also may prolong its life. No warranty is available for the replacement filter. This item measures 11.1 by 6.8 by 3.1 inches. --Jessica Reuling

5.0 out of 5 stars I've kept my filter FRESH and stinkfree for 5 years, February 8, 2009

This review is from: Hamilton Beach True Air 05920 Blue Humidifier Filter (Kitchen)

I have been using this humidifier for 5 years. Here's how I keep the filter fresh.

I fill the tank at night before bed, run it on low, and by the next night the tank is empty and the filter is all dry. I flip the filter, fill the tank, and start over again. If I need to add water more frequently (on a dry day or if I want higher humidity), I still have to LET THE FILTER DRY OUT and FLIP the filter BEFORE I add new water.

So, I run it 24/7, and it lasts about 7 to 8 weeks because
(1) I let the humidifier run until the filter is bone DRY for EACH tank of water.
(2) I flip the filter every time I put a new tank of water on it.
(3) I put the tank and tray in the dishwasher once every 7 to 10 days.

These are what the instructions say to do, and I have found it WORKS! I need two or three filters per season.

If you keep adding water without letting the tray and filter dry, your filter will get stinky and yellow in 2 weeks and you will be unhappy!

If you find the filter is soggy, let the humidifier run until it dries out. Make sure there is no water in the tank and tray, and it will dry out faster in the humidifer (20 - 30 minutes on high?) than in the air.

Don't be unhappy: let the filter dry out between tanks.

3.0 out of 5 stars Some Suggestions from a long time user..., May 6, 2007

This review is from: Hamilton Beach True Air 05920 Blue Humidifier Filter (Kitchen)

First - the reviewers that recount experiences of bad smells from their filters need to undrstand that wick humidifiers, like the HB 05920 and 05921, require that an anti-bacterial solution be added to the water tank when filling. This solution, I use "Golden Solution" (try Google), prevents mold and algae from forming on the filter and in the tank. This prevents the odors and gets you a couple months out of your filter if you run your unit 24/7 like me.

Second - there are other replacement filters on the market that are the same size as the HB True Air replacement filter and cost half as much.

I use two HB True Air humidifiers and usually stock up on 4 filters each for the 6 months they run continously in my loft. I have a couple True Air filters and a couple Best Air filters right now and cannot tell the difference between them when it comes to performance. The name brand True Air's keep their shape better, but for nine bucks, I'm not worried about the asthetics of the inside of my humidifier.

Hope this helps those who use these filters.

I've been through so many humidifiers that get moldy and nasty so that you just have to throw them out. My sister spent a lot of mony on a Hunter that is supposedly clean free, but it always had mold in the standing water when I lifted the tank for refill. This Hamilton Beach is a wonder. I use it every night year round. If you follow the directions and put the parts in the dishwasher once a week and turn the filter every time you refill the tank it works like a charm. The only time I have had a filter go bad is when I go on a trip and it just gets moldy. I haven't found a way around that. But otherwise, I can use one for months without a problem. It's all in following the directions. And it helps to change the water in the tank at least every other day. I recommend this item to everyone.
