I've kept my filter FRESH and stinkfree for 5 years

2009-02-08
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.

gotta buy 'em

It's a shame that these filters cost so much, I'd have sworn I paid more like $7 each for them last year, but they are worth buying. I have the humidifier which works very well, and we haven't had any trouble with it, but I sure wish the price would go down!
And gasoline, too...

Short-lived

The filter lasts for about two weeks, after which it turns completely useless: it stops soaking up water more than two inches from the bottom (the rest of it remaining dry as the Sahara desert), thereby rendering the humidifier totally useless at any speed. The cost of filters for a single season is more than the price of the humidifier itself.

Exhorbitant rise in price

Price rise from last year 6.99 to 15.00 this year. Disgraceful.

works okay, but for a price

If you're on Amazon looking to buy these filters you likely have bought the Hamilton Beach humidfier at a real store and now need filters, only to find your real store doesn't stock them.

I've had the HB humidifier for a couple of years and have used many filters; they are *very* expensive for what they are. They are cheaper if you buy them direct from HB (or even third pary sellers through Amazon), but by the time you pay shipping with the other sellers it's all pretty close. The expense of the filters though is an important point to consider if you are considering to buy this type of unit. If you need whole house humidifying all winter long it's not the right choice; if you own your home vs. renting have a whole-house humidifier installed.

As for life expectancy...one can read the reviews and see that some people have a few days and some people get a few months from one filter. This is all a function of your own water and air quality. If you've got rusty water don't be surprised if your filter is yellow in a week, yk?

Also, I've seen several reviewers saying they're trying to humidify their homes to 50%. This is probably too high for ordinary winter use in cold weather climates. Anything over 35% and you're going to get condensation on your windows which will freeze if it's cold. I have a whole house humidifier (something your furnace/AC guy has to install); its maximum setting is 35% and the colder the outside temp is the lower they recommend you set your humidistat at. Anyway, I use my HB room humidifier in the bedrooms of my kids when they have a bad chest cold. The extra moist air helps them breath and soothes irritated airways. But it's just for bedtime, and only when they're sick. My unit has no problem making one bedroom as moist as I want it short term (50%); I think in a large open space it would struggle.

First of all, I have soft water at my house. The hardness of your water supply will affect how dirty the filter becomes. As long as the filter is turned upside down after every fill-up it does last for about a month and 1/2 to 2 months. I also purchased a warm steam humidifier which we prefer over this cool air type. The filters need to be replaced a bit sooner, but they are cheaper to do so.

The humidifier did the job for me, keeping one room at 50% humidity and helping with the rest of the house too. Quiet and easy to look after, I have not had any problems in two seasons of use.

If you have hard water, the filter will only last about 3 weeks. I have found that I can rejuvenate them overnight by soaking them in dilute hydrochloric acid, but you need to know what you are doing with powerful acids. As an alternative, you can probably get more life out of the filters with conventional kettle defurring products such as vinegar, but I haven't tried them.

Keeping up the humidity in winter allows a lower comfortable temperature. Helps if you have dry skin and is essential if you have delicate wooden things like a classical guitar. Well worth the trouble.

Some Suggestions from a long time user...

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.

Too Expensive

All the bad reviews are right on. We may have to use this and put up the cash because i havnt found anything else, but the filters only last a short while if cared for perfectly. If not cared for perfectly you risk hurting your kids health.
