Holmes HWF100-UC3 Extended Life Humidifier Filter

Holmes Humidifier Filter
Why you Need a Humidifier Filter

Evaporative cool mist humidifiers cannot run without the use of a wick filter.

Replacing your Humidifier Filter

The harder the water, the shorter the filter life. This is because minerals will get trapped in the filter over time and cause the filter to lose its ability to wick. We recommend you replace your filter every 4-6 weeks, depending on usage and hardness of water. In some evaporative cool mist humidifiers we have included a Filter Check indicator that will indicate when the filter needs changing

Remove Household Odors

The Holmes HWF100CS (E) Wick Humidifier Filter features an exclusive ARM & HAMMER Baking Soda layer to help remove household odors.

Control Dust & Dirt

This triple layer humidifier filter helps control dust and dirt build-up and helps prevent impurities from spreading by passing air through the filter.


Treated With an Antimicrobial Agent
  • This filter is treated with an antimicrobial agent to inhibit the growth of mold, mildew and odor-causing bacteria on the surface of the filter only.

{NOTE: the Holmes HWF100 and Bionaire BWF100 are interchangeable}

I bought a bionaire humidifier that uses 2 of these wicks. They're a necessary evil, because the humidifer wont work without them.

My humidifier (a Bionaire BCM645) is basically a glorified self-refilling water bowl, with a pair of wicks dangling down into the water in the lower backside of the unit ... the wicks absorb water upwards, and the humidifier (basically a vertical tube with an exhause fan up up equipped with a humidistat) draws airflow in crosswise through the body of the wicks down below in order to blow humidified air out the top ... it's a simple design that sorta works.

The problem is that mineral deposits build up in these glorified (and overpriced) sponges, and they lose their ability to wick water upwards fast enough to keep up with the rate of evaporation ... the result is that they become dried out and crusty (and slowly stained with mildew), and only stay wet on the part that's dipped in the water.

Now, here's the annoying part, and why I only gave this product 3 of 5 stars ... they're needlessly fragile by design. The manufacturer WANTS you to keep reguloarly buying replacement sponges, just like inkjet printer manufacturers want to keep selling you overpriced ink cartridges. Even though I have fairly soft water, and use a carbon block filter, these wicks only seem to last me about 2 weeks per pair, by default, before they lose their ability to absorb/wick moisture and/or fall apart. Perhaps someday someone will make longer-lasting reuseable cloth replacement filters, but as of this writing, there dont appear to be any available ... because it's against the manufacturer's fiscal interests to make and sell such.

This was delivered 2 weeks later than promised and it is not the same filter as shown in the photo. It is a cheaper version and did not have the round button attached to the filter like the original has. It had a plastic square that could be attached anywhere but really won't stay put when attached so I just left it off.
Fortunately, just by stuffing the new filter into my machine, it worked Ok. I really hate returning stuff. It is just frustrating when they show a picture and you receive something else.

I have a hard time finding filters for my Sunbeam cool mist humidifier. These are a little long, but when trimmed they work fine. They come 3 to a pack and the unit needs 2 filters at a time, so I buy 2 packages at a time.

Walmart in my area, St. Louis carries the same filter but has Sunbeam package Filter # hwf100 / sf235 for $8.00 for the 3 pack. The package says different Humidifiers that it will fit. Holmes & Sunbeam are 2 of them.

I have had a Holmes tower humidifier for several years and it requires two of the HWF100 filters. This particular model forces air through the bottom at the back and through the filters out the top. I guess like most filters, the top of the filter dries out quicker than the bottom where water is absorbed. To get a longer life from the filters I reverse the filters top to bottom about 2 times per week. This extends the life of the filter about 2 times. Other brand filters don't live up to the quality of the Holmes HWF100. Prices vary so shop around.

Good product that works well. Don't like that they put three in a box when the machine takes two. Why not two or four?

There really isn't much to say about humidfier filters. The transaction was easy and was delivered in a timely manner.

Purchased the replacement filters for my Holmes Humidifier. They seem much more flimsy than the filters than originally came with the humidifier. Unfortunately, due to the season change, I am no longer able to purchase them in store, so I purchased them online. They work, but I am not sure the quality of the filter is the same as the previous ones I had.
