Discount BWF100 Bionaire Humidifier Wick Filter (3 Pack)

Customer Ratings:

{NOTE: the Holmes HWF100 & 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.

You can save money 2 ways:

1) SHOP AROUND: you can save as much as 50% by shopping around for the cheapest supplier, and scoffing at any implied manufacturer product loyalty. How ? The replacement filters for Holmes (HWF100) and Bionaire (BWF100) are functionally identical and interchangeable. They come 6 to a package (3 pairs).

2) RINSING: These wicks are rather fragile resist the urge to wring them out when rinsing them, or you'll damage them. Instead, fill a sink with body-temperature water, let them soak for 5-10 mins (to let the deposits soften & par-dissolve), then gently press them flat (while submerged) a few times. Then drain them (dont wring them) and reinstall. That should extend their performance by another week or so. Each subsequent rinse will yeild only half the benefit though. At best, you'll be able to double their lifespan.

Bottom line: I dont really recommend these wicks ... but if your humidifier requires them, there isnt much choice. However, if you use the tips I listed above, you can save up to half the cost, and make them last as much as twice as long.

I did not buy this item. But I did want those who use Bionaire humidifiers to know that there are new filters available.

Holmes replacement filter HWF100 can be used in place of this item and is available from several sellers (at a lower price than this used item) including Amazon which currently offers free shipping.

I ordered these filters for my humidifier because last time I bought the knock-off brand filters and they only lasted a very short period of time. My humidifier takes two of these filters at once... the first thing that disappointed me was receiving 3 filters... I for some reason assumed this listing meant you receive a 3-pack as in "3 replacements worth"... but I was wrong, you actually get 3 filters when you buy this. For me, this is dumb, because my humidifier takes two of them, so I'm left with an extra filter... now I have to buy another 3-pack to make it even.

The other thing that is a little weird is that this seller "cd_cellar4" doesn't include the original packaging when they ship these filters, you just get 3 filters stuck in an envelope, so there's no definitive way to be sure you received true Bionaire-brand filters, and not another knock-off brand. And, the postage they paid to ship the filters is clearly marked as $1.90 on the package, even though you get charged $4.49.

Honest reviews on BWF100 Bionaire Humidifier Wick Filter (3 Pack)

I've had an impossible time finding replacement filters for my humidifier, and this was another failed attempt. The filters that I received do not look like the one that is pictured the ones I received are clearly a cheaper version and do not have the little round blue tab that is meant to lock the filter into the humidifier. They don't quite fit into my humidifier I shoved them down in there to make it work because I didn't want to mess with returning them. I won't buy these filters again and won't buy another Bionaire humidifier (why make a product if you're not also going to make replacement filters for it????)

My Bionaire humidifier is not new. I've been happy with it for about 3 years. But once I ran through the filters that came with it, I found I had trouble getting replacements. For awhile I could buy them at a local store, and then when they stopped carrying them I tried the internet. I bought some through Bionaire, but that was a hassle. So I was very happy to find that I could buy them through and I've had no problems since except maybe that they appear to be 'off brand' rather than Bionaire filters.
