Nice filters
These are quality filters. Worth spending the extra money.

Good Quality Filters
I bought these to replace the filter in my humidifier. They hold up as well as the original filters if not slightly better. I find that one filter lasts most of the cold season in the US Midwest and towards the end I need to replace. Highly recommend.

Way better than the ones without the blue!
We were going through the other filters without the blue extra layer in easily 3 weeks (they would start to smell even when we flipped them on each water tank refill, which in winter was 2x a week) so definitely think these are worth it. Going on probably a month with one and noticing far less yellow/no smell

Replacing Your Filter is Essential!
If you have any humidifier that utilizes a filter it is essential to replace it regularly for continued proper functioning. While you could use it without a filter, there is a reason they have filters and that is to improve the quality of the air being circulated in your room.Nearly a year ago I bought a black Honeywell HCM-350 unit on Amazon. After about a month of nightly (8-12 hours) use on the highest setting I noticed a slightly different smell in my room (not bad, just different) and noticed that the water reservoir was not emptying as rapidly as it had initially. This was because the filter was in need if replacement. Over the month of use the filter hardened up and was discolored. As a result, less water was able to pass through the filter meaning less moisture was being pumped into my air, and presumably the air that was getting out was not as clean as it could be.Replacement is incredibly simple and after the first night I noticed an immediate improvement in the functionality of my humidifier. The water reservoir was significantly lower and my room smelled a bit fresher as well.In my opinion, if you are buying a humidifier unit like these that utilize a filter then you really should be prepared to regularly replace the filter. I know it can be a bit off putting to spend $10 every month but it is worth it. There are lower quality humidifiers available on Amazon and elsewhere that do not use filters, so you may consider those for a cheaper option. But if you want to step up to slightly higher quality or if you are very sensitive to air quality then you should be prepared to change the filter AT LEAST every month, maybe even more frequently if you are very sensitive.

Outlast all the cheapo brands
After wasting money on all the off brand wicking filters I went back to the OG filters. Yes they cost more but they last longer. With the off brands I could get up to 50% occasionally and then it would drop off to the low 40’s and degrade from there. I maintain a high 40’s using the Honeywell brand over a longer period. I just ordered a 3 pack, the last 3 pack went 4 months and the last one still doesn’t need to be replaced.

They work
These filters improved the performance of the original filters in my humidifier by a measureable margin. I don’t normally write reviews but these work enough to compel this review.

It Fits and Sits!
I bought this to replace the old filter in my Honeywell HCM350 humidifier, and it fits perfectly. I’m not sure if the blue pre-filter makes a huge difference, but it works at least as good as the original one that came with my humidifer!

Best Longevity and Durability
The blue outer gives me pause, as it’s some kind of plastic, but the upside is that these last longer than the single-layer paper wicks (filters, as some call them). The KEY is to CLEAN them weekly! Obviously, all houses are different, but I can keep one going for about two to three months, and they run 24/7.I have three Honeywell humidifiers going through the winter, and we have used the blue filters for at least two years now. I don’t want to go back to the paper-only wicks, even if they’re cheaper. But cleaning is crucial, and either type will last longer with maintenance. My goal is to change the wicks once per season. Occasionally, I have to put in a third toward the beginning of spring if we keep using the furnace.How to keep ’em clean: Take the top off, take the tray to a full sink (or clean bucket,) put a tablespoon of bleach in water, drop a wick to sit in the treated water for 10 minutes, gently slosh it around, then empty/refill the receptacle with fresh water (or gently rinse under running water.) Rinse the wick thoroughly. Put it back in the tray and humidifier with a full tank of water, and it’s good for another week, sometimes two. I check them weekly, for sure, and more often toward the end of 2 months. The tray needs to be cleaned at the same time. We have soft water, but it’s still pretty mineral-y, so everything gets crusty.Nothing is going to last forever, but with a little maintenance, cleaning costs a lot less than chucking a good wick every two weeks, or installing a whole-house humidifier. Plus, I can loan one out to the kids for college dorms. Some years I have more problem with mold than others, but cleaning is critical to spending less on wicks and putting a bit less load on the garbage chain. I also like the light “pool” smell I get for a day after a cleaning.Sad to see the prices skyrocketing in the last year (’23/’24.) Was hoping to see a drop, but all the more reason to clean them to keep replacement costs down.

Good replacement for existing filter.
Just Me –
Three for the price of 2! Awesome legit product
Mite Mite –
Although a little expensive, using the brand name wick is worth it. I get 3-4 months use out of one of these even with my hard water.
BEV –
A little more expensive but the quality is worth it

I like that fact that these filters are thicker than previous ones and and produce more moisture.
