HoneywellReplacement Wicking Filter A, 3 pack, White, 3 Count

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.

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.

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.

Good product but you need to rinse and turn over everyday to ensure it will last about two weeks

I only buy the manufacture brand and not the cheaper imitation brands because my experience proves that these last longer than the aftermarket brands I tried in the past.

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

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!

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.
