Delivered on time and properly package to protect. Great filter and easy install.

use in room humidifier. quick delivery. exact replacement.

I have lived in Chicago for many years, then moved to Colorado 28 yrs. ago. Went from humidity to ZERO humidity. Lots of sinus and resp. problems from the dryness. Ran humidifiers here but too much white dust if ultrasonic. I tried the distilled water which was great and cut down on the dust, but it was really expensive even at $1/bottle if you are using it 4 times a day etc. So bought this filter and I can use tap water right from the sink and no white dust. GREAT!! Our water is so hard here, the humidifiers are put to the test. But I am happy with this. I also use those small mineral balls you throw inside the tank to keep the algae and mold from forming. Every morning, after running all night, I open everything up, air dry it and let it sit open till night time for more humidity. Then clean everything once a week at least with antibacterial soap and weak bleach.

Just mentioning that I uploaded a picture showing the actual shape of the filter I received, which differs from the shape shown in the default product image. The filter is actually round, which matches the shape of the original filter that came with this humidifier. I don't know if the hexagonal filter currently shown for this product will fit in this unit, but I have my doubts considering the filter on this model is designed to fit inside the tank and the opening in the tank is also round... but it seems the discrepancy might be moot if all others who purchased this filter also received round filters.BTW, I gave it 4 of 5 stars only because, although I feel the humidifier works as I expect it to, I feel it's over-priced and I'd much prefer that the filter be redesigned to reduce waste, perhaps by making the plastic casing reusable.

I'm not trying to be lame, but this is a replacement filter (the exact type that came with the SU-4010) -- I cannot really get too excited over a water filter. I have no measurement equipment to even know if filters make a difference, but I'm going to assume they do. This fits and works perfectly with the SU-4010, which if you want an awesomely awesome humidifier I don't think you could do better. The SU-4010 is essentially silent and easily gets even larger rooms up to 80+% humidiy if needed. I have extreme excema, I keep the unit on 24/7 on its lowest output setting -- keeps the room or rooms at about 65-70% humidity and it has no problem keeping up. Go buy the SU-4010, then order a few of these filter to have on hand. I do think they should have them in different colours...then I might be more excited by their arrival. Neon purple anyone?

This comes with the humidifier that many of you know is a pain in the but, but the best and most reliable cool/hot mist makers out there....that's right, the SUP!!! lol! Its okay, this filter unit, IF u NEED IONIC EXCHANGE TO REMOVE CALCIUM, LYME, MAG, ETC from water....if you use RO, I would still consider the salt corrosive to any Ultrasonic Unit....OH, and REMEMBER THIS!!...DO NOT USE SILVER NITRATE PURIFIERS, such as the very popular baby blue rattles....that is Silver Nitrate... and it DESTROYS ULTRASONIC UNITS OF ALL KINDS, DO NOT USE IT IN WATER THAT IS RUNNING THROUGH AN ULTRASONIC UNIT!!!!! I lost 3 units before I figured that out!!! :( But thankfully they always honor the order, and I just set the filter aside in the sun to dry, waiting for a day when I need it. Otherwise, it would be 3.5 stars! lol! Enjoy!

I took one star off for the price. Otherwise, these filters help keep our hard water problems from keeping our bedroom humidified (which the ‘system’ does do well). Based on our usage, we replace these every 30-45 days in high season (we live in NYC).

This filter does a poor job of reducing/eliminating white dust. We bought the F-4010 a little over a year ago, and while it's a very good humidifier we were disappointed with the amount of white dust resulting from its use. I had hoped a brand new filter would make a difference, but it did not.We were considering a switch to distilled water, but that's pretty pricey. Then we hit upon another solution that has worked really well--a Brita pitcher. The Brita filtration has pretty much eliminated the white dust.The pitcher itself runs about $20, depending on the pitcher you choose, and includes one filter that will last between one and two months, depending on the humidifier setting. After that, a three-pack of filters costs $15 on Amazon.A three-pack of filters will last us an entire winter for an annual cost of $15. A new filter every year is almost twice that and is far less effective.

As described and came in on time. While the filters are in my opinion very expensive, they do last a long time and am able to replace them about once a year. Very important to run with the filters in as it keeps the humidifier working clean, silent and increases the life of your unit.
