SPT ION F-4010 Exchange Replacement Filter for SU-4010 Humidifier

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?

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 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.

This fits my SPT SU-4010 Ultrasonic Dual-Mist Warm/Cool Humidifier with Ion Exchange Filteras it supposed to, but lasts for only a couple weeks. Maybe this is all that is to be expected with Chicago water, but I'm constantly cleaning slime and deposits from the inside of the humidifier base and mist path, sometimes only a week after replacing with a new filter... However, I don't know of any alternative in terms of an ion exchange filter replacement.

I ordered this filter directly from Amazon. The filter I received is octagonal shaped, as shown above, but it replaced the round filter for my Sunpentown SU-4010 humidifier and works just fine.
