Query: As excited as I can be over a humidifer filter

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?
