 Excellent Dust Contol November 10, 2008
I live on a dirt road in the desert southwest. Before purchasing this device we would need to dust our living area at least weekly or face significiant dust build up. After 4 weeks of operation we have yet to find ANY dust build up in a 250 sq foot living room, nor any significant dust build up in the adjoining dining room and kitchen.
Device is very quiet. We generally never notice it running. It will kick into a higher speed when we sit down on the sofa and generate dust, however it is a very soft fan noise and not at all disturbing. We like this unit a lot.
 Excellent filter, no dust sensor October 2, 2008

The filter is exceptionally quiet and very well made. Plasmacluster could be the best active cleaning technology available. I happen to own a model with humidifying function KC-C150U and the FPP60CX. The FPP60CX has a much better charcoal filter and is quieter, however the FPP60CX does not have the dust sensor in KC-C150U, which works very well. The sensor in FPP60CX does not seem to work that well - it is almost always green and does not detect the changes in the air that KC-C-150U does. The KC-C150U on the other hand has inferior charcoal filter, is noisier and its humidifying method is vulnerable to bacterial growth. The previous Sharp model FPN60 seemed to be better because it had a good dual sensor.
good quality and space saving May 14, 2008

I was influenced by the 1st excellent review because I debated between this model and Rabbit Air too myself.
Ever since I moved from Brooklyn to Manhattan, I started having breathing problems during sleep time. This filter has helped my breathing and reduced my asthma significantly. I can also set the timer to auto shutdown after 4 or 8 hours before I leave for work every morning and come back to a fresh smelling apartment (building next door is a pizza parlor).
From aesthetic point of view, I think Sharp has a nicer look. It's slightly smaller and thinner, which is great for my small studio. The white plastic casing is flimsy looking though. Rabbit Air looks a lot more expensive and modern.
If only looking at technical criterias, I think both models are at par. Overall though, this model is perfect for a busy person living in a tight space.
Great improvement in nightime allergies. March 11, 2008

I was trying to decide between Sharp FP-60CX and the Rabbit Air BioGS 421A, which are about the same price. I ultimately went with the Sharp unit because I wanted to operate the unit without a remote (the last thing I want is another remote!), the lights can be turned off, it has a higher CADR rating and is Energy Star compliant. FP-60CX features I like:
- remote is not essential
- the display light can be turned off
- gently kicks into higher gear when dogs leap on the bed!
- adjustable louvers to steer output air
- remote uses AA batteries
- washable pre-filter
- higher CFM/Watt in silent mode: Sharp= 31/4=7.75 versus Rabbit= 39/7=5.57.
- Max CFM rating is 233, which is substantially larger than the Rabbit 421A's 159. Note that the Rabbit is marketed as a 600 sq ft unit, but if you use the same CADR multiplier as the FP-60CX (1.42) it would only yield 225 sq ft. To put it another way... the Sharp unit would yield 879 sq ft (i.e. 600*233/159) if Rabbit marketing numbers are used.
I used to have a Honeywell 50250 in the bedroom, but I still had nighttime allergies and wanted to try something different and quieter. I find the Sharp unit in MAX mode is quieter than the 50250 on "silent" mode. I was also pleasantly surprised to find that my nighttime allergy symptoms improved dramatically with the Sharp unit. Both have equivalent CADR so the improvement may stem from the fact that because this unit is so quiet I can keep it next to my bed and it won't disturb my sleep.
