Thomas, Your are correct. The NS Research filter is not much more money than the L-Factor in initial outlay. But.... Better quality air? How good do you want it? Both filters give you hyper-pure air both O2 blending. The NS research has 3 filters to replace each of which is nearly the cost of the single L-Factor filter. Since the filters need to be replaced once a year anyway, well you do the math.... I'd rather replace 1 filter than three. The L-Factor filter is similar to the older L-Factor filters that were put out by Underwater Applications, but in this case they have stacked two elements one on top of the other. The way I look at it, do you want to replace one filter or three? Keep in mind I'm talking personal use here. If your running a business with these, then you might actually make use of the additional capacity of the NS research model.
