Whirlpool Brand RO/DI Replacement Cartridges?

[cashmoney6980]

I was at my local Lowes store earlier killing some time, and walked down the water purifier aisle and seen a bunch of replacement cartridges for RO systems, and seen that Whirlpool has several reasonably priced cartridges, both sediment and carbon filters at sizes that would fit any aquarium made RODI setup. Are these usable for any system or are they meant for just household? They have from 0.5 micron to 30 micron. If they are usable, it would save me a few bucks in shipping and its right down the road from me

I am curious of the answer, but my guess would be yes.

The price on them was definately worth finding out. You can get two 0.5micron carbon filters for $11, and two 5 micron sediment filters for $6. And Whirlpool is a rather well known and trusted brand. So I hope for some positive answers
