What's the difference between 100 and 300 Crs? Is it the amount of water it can pass through before needing to replace the filters?

That is correct. Specifically I think the model number denotes the gallons of water it can filter before you replace the resin.

I read the spec on the ratio between purified water and drain water but can't recall the numbers. The amount of water used in the process isn't something I notice but if you are concerned about this compare the ratios between purifiers to get a baseline. My purifier continues to provide trouble free service. Very satisfied.

If all the filters are original PUR* replacement filters, the filter medium will be the same. Someone has posted that the PBSS filter is inferior to the others, but I see no data to back up that assertion. The difference is in the amount of water they can filter before recommended replacement and the flow rate. The "universal" PBSS filter is rated at 100gal. capacity and 0.5GPM flow rate. The 4396710 is rated 200gal. capacity and 0.5GPM flow rate. The 4396841 is rated 200gal. capacity and 0.85GPH flow rate. Strangely, both the 100 & 200 gal. capacity models are recommended for 6 months replacement. You would think the 200gal. models would last longer. Some whirlpool refrigerators offer what's called "fast-fill" systems, which dispense the water almost twice as fast as "normal" systems. It stands to reason that the 4396841 would be best if you want/need the higher flow rate. It also stands to reason that the lower flow rate models probably filter better since the cartridges (and presumably the filter mediums) are exactly the same size (educated opinion). I have decided on the 4396710 for my refrigerator. I researched a lot for this answer, I hope it helps.

My last filter went 198 gallons then blew up. However, I think it is our water quality and the age of the system. The first one I used worked for the whole lifr as expected.

From what I know these filters are fairly standard in terms of filtration area. I've used several brands and this one is the same as the others and I also have a hayward filtration system.

It depends on your water source and its quality,if you use this residentially or commercially,but I would get a TDS meter(cheap here) and this gives you an idea of incoming water vs your RO system has purified,you can google TDS values and get a idea of good and bad.In my situation my incoming water is around 160ppm and my RO system water is around 7 ppm.You need to do a quick and easy calculation(google it) of your situation,and this will tell you the performance of the membrane and its efficiency.I typically get at least 3 years to a membrane,but check mine often,with my TDS meter. I know this is long winded but every situation is different,it's really very simple once you get the TDS meter,thus being much more accurate,also the membranes are rated for efficiency,so make sure you get one that works for you. thanks,good luck

NO. only a difference of 300 PSI. and .2 Gallons per minute. You would not notice a difference at all. Buy the one for $100 less in my opinion. Ive had both in the past. NOT worth the difference. Hope this helped.

As far as I now there is no difference. I have changed mine for different water levels a couple of times. paid no attention to which is which, and everything always worked.

The system is about as low tech as it can get ant there doesn't seem to be a reason for any dramatic change. I've been using it for about 30 years and the only change is the addition of a handle. My guess is, the only difference is the 2 extra filters.

I have them both. The 300 is a bit quieter, however, it requires filter replacements much more often (3-5 year vs 1 year). Therefore, which is more important to you?

I beleive this filter uses standard sizes that you can find at most hardware stores. (IE. same filters you fuse for some of the more standard filters in the store). Filter performs better than expected. I use for gardening, fish, as well as for drinking water. Best price for a 4 stage 100 gal an hour filter that comes ready to install and I highly recommend for anyone intending to use for aquarium/ gardening. If used mostly for drinking water I might get something with a tank to install under the sink.

As far as I can tell the difference is only in the price. Both filters work equally well with the Franke Triflow faucet system for the kitchen.

Both are rated for the same particulate filtration (0.2 microns?) and claim to filter the same amount of water (up to 13k gallons if I remember correctly). I have had my hands on both and I can say I'm glad I purchased the combi. The down side is the warranty is not as long. Oh and the combi has held up well in a pack, use on the trail, or camping.

Its the type of replaceable filter media that comes with it. The 3 stage cost far less due to removing less contaminants compare to 10 stage filtering. IMO: The 3 stage is far better then the most refrigerator water filter most people use and if you are using municipality water source, the water is safe to drink anyways and the 3 stage filtering is sufficient. 10 stage is nice insurance but I choose to save the money........Hope that helps.

The 204 parts are smaller the impeller /shaft and cover are totally different/way smaller/the 304,305,404 and 405.parts are the same,except the handles and outer parts and canisters,where you can clearly see a difference. Fluval the best filter out there.(I have four running quietly as we chat) Go get em Mike

The EQ-300 is a filtration system, designed for reduction of chlorine, chlorine by-products, and other synthetic materials/chemicals. It is not designed for changing the mineral content of the water at all. You are actually looking for our salt free water softener, the EQ-AST-WH.

I'm pretty sure it was 100. Also easy to cut your own from standard filters.
