Ok...so I''m not the person that''s concerned about taste. In fact...most of you reading this don''t care about why Reverse osmosis filtering is important for an aquarium....but let me begin on the basics.1. Yes it wastes somewhere between 4-5 gallons for every 1 gallon it filters.
2. It does take up under the sink space...if your not at all good with plumbing and don''t hire a professional.
3. The filters run about 100$ for a full set 1 pre-filter, 1 post-filter, and 1 Reverse Osmosis filter.
Note: they say you will need to replace every 6 months...If you have hard water and can smell it from the tap, you will likely have to change the filter more often. If you have relatively good clean water the filter could last a year.
4. WHY I USE IT: The option of getting a Reverse Osmosis unit not only softens the water, but removes 99.5% of the bad chemicals in your tap. Chlorine, Chloramine, Flouride...etc. I have special fish that need clean soft water this is the best way to get it.
Now I tried the Home Depot GE version (same price) and let me tell you....it was the shoddiest, cheap, and in the end worthless unit. I took it back after the tank nut cracked while it was pressurizing...only to find out it was also missing a 2 important seals. I returned it and headed to Lowes...
Whirlpool Reverse Osmosis Filtration System WHER25
Pros :
Easy to install (if your not too concerned about how it looks)
Highest quality parts than any other competitors in the same price range.
Fairly quiet
Saves money in the long run (for me it paid for itself in a month...but then I use it for large aquariums)
Cons :
If your not handy putting things together, you''ll need a plumber but you can then have all the equipment setup in your basement or garage out of the way.
It does waste 4-5 gallons per 1 gallon of drinking water, but once it fills up the attached tank it stops the process.
If you absolutely need to get an RO unit at a budget price, this is the unit you want to buy. I never considered ''whirlpool'' a quality product over ''GE'', but this is one very large exception to that rule. If you have a larger budget, you might consider some of the large setups they are more efficient over time and a bit more convenient if you need more that 2.5 gallons at a time.
Have had mine for 5 years and only changed membrane once. I''m connected to city water and move the post filter to the pre spot and put on a new post filter about every 6 months or so. The pre filter needs to remove big items, the RO membrane removes the disolved solids and the post filter removes the odor. If you have lots of smell to your water, like with some wells, might make sense to change both every time.

With all the negative reviews, I thought I better add my own to balance it a bit.I installed it my self. Took me a couple hours but had no real problems. I did have to press in one of the hoses that I did not have seated properly, but that is my fault. It''s been about a week and no leaks.
I had the water tested and my normal tap water has 1200ppm TDS, and after the RO, I got 320ppm TDS. Which isn''t great, but it should be safe. I''m going to add another charcol filter in front of the system to try and knock down the TDS some more. Also our local water specialist is coming this week to service our system in the garage. I suspect after they are done, our TDS will be down to a level this RO filter can handle better, I may not need the charcol filter.
We have a Well, so high water usage isn''t so important to me. It goes right back down the drain and back into the ground where it came from. City Water users might be concerned about the water usage. It''s cheap, easy, and works and I chose this because of the twist in/out filters. No more spilling water all over while changing filters.

What I like:1. It delivers good, bottled quality water
What I don''t like:
1. High cost of replacement filters
2. Cheap, fragile plastic connectors
3. Not easy to install; may require modification of existing water supply and drain piping. Will probably require extra hardware for proper installation.
4. Wastes too much water
My uses for this product:
Ice making
Coffee & Tea beverages
Drinking water
I purchased this product for under-the-kitchen sink installation. I wanted a RO (Reverse-Osmosis) filtration system to remove hardness constituents from the water for our coffee maker & ice maker.
Installation was somewhat difficult; I had to purchase another shut-off valve that was suitable for my 3/8" copper plumbing, a 3/8" to 1/4" tee adapter to connect the enclosed water supply tubing to the RO unit, and another 1 1/2" drain adapter (enclosed adapter was too short) to accommodate the RO drainage into the kitchen sink drains.
This product came with a charge tank, chrome plated drinking spigot, CR2032 battery, 1/2" plastic threaded tee connector for the water supply, a drain adapter for under the sink installation, a drain connector (which I was able to use) a plastic water connector for the tank, plastic color-coded hoses, some teflon tape and a plastic sanitizing pipet.
You must follow the instructions carefully to properly install & hook up the RO unit and avoid leaks that many reviewers have experienced.
It took about 24 hours after installation, sanitizing & charging the system before it was fully operational. I estimate the unit drains away approximately 3 gallons of water for every gallon of filtered water produced.
However, the unit produces very good tasting water that leaves very little behind in the way of calcium scale deposits. I have found that I can just replace the pre and post water filters only without replacing the reverse osmosis filter cartridge every 6 months. The original reverse osmosis cartridge had lasted nearly 24 months before I replaced it.
I would have rated this as 5 stars if the unit didn''t waste so much water. I recommend it.

Pros of this unit:* fairly easy to install
* filters are easy to change
* neat and clean
Cons of this unit:
* filters are very expensive (almost $100 for the full set)
* you have to change filters much more often than 6 months if your water isn''t good quality to begin with
* it wastes a lot of water during the filtering process
* it''s noisy during the filtering process
We got this system about 2 years ago from Lowe''s and installed it ourselves. It functions properly (we never had problem with leaks, etc). The first few months we were very pleased with the product, but around about month 3, we started noticing that it began to run constantly, even all through the night. It''s quite noisy as well (it makes a gurgling noise during filtering). Upon calling the Whirlpool customer service, they said this indicated a need for filter change. Sure enough, once we changed the pre-and post-filters, the problem resolved. However, we are regularly needing to change the filters every 2 months now. We already have a water softener installed, so I''m not sure what else we can do to pre-condition our water, which is what Whirlpool wants you to do when you call their customer service. Isn''t that the purpose of this unit? Paying $50 every other month for filters on top of our monthly water bill is getting old. Unfortunately, I think we will be uninstalling it soon and just buy bottled water.
