Watts Premier RO recommendations?

Just joined the forum and have had an interesting time reading through some
of the posts!

I want to install a reverse osmosis system, as I'm tired of buying bottled
water from Costco and BJ's and lugging it home!

We have a private well as our source.

The Watts Premier reverse osmosis systems have caught my eye. I first
noticed them at Costco. At under $200, it seems like a nobrainer.

My question is: which model to get??? I'm confused!

I'm considering the WP-5 (Costco) and WP-4V (Costco) and TFM-5SV (Sams

I've been reading that a 5-stage system is the best, so that would seem to
point toward the WP-5 and TFM-5SV. However, the WP-4V 4-stage system
boasts that it removes Volatile Organic Chemicals from the water. I
haven't seen any other system mention this. Is this a gimmick?

Which 5-stage should I consider (WP-5 vs. TFM-5SV)? Anyone know the
differences, other than the WP-5 is about $30 bucks more? And, should I
consider the WP-4V? I sure don't think I want any chemicals in my water.
It's also the most expensive of the 3!

Thanks for any help and guidance guys!

3 stage, 4 stage, 5 stage. What is the answer. They will all do the same thing. Think about the stages. A 3 stage has 1 pre fliters and a membrane and a post filter, a 4 stage has 2 pre filter, a membrane then a post filter and a 5 stage 3 pre filters, a membrane and 2 post filters or 4 pre filters, a membrane and 1 post filter. The pre filter protects the membrane. To me, 5 stage is over kill. A 4 stage is close to over kill but necessary in some cases (well water). In your case, I would choose a 4 stage. The order of filtration should be sediment filter, carbon filter, membrane and post filter.

Carbon will remove voc's (Volatile Organic Chemicals). Just because it does not say on the box doesn't mean it won't remove it.
