Watts Premier Annual 7-Pack Standard Water Filter Replacement Kit for RO-TFM-5SV, WP-ST6DM, WP-5, WP5-50 Reverse Osmosis System, 2 Sediment Filters, 4 Carbon Pre-Filters, GAC Inline Post-Filter

I recently purchased the Watts Premier WP500024 Standard Annual Water Filter Replacement Kit, and it has been a perfect match for my Olympia RO water filtration system. The filters are of excellent quality, and the kit is well-priced, making it a great value. I appreciate how easy it is to replace the filters every six months, ensuring my water remains clean and fresh. Overall, I'm very satisfied with this purchase and highly recommend it for anyone looking to maintain their RO system efficiently.

Works fine.

I'm amazed at what you get in the package. Added up individually, these items would cost almost $60.00! I have had an RO system for over 7 years and this is the best deal for replacement filters that I have found anywhere. As another reviewer stated, not even the Watts website has prices this low for these items. That's the good part. The not so good is two things: One is that both of the sediment filters were slightly dented upon arrival. No big deal though, and that won't affect their functionality. Another slight problem is that the post carbon filter doesn't have the 1/4" quick connect fittings that my 4 stage RO system setup has. No big deal, as another reviewer suggested, I went to the hardware store and bought two adapters to add to the filter- don't forget to use teflon tape! These adapters convert threaded fittings to quick connect and cost six dollars for both and can be removed from the filter later to be reused again on the new post carbon filter.After installing the new filters I tasted the water and I can't tell if it's different from the old filters I was using. It does taste good though, like before.I'm rating this product 5 stars for the great deal. I would take away one star for the packing of the product prior to shipping, but this is too good of a deal and is worth the risk of some damage in shipping.Update: Sept. 2011: The filters are still doing great and I'm still super happy with this purchase. I just hope this deal lasts...

This is my second time ordering this item, last time was 12 years ago. These are OEM replacement filters for my reverse osmosis system.

I’ve installed the Watts RO filters for decades For my family friends and every time we move . So, I have changed lots of filter elements.I believe the Watts filters are the best available, Especially the carbon filters. I’m very technical and have specified many filters for the Chemical industry. I look at the difference between activated carbon, carbon block, Carbon granules and like . Carbon block are the best for use with the RO element. Activated carbon is best for the polishing filter, i.e. The last one before the water tap.Different types of carbon can remove different toxins & poisons, and some remove different micron size particles. Some have the capacity for use as RO elements and others are for full flow like we use in our Veggie sink. The smaller micron elements take a higher pressure drop, thus lower flow. Be careful if you don’t buy filter elements especially made for the reverse osmosis unit. No worries with this Watts selection.I was happy to see this double pack come on the market. Having spare elements is handy, and it reminds me when it’s time to change them . I don’t procrastinate to order new ones when I have a back up set available. This also allows me to wait for a sale.Watts replacements are a bit more expensive than others available. However I don’t mind paying a little more for a consistently higher quality product. Don’t be fooled just by price.One area of concern which led to four star instead of five star. Watts makes a bunch of different models. They use different types of carbon in different RO units. I don’t know why they do this. Since the largest size carbon filter element can fit different models, I will use of the carbon block if a different carbon type is specified by Watts. Their technical department has told me that this is acceptable and I Have not run into any problems to date .

I ordered these to replace the filters on my RO system. These fit perfectly. Looks identical to the original.
