About this item
- ANNUAL FILTER REPLACEMENT KIT: Say goodbye to unpleasant tastes and odors with the Watts Premier Annual 7-Pack Standard Water Filter Replacement Kit, a one-year supply of 3 types of filters that are tailored for specific filtration purposes, collectively ensuring crystal clear, great-tasting drinking water every time.
- HIGHLY EFFECTIVE FILTRATION: This kit includes two 5-Micron Sediment Filters (WP104017) for reducing dirt, silt, and rust that affects the taste and appearance of your water; four 5-Micron Activated Carbon Pre-Filters (WP101009) for conditioning the water and reducing chlorine tastes and odors; one 10" GAC (Granular Activated Carbon) Inline Post-Filter (WP100014) for removing chemicals that give objectionable odors or tastes to water, such as hydrogen sulfide or chlorine.
- VERSATILE COMPATIBILITY: These filters are designed for specific use with Watts Premier's 5-stage (WP500032) and 6-stage (WP521934) Reverse Osmosis Systems but are also conveniently compatible with any standard 10" filter housing for under sink home filtration systems.
- QUALITY CONSTRUCTION: These durable filters are crafted from high-quality materials for maximum filtration, with the carbon filters constructed from NSF certified coconut shell activated carbon. Filter life may vary based upon local water conditions or use patterns, but we recommend replacing sediment and carbon pre-filters every 6 months and the GAC post-filter once a year.
- THE PREMIER DIFFERENCE: Since our founding in 1989, Premier has been dedicated to the design, development, and marketing of high-quality water filtration systems that exceed industry standards. Following our Watts Water Technologies in 2001, our audience and influence have only expanded, solidifying Watts Premier as a trusted leader in the industry.

High-Quality and Affordable Filters
Jaime—August 14, 2024✓ Verified purchase
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. Read more

Amazing value!
Surfer Ed—December 13, 2010✓ Verified purchase
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... Read more

Great tasting water
B. Sisler—February 16, 2023✓ Verified purchase
I buy these for my Watts Ultra 5 reverse osmosis system. They are OEM filters and fit perfectly. The water tastes great. It is basically distilled water as long as you test the total dissolved solids periodically and replace the membrane if needed. We use the water to make tea and coffee and also to fill the water tanks on our CPAP machines. I gave it 3 stars for ease of installation because the system is under a sink and it's a little hard to get to. Your installation may be easier. Read more
