Replacement Filters

Good performance and reasonable price over the years.

They fit Perfectly !!! Good buy for you money

Great price. I have ordered this filter pack 7 times and I never had any problems. It is delivered and arrived promptly to my home. Changing filter is fairly simple. Water taste good with no added taste like regular tap water.

I have bought these water filters many times. They just never disappoint. They fit perfectly into the housing. They are compatible with my 5 stage RO filter. They have gotten cheaper over the years, maybe due to manufacturing efficiency. I will continue to get these whenever I need new filters again.

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 .

worked as it should

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...

Me gusta mucho. Con estos filtros no tengo que comprar agua en botellas o garrafones. Lo he usado por años. Dejan el agua muy limpia

With this price, this is likely the best options that I can find. It is very easy to install, I just take off the existing one and I know which one is for which. BTW, it is probably worth to look for "change ro filter" videos on YouTube first. I found a 5 mins video and it is very helpful. In general, like this product.

These filters are a great alternative for the brand name ones and a great price.

Well made filters works fine in my watts set up

Nothing to complain about these filters, nice value. But don't forget to buy that RO housing wrench, or one day, what could've been a relatively simple procedure, might turn into a hand injuring nightmare.
