The order was fulfilled quickly and shipping was expedited. The container was packed properly with no damage.The canisters are easy to install and are working very well. It was time for them to be changed & the water is has a purer and better taste.Thank you!

Purchased and installed a Brondell Circle RO system in August 2022.We're still using the original cartridges, I purchased a replacement set just in case and they are still sealed in the box.Changing them every 6 months is (probably) a waste of money.First, buy yourself a TDS meter (not a referral link, plenty of others on Amazon but this is the one I got- https://www.amazon.com/gp/product/B07QLZ6DT5 ) and test your water from the faucet versus out of the reverse osmosis filter. Our water is normally around 60 ppm, from the Brondell it is about 6-7 ppm.After a year it is still 6-7 ppm TDS. At exactly 6 months and again at 12 months the "change filter" light on the faucet started blinking. I don't think it is based on water usage, it is on a timer. All I do is remove the battery, wait 30 seconds and reinstall.Your mileage may vary, obviously our faucet water is naturally pretty low on contaminants (only reason we got the RO is that 2 of those contaminants are arsenic and manganese so it's nice to reduce those to safer levels) so if your tap water has more stuff in it your filters may get clogged up faster. But if you have a TDS meter showing you the filter is doing its job AND your water flow is not slowing down changing the cartridges is unnecessary.Hope that helps someone concerned about the high cost of these oem filters.

We purchased the device from Costco and buy these on Amazon. Water is delish and clean. I have a TDS meter. My tap water measures 149, the Brondell RF-20 Water Filter it measures 22. You want it in this range. I use to use 0 water and yes it measures 0, but it also neutralizes all the important minerals and trace minerals that our body needs.

I love my water filter. I always have great tasting and safe water. Although, these refills are not cheap, they are worth it. They are cheaper than water bottles. My last filers lasted 2 years so they are well worth it. They a re also very easy to install. I will be purchasing these again!

We purchased the machine from Costco then found out that this filter is a bit expensive. It’s easy to install and last over a year. We might switch to cheaper machine after a few years but at this moment this filter system works.

Order this filter every 6 months.

Works well. Easy replacements. Same price as company website

Easy to install, but I don’t know if it’s useful or not 😆
