CF filter
Why does the filtered water taste funny?
1) The filter is about to expire. Check the indicator reminder to confirm and replace it.
2) The system hasn't been used for a while. Turn on the RO faucet and allow it to flush for a while before drinking.
What will happen if I do not change my filter when the filter life indicator light turns red?
Over-used filters will degrade the filtration performance, causing contaminants to leak back into the water and adversely affect your health. It's recommended that you replace the filter if the filter life indicator light turns red.
Why is the filter life indicator light still red after I changed the filter?
You have not reset the filter life indicator. Please reset it: Press and hold the CF filter life indicator for 7 seconds, until the system beeps and the blue light stays on.

Purchase two at a time.

The best RO we've ever had! However, I think the company is having a hard time keeping up with filter demand. I suggest purchasing an extra CF, CB and RO filter to have one of each on hand. Your supposed to replace the filters within a week of the light turning orange on the spigot. At the time of this review, it is taking Waterdrop 3-5 weeks to get replacements. Back to bottled water for a while.

I love waterdrop filtered water

I have been using waterdrop for over 1.5 yr. The taste of the water and the convenience of seeing when a filter needs to be changed. The filter is very easy to install, no need to remove any other components. Just twist and remove this filter from the front of the unit and replace with new filter by twisting it back in the locked position. Its so easy

filter works great but plan far ahead

Heads up that I reviewed the unit itself noting to stay away. Since then, the company has reached out to me and made sure I received the CF filters. They did that, though, when the timeline here indicated a wait of 3-5 weeks(!). I super appreciate the customer service, but felt that it wasn't overly fair to those waiting with a beeping unit.PLAN AHEAD. Set a calendar reminder at 4 months to purchase the CF filter so you can accommodate any stock issues. Typically, I'm seeing 3-5 weeks for the wait for a CF filter. Rarely, I see a week or actually in stock.The filters are super easy to replace. Do note if you have issues with reduced water flow after replacement to reach out to the company and let them know. There is something they can do to help with that. Our issue was resolved within a week.
