Just got one that's a great deal. I have bought a refurbished unit before, I believe they come with a two-year warranty, awesome product.

I have had since 2022. It's an amazing product, paid 1k back then. It supplies two faucets, my fridge and my mopping vacuum.

Are filters expensive and need to be replaced frequently?

Very nice. Add a 3-5 gallon tank to this so it doesn't run every time you open the faucet and so you get that true 3:1 ratio.

Depends on your input water quality and volume of use.

The RO membrane has a "typical" replacement schedule of 2 years, and I think they're currently about $110 direct from Waterdrop. The other filters are about $30 each and have a recommended schedule of 6 months to 1-year.

So, YMMV regarding filter longevity, and the cost is going to be a little higher than a system with universal filters, but in my experience, Waterdrop also has great customer service.

Been trying to find info on this because the 1l flush seems excessive but I haven't been able to find anything. Do you have a link or something?
