RO SYSTEM what’s best small grower !!?

[trixP]

Was looking at those small countertop RO systems on Amazon, any units or systems superior than others ???

I love to portability of the countertop systems also that I live in an apartment, however I’m wondering how long it will take to fill a reservoir for my 2-4 plants

Thanks

I have this one and I'm very happy with it.

my tap water is usually around 160-220 ppm and this gets it down to 4-6 ppm. takes about 16 minutes per gallon iirc.

they also have a 50 GPD model

I’m looking at the express water unit, I like how it had a on off valve at the faucet, curious to know what the avg system takes to fill

I would say most small RO systems will give you around 1 Gallon every 15 mins. I get that with a Hydrologic
StealthRO

Thank you for this. Is there any difference between the 3 stage and 4 stage filtration models?
