15 Best Selling Reverse Osmosis System For Hydroponics

Buying Guide

The purpose of this buying guide is to give you the items that you would need to consider when choosing the right filtration system. 

1. Storage

The storage is area should always be the first item that you would consider when looking for a filtration system. Although modern reverse osmosis systems do not take up much space and can easily fit below your sink, it would still make sense if you check it out before purchasing. 

If you cannot fit a filter under your sink, then a portable tabletop filter is for you. Just ensure that you can route the supply easily. 

2. Water Pressure of Raw Supply

All reverse osmosis filtration systems do not function properly if the water supply is below 40 psi. If your home’s water supply does not have the required pressure, then you can purchase a water booster pump to increase the pressure. 

3. Replacement Filters

Like any other filtration system, the filters themselves have a lifespan and must be replaced based on their specifications. Take note the RO system has more than one filter that you would need to maintain. 

Although there are contractors who can do the maintenance for you, it is more efficient if you can manage to do it yourself. Find systems that can easily be maintained. Modern-day portable systems already feature this technology.

Here are the 15 best Water Filters and RO Filtration Systems For Hydroponics:
