Global Water RO-505 5-Stage Reverse Osmosis System Water Quality Filter

While researching water filter systems, the Global Water RO-505 5-Stage Reverse Osmosis System Water Quality Filter stands out with its ability to provide healthy, clean, fresh, great-tasting purified water at quite a reasonable price.

Coming packed in a ready-to-go kit with many inclusions, Global Water Solutions have gone above and beyond in order to make the installation of this system as simple as possible.

Being one of the most affordable reverse osmosis systems, you would think that maybe they didn’t put as much into the installation kit as they could have. But, in fact, they give you double the filters (two-years’ worth) and so much more as you’ll see as we unpack it here.

This is also an extremely thorough water purification system.

With five filters in total, and one of them being the reverse osmosis membrane, the Global Water RO-505 can provide you with up to 50 gallons of purified water each and every day.

A full year of life will see you replacing the filters at a usage life of around 18,250 gallons.

That’s decent!

This isn’t the system for you if you’re looking to filter your whole house or something like that. It comes with its own faucet that is secured to your countertop and is specifically designed for just drinking water or to be connected to your fridge for the same purpose.

So, for high-quality drinking water, this system is going to be worth investing a little time into and finding out if it has all the bells and whistles that you’re looking for.


Features You’ll Value

Assembled and ready for simpler installation

They call it, “pre-installed” and it is!

The unit is tucked tight together and ready to be fixed into place. Make sure you’ve got plenty of room for the storage tank and the filter bodies. Removal of the middle shelf under the sink is usually a good idea and makes the job a lot easier.

The five filters are secured together quite well. With 3 large canisters across sitting vertically and two lying horizontally on top of those. I think this makes the best use of space under the circumstances.

For the connections that you do need to make they’ve color-coded the tubing and utilized quick-connect fittings to make it so much easier.

If you need to install it in an adjoining cupboard for space reasons or whatever, you can easily purchase extra tubing and/or fittings to go that little further.

Not to mention that lifetime 24-hour technical support is offered from Global Water in USA, CA for purchasers of the system.


99% Contaminant removal

When you don’t want anything in your water except for the water itself, you turn to a reverse osmosis system and this one is no exception.

With the ability to remove up to 99% of all contaminants, it’ll bring you better than bottled water purification and directly into your kitchen.

Chlorine, lead, bacteria, arsenic, fluoride, particles, sand, silt, heavy metal, salt, bad mineral substance, and other dissolved chemicals are all taken care of with the Global Water RO-505.


Long-lasting filters

Global Water Solutions, the manufacturer of this filtration system, advises that the filters should be changed on a 6-12 monthly basis. Although, some purchasers have found that the filters are just starting to seem like they should be replaced after 2-years!

Either way, these high-quality filters can stand their ground for quite a while and keep even the toughest of water-snobs happy.

An additional set of filters on top of the ones already fitted to the unit are included at no extra cost.

This is one of the many benefits of having multiple filters set up and running alongside each other, they protect each other. Each one catches something more which prevents it from going any further down the line, which not only provides you with great tasting water but makes the next filters last much longer as well.


Well-built quality

Each of the filter housings has double ‘O’ rings making it super-secure from leaks around these seals.

The faucet is 100% lead-free and complies with all the necessary standards for modern design as does the metal storage tank.

As mentioned, it uses quick-connect fittings and also has a built-in automatic shut off valve making filter changing easy.

The Global Water RO-505 5-Stage Reverse Osmosis System Water Quality Filter may well be one for the shopping list, I think.

There’s so much to consider when purchasing a unit like this and there is a lot of competition in the market. But, thankfully, if the end goal you’re reaching for is water purification, safe to say we’ve checked that box off.

Not to mention the fact that it comes with that second set of filters which should keep you going well into the second year of its life.

Overall, this is a sturdy unit. No bigger than most in its class, coming in at 14 x 5 x 16 inches and ready for any under-counter installation.

Just make sure you’ve either got the space for it (remove the middle shelf) or purchase some extra tubing to run it a little further along to where it’s not an issue.

You’ll love the convenience of having a dedicated purified water faucet on your countertop right near your sink (or wherever you choose to put it) and will save countless dollars from not having to go to the shop and buy any more plastic bottles.

The environment is already thanking you!
