With a capacity of 100gpd, this unit is perfect for various applications, ensuring you have access to the cleanest water possible. ## Description The Finest-Filters 4 stage RO unit with booster pump is ideal for ultra pure water production in a range of applications, and especially in situations where the water pressure is too low for effective water production rate from an un-pumped system. This is a very advanced RO unit, with a built in booster pump, automatic membrane back flush, pressure gauge, high pressure and low pressure switch. The built in booster pump ensures the optimal water pressure is supplied into the RO unit for the best rejection rate and water production speed, saving both time and water. The automatic flush unit will operate periodically and back flush the RO membrane. This will prolong the life of the filters, and eliminates the need to manually back flush the membrane. The built in pressure gauge displays the water pressure (psi) to give piece of mind that the RO unit is working at the optimal water pressure. This unit is available in three different sizes (50gpd, 75gpd and 100gpd). gpd = gallons of product water (approx) produced per day. Please select the required model from the drop down box above when ordering. The physical size of the units is the same, just the membranes are rated at different capacities. These 4 stage units have a DI chamber, which is supplied filled with high quality DI Resin. After passing through the membrane, the filtered water is passed through the DI resin, to reduce the Total Dissolved Solids to 0. This is a 4 stage RO unit, which will produce 0 TDS water. Please note: The booster pump fitted to the unit is not rated for continuous use. The pump can run for a maximum of 2 hours then would need to rest for 15 to 30 mins. If you need to run the unit for long periods it is best to use a plug-in timer to turn the pump on and off as required. If you require further information regarding this, please contact us. ## Features - The Finest-Filters 4 stage RO unit with booster pump is ideal for ultra pure water production in a range of applications, and especially in situations where the water pressure is too low for effective water production rate from an un-pumped system.

I think placement of the solenoid is in the wrong as it does mean that when you first turn it on the pump will be running dry whilst the second pre-filter fills up. **Q: hi can i use this r o unit for marine aquarium the 4 stage or do i need to add xtra filter please** A: Yes you can, i also have a marine aquarium which was my main reason for purchasing this, it works great and produces 0 tds water, i also brought a inline tds meter to go with it and it is producing better quality water than i was buying from my local fish shop, you can always add an extra stage later if you really wanted to, but at the moment 4 stage is just perfect, would recommend a inline TDS meter to monitor when filters need changing though **Q: can this be left outdoors when running?** A: The instructions have a caution do not use the equipment outdoors and do not place in direct sunlight. I run my unit under a sink waste pipe from the unit into the sink waste. The unit works great and the Finest Filters company will answer all enquiries. Hope this helps you. **Q: Does the pump turn off automatically when water is turned off?** A: No, it will continue running. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works as it should *by C***R on Reviewed in the United Kingdom on 16 March 2024* I think 100g/d is slightly exaggerated.Took me hour and half to collect 25 l of pure 0 TDS water.It's perfect for marine tank ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Very easy to install *by M***N on Reviewed in the United Kingdom on 15 December 2023* I saw a lot of other reviews stating these have bad instructions and are difficult to set up.It's as simple as, open each chamber, remove the plastic wrap and reinstall then tighten up. Same deal with the Membrane.Had it up and running in about 10mins and so far has made me a very clean 25L of 0TDS water for my Aquarium.One thing to note is the piping and routing of said pipes may need fiddled around/sponges put it if you have it somewhere where ratting is an issue. Mine had a single connector that rattled off the bracket with the resonance of the pump. Tiny bit of sponge in the right place stopped that.Fit nicely under my sink.Can't vouch for customer service/aftersales as I've not needed to use it yet! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Perfect compact RODI unit *by R***S on Reviewed in the United Kingdom on 7 May 2020* You cant get better for the price. I needed RODI for my marine tank quickly during lockdown and this was delivered quickly. Produced around 25ltr in around 30-40 minutes. Its quiet and easy to use. The building purge controls and pump are brilliant. Makes life really easy. I did buy an additional TDS meter so i know when the resin or filter are done.Setting up was a bit of a challenge though as it did not come with instructions so only gets 4 stars. Ive heard of many others having issues and there are YouTube videos on how to connect it. Really shame they cant label the ports so you know how to do it first time.The DI resin didn’t last ver long that came with the unit (~100ltr) but resin is cheap and readily available. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/193586766-finest-filters-reverse-osmosis-ro-unit-with-booster-pump-di](https://www.desertcart.vn/products/193586766-finest-filters-reverse-osmosis-ro-unit-with-booster-pump-di) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-18*
