FAQs
Is The COMFEE’ 5-Stage Reverse Osmosis System Worth Buying In 2025?
You’ll find that the COMFEE’ 5-Stage Reverse Osmosis System offers strong value if you want to stop buying bottled water and get noticeably cleaner-tasting water at the tap. The unit is NSF Certified and is designed to remove common contaminants such as chlorine and lead, and the system claims a 75 GPD capacity (real-world output will depend on your water pressure and temperature).
With a 3-gallon storage tank and quiet operation, the system works well for typical household drinking and cooking needs. The retail price is about $169.99, but factor in the cost of replacement filters and possible extra fittings for your plumbing. Read user reviews: many people report big TDS drops and easy DIY installs, while a minority report housing failures or slow customer service. If you value affordability, certification, and good contaminant reduction, this unit is a solid choice—just make sure your under-sink space, water pressure, and maintenance plan match the system’s requirements.
How Hard Is Installation And What Maintenance Does It Require?
You can usually install the COMFEE’ 5-Stage Reverse Osmosis System yourself in about an hour if you’re comfortable with basic under-sink plumbing; the quick-fit connectors and clear instructions make it DIY-friendly. Some buyers needed an extra fitting or minor parts, so check your existing supply lines and be prepared to pick up a 1/4″ tube or adapter if required. For maintenance, prefilters are commonly changed every 6–12 months depending on your water usage and feed water quality, and the RO membrane typically lasts 2–3 years but may need earlier replacement if your TDS or sediment load is high. Use a TDS meter to monitor performance—if you see TDS creeping up, it’s time to change the membrane or prefilters.
When you first install, flush the system according to the manual to condition the membrane, and always turn off the water when changing filters. Keep spare O-rings and check the transparent first-stage housing visually for sediment.
If you prefer less hands-on upkeep, consider professional installation and schedule filter changes based on measured output rather than fixed dates.
Will The System Leak Or Cause Water Damage, And How Can You Prevent Problems?
Leak incidents are mentioned in some reviews, so you should assume risk and take straightforward precautions. Leaks often stem from loose fittings, damaged O-rings, cracked housings, or pressure spikes.
To reduce risk, mount the unit securely, hand-tighten and then gently snug fittings (don’t overtighten), inspect and lightly lubricate O-rings during filter changes, and verify all quick-connect tubes are fully seated. Install a small water alarm near the system and consider adding an automatic shutoff valve—many users reported avoiding major damage because of those add-ons.
Place the unit where you can access it easily for filter swaps and visual checks; a drip tray under the tank and housings adds extra protection. If you see any unusual noises, rapid tank fill/empty cycles, or persistent dampness, shut off the feed and inspect immediately. Finally, register the product and save seller/manufacturer contact info so you can pursue warranty support quickly if a component fails.
