Xiaomi Mijia N800G RO1: Smart Water Purifier Review

Xiaomi Mijia Smart Water Purifier N800G RO1: Smarter, Cleaner, Built to Last
Hey there, Xiaomi fam! In a world where safe drinking water is becoming a bit of a luxury, Xiaomi’s stepped up with something seriously cool: the Mijia Smart Water Purifier N800G RO1. Launched on October 18, 2025, this smart purifier is all about making your daily hydration crystal clear, worry-free, and, let’s be honest, a whole lot easier. Whether you’re cooking up a storm, brewing your morning tea, or just need a refreshing sip, the N800G RO1 ensures every drop is pure and pristine.
Smart Innovation for Everyday Living
Let’s face it, clean water shouldn’t be a question mark. From pesky heavy metals to funky tastes, our tap water can be a bit of a gamble. The Mijia Smart Water Purifier N800G RO1 is here to change that, wrapping cutting-edge tech in a user-friendly package. It’s perfect for busy professionals, parents keeping an eye on family health, or anyone who just values their well-being. This isn’t just a filter; it’s a reliable, connected solution for your home.
One of its standout features is the super-fast 800G flow rate. We’re talking up to 2.6 liters per minute, which means filling a 150ml glass takes a mere 3.5 seconds. And forget about those storage tanks that can sometimes become breeding grounds for bacteria – this system integrates directly into your water line. Plus, it comes with its own smart faucet that seamlessly hooks into your existing Xiaomi ecosystem.

Deep Filtration for Ultimate Purity
At the heart of the N800G RO1 is a serious six-stage Reverse Osmosis (RO) filtration system. This bad boy tackles up to 99.99% of contaminants. We’re talking rust, chlorine, bacteria, heavy metals, and even BPA. That means the water is safe for everyone, including pregnant women and little ones. What’s really impressive is the longevity of these RO filters – up to three years, or 4,000 liters of total capacity. This translates to a whopping 70% cost reduction on maintenance compared to older models. Under normal use, it consistently delivers pure water with an unbeatable taste.
Key Filtration Stages:
- Stage 1: Removes larger particles like rust and sediment.
- Stage 2: Activated carbon filters out chlorine and odors.
- Stage 3 & 4: RO membranes tackle heavy metals, bacteria, and viruses.
- Stage 5: Post-carbon filter further polishes taste and removes any residual impurities.
- Stage 6: Mineralization stage (optional, depending on specific model variant) adds back beneficial minerals.
Smart Monitoring & Seamless Connectivity
No more guessing games about filter life! The N800G RO1 syncs with the Xiaomi Home app, giving you real-time updates on filter status right on your smartphone. You’ll get push notifications when it’s time for a change. And for an extra visual cue, the smart faucet features an LED ring that turns orange as a reminder.

It also supports RFID and NFC chips for automatic filter identification, meaning the purifier knows exactly which filter is installed and its lifespan. Plus, the built-in TDS (Total Dissolved Solids) meter lets you instantly verify water quality. These features are all about saving you time and ensuring efficiency, all while a low-noise pump hums away almost silently.
Effortless Installation and Use
Simplicity is key, and Xiaomi’s nailed it here. Installing the RO1 filter is a breeze: just align it with the position mark, push, and twist clockwise to lock. It’s done in seconds, no tools or plumbers required! The compact design slides neatly under your sink, making it ideal for kitchens where space is a premium. The smart faucet itself is a nice touch, with an LED display showing TDS and flow rate – a futuristic yet totally functional addition.
Built to Last, Designed for Health
Under standard conditions, you can expect the RO filter to last up to three years. Of course, this can vary based on your local water quality and how much you use it, but the app keeps you perfectly informed. The N800G RO1 is more than just a gadget; it’s a solid investment in your family’s health. It purifies water for cooking, drinking, and making your favorite beverages, stripping out chlorine for a cleaner, natural taste.
It’s designed to fit right into your smart home, complementing other Mijia devices like robot vacuums or smart lights. Plus, it boasts Level 1 water efficiency certifications and uses BPA-free materials, reinforcing its commitment to both sustainability and your well-being.
