From Manufacturing to Intelligent Manufacturing: LONSID Delivers a Perfect Answer

With years of dedication to the water purification industry, LONSID has always centered on user needs, polished technologies and refined products. The Loong Water Purifier, developed through three years of meticulous research and innovation, has successfully passed the authoritative technical appraisal organized by China National Light Industry Council with its all-round technological innovations and robust product strength.

Based on in-depth surveys of tens of thousands of households, LONSID accurately identifies six prevalent problems of household water purification: limited under-kitchen installation space, cumbersome filter replacement requiring after-sales service, loud operating noise disturbing nightly rest, high filter replacement frequency and consumable costs, insufficient intelligence of water purification equipment, and leakage risks caused by excessive pipeline joints.

User demands clearly focus on large water flow, leak-proof safety, intelligent monitoring, easy filter replacement and quiet operation. All technical upgrades of the Loong Water Purifier are designed for humanization, practicality and long-term performance, fundamentally solving daily household water purification pain points.

In July 2026, LONSID held a technical achievement appraisal conference at its headquarters in Yueqing, Wenzhou, inviting professional experts from six authoritative institutions to conduct comprehensive evaluation and verification on the technologies of the Loong Water Purifier. Through persistent refinement and iterative optimization, LONSID has achieved all-round upgrades in water purification experience with seven original core technologies, making high-end water purification technology accessible to thousands of households.

1. Dual-stroke Filter Locking Device (Authorized Invention Patent)

Adopting an innovative 7-shaped vertical side-mounted design, it reduces the displacement space required for filter replacement from 30cm to 10cm. Users can replace the filter single-handedly without tools or after-sales appointments, realizing effortless self-maintenance.

2. Three-axis Six-direction Integrated Waterway System

The integrally formed filter seat reduces traditional 15-20 pipeline nodes to merely 6-7, greatly lowering water leakage risks. The operating noise is controlled within 42 decibels, winning dual authoritative certifications of Green Sound Noise Reduction and CQC Integrated Waterway System.

3. Multi-page Winding & Pulse Flushing Patented Technology

The optimized multi-page winding membrane structure expands the effective filtration area and improves water purification efficiency. Combined with pulse flushing and pure water backflow technology, it effectively inhibits membrane crystallization and removes scale. This technology boosts the RO filter service life by 50% and scale removal efficiency by 40%, significantly cutting long-term consumable costs.

4. Integrated Flowmeter and Check Valve Structure (Authorized Utility Model Patent)

Breaking the traditional split design, the valve core component is built into the flowmeter main body with integral molding, eliminating hidden dangers of external pipelines. The product volume is reduced by 40% and assembly efficiency increased by 50%, bringing the water leakage risk close to zero.

5. AI Adaptive Pre-flushing Control Technology

Equipped with a digital twin water quality prediction model, it real-timely monitors water production volume, shutdown duration and raw water TDS data, dynamically calculates residual salt concentration, and automatically matches the optimal flushing strategy for adaptive and on-demand flushing.

6. Thin-wall Reinforced Modified PP Filter Shell

Optimized via finite element simulation, the structure reduces the shell weight by 26% while ensuring structural strength. Adopting high-performance modified PP material, it achieves a water hammer resistance life of 200,000 times, double the national standard, greatly enhancing product durability.

7. IoT Cloud AI Filter Life Prediction Technology

Integrating three-dimensional data of water production, pump operating duration and raw water TDS, the self-adaptive attenuation algorithm dynamically corrects the filter life curve and supports OTA online upgrade. Featuring 24/7 intelligent monitoring, it automatically cuts off water and power in case of leakage, with sound-light alarm and mini-program push notifications to prevent potential safety hazards in advance.

A qualified premium product ultimately serves users and real-life scenarios. Since its mass production and launch in 2024, the LONSID Loong Water Purifier has sold over one million units, guarding the water safety of millions of households nationwide.

From traditional manufacturing to intelligent manufacturing, LONSID always adheres to its original aspiration. With cutting-edge technologies, reliable quality and humanized experience, it builds a solid line of defense for household drinking water safety for every family.
