Filtration Systems

The Philips AUT4030R400 400 GPD Reverse Osmosis Under-Sink Water Filtration System is a compact, tankless Direct Flow solution featuring an efficient 4-stage filtration system. Its reverse osmosis membrane provides filtration down to 0.0001 micron, helping reduce chlorine, heavy metals, pesticides, bacteria, viruses, VOCs, microplastics and water hardness. The slim design, measuring only 114 mm wide, allows convenient installation in limited under-sink spaces without the need for a separate storage tank. The system offers two filtration modes through its dedicated faucet: filtered water at up to 2 L/min and RO-purified water at approximately 1.1 L/min. It uses a 3-in-1 filter with coconut-shell activated carbon together with the RO membrane, while an integrated filter-life indicator reminds the user when replacement is required. The official Philips specifications indicate a filter life of approximately 12 months for the 3-in-1 cartridge and 36 months for the RO membrane.

The Philips AquaShield AUT7006 800 GPD Reverse Osmosis Under-Sink Water Filtration System is a high-performance 5-stage, tankless RO system designed to provide deep filtration directly from the dedicated faucet. Its advanced filtration combines an innovative 4-in-1 PC filter with an 800 GPD RO membrane, achieving filtration down to 0.0001 micron. According to Philips, the system can reduce up to 99.999% of bacteria and viruses and up to 99% of chlorine, pesticides, water hardness and heavy metals under the specified test conditions. The tankless design delivers filtered water without requiring a separate storage tank, providing a fast flow rate of up to 2.1 L/min while saving valuable under-sink space. A smart faucet provides a filter replacement reminder, while the system also features automatic flushing for convenient maintenance. The long-life 4-in-1 PC filter is rated for 12–24 months, while the RO membrane provides an estimated service life of 48–60 months, depending on water quality and daily consumption.

The ECOSOFT P’URE KPOMPROECO is a complete pressure booster pump kit designed for domestic reverse osmosis systems operating with low or unstable mains water pressure. By increasing the feed pressure to the RO membrane, it helps the filtration system operate efficiently and maintain consistent purified-water production. ECOSOFT recommends the pump particularly when mains pressure is below 3 bar or unstable, and the unit can also be installed with compatible reverse osmosis systems from other manufacturers. The unit incorporates automatic low- and high-pressure switches, automatically controlling pump operation according to the water supply and storage-tank status. The low-pressure protection stops the pump if the incoming water supply is interrupted, while the high-pressure switch stops operation when the RO storage tank is full. According to ECOSOFT, adequate pressure can also contribute to 30–50% water savings compared with operation under insufficient pressure. The kit includes the necessary tubing and fittings for installation.
