 Pre-Filtration (Stage 1, 2 & 3) - recommended change every 6-12 months

Pre-filter lifetime can be reduced as a result of the level of turbidity and sediment in the feed water. The BMB HP-105 LX Reverse Osmosis System uses high performance pre-filters. Although the pre-filters used in this system are fully efficient in removing chlorine and sediment, they do much more.

First, the pre-filters for this system will remove sediment down to 0.5 microns which will more thoroughly protect the RO membrane.

Second, the pre-filters use coconut shell powder carbon instead of granule or block carbon (used in traditional systems) which has up to 10 million times more surface area for greater absorption rates and much longer lifetime.

Third, the pre-filters in this system are also designed to reduce heavy metals such as iron, manganese and rust which can also damage the RO membrane.

Reverse Osmosis Membrane (Stage 4) - recommended change every 12 - 36 months

Reverse Osmosis is the most advanced technology of water purification in use today. The technique uses a nanotechnology enabled semipermeable membrane which can reduce or remove most harmful impurities found in tap and well water including: microorganisms, nitrates, heavy metals, fluoride, insecticides and much more. The BMB HP-105 LX uses the industry leading, USA made, DOW Filmtec Membranes for solid reliability and performance. The double o-ring housings ensure no leaking problems, filters and pump and other components are made in Taiwan with top end manufacturing quality with NSF certification.

The table below lists the performance of specific contaminants. This is only a partial list of the virtually hundreds of thousands of contaminants that Reverse Osmosis can filter.

Estimated Reverse Osmosis Rejection Percentages * Figures given above are estimates of normal performance, under normal conditions and water.

At the heart of every Reverse Osmosis system is the membrane filter. The membrane filter consists of microporous, semipermeable membrane sheets. The average pore sizes on the RO membrane is in the range of 0.0005 mm (0.5 nanometers). The membrane filter has one water inlet and two exits. The feed water first travels through the pre-filters and then to the membrane filter.

At the exit of the membrane filter one of the ports is the rejected waste water which is connected to the drain, while the other port is the purified water which is plumbed to the post-filters.

We recommend membranes are changed no longer than every 3 years or when the TDS reaches over 50ppm.

Post Filter (Stage 5) - recommended change every 6-12 months

The Post Filter is an NSF Certified Activated Granular Coconut Shell Carbon: NSF.

This coconut shell carbon that acts as a final polisher and mineraliser.


Upgrade Option - 150GPD Recomax Low Rejection RO Membrane

Save £££'s on your water bills by upgrading your membrane to a Recomax Low Rejection Membrane. RO Membranes filters water with a ratio of 3:1 (3 litres of waste water for 1 litre of purified water). However, with this membrane, for every 1 litre of purified water only 1 - 1.5 litres is waste water. Better for the environment by using less water but also saving you money from your electricity bills if you have water running on a meter.
