AquaSafe AS430 20" Big Blue Single Carbon Whole of House Filtration System

The units size wise are essentially exactly the same, they have the same pressure rating and the cartridges fit both units. The Big White housings are much stronger though, built from a harder more dense material than the Big Blue units hence we offer a 10 year warranty with the Big White and a 3 year warranty with the Big Blue. The Big Blue are more popular due to price. If kept out of the weather and used in rural applications the Big Blue units should last as long as the Big White however we would recommend Big White units for town water or higher pressure applications.

Pressure gauges are a useful tool that can help to indicate when the system filters are blocked. For an accurate representation, a gauge is required before and after each filter. The pressure difference between them when the system is under normal or design flow indicates the pressure loss across the filter cartridge or how blocked it is. Most customers can assess when the water flow in the house changes, it may be time to change the filters.

Pre-filters are usually supplied with twin-filtration systems and are designed to remove sediment and other suspended materials prior to the carbon filter. This prevents the more expensive carbon filter from blocking allowing it to remove more difficult contaminants. The pre-filter is designed to protect the carbon filter.

Sediment filters are available in a number of different pore or micron sizes ranging from 0.3 to 50+ microns. They can also be absolute or nominal micron ratings.
