This article will give you a comprehensive understanding of the types of outdoor water filters in Malaysia, including their advantages and disadvantages, so that you can make an informed choice according to your own needs! In fact, there are only 3 types of technologies: sand filter, canvas filter and membrane filter.

Sand Filter

Sand Filter uses a multi-layered sand filtration process to remove particles, sediments, and various impurities in tap water with a density greater than 10 microns. However, as a consequence, the water that flows out after filtration appears relatively contaminated.

This traditional technology has a history of over 50 years and it’s outdated. Its maintenance and upkeep are somewhat similar to membrane filter, with regular flushing and backwash. The difference is its backwash requires longer time with at least 15 minutes or more and the painful part is much water is wasted in this process.

Additionally, maintenance costs are relatively high as the sand within the sand filter needs to be replaced every year, which means the entire unit needs to be replaced to maintain the filtration effectiveness.

Canvas Filter

Canvas Filter uses high-density canvas material for filtration. It has a slightly better filtering effect compared to the sand filter, as it can remove harmful impurities with a density equivalent to 10 microns. However, maintenance for this outdoor water filter is more complicated. It cannot flush or backwash the accumulated harmful impurities in the filter. As a result, periodic on-site cleaning and filter cartridge replacement by professionals are necessary for every 6 months or 1 year, which can be quite costly.
