🆚 Under-Sink Systems Vs Other Filter Types of Water FiltersĪ filtration system installed underneath your sink is only one of the types of water filters you can buy.īelow, we’ve listed some of the other types of water filtration options, and how these compare to under-sink units. Under-sink RO systems also remove beneficial minerals and salts, like calcium and magnesium, from water.Ĭheck out this post to learn about the best under sink filters for use with well water. This enables the RO system to produce pure water, but there are some disadvantages to this – water is wasted in the RO process, and healthy minerals are removed.Ī specialty under-sink filter system might be capable of removing additional contaminants, like: Semi-permeable membranes are combined with other RO filters, like carbon and sediment filters, in an under-sink RO system. These membranes have a pore size of 0.0001 microns and are capable of trapping most existing contaminants, from heavy metals to bacteria and everything in between. Semi-permeable membranes are found in RO under-sink filters. UV purifiers are typically installed in a whole house filter system, but they can also be used as add-ons to single- or multi-stage under-sink filtration units. UV can only target living organisms, and can’t be used to physically remove impurities. Instead, they send ultraviolet light into water, which damages the DNA of microorganisms like bacteria and viruses, preventing them from causing harm. UV purifiers aren’t technically water filters, as they don’t remove contaminants with a filtration process. These filters typically have a micron rating of 0.5-1.0, so they’re capable of removing tiny contaminants that might slip through the pores of other filters, like cysts and bacteria.īecause of their compacted design, carbon block filters have a longer contact with water than activated carbon filters, which allows them to trap more contaminants at once. Carbon Block FiltersĬarbon block filters are made from powdered carbon, compacted together into a solid block. The standard pore size of a sediment filter is 5-10 microns, meaning that contaminants larger than 5-10 microns are trapped, while smaller contaminants can pass through (these will be trapped in later filter stages). The three common types of sediment filters are depth, surface, and absorptive filters. Sediment filters are typically the first filter stage in multi-stage or reverse osmosis under-sink filters.Ī sediment filter traps large particles of sediment, dirt, dust, and rust, preventing them from damaging later filter stages. Now you know the different under-sink filter models, let’s look at the types of water filters that could be included in these systems. 📰 The Different Types of Under-Sink Water Filters This means they don’t need to be connected to an electricity supply, and they provide almost instant access to filtered water. Under-sink filtration systems rely on water pressure to send water through the filter media. When water leaves the system, it has been filtered – so any harmful contaminants have been removed.
Water flows through the filter media, and contaminants become trapped inside the filter. Under-sink water filters are units that are installed underneath your kitchen sink, with the purpose of delivering clean drinking water out of your faucet.Īn under-sink filtration system intercepts your existing cold water line. 🧠Types of Under-Sink Water Filters FAQs.
