Reverse Osmosis Vs. Whole House Water Filter

When one wishes to obtain perfectly biocompatible drinking water, it is often necessary to proceed with the acquisition of a reverse osmosis system or any filtration system. But how does one differ from the other?

What are the differences between Reverse Osmosis Systems and Whole House Water Filters? Reverse osmosis is a POU (point of use) system installed under the kitchen sink to treat water for drinking and cooking purposes. A whole house filter is a POE (point of entry) system installed at the main water line to treat water for the entire home. Whole house filters allow a much higher flow rate and is designed to treat water for general usage such as cleaning, bathing and laundry applications. Whole house systems treat contaminants with filtration micron sizes ranging from 10-30 microns. Due to the larger micron size, it allows water to be quickly filtered from the main water line, throughout the entire home and into every faucet.

The water we consume for drinking and cooking should be filtered more carefully to guarantee contaminant free drinking water. Whole house systems work in general to filter more specific contaminants from the entire home while Reverse Osmosis specializes in removing a broad range of contaminants for drinking. Let us discuss in further detail the main differences between both types of filtration.

Reverse Osmosis Whole House Water Filter
Application POU (Point of use) POE (Point of entry)
Filtration Size 0.0001 micron 10 – 30 micron
Use for Drinking or Cooking Bathroom, Shower, Cleaning and Gardening
Avg Flow Rate 45 Gallons Per Day 10 Gallons Per Minute

The Most Efficient Drinking Water Filters

reverse osmosisReverse osmosis is the most convenient and effective method of water filtration. It is the same filtration used for bottled water and was first designed to desalinate seawater. The filter size of the RO membrane is rated at 0.0001 micron size. Water is pushed through the membrane and anything larger than that size is not allowed to pass through. This filters up to 99% of all contaminants that are in the water including nitrate, arsenic, chromium, fluoride, radon and other contaminants that whole house filters cannot remove. This leaves us with the purest quality water possible, straight from our faucet!

Some people may think, well I thought my city’s tap water was safe to drink?

This may have been more accurate years back when we had less chemicals added into our water such as chlorine, chloramines or fluoride. Currently, the most popular method of filtering water for the city is by adding chemicals into the water to kill waterborne disease. Yes, this method is actually effective in killing bacteria and viruses but it also poses a set of other health concerns. Chemicals in our water such as chlorine or chloramines create toxic byproducts with the natural elements that are in the water, posing a handful of health risks. Whole house systems are capable of treating chlorine and chloramines but are not capable of removing specific contaminants such as nitrate, arsenic, chromium and many more.

Reverse Osmosis systems are placed underneath the sink and store purified water to be readily available at all times. It uses a designated drinking water faucet to deliver high quality purified water. RO systems are low maintenance systems that only require annual filter changes
